Question

List three organelles found in PLANT cells, but absent from animal cells.

Explain why animal cells do NOT need the organelles that are found in plant cells, but abdent in animal cells.

Answer 1

Three organelles found in plant cells but absent from animal cells are:

1. Chloroplasts: Chloroplasts are the organelles that are responsible for photosynthesis, the process by which plants produce their own food through the conversion of light energy into chemical energy.
2. Cell walls: Plant cells have a rigid cell wall that provides structure and support to the cell. This cell wall also helps to protect the cell from damage and maintain its shape.
3. Vacuoles: Vacuoles are large, fluid-filled organelles that serve as storage spaces for food, water, and other materials. Plant cells often have one large central vacuole that can occupy up to 90% of the cell's volume.

Animal cells do not need these organelles because they obtain their food through ingestion, rather than photosynthesis. They do not have a rigid cell wall and rely on the plasma membrane for support and protection. Additionally, animal cells have smaller, membrane-bound vesicles for storage, rather than the large central vacuoles found in plant cells.
