Living organisms are made of cells.
In unicellular organisms, a single cell performs all basic functions.
In Amoeba, a single cell carries out movement, intake of food, gaseous exchange and excretion.
Amoeba is example of unicellular cells.
Multi- cellular organisms there are millions of cells.
Each specialised function is taken up by a different group of cells.
Cells that carry out only a particular function, they do it very efficiently.
In human beings, muscle cells contract and relax to cause movement.
In human beings, nerve cells carry messages
In human beings, blood flows to transport oxygen, food, hormones and waste material and so on.
In plants, vascular tissues conduct food and water from one part of the plant to other parts.
Multi-cellular organisms show division of labour.
Definition: Cells specialising in one function are grouped together in the body to carry a particular function by a cluster of cells at a definite place in the body. This cluster of cells, is called a tissues.
These tissues are arranged and designed so as to give the highest possible efficiency of function.
A group of cells that are similar in structure and/or work together to achieve a particular function forms a tissue.
Difference
Plant Tissue: Plants are stationary or fixed, they don’t move. They have to be upright, they have a large quantity of supportive tissue. The supportive tissue generally has dead cells. The growth in plants is limited to certain regions. Some tissues in plants divide throughout their life. The structural organisation of organs and organ systems is far more specialised and localised in complex animals. Organ system design is for sedentary existence in plants
Animal Tissue: Animals move around in search of food, mates and shelter. They consume more energy as compared to plants. Most of the tissues they contain are living. The growth in animals is not limited to certain regions. Cell growth in animals is more uniform. So there is no such demarcation of dividing and non- dividing regions in animals.
The structural organisation of organs and organ systems is not far more specialised and localised than in very complex plants. Organ system design for active locomotion in animals.
In plant anatomy, tissues are categorized broadly into three tissue systems: the epidermis, the ground tissue, and the vascular tissue. Epidermis - Cells forming the outer surface of the leaves and of the young plant body. Vascular tissue - The primary components of vascular tissue are the xylem and phloem.

The cells derived from root apical and shoot-apical meristems and cambium differentiate and mature to perform specific functions. This act leading to maturation is termed as differentiation. During differentiation, cells undergo few to major structural changes both in their cell walls and protoplasm. The living differentiated cells, that by now have lost the capacity to divide can regain the capacity of division under certain conditions. This phenomenon is termed as dedifferentiation. For example, formation of meristems – interfascicular cambium and cork cambium from fully differentiated parenchyma cells. While doing so, such meristems / tissues are able to divide and produce cells that once again lose the capacity to divide but mature to perform specific functions, i.e., get redifferentiated.

Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.

Tom Selleck Health: A Comprehensive Look at the Iconic Actor’s Wellness Journeygreendigital
Tom Selleck, an enduring figure in Hollywood. has captivated audiences for decades with his rugged charm, iconic moustache. and memorable roles in television and film. From his breakout role as Thomas Magnum in Magnum P.I. to his current portrayal of Frank Reagan in Blue Bloods. Selleck's career has spanned over 50 years. But beyond his professional achievements. fans have often been curious about Tom Selleck Health. especially as he has aged in the public eye.
Follow us on: Pinterest
Introduction
Many have been interested in Tom Selleck health. not only because of his enduring presence on screen but also because of the challenges. and lifestyle choices he has faced and made over the years. This article delves into the various aspects of Tom Selleck health. exploring his fitness regimen, diet, mental health. and the challenges he has encountered as he ages. We'll look at how he maintains his well-being. the health issues he has faced, and his approach to ageing .
Early Life and Career
Childhood and Athletic Beginnings
Tom Selleck was born on January 29, 1945, in Detroit, Michigan, and grew up in Sherman Oaks, California. From an early age, he was involved in sports, particularly basketball. which played a significant role in his physical development. His athletic pursuits continued into college. where he attended the University of Southern California (USC) on a basketball scholarship. This early involvement in sports laid a strong foundation for his physical health and disciplined lifestyle.
