To determine the correct conclusion about the cells based on the provided observations, we need to analyze the characteristics of each cell:
-
Cell A:
- Shape: Rectangular
- Observed Organelles: Plasma membrane, cell wall, nucleus, central vacuole
-
Cell B:
- Shape: Round
- Observed Organelles: Plasma membrane, nucleus
In biology, we know that:
- Plant cells typically have a cell wall, a central vacuole, and are usually more rectangular in shape.
- Animal cells do not have a cell wall or central vacuole, and are often more rounded.
Based on the above characteristics:
- Cell A has a cell wall and a central vacuole, indicating that it is likely a plant cell.
- Cell B does not have a cell wall and lacks a central vacuole, suggesting that it is an animal cell.
Given this analysis, the correct conclusion is:
Cell A is a plant cell, and Cell B is an animal cell.
