The document discusses two phyla: Porifera, known as sponges, which are multicellular aquatic animals with pores and no organs that live in sea and fresh water. Their green color comes from algae living in their bodies in a mutualistic relationship. Coelenterata, known as coelenterates, which have a cavity called a coelenteron and two cell layers. They are mostly marine animals like hydra, jellyfish, and sea anemones, with some living in fresh water.

Protists are unicellular eukaryotic organisms that can be categorized into three main groups: animal-like protists, plant-like protists, and fungus-like protists. They were some of the first organisms on Earth and include microbes that can cause disease. While similar to bacteria in being microscopic and unicellular, protists differ in having a nucleus and generally living as individual eukaryotic cells. Plant-like protists, or algae, can be autotrophs that produce oxygen through photosynthesis. Fungus-like protists have cell walls and reproduce using spores.

Protists are unicellular eukaryotic organisms that can be categorized into three main groups: animal-like protists, plant-like protists, and fungus-like protists. They were some of the first organisms on Earth and include microbes that can cause disease or act as parasites. While similar to bacteria in being microscopic and unicellular, protists differ in possessing a nucleus and generally living as individual eukaryotic cells. Examples of protists include amoebas, paramecium, algae, and water molds.

The document provides information about different types of protozoa including their structures and characteristics. It discusses the structures of three protozoa - Amoeba, Euglena, and Paramecium. Amoeba is a unicellular, freshwater organism that feeds through intracellular digestion and absorbs food through its general body surface and pseudopods. Euglena is a single-celled flagellated microorganism that has characteristics of both plants and animals, containing chloroplasts. Paramecium is a free-living, ciliated protozoan commonly found in stagnant freshwater with a slipper-shaped body surrounded by a pellicle.

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.

- 1. Phylum Porifera 1. This phylum is called porifera because animals belonging to this phylum have numerous small pores on their bodies. 2. They are also called sponges. 3. They are multicellular but they have no organs or true tissues. 4. Every cell performs its all function. 5. Sponges are aquatic animals. Most of them are found in sea water but some live in fresh water. 6. Sponges have different colours. 7. Green colour of sponge is due to algae that live in their body. Algae produce oxygen during photosynthesis which is used by sponges and the sponges release carbondioxide, which is used by algae for photosynthesis. This association in which both the organisms benefit from each other is called mutualism.
- 8. Phylum coelenteron 1. Animals belonging to this phylum have a special cavity in their body which is called coelenteron and due to this reason they are called coelenterates. 2. They are diploblastic animals as their bodies have two layers of cells. Outer layer is called ectoderm and inner layer is called endoderm. Between these layers a jelly like substance the mesoglea is present. 3. Coelentrates are aquatic animals. They are mostly marine but few live in fresh water. 4. Most of the animals of this phylum can move freely but a few remain attached to stones or rocks throughout their life. 5. Hydra, Jellyfish and Sea anemone are common examples of this phylum.
