Cell Organelles and Functions

Cell Organelles and Functions Cell Membrane

• protects the cell; performs active transport and passive transport to move materials in and out

Cell Organelles and Functions Cytoplasm

• Jelly like material constantly moving, pads and supports the organelles in the cell

Cell Organelles and Functions Cytoskeleton

• Microtubules and microfilaments together allow the cell to hold its shape, and move itself and its organelles.

Cell Organelles and Functions Mitochondria

• Produces energy for the cell.

• The process of creating cell energy is known as cellular respiration.

Cell Organelles and Functions Ribosomes

• Protein Synthesis

• Makes protein

Cell Organelles and Functions Endoplasmic Reticulum - Abbrev: ER

Two types

• – Smooth (no ribosomes) – produces lipids

• – Rough (covered with ribosomes) - Transports materials throughout the cell

Cell Organelles and Functions Nucleus

• controls the cell’s activities

Cell Organelles and Functions Chromosomes

• They carry the genetic code that determines the characteristic of the organism

• provides the instructions for the cell’s activities (directs growth, reproduction)

Cell Organelles and Functions Centriole

• Found only in animal cells, and are there to help the cell when it comes time to divide.

Cell Organelles and Functions Lysosome

• Vesicles that are there to digest things. They might be used to digest food or break down the cell when it dies.

Cell Organelles and Functions Golgi bodies/apparatus/complex

• Gathers simple molecules and combines them to make molecules that are more complex. It then takes those big molecules, packages them.

• Processes and packages molecules

Cell Organelles and Functions Vacuole

• Plant cell vacuoles

• Very few and very large

• Stores water

• Animal cell vacuoles

• storage-tanks for food, water, wastes, or enzymes

ANIMAL PLANT VACUOLE

Cell Organelles and Functions Cell Wall

• rigid, tough, made of cellulose

• protects and supports each cell

Cell Organelles and Functions Chloroplasts

• captures the energy in sunlight and uses it to produce food
