Plant cells are not necessarily square, but they due tend to have distinct edges and be somewhat rectangular. This structure is caused by the cell wall which is very rigid and therefore forces the cell to have a defined shape. They are not necessarily round but instead have an irregular shape.

Rigid cell walls give the plant cells their regular shape. Cell walls are designed to resist water pressure in the plant call. Plant cell walls contain cellulose, a structural carbohydrate. Rigid cell walls give the plant cells their regular shape.

Answer. Animal cells are round and irregular in shape while plant cells have fixed, rectangular shapes. Plant cells have a cell wall which provides structural integrity to the cell. Due to the presence of cell wall, they are rectangular in shape.

Animal cells and plant cells share the common components of a nucleus, cytoplasm, mitochondria and a cell membrane. Plant cells have three extra components, a vacuole, chloroplast and a cell wall.

A plant cell is surrounded by rigid cell wall whereas animal cell does not have cell wall. Presence of a large vacuole in plant cell, which is small in animal cell. Plant cells have plastids whereas animal cells do not have plastids. Centrosomes are absent in plant cell whereas animal cell have centrosomes.

Plant Cell Functions Plant cells are the building blocks of plants. Photosynthesis is the major function performed by plant cells. Photosynthesis occurs in the chloroplasts of the plant cell. It is the process of preparing food by the plants, by utilizing sunlight, carbon dioxide and water.

The vital parts of a cell are called “organelles.” Among the most important are the nucleus, vacuoles, and mitochondria, all of which are enclosed within the cell membrane and immersed in cytoplasm. Each organelle performs a specific task that helps keep the cell alive.

The mitochondrion (plural mitochondria) is a membrane-bound organelle found in the cytoplasm of eukaryotic cells. It is the power house of the cell; it is responsible for cellular respiration and production of (most) ATP in the cell.

: any of various round or long cellular organelles of most eukaryotes that are found outside the nucleus, produce energy for the cell through cellular respiration, and are rich in fats, proteins, and enzymes — see cell illustration.

Known as the “powerhouses of the cell,” mitochondria produce the energy necessary for the cell’s survival and functioning. Through a series of chemical reactions, mitochondria break down glucose into an energy molecule known as adenosine triphosphate (ATP), which is used to fuel various other cellular processes.

Description. Mitochondria are structures within cells that convert the energy from food into a form that cells can use. Each cell contains hundreds to thousands of mitochondria, which are located in the fluid that surrounds the nucleus (the cytoplasm).

Cytoplasm is contained within cells in the space between the cell membrane and the nuclear membrane.

Because of this double-membraned organization, there are five distinct parts to a mitochondrion:

• The outer mitochondrial membrane,
• The intermembrane space (the space between the outer and inner membranes),
• The inner mitochondrial membrane,
• The cristae space (formed by infoldings of the inner membrane), and.

What is the important function of cytoplasm? The cytoplasm is responsible for holding the components of the cell and protects them from damage. It stores the molecules required for cellular processes and is also responsible for giving the cell its shape.
