Question

Which statement best describes models A and B above? (DOK 2)

a) Model A is an animal cell and model B is a plant cell because model B contains chloroplasts and a cell wall, all of which model A does not have.

b) Model A is an animal cell and model B is a plant cell because model A contains a nucleus in the center of the cell and model B contains a nucleus near the edge.

c) Models A and B are both plant cells because they both contain a nucleus, mitochondria.

d) Models A and B are both animal cells because they both contain a nucleus and mitochondria.

Answer 1

Model A is an animal cell and model B is a plant cell; the presence of chloroplasts and a cell wall in model B distinguishes it as a plant cell.

Step-by-step explanation:

The statement that best describes models A and B is that model A is an animal cell and model B is a plant cell because model B contains chloroplasts and a cell wall, both of which model A does not have. Animal cells and plant cells both have a nucleus, mitochondria, and cytoplasm, but plant cells have additional structures that animal cells lack. Plant cells have a rigid cell wall that provides structure and supports the plant, chloroplasts which are essential for photosynthesis to convert solar energy into chemical energy, and a large central vacuole for storage and maintaining cell shape. Animal cells, on the other hand, do not have these features.
