What is the structure and function of a plant cell?
What is the structure and function of a plant cell?
Plant cells have certain distinguishing features, including chloroplasts, cell walls, and intracellular vacuoles. Photosynthesis takes place in chloroplasts; cell walls allow plants to have strong, upright structures; and vacuoles help regulate how cells handle water and storage of other molecules.
What is the difference between structure and function in plant and animal cell organelles?
Chloroplasts. Plants are autotrophs; they produce energy from sunlight through the process of photosynthesis, for which they use cell organelles called chloroplasts. Animal cells do not have chloroplasts. In animal cells, energy is produced from food (glucose) via the process of cellular respiration.
What are the functions of plant cell?
Plant Cell Functions Plant cells are the building blocks of plants. Photosynthesis is the major function performed by plant cells. Photosynthesis occurs in the chloroplasts of the plant cell. It is the process of preparing food by the plants, by utilising sunlight, carbon dioxide and water.
What is animal cell and its function?
Animal cells are the basic structural and functional units of animal tissues and organs. They are eukaryotic cells. It means that, unlike prokaryotic cells, animal cells have membrane-bound organelles suspended in the cytoplasm enveloped by a plasma membrane.
What is the structure of an animal cell?
The basic structure of a generalized animal cell certainly comprises of the plasma membrane, cytoplasm, nucleus, mitochondria and ribosomes.
What is the difference between plant cell and animal cell?
Plant cells have a cell wall and plastids that animal cells lack.
What is difference between plant cell and animal cell?
Plant cells have a cell wall, but animals cells do not. Cell walls provide support and give shape to plants. Plant cells have chloroplasts, but animal cells do not. Chloroplasts enable plants to perform photosynthesis to make food.
What is structure of animal cell?
Animal cells are typical of the eukaryotic cell, enclosed by a plasma membrane and containing a membrane-bound nucleus and organelles. Unlike the eukaryotic cells of plants and fungi, animal cells do not have a cell wall.
How are plant and animal cells structured?
Plant cells have a cell wall, as well as a cell membrane. In plants, the cell wall surrounds the cell membrane. This gives the plant cell its unique rectangular shape. Animal cells simply have a cell membrane, but no cell wall.
What are the functions of animals?
There are 7 essential functions of animals:
- Feeding: Herbivore = eats plants.
- Respiration: Take in O2 and give off CO2.
- Circulation: Very small animals rely on diffusion.
- Excretion: Primary waste product is ammonia.
- Response: Receptor cells = sound, light, external stimuli.
- Movement:
- Reproduction:
