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
