Plant tissues
This document discusses different plant tissues. It introduces simple tissues like parenchyma, collenchyma and sclerenchyma. Parenchyma tissue stores food and helps with transport. Collenchyma provides structure and support to leaves while some cells perform photosynthesis. Sclerenchyma provides strength and protects the plant body. Complex tissues discussed are xylem and phloem. Xylem conducts water and minerals upwards while phloem transports food throughout the plant. These tissues perform critical functions for plant growth and sustainability.
Plant tissues slides
The document describes the four main tissue systems in plants: dermal, ground, vascular, and meristematic tissue. Dermal tissue consists of the epidermis and periderm, which cover and protect the plant. Ground tissue includes parenchyma, collenchyma, and sclerenchyma cells that provide structure and storage. Vascular tissue is composed of xylem and phloem that transport water and nutrients. Xylem contains tracheids and vessels, while phloem consists of sieve tubes and companion cells.
Tissues
There are four main types of tissues in plants and animals:
1. Meristematic tissue, found at growing tips of stems and roots, is composed of actively dividing cells responsible for growth.
2. Permanent tissues have differentiated cells that perform specific functions and do not divide. These include simple tissues like parenchyma and complex tissues like xylem and phloem.
3. The four main animal tissues are epithelial, connective, muscle and nervous tissue. Epithelial tissue lines surfaces, connective tissue connects and supports, muscular tissue enables movement, and nervous tissue conducts electrical signals.
Plant tissues
Plant tissues are divided into meristematic and permanent tissues. Meristematic tissues are actively dividing cells responsible for growth. They include apical, lateral and intercalary meristems. Permanent tissues stop dividing and perform specific functions, including dermal tissues like the epidermis and periderm, ground tissues like parenchyma, collenchyma and sclerenchyma, and vascular tissues that transport water and nutrients throughout the plant, such as xylem and phloem. Xylem transports water upward and is composed of tracheids, vessels and fibers. Phloem transports food downward and contains sieve tubes, companion cells and fibers.
Permanent Tissues of Plants
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.

plant tissue
Plant organs such as roots, stems, and leaves are composed of tissues which are groups of cells that perform specialized functions. The three main tissue types are dermal tissue (epidermis), ground tissue (parenchyma, collenchyma, sclerenchyma), and vascular tissue (xylem and phloem). The epidermis forms the outer protective layer, ground tissues fill the interior and provide support, and vascular tissues transport water, minerals, and organic compounds throughout the plant. Each tissue contains further specialized cell types that contribute to the plant's growth, protection, nutrient transport, and other processes.
Tissues and types of plant tissues
The document discusses the different types of plant tissues. There are three main types of plant tissues: dermal tissue (epidermis), ground tissue (parenchyma, collenchyma, sclerenchyma), and vascular tissue (xylem and phloem). Xylem tissue transports water and minerals throughout the plant. Phloem tissue transports sugars and nutrients. Meristematic tissue consists of actively dividing cells and is responsible for growth in plants. As cells differentiate, they take on specialized roles and functions as part of the permanent tissues that make up the main tissue systems in plants.

Plant tissues
This document discusses plant tissues. There are two main types of plant tissues: meristematic and permanent tissues. Meristematic tissues are undifferentiated and can divide, while permanent tissues have differentiated and lost the ability to divide. The three main permanent tissues are dermal/protective, fundamental/supportive, and vascular/conductive tissues. Dermal tissue covers the plant, fundamental tissue provides structure and storage, and vascular tissue transports water and nutrients. Within these tissues are cell types specialized for different functions like photosynthesis, support, and long-distance transport.
Meristematic tissue
1) Meristematic tissue contains undifferentiated cells that actively divide throughout a plant's life to form specialized structures like leaves, flowers, roots and shoots.
2) The tissue is usually found at root and shoot tips and helps increase plant length and girth.
3) Meristematic tissue is classified based on origin, development stage, position and function - including apical, intercalary and lateral meristems that contribute to height, internodal length and thickness.
Plant tissues (part ii) copy
This document describes plant tissues, specifically complex tissues like xylem and phloem. It details that xylem transports water and minerals up the plant and is composed of tracheids, vessels, fibers and parenchyma cells. Phloem transports sugar and foods down the plant for growth and storage. In angiosperms, phloem is composed of sieve tubes, companion cells, parenchyma and fibers. Sieve tubes are long tubes that transport fluids between cells. Companion cells provide support to the sieve tubes.
Plant tissues
There are five main types of plant tissues: parenchyma, collenchyma, sclerenchyma, xylem, and phloem. Parenchyma is made of thin-walled cells that perform photosynthesis and store food. Collenchyma provides flexibility and support to plant structures. Sclerenchyma is made of thickened, non-living cells that provide strength and support. Xylem and phloem make up the vascular tissue and transport water, minerals, and food throughout the plant.

