PARTS OF THE PLANT CELL

PLANT CELL

Plant cells are eukyrotic cells (cells with a clearly defined nucleus) and they change and divide as the plant develops. In their interior, a fundamental process takes place: photosynthesis. The way in which a plant cell receives nutrients is called autotrophy.

start

nucleus

Function

• This is where the genetic information or DNA (deoxyribonucleic acid) is stored, which is responsible for processes like metabolism and growth and development.

Composition

• It is an organelle which is surrounded by a dual structure called the nuclear envelope.

smooth endoplasmic reticulum

Function

• It is mainly responsible for the production of lipids.

Vacuole

Function

• It is responsible for maintaining the shape and size of the cell, as well as storing substances.

Composition

• They are very large vesicles that can occupy 90% of the cell volume, displacing all organelles to the other side of the cell.

Characteristics

• It is surrounded by a vacuolar membrane.

Chloroplasts

Function

• They are the organelles responsible for the production of energy in the cell. They produce chlorophyll, which is responsible for absorbing light for photosynthesis.

golgi apparatus

Function

• Responsible for the synthesis and secretion of complex polysaccharides and has a very important role in the formation of the cellular wall.

mitochondria

Function

• Responsible for obtaining the energy needed by the cell through cellular respiration.

Composition

• They are large organelles, wrapped by a double membrane: one inner and one outer. The inner membrane has a folded structure called cristae and the outer membrane is smooth.

LYSOSOMES

Function

• They contain digestive enzymes with which they perform cellular digestion.

cellular wall

Function

• A rigid structure which protects the cells and gives them their shape.

Composition

• It is the rigid outer cover that is mainly made up of cellulose.

Characteristics

• It is located on the outside of the plasma membrane.
