kodGreya [7K]

The difference between animal and plant cells is that they contain different organelles, among these are the chloroplasts that plant cells contain and animal cells do not.

<h3>What are the differences between animal and plant cells?</h3>

Each of these cells will have their own requirements, which is why they will have different types of organelles to be able to meet these requirements. Among the differences will be that plant cells will have chloroplasts to be able to generate their own food since they cannot obtain it by other means, so they will manufacture sugar through sunlight.

In plant cells it will have a cell wall that will be surrounded by a cell membrane. While animal cells will not have this cell wall.

Therefore, we can confirm that plant cells and animal cells will have differences in their content, function and organelles.
