1.1 Cell Organelles
What is it & What does it do?
Nucleus
• Controls all the activities that go on within the cell
• Contains: DNA / Chromosomes• Contains Nucleolus – which has the directions
for how proteins are to be made a the ribosomes.
What is it & What does it do?
Ribosomes
• Makes Proteins• Float around in the cytoplasm and can be
attached to the ER
What is it & What does it do?
Endoplasmic Reticulum
• Makes and modifies lipids/fats• Breaks down drugs• Packages proteins and sends them to the golgi
apparatus
What is it & What does it do?
Mitochondria
• Breaks down food (sugar/glucose/C6H12O6) into ENERGY (ATP) that cells can use
• Cellular Respiration
What is it & What does it do?
Chloroplast
• Uses sunlight to create Sugar (Glucose/C6H12O6/food)
• Found Only in the PLANT CELL
What is it & What does it do?
Golgi Apparatus
• Packages and Transports materials out of the cell
What is it & What does it do?
Large Central Vacuole
• Stores water and other materials
What do Lysosomes do?
no picture given, but they are small and spherical in shape
Lysosomes
• Digest food particles, waste, worn out cell parts, and foreign invaders
What is it & What does it do?
Cell Wall
• Rigid structure located outside of the cell membrane of Plant Cells
• Function: Support and Protect the Plant Cell• PLANT CELL ONLY
What is it & What does it do?
Cell Membrane
• Thin covering that surrounds all cells • It controls what enters and exits the cell• Barrier• It is Semi-Permeable –meaning it allows some
things in and other not
What is it & What does it do?
Centrioles
• Helps divide the cell during cell division (mitosis)
What is it Cytoplasm & What does it do?
Cytoplasm
• Is the liquid substance that fills the inside of the cell.
• All organelles are cushioned and surrounded by cytoplasm
