The document discusses the six kingdoms of life: Archaea, Bacteria, Protista, Fungi, Plantae, and Animalia. It provides details on the distinguishing characteristics of each kingdom, such as Archaea thriving in extreme environments, Bacteria having cell walls made of peptidoglycans or amino sugars, Protista being generally unicellular and eukaryotic, Fungi having cell walls made of chitin and decomposing organic matter, Plantae having cell walls made of cellulose and performing photosynthesis, and Animalia being multicellular and lacking cell walls. The document also compares prokaryotic and eukaryotic cells as well as plant and animal cells

Structure of prokariyotic and eukariyotic cells By KK Sahu SirKAUSHAL SAHU
Introduction
Origin
Prokaryotic cell structure
Eukaryotic cell structure
Comparision of prokaryotes and eukaryotes
Special points
Conclusion
The invention of electron microscope lead to the detailed study of cells.
Based on these studies, cells were classified as prokaryotes (Gr,pro-primitve; karyon-nucleus) and eukaryotes (Gr,eu-true; karyon-nucleus)
This presentation contains the Human Skeletal and Muscular System. Components and Physiological Processes were also discussed. Naming of muscles was highly emphasized.

Observation of Io’s Resurfacing via Plume Deposition Using Ground-based Adapt...Sérgio Sacani
Since volcanic activity was first discovered on Io from Voyager images in 1979, changes
on Io’s surface have been monitored from both spacecraft and ground-based telescopes.
Here, we present the highest spatial resolution images of Io ever obtained from a groundbased telescope. These images, acquired by the SHARK-VIS instrument on the Large
Binocular Telescope, show evidence of a major resurfacing event on Io’s trailing hemisphere. When compared to the most recent spacecraft images, the SHARK-VIS images
show that a plume deposit from a powerful eruption at Pillan Patera has covered part
of the long-lived Pele plume deposit. Although this type of resurfacing event may be common on Io, few have been detected due to the rarity of spacecraft visits and the previously low spatial resolution available from Earth-based telescopes. The SHARK-VIS instrument ushers in a new era of high resolution imaging of Io’s surface using adaptive
optics at visible wavelengths.

Nutraceutical market, scope and growth: Herbal drug technologyLokesh Patil
As consumer awareness of health and wellness rises, the nutraceutical market—which includes goods like functional meals, drinks, and dietary supplements that provide health advantages beyond basic nutrition—is growing significantly. As healthcare expenses rise, the population ages, and people want natural and preventative health solutions more and more, this industry is increasing quickly. Further driving market expansion are product formulation innovations and the use of cutting-edge technology for customized nutrition. With its worldwide reach, the nutraceutical industry is expected to keep growing and provide significant chances for research and investment in a number of categories, including vitamins, minerals, probiotics, and herbal supplements.

Seminar of U.V. Spectroscopy by SAMIR PANDASAMIR PANDA
Spectroscopy is a branch of science dealing the study of interaction of electromagnetic radiation with matter.
Ultraviolet-visible spectroscopy refers to absorption spectroscopy or reflect spectroscopy in the UV-VIS spectral region.
Ultraviolet-visible spectroscopy is an analytical method that can measure the amount of light received by the analyte.

and naming organisms.
Systematics – is the science of
classifying and naming organisms
based on phylogenetic (evolutionary)
relationship and complexity.

- 6 Kingdoms of Life and their distinguishing
characteristics
33. Eubacteria vs. Archaebacteria
Points of
Differences
Archaebacteria Eubacteria
habitat Thriving in extreme types
of environment or harsh
environment like in
undersea volcanic vents,
acidic hot springs, salty
water, methane –rich
environment.
Found in normal
environments like the soil,
water, air, inside or on
plants, animals. Some
other bacteria live
symbiotically in the guts of
animals or elsewhere in
their bodies.

38. Some benefits of Bacteria
Many Eubacteria are also nitrogen fixers like
the Rhizobacteria that converts nitrogen into
usable forms in plants
39. Some benefits of Bacteria
They are also decomposers
that break down complex
organic compounds into
usable inorganic simple
forms. This makes them very
important components of
the ecosystem that make
possible the cycling of many
materials in the
environment.
40. Some benefits of Bacteria
Some eubacteria exhibit mutualistic symbiosis
with animals and man. An example of this is
Lactobacillus which is found in the intestines of
man. These bacteria assist man in the process of
digestion.
Many are used in medicine and industry via
genetic engineering where products like
enzymes, hormones like insulin, vaccines, blood
proteins, antibiotics and more are produced.
41. Some Harmful effects of Bacteria
Some bacteria cause food spoilage
Many cause diseases to man, animals, plants
and fungi. They are considered pathogens.
43. Plants
Eukaryotic and Multicellular
Cell wall composition: Cellulose
and hemicelluloses
Has an organelle chloroplast
which contains pigments such as
chlorophyll that is responsible for
photosynthesis. (Autotroph)

45. Plant vs. Animal Cell
Points of Differences Plant Cell Animal Cell
Cell wall present absent
chloroplast present absent
Centrioles absent present
vacuoles large small
Reserved food starch glycogen
46. Fungi
Saprophytic in nature, they decompose complex
molecule into simple molecule.
Fungal cells do not have chloroplasts thus they
cannot perform photosynthesis
Fungal cell walls are made up of chitin.
Fungal cells do not differentiate thus they do not have
roots, leaves, stems or leaves.
Fungal cells grow at the tips of their hyphae.
Fungal cells produce spores for reproduction
47. Protista (Protist)
Generally, unicellular organisms
Eukaryotic
Many are ciliated or flagellated or
amoeboid
Some are autotrophs and others
are heterotrophs
Some with chloroplasts.
