How Are Animal Cells Different from Plant Cells

How Are Animal Cells Different from Plant Cells: Cells are the functional and structural units of all living organisms. Both plants and animals have them, but animal cells are different from plant cells in some respects. There are certain characteristics that clearly set them apart, but essentially they are the same and share the same functions. Here are the main differences between them.

Plant Cells

– have chloroplasts containing chlorophylls, meaning light-absorbing pigments that help them in the photosynthesis process, which enables them to make their own food;
– have a cell wall over the cell membrane, which supports a rigid, typically rectangular structure that is composed of cellulose, hemicellulose, and many other materials;
– are more square shaped;
– have a single large, central vacuole that usually takes up 90% of cell volume;
– have plasmodesmata, which are microscopic channels that traverse the cell walls and are considered to be communication pathways;
– do not have centrioles (except for lower plant forms).

Animal Cells

– do not have chloroplasts;
– do not have a cell wall; they only have the cell membrane;
– are either circular or irregular; as they do not have a cell wall, animal cells have more dynamic shapes, but they are mostly circular;
– have one or more vacuoles; even though there are many more vacuoles in the animal cell, they do not take up the volume that the central vacuole in plants does;
– do not have plasmodesmata;
– have centrioles; plants do not need to have these organelles, since their spindle fibers connect to the cell wall.

These are the main differences between plant and animal cells. Except for these particular features, they share the same organelles: endoplasmatic reticulum (smooth and rough), ribosomes, mithochondria, Golgi apparatus, plasma membrane, microtubules and microfilaments, lysosomes, and nucleus. Flagella may be found is some cells, as well as cilia. However, cilia is quite rare in plant cells.
