Question

What similarities and differences are there between the animal cell, the plant cell, and the green algae cells?

A. All three cells have a nucleus and chloroplasts, but only animal cells have cell walls.
B. Animal and plant cells have cell walls, while green algae cells do not.
C. Animal cells have a nucleus, but plant and green algae cells do not.
D. All three cells have a nucleus and chloroplasts, but animal cells lack cell walls.

Answer 1

Animal, plant, and green algae cells all have a nucleus and cytoplasm, but only plant cells and some algae have chloroplasts and a cell wall. Animal cells contain lysosomes and centrioles, which are absent in plant cells. Plant cells have plastids and a large vacuole, unlike animal cells.

Step-by-step explanation:

The similarities and differences between animal cells, plant cells, and green algae cells are significant in understanding eukaryotic cell diversity. One common feature is that all three types of cells possess a nucleus and cytoplasm. However, there are notable differences, particularly between animal and plant cells. Animal cells lack cell walls and chloroplasts, which are characteristic features of plant cells. Additionally, animal cells contain centrioles, centrosomes, and lysosomes, which are not found in plant cells.

Plant cells, on the other hand, have a rigid cell wall made of cellulose, chloroplasts for photosynthesis, plastids for storage, and a large central vacuole, which are all absent in animal cells. As for green algae, they share some plant cell characteristics, such as having chloroplasts and potentially a cell wall, depending on the type of algae.
