Plant and animal cells are both eukaryotic cells that contain organelles and a nucleus. While they share some similarities, like both having a cell membrane, cytoplasm, mitochondria and vacuoles, they also have key differences. Plant cells are typically rectangular in shape with a rigid cell wall, chloroplasts for photosynthesis, and a large central vacuole. In contrast, animal cells are usually spherical or irregular in shape without a cell wall, chloroplasts or rigid cell wall, obtaining nutrients by other means than photosynthesis.

Cytology is the study of cells. Anton van Leeuwenhoek first observed cells using microscopy in the 1600s. Robert Hooke coined the term "cell" after observing plant cells in 1665. The cell theory, developed in the mid-1800s, states that all living things are made of cells, cells are the basic unit of structure and function, and new cells are produced from existing cells. Cells come in two main types - prokaryotes which lack nuclei and organelles, and eukaryotes which have nuclei and organelles. All cells share common structures like the cell membrane, cytoplasm, and in eukaryotes, the nucleus, but they also contain specialized structures called organelles that perform
Organelles in an Animal Cell
Animal cells contain organelles that carry out specific functions. The cell membrane forms the outer boundary and regulates what enters and exits the cell. The cytoplasm holds organelles like the nucleus, which controls cell activities, mitochondria that generate energy, and the endoplasmic reticulum and Golgi complex which transport proteins. Other organelles include vacuoles for storage, lysosomes for waste removal, and ribosomes for protein production. Together these organelles allow the cell to maintain structure, carry out specialized functions, and sustain life.

In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.

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. Plant Cells vs. Animal Cells Similarities and Differences
- 2. Cell Analogy •Cells have a bunch of stuff inside of them that all have a certain role! • https://youtu.be/UmHFV P4Sw8w • https://youtu.be/VnvZE_ ODNjw
- 3. Organelles •Small parts within the cell •Each organelle has a specific, and different job to do in order to keep the cell alive
- 4. Remember… •Prokaryote •Simplest cells •Single-celled •Few, basic organelles •DNA floating around, uncontained •Eukaryote •Complex cells •Single or multi-celled •More organelles •DNA contained within the nucleus
- 7. Eukaryote! • Plant and animals cells are both eukaryote cells as because they are multicellular and contain many organelles within each cell, including a nucleus where the DNA is stored.
- 8. How are they different? •We know plants and animals LOOK different, so how are their CELLS different?
- 9. Shapes of the cells •Plant cells are rectangular or boxy – regularly shaped •Animal cells are round or oval – irregular in shape
- 10. Structure of the cells •Only plant cells have a CELL WALL. •The CELL WALL provides the plant cell with SUPPORT. •Animal cells DO NOT have cell walls because they have skeletons that provide the support. I’m not found in plants!
- 11. Some Parts of the Cells •Chloroplast is ONLY found in PLANT cells. •Chloroplast produces food for the plant cell.
- 12. Certain Organelles •Chloroplast produces food by converting sunlight into sugar by the process called photosynthesis.
- 13. How are they the same? •We know plants and animals are both eukaryote cells, so they also have to have some similarities.
- 14. How are they the same? •Plant and animal cells are both eukaryotic cells.
- 15. Both have Nucleuses •The nucleus is the “brain” or information center of the cell •This is where the DNA hangs out •All eukaryotic cells have nucleus surrounded by nuclear membranes
- 16. Both have Cell Membranes •The cell membrane controls what gets in and out of the cell. •(But remember, the plant cell has a CELL WALL outside of the CELL MEMBRANE.
- 17. Both have Cytoplasm •Cytoplasm is the jelly-like substance within the cell where the organelles are positioned.
- 18. Both have Mitochondria •Mitochondria produce energy for the cells
- 19. Both have Vacuoles…but… •Vacuoles store food and water in both plant and animal cells** •Vacuoles in PLANTS are much LARGER!!! •Why??? •(**Sometimes there more than one vacuoles or no vacuoles in animal cells…)
- 20. To Summarize… Plant Cells Animal Cells Shape – boxy or rectangular, regularly-shaped Shape – circular or round, irregularly-shaped
- 21. To Summarize… Plant Cells Animal Cells Shape – boxy or rectangular, regularly-shaped Shape – circular or round, irregularly-shaped Have a cell wall for support No cell wall (don’t need it because it has a skeleton!)
- 22. To Summarize… Plant Cells Animal Cells Shape – boxy or rectangular, regularly-shaped Shape – circular or round, irregularly-shaped Have a cell wall for support No cell wall (don’t need it because it has a skeleton!) Have chloroplasts to produce food through the process of photosynthesis No chloroplast – obtain food in other ways beside photosynthesis
- 23. To Summarize… Plant Cells Animal Cells Shape – boxy or rectangular, regularly-shaped Shape – circular or round, irregularly-shaped Have a cell wall for support No cell wall (don’t need it because it has a skeleton!) Have chloroplasts to produce food through the process of photosynthesis No chloroplast – obtain food in other ways beside photosynthesis (One) large vacuole Small (one or more) vacuoles (sometimes no vacuole)
