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