Transition to Acting
Selleck's transition from an athlete to an actor came with its physical demands. His first significant role in "Magnum P.I." required him to perform various stunts and maintain a fit appearance. This role, which he played from 1980 to 1988. necessitated a rigorous fitness routine to meet the show's demands. setting the stage for his long-term commitment to health and wellness.
Fitness Regimen
Workout Routine
Tom Selleck health and fitness regimen has evolved. adapting to his changing roles and age. During his "Magnum, P.I." days. Selleck's workouts were intense and focused on building and maintaining muscle mass. His routine included weightlifting, cardiovascular exercises. and specific training for the stunts he performed on the show.
Selleck adjusted his fitness routine as he aged to suit his body's needs. Today, his workouts focus on maintaining flexibility, strength, and cardiovascular health. He incorporates low-impact exercises such as swimming, walking, and light weightlifting. This balanced approach helps him stay fit without putting undue strain on his joints and muscles.
Importance of Flexibility and Mobility
In recent years, Selleck has emphasized the importance of flexibility and mobility in his fitness regimen. Understanding the natural decline in muscle mass and joint flexibility with age. he includes stretching and yoga in his routine. These practices help prevent injuries, improve posture, and maintain mobilit

Plant Tissues
Plants are stationary or fixed – they don’t move. Most of the tissues they
have are supportive, which provides them with structural strength.
Most of the plant tissues are dead, since dead cells can provide
mechanical strength as easily as live ones, and need less maintenance.
Animals on the other hand move around in search of food, mates and
shelter. They consume more energy as compared to plants. Most of the
tissues they contain are living.
Another difference between animals and plants is in the pattern of growth.
The growth in plants is limited to certain regions, while this is not so in
animals.
There are some tissues in plants that divide throughout their life. These
tissues are localised in certain regions.
Based on the dividing capacity of the tissues, various plant tissues can be
classified as growing or meristematic tissue and permanent tissue.
Cell growth in animals is more uniform. So, there is no such demarcation
of dividing and non-dividing regions in animals.
The structural organisation of organs and organ systems is far more
specialised and localised in complex animals than even in very complex
plants. This fundamental difference reflects the different modes of life
pursued by these two major groups of organisms, particularly in their
different feeding methods.
Also, they are differently adapted for a sedentary existence on one hand
(plants) and active locomotion on the other (animals), contributing to this
difference in organ system design.
Meristematic Tissue
The growth of plants occurs only in certain specific regions. This is because
the dividing tissue, also known as meristematic tissue, is located only at
these points.
Depending on the region where they are present, meristematic tissues are
classified as apical, lateral and intercalary.
New cells produced by meristem are initially like those of meristem itself,
but as they grow and mature, their characteristics slowly change and they
become differentiated as components of other tissues.
2. Course code:EDU246 Education Department
Course name : Botany
1. Apical meristem is present at the growing tips of stems and roots and
increases the length of the stem and the root.
2. The girth of the stem or root increases due to lateral meristem
(cambium).
3. Intercalary meristem is the meristem at the base of the leaves or
internodes (on either side of the node) on twigs.
As the cells of this tissue are very active, they have dense cytoplasm, thin
cellulose walls and prominent nuclei. They lack vacuoles.
Permanent Tissue
What happens to the cells formed by meristematic tissue? They take up a
specific role and lose the ability to divide. As a result, they form a
permanent tissue.
3. Course code:EDU246 Education Department
Course name : Botany
This process of taking up a permanent shape, size, and a function is
called differentiation. Cells of meristematic tissue differentiate to form
different types of permanent tissue.
Simple Permanent Tissue
Parenchyma
4. Course code:EDU246 Education Department
Course name : Botany
A few layers of cells form the basic packing tissue. This tissue is
parenchyma, a type of permanent tissue. It consists of
relatively unspecialised cells with thin cell walls.
They are live cells. They are usually loosely packed, so that large spaces
between cells (intercellular spaces) are found in this tissue.
Chlorenchyma
This tissue provides support to plants and also stores food. In some
situations, it contains chlorophyll and performs photosynthesis, and then it
is called chlorenchyma.
