Class 11 Plant cell and animal cell- Certainly! Plant cells and animal cells are the basic structural and functional units of living organisms. Here are some key differences between plant and animal cells:
Plant Cells:
- Cell Wall: Plant cells have a rigid cell wall composed of cellulose outside the cell membrane. The cell wall provides structural support and protection.
- Chloroplasts: Plant cells contain chloroplasts, which are responsible for photosynthesis. Chloroplasts contain chlorophyll, a green pigment that captures sunlight and converts it into energy.
- Large Central Vacuole: Plant cells typically have a large central vacuole that stores water, nutrients, and waste products. It plays a crucial role in maintaining cell turgor pressure.
- Shape: Plant cells often have a fixed rectangular or square shape due to the presence of the cell wall.
- Plastids: Besides chloroplasts, plant cells may contain other plastids, which are responsible for various functions such as the synthesis and storage of pigments, starch, and lipids.
- No Centrioles: Plant cells lack centrioles, which are present in animal cells and are involved in cell division.
Animal Cells:
- No Cell Wall: Animal cells do not have a cell wall. Instead, they have a flexible cell membrane that surrounds the cell and gives it shape.
- No Chloroplasts: Animal cells lack chloroplasts and are unable to perform photosynthesis.
- Small Vacuoles: Animal cells may have small, temporary vacuoles, but they are not as prominent as the central vacuole in plant cells.
- Shape: Animal cells can have various shapes, ranging from round to irregular, and their shape is often determined by the cytoskeleton.
- Centrioles: Animal cells contain centrioles, which are involved in organizing microtubules during cell division (except in higher plant cells).
- Lysosomes: Animal cells typically contain lysosomes, membrane-bound organelles containing digestive enzymes for breaking down waste materials and cellular debris.
It’s important to note that despite these differences, both plant and animal cells share some common features, such as having a nucleus, endoplasmic reticulum, Golgi apparatus, mitochondria, and other cellular organelles. These structures contribute to the basic functions required for the survival and functioning of the cell.
