identify the organelles and then explain why they are required in a plant cell but not an animal cell
Some of the organelles found in a plant cell that are not present in an animal cell are:
1. Chloroplasts: Chloroplasts are responsible for carrying out photosynthesis, a process that converts sunlight into usable energy for the plant. This organelle is required in a plant cell because plants make their own food through photosynthesis, whereas animals rely on other organisms for energy.
2. Central vacuole: The central vacuole in plant cells helps maintain turgor pressure, store water and nutrients, and regulate cell size and growth. This organelle is essential for plants, as they need to store a large amount of water and nutrients to support their growth and development.
Additionally, plant cells also contain cell walls, which are composed of cellulose and provide structural support and protection to the cell. Animal cells lack cell walls and rely on other methods, such as the extracellular matrix, for support.
These organelles are required in plant cells but not in animal cells because plants have unique adaptations, such as photosynthesis and the ability to store large amounts of water and nutrients, that require specialized structures to carry out these functions. Animals, on the other hand, have different evolutionary adaptations and do not require these specific organelles for survival.