Aerenchyma
In aquatic plants, large air cavities are present in parenchyma to
give buoyancy to the plants to help them float. Such a parenchyma type is
called aerenchyma. The parenchyma of stems and roots also stores
nutrients and water.
Collenchyma
The flexibility in plants is due to another permanent tissue, collenchyma. It
allows easy bending in various parts of a plant (leaf, stem) without
breaking. It also provides mechanical support to plants. We can find this
tissue in leaf stalks below the epidermis. The cells of this tissue are living,
elongated and irregularly thickened at the corners. There is very little
intercellular space.
Sclerenchyma
Yet another type of permanent tissue is sclerenchyma. It is the tissue which
makes the plant hard and stiff. We have seen the husk of a coconut. It is
made of sclerenchymatous tissue. The cells of this tissue are dead. They
are long and narrow as the walls are thickened due to lignin (a chemical
substance which acts as cement and hardens them). Often these walls are
so thick that there is no internal space inside the cell. This tissue is
present in stems, around vascular bundles, in the veins of leaves and in the
hard covering of seeds and nuts. It provides strength to the plant parts.
Epidermis
5. Course code:EDU246 Education Department
Course name : Botany
What you observe is the outermost layer of cells, called epidermis. The
epidermis is usually made of a single layer of cells.
In some plants living in very dry habitats, the Epidermis may be thicker
since protection against water loss is critical.
The entire surface of a plant has this outer covering of epidermis. It
protects all the parts of the plant.
Epidermal cells on the aerial parts of the plant often secrete a waxy, water-
resistant layer on their outer surface. This aids in protection against loss of
water, mechanical injury and invasion by parasitic fungi.
Since it has a protective role to play, cells of epidermal tissue form a
continuous layer without intercellular spaces.
Most epidermal cells are relatively flat. Often their outer and side walls are
thicker than the inner wall.
Small pores in the epidermis of the leaf are called stomata. Stomata are
enclosed by two kidney-shaped cells called guard cells. They are
necessary for exchanging gases with the atmosphere.
Transpiration (loss of water in the form of water vapour) also takes place
through stomata
Epidermal cells of the roots, whose function is water absorption,
commonly bear long hair-like parts that greatly increase the total
absorptive surface area.
In some plants like desert plants, epidermis has a thick waxy coating
of cutin (chemical substance with waterproof quality) on its outer surface.
As plants grow older, the outer protective tissue undergoes certain
changes. A strip of secondary meristem replaces the epidermis of the
stem. Cells on the outside are cut off from this layer. This forms the
several-layer thick cork or the bark of the tree. Cells of cork are dead and
compactly arranged without intercellular spaces. They also have a chemical
called suberin in their walls that makes them impervious to gases and
water
Complex Permanent Tissue
The different types of tissues we have discussed until now are all made
of one type of cells, which look like each other. Such tissues are called
simple permanent tissue. Yet another type of permanent tissue is complex
tissue.
Complex tissues are made of more than one type of cells. All these cells
coordinate to perform a common function.
6. Course code:EDU246 Education Department
Course name : Botany
Xylem and phloem are examples of such complex tissues. They are both
conducting tissues and constitute a vascular bundle.
Vascular or conductive tissue is a distinctive feature of the complex plants,
one that has made possible their survival in the terrestrial environment.
8. Course code:EDU246 Education Department
Course name : Botany
Xylem
Xylem consists of tracheids, vessels, xylem parenchyma and xylem
fibres. The cells have thick walls, and many of them are dead cells.
Tracheids and vessels are tubular structures. This allows them to transport
water and minerals vertically.
The parenchyma stores food and helps in the sideways conduction of
water. Fibres are mainly supportive in function.
Phloem
Phloem is made up of four types of elements: sieve tubes, companion
cells, phloem fibres and the phloem parenchyma. Sieve tubes are
tubular cells with perforated walls.
Phloem is unlike xylem in that materials can move in both directions in it.
Phloem transports food from leaves to other Parts of the plant. Except for
phloem fibres, phloem cells are living cells.
