Question

animal cells do not contain which of the following organelles?
chloroplasts
lysosomes
nucleus
cell membrane

Explanation:

To determine which organelle animal cells lack, we analyze each option:

• Chloroplasts: These are involved in photosynthesis and are found in plant cells (and some protists), not animal cells.
• Lysosomes: Present in animal cells for digestion/breakdown.
• Nucleus: Contains genetic material and is present in animal cells.
• Cell Membrane: Encloses animal cells (plants have a cell wall + membrane).

Thus, chloroplasts are absent in animal cells.

Answer:

A. Chloroplasts
