Question

what are the main differences between plant and animal cells? (4 points) plant cells have smooth endoplasmic reticulum. plant cells are more rigid due to the cell wall. animal cells have rough endoplasmic reticulum. animal cells have a large central vacuole.

Explanation:

Plant cells have a cell - wall which makes them more rigid compared to animal cells. Animal cells do not have a cell - wall. Also, plant cells often have a large central vacuole while animal cells may have small vacuoles or none at all. The presence of chloroplasts in plant cells (for photosynthesis) is another major difference not mentioned in the options. However, among the given options, plant cells are more rigid due to the cell wall.

Answer:

Plant cells are more rigid due to the cell wall.
