serious [3.7K]

animal cell works differently than plant cell

animal cell have million of cell as well plant..

animal cell have four key part ..plant cell have cell wall,chloroplasts, vacuoles

Explanation:

Plant cells have a cell wall, but animals cells do not. Cell walls provide support and give shape to plants.

Plant cells have chloroplasts, but animal cells do not. Chloroplasts enable plants to perform photosynthesis to make food.

Plant cells usually have one or more large vacuole(s), while animal cells have smaller vacuoles, if any are present. Large vacuoles help provide shape and allow the plant to store water and food for future use. The storage function plays a lesser role in animal cells, therefore the vacuoles are smaller.
