A typical plant cell is mainly distinguished from an animal cell by the possession of

Step 1: Analyze the question The question asks which features are mainly found in plant cells but not in animal cells.

Step 2: Key concept Plant and animal cells are both eukaryotic, so they share many structures. The differences are:

| Structure | Plant cell | Animal cell | |---|---|---| | Cell wall (cellulose) | Present | Absent | | Chloroplast | Present (in green parts) | Absent | | Large permanent vacuole | Present | Absent or small | | Centrioles | Usually absent | Present | | Nucleus | Present | Present | | Cytoplasm | Present | Present | | Mitochondria | Present | Present |

Step 3: Check each option

• A. Chloroplast and nucleus: Both cell types have a nucleus, so this is wrong.
• B. Cell wall and cytoplasm: Both cell types have cytoplasm, so this is wrong.
• C. Chloroplast and cell wall: Both are found only in plant cells, so this is correct.
• D. Cell wall and mitochondrion: Animal cells also have mitochondria, so this is wrong.

Step 4: Answer The correct option is C, chloroplast and cell wall.

Tip: Remember "plants have a wall and are green." Cell wall and chloroplast are the two unique features. Any structure that both cell types share (nucleus, cytoplasm, mitochondria, cell membrane) can never be the answer to a "distinguishing feature" question.
