1) The document discusses the classification of living organisms into a hierarchy of kingdoms, phyla/divisions, classes, orders, families, genera, and species based on their characteristics and evolutionary relationships.
2) There are five main kingdoms - Monera, Protista, Fungi, Plantae, and Animalia. Plants and animals are further divided into smaller subgroups.
3) Classification helps organize the vast diversity of life forms into manageable groups for study. Scientific naming using binomial nomenclature allows organisms to be uniquely identified.

(May 29th, 2024) Advancements in Intravital Microscopy- Insights for Preclini...Scintica Instrumentation
Intravital microscopy (IVM) is a powerful tool utilized to study cellular behavior over time and space in vivo. Much of our understanding of cell biology has been accomplished using various in vitro and ex vivo methods; however, these studies do not necessarily reflect the natural dynamics of biological processes. Unlike traditional cell culture or fixed tissue imaging, IVM allows for the ultra-fast high-resolution imaging of cellular processes over time and space and were studied in its natural environment. Real-time visualization of biological processes in the context of an intact organism helps maintain physiological relevance and provide insights into the progression of disease, response to treatments or developmental processes.
In this webinar we give an overview of advanced applications of the IVM system in preclinical research. IVIM technology is a provider of all-in-one intravital microscopy systems and solutions optimized for in vivo imaging of live animal models at sub-micron resolution. The system’s unique features and user-friendly software enables researchers to probe fast dynamic biological processes such as immune cell tracking, cell-cell interaction as well as vascularization and tumor metastasis with exceptional detail. This webinar will also give an overview of IVM being utilized in drug development, offering a view into the intricate interaction between drugs/nanoparticles and tissues in vivo and allows for the evaluation of therapeutic intervention in a variety of tissues and organs. This interdisciplinary collaboration continues to drive the advancements of novel therapeutic strategies.
Richard's entangled aventures in wonderlandRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.
Multi-source connectivity as the driver of solar wind variability in the heli...Sérgio Sacani
The ambient solar wind that flls the heliosphere originates from multiple
sources in the solar corona and is highly structured. It is often described
as high-speed, relatively homogeneous, plasma streams from coronal
holes and slow-speed, highly variable, streams whose source regions are
under debate. A key goal of ESA/NASA’s Solar Orbiter mission is to identify
solar wind sources and understand what drives the complexity seen in the
heliosphere. By combining magnetic feld modelling and spectroscopic
techniques with high-resolution observations and measurements, we show
that the solar wind variability detected in situ by Solar Orbiter in March
2022 is driven by spatio-temporal changes in the magnetic connectivity to
multiple sources in the solar atmosphere. The magnetic feld footpoints
connected to the spacecraft moved from the boundaries of a coronal hole
to one active region (12961) and then across to another region (12957). This
is refected in the in situ measurements, which show the transition from fast
to highly Alfvénic then to slow solar wind that is disrupted by the arrival of
a coronal mass ejection. Our results describe solar wind variability at 0.5 au
but are applicable to near-Earth observatories.
A brief information about the SCOP protein database used in bioinformatics.
The Structural Classification of Proteins (SCOP) database is a comprehensive and authoritative resource for the structural and evolutionary relationships of proteins. It provides a detailed and curated classification of protein structures, grouping them into families, superfamilies, and folds based on their structural and sequence similarities.
THE IMPORTANCE OF MARTIAN ATMOSPHERE SAMPLE RETURN.Sérgio Sacani
The return of a sample of near-surface atmosphere from Mars would facilitate answers to several first-order science questions surrounding the formation and evolution of the planet. One of the important aspects of terrestrial planet formation in general is the role that primary atmospheres played in influencing the chemistry and structure of the planets and their antecedents. Studies of the martian atmosphere can be used to investigate the role of a primary atmosphere in its history. Atmosphere samples would also inform our understanding of the near-surface chemistry of the planet, and ultimately the prospects for life. High-precision isotopic analyses of constituent gases are needed to address these questions, requiring that the analyses are made on returned samples rather than in situ.
1. CHAPTER - 7
DIVERSITY IN LIVING
ORGANISMS
CLASS :- IX
MADE BY :- SHIVA PRASAD
SCHOOL :- K.V. 2. KALPAKKAM
2. 1) Need for classification of living organisms :-
Living organisms have evolved on the earth over millions of years.
There is a vast variety of living organisms. Living organisms show a
wide range of variations.
- Some microscopic bacteria are of a few micrometres in size and some
like whales and red wood trees are about 30 metres and 100 metres in
size.
- Some pine trees live for thousands of years while insects like
mosquitoes die within a few days.
- Some organisms are colourless and even transparent and some are
brightly coloured.
To understand and study all these organisms is impossible. If they are
arranged into different groups based on their similarities in
characteristics, then it is easier to study the different groups as a
whole.
Classification of living organisms :- The arranging of organisms
into different groups on the basis of the similarities in their
characteristics is called classification of living organisms.
3. 2) Basis of classification of living organisms :-
The main characteristics which are considered for
classification of living organisms into different groups are :-
- Whether they are made of prokaryotic or eukaryotic cells.
- Whether the cells occur singly or they are grouped
together and live as an indivisible group.
- Whether they produce their own food by photosynthesis
or get their food from outside.
- Of the organisms which produce their own food (plants)
what is the level of organisation of their body ?
- Of the animals what is the level of organisation of their
body and what are their special organs and their
functions ?
The characteristics used for classification of plants will be
different from the characteristics used for classification of
animals because plants make their own food and animals
get their food from outside.
4. 3) Classification and evolution :-
The present day complex living organisms have evolved
from the earlier simple forms due to the changes in their
body designs over millions of years.
The body designs of living organisms are gradually
changing due to the changes in environment and the need
to adapt themselves to the changes in the environment.
Some groups of organisms having ancient body designs
have not changed much during evolution and have simple
forms and structure. These organisms are called ‘primitive
or lower organisms’.
Some organisms have acquired their body designs
relatively recently and have complex forms and structure.
These organisms are called ‘advanced or higher
organisms’.
5. 4) The hierarchy of classification – Groups :-
Living organisms have been broadly classified into five main
kingdoms. They are :-
i) Monera ii) Protista iii) Fungi iv) Plante v) Animalia
Each kingdom has been further classified into smaller
sub - groups at various levels as :-
Kingdom
Phylum (for plants) / Division (for animals)
Class
Order
Family
Genus
Species
By arranging organisms on the basis of hierarchy and characteristics
into smaller and smaller groups we arrive at the basic unit of
classification called species.
Species :- is group of organisms which are similar enough to breed
and perpetuate.
6. 5) The Five Kingdom classification of living organisms :-
Organisms
Prokaryotes Eukaryotes
Unicellular Multicellular
Protista
With cell wall Without cell wall
Animalia

