Learn About Cells Today


The cells of protozoa, higher plants and animals are highly structured. These cells tend to be larger than the cells of bacteria, and have developed specialized packaging and transport mechanisms that may be necessary to support their larger size. Use the Interactive animation of plant and animal cells to learn about their respective organelles.

About Plant Cells

Plant cells are similar to animal cells in that they are both eukaryotic cells and have similar organelles. Plant cells are generally larger than animal cells. While animal cells come in various sizes and tend to have irregular shapes, plant cells are more similar in size and are typically rectangular or cube shaped. A plant cell also contains structures not found in an animal cell. Some of these include a cell wall , a large vacuole, and plastids. Plastids, such as chloroplasts , assist in storing and harvesting needed substances for the plant. Animal cells also contain structures such as centrioles , lysosomes , and cilia and flagella that are not typically found in plant cells.
