Plant and Animal similarities and differences


Similarities:

Both plant and animal cell have some similar structural elements. Some of the similarities is that both contain eukaryotic, which means they have a nucleus. The nucleus contains chromosomes. The nucleus is protected ans surrounded by the cytoplasm, which is a watery or gel-like liquid. Plant and animal cells also have a cell membrane that surrounds the cell itself. This allows for the cell to have control over what can penetrate the cell and what can't. These are some similarities between a plant and animal cell.

Differences:

Plant cells have a cell wall made up of cellulose. This helps the allow high pressure to built inside of the cell without bursting. A plant cell has to be able to carry large amounts of liquids through osmosis without being destroyed. Plant cells also used photosynthesis to convert sunlight into needed food for the plant. They also have chloroplasts, which has its own DNA.


Animal cells have small vacuoles and may have numerous ones. They never have the large single vacuole that takes up most of the space in plant cells. As well, under the microscope plant cells have a regular shape. An animal cell tends to carry greatly in appearance.
