• A. Centriole can be found in animals but not in many plants
• B. Both animal cells and plant cells are green
• C. Cell membranes are present in plant cells but absent in animal cells
• D. Both animal and plant cells have chloroplast

Answer 1

The correct option is A

Centriole can be found in animals but not in many plants

The correct option is A.

The explanation for the correct option:

1. In animal cells and some lower plant cells, the centrosome is positioned near the nucleus. However, it is not found in the higher plants.
2. Centrioles are found in and are a part of the centrosome in animal cells, where they feature two structures that are at right angles to one another.

The explanation for the incorrect options:

Option B:

Plant cells are green, but animal cells are not necessarily green.

Option C:

1. The cell membrane is surrounded by the cell wall in plants.
2. A cell membrane exists in animal cells, but there is no cell wall.

Option D:

1. Plant cells have chloroplast, while animal cells do not.
2. The chloroplast's job is to produce sugar that fuels the machinery of the plant cells.

Final answer: “Centriole can be found in animals but not in many plants." is the only true statement among the given options.
