Some components of cells are listed.
- cell membrane
- cell wall
- chloroplasts
- cytoplasm
Which cell components are present in plant cells but absent in animal cells?
A) 1 and 2
B) 1 and 4
C) 2 and 3
D) 3 and 4
▶️ Answer/Explanation
Ans: C
Plant cells have both a cell wall (2) and chloroplasts (3), which are absent in animal cells. The cell membrane (1) and cytoplasm (4) are present in both cell types.
Since the question asks for components exclusive to plant cells, the correct combination is 2 and 3, making C the right answer.
The diagram shows a plant cell. In which labelled part of the cell is glucose made?
▶️ Answer/Explanation
Ans: B
Glucose is synthesized during photosynthesis, which occurs in the chloroplasts (labelled B). Chloroplasts contain chlorophyll, the pigment that captures sunlight to convert carbon dioxide and water into glucose and oxygen.
Other parts of the cell, such as the nucleus (A), mitochondria (C), or vacuole (D), do not participate in glucose production. Thus, the correct answer is B (Chloroplast).
