What are two similarities of plant and animal cells?

Answer 1

• Except for RBCs, both animal and plant cells have a nucleus.
• Both have the same organelles, floating in the cytoplasm i.e. the organelles are the mitochondria, Golgi body, ribosmomes, and the endoplasmic reticulum.

This answer compares and contrasts the features of a plant cell and an animal cell.

A plant cell has a vacuole. This is a sac in which the cell stores water and nutrients. An animal cell has no vacuole as it does not make its own food and therefore does not need to store these nutrients in that way.

A plant cell has chloroplasts. These are the instruments in which photosynthesis occurs (the process of plants making their own food), and where the pigment chlorophyll comes from, which makes the plant green. An animal cell has no chloroplasts as it does not need to make its own food.

Both plant and animal cells have a nucleus. The nucleus controls the function of the cell and what takes place in it. All cells need this control.

Both plant and animal cells have a cytoplasm. The cytoplasm is what fills up the cell and gives it shape. Many important metabolic reactions take place in the cytoplasm. All cells need these reactions to occur.

The animal cell has a cell membrane and the plant cell has a cell wall. Both perform the same main function - they are a semipermeable membrane that controls the entry and exit of gases and substances to and from the cell.

The cell wall, however, is more rigid and thick, while the cell membrane is more flexible and is thinner. The animal cell membrane is thin and flexible because the animal gets its strength from the skeleton structure of the animal. However, the plant does not have a bone structure, so its strength must come from the cellular level. The thick and rigid cell wall provides this strength.

Answer 2

They both have a nucleus (which controls the cell) and a cell surface membrane.