Permanent tissues include epidermal tissue, ground tissue and vascular tissue. Epidermal tissue forms the outer layer of stems, leaves and roots. Ground tissue includes parenchyma, collenchyma and sclerenchyma cells which provide support. Vascular tissue comprises xylem and phloem. Xylem transports water and minerals upwards from the roots through hollow vessels. Phloem transports sugars made by photosynthesis to all parts of the plant through sieve tubes.
PLANT TISSUES.pptx
The document discusses plant tissues and types of plant tissues. There are three main types of plant tissues: dermal tissue (epidermis), ground tissue (parenchyma, collenchyma, sclerenchyma), and vascular tissue (xylem and phloem). Meristematic tissue consists of actively dividing cells and is responsible for growth in plants. Meristematic tissue differentiates into permanent tissues, which include simple tissues like parenchyma, collenchyma, and sclerenchyma, as well as complex vascular tissues.
Different types of plant cells
Parenchyma, collenchyma, sclerenchyma, phloem, and xylem are the fundamental tissues in plants. Parenchyma cells perform photosynthesis and store products. Collenchyma and sclerenchyma provide structural support. Phloem transports food throughout the plant via sieve tubes and companion cells. Xylem transports water and minerals upwards via tracheids and vessels. These tissues work together to support and transport nutrients and water in plants.
Tissue
1. Plant tissues are classified as meristematic and permanent tissues. Meristematic tissues are dividing tissues located at specific regions that allow plant growth.
2. Meristematic tissues are further classified as apical, lateral, and intercalary. Permanent tissues are formed when meristematic cells differentiate and take up permanent roles.
3. Common permanent tissues include parenchyma, collenchyma, sclerenchyma, epidermal tissues, xylem and phloem. Epidermal tissues form the plant outer layer and regulate gas exchange through stomata. Xylem and phloem transport water and nutrients.

It then discusses plant cells, tissues, and the three main tissue systems - epidermal, ground, and vascular. Specific plant structures like stems, leaves, flowers, fruits, and seeds are also summarized in terms of their structure and function. The document provides a comprehensive introduction to plant anatomy and physiology relevant to the study of herbal medicines.
Plant-Structure-and-Growthdevelopmwnt.pptx
Plants have three main organ systems - roots, stems, and leaves. Roots absorb water and minerals from the soil and anchor the plant, while stems provide structure and transport water and nutrients between roots and leaves. Leaves use sunlight, water and carbon dioxide to produce food for the plant through photosynthesis.
Plant organs are made of three main tissue types - dermal tissue which covers the plant, vascular tissue which transports water and nutrients, and ground tissue for photosynthesis, storage and support. Vascular tissue specifically contains xylem and phloem. Xylem transports water and minerals upwards while phloem transports sugars downward.
The basic building blocks of plant tissues are cells. Plant cells have additional
Chapter 23 Lecture- Roots, Stems, Leaves
The document summarizes plant structure and function. It describes how plants have three main organs - roots, stems, and leaves. Roots absorb water and nutrients from the soil. Stems provide structure, transport, and protection. Leaves are the main sites of photosynthesis and gas exchange. Plants have specialized tissues including dermal tissue, vascular tissue, and ground tissue. Transport of water and nutrients occurs through xylem and phloem tissue in the vascular system.
Tissues
There are four main types of tissues in both plants and animals: meristematic tissue, permanent tissue, epithelial tissue, and connective tissue.
Meristematic tissue consists of actively dividing cells and is found at growth points in plants such as the root tip and shoot tip. Permanent tissues, including complex tissues like xylem and phloem, are composed of differentiated cells that have lost the ability to divide. Epithelial tissues cover the internal and external surfaces of both plants and animals, while connective tissues provide structure and binding functions.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.
