A cell is the smallest unit of life, responsible for all vital processes like breathing, digestion, growth and reproduction. It is often called the building block of life. All living organisms—plants, animals and microbes—are made up of one or more cells. Some organisms are unicellular, while complex organisms have millions of specialized cells working together to perform different functions.

Onion and cheek cells share features like a nucleus, cytoplasm and cell membrane. However, onion cells (plant cells) also have a rigid cell wall and sometimes chloroplasts, making them rectangular. Cheek cells (animal cells) do not have a cell wall and are irregular in shape. These differences helpRead more
Onion and cheek cells share features like a nucleus, cytoplasm and cell membrane. However, onion cells (plant cells) also have a rigid cell wall and sometimes chloroplasts, making them rectangular. Cheek cells (animal cells) do not have a cell wall and are irregular in shape. These differences help in identifying whether the cell is from a plant or an animal.
