Animal and Plant Cell Differences

Cell Structure

Lysosomes: Specialized Organelles for Animal Cells

Animal cells are equipped with specialized organelles known as lysosomes. These are essentially compartments within the cell that contain an extremely acid environment. Lysosomes play a crucial role in digesting cellular waste, destroying damaged organelles, and recycling materials within the cell.

Chloroplasts: Exclusive to Plant Cells

Plant cells, on the other hand, possess chloroplasts—the organelles responsible for photosynthesis. These cellular structures contain chlorophyll, the green pigment that absorbs sunlight and converts it into chemical energy. Chloroplasts are essential for plants to synthesize their own food from inorganic compounds.

Cell Size and Number

Cell Size Variations

Animal cells are generally smaller than plant cells. This difference is attributed to the presence of a cell wall in plant cells, which provides additional rigidity and support. The size of cells within a species, however, can also vary significantly depending on their function.

Cell Number Variations

The number of cells in plants and animals varies vastly between species. For instance, the human body is composed of trillions of cells, while a fern may have only a few thousand cells. These differences are primarily related to the complexity and size of the organism.