9. iii) Fungi :-
They are eukaryotic, unicellular or multicellular. They do not have
chlorophyll and cannot prepare their own food and are heterotrophs.

saprophytes. Some of them live in association with algae. They are
called lichens.
Eg :- Yeast, Aspergillus, Penicillium, Agaricus, Lichens etc.
Yeast

Angiosperms.
v) Animalia (Animals) :-
They include all organisms which are multicellular,
eukaryotes, without chlorophyll and cell walls. They are
heterotrophs.
They are divided into ten groups. They are :-
Porifera, Coelenterata, Platyhelminthes, Nematoda,
Annelida, Arthropoda, Mollusca, Echinodermata,
Protochordata, and Vertebrata.
11. 5) Classification of plants (Plantae) :-

13. iii) Pteridophyta :-
In this group the plant body is differentiated into roots, stem and
leaves and has vascular tissue for conducting water and other
substances from one part of the plant body to the other. Eg :- Ferns,
Marsilea etc.

14. iv) Gymnosperms (Cryptogams) :-
The plants of this group bear naked seeds (gymno – means naked
and sperma means seed). They are usually perinneal, evergreen and
woody.
Eg :- Pines (Pinus), Cycas etc.
Pines Cycas
15. v) Angiosperms (Phanerogams) :-
The plants of this group bears covered seeds (angio –
means covered and sperma – means seed). They are also
called flowering plants. The plant embryo in the seed have
cotyledons.
Angiosperms are divided into two groups on the basis of
the number of cotyledons. Plants with seeds having single
cotyledon are called monocots. Eg :- rice, wheat, maize etc.
green gram, peas, tamarind etc. Plants with seeds having
two cotyledons are called dicots. Eg :- green gram, peas,
tamarind etc.

young ones. Some of them lay eggs (like Platypus and
Echidna).
Eg :- Cat, Rat, Dog, Lion, Tiger, Whale, Bat, Humans etc.
32. 7) Nomenclature :-
All living organisms have been given scientific names
which can be used to identify them anywhere in the world.
The system of scientific naming organisms is called
binomial nomenclature. The binomial nomenclature
consists of two parts. The first part is the name of the
genus and the second part is the name of the species.
The system of scientific naming or nomenclature we use
today was introduced by Carolus Linnaeus.
Eg :- The scientific name of human beings is – Homo
sapiens. Homo is the name of the genus and sapiens is the
name of the species.
