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.

Composition

• The shape of this organelle varies depending on the cell in which it is found, but it is usually round.

Quantity

• Normally, eukaryotic cells have only one nucleus.

Function

• Holds the cell's DNA
• Processing and managing cell information.

nucleus

Function

• Responsible for the production of lipids, or fats, and breaks down any harmful substances.
• Can change shape to help with different jobs

smooth endoplasmic reticulum

Characteristics

• membrane-bound sac
• Plants have 1 large one, animals have several small ones

Composition

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

Vacuole

Function

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

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.
• Plants contain dozens animals do not have any

Chloroplasts

Composition

• flat, pancake-like sacs stacked on top of each other
• AKA Golgi apparatus or Golgi complex

Function

• Help package proteins and fats from the endoplasmic reticulum
• modifies, sorts, and packages the materials into vesicles and sends them to their location

golgi apparatus

Function

• tiny power plants
• create energy that the cell can use
• take energy from food and change it to energy - cellular respiration

Composition

• They have an elongated shape and have two membranes: an internal membrane that folds into ridges and a smooth external membrane.

mitochondria

Function

• Contains digestive enzymes with which to perform cellular digestion.
• Act like recycling bins
• Digest food, break down old or worn-out organelles, and remove waste.
• defend cells from bacteria

LYSOSOMES

Characteristics

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

Composition

• Thick and rigid

cell wall

Function

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