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.

Ribosomes
• Makes Proteins• Float around in the cytoplasm and can be
attached to the ER

Endoplasmic Reticulum
• Makes and modifies lipids/fats• Breaks down drugs• Packages proteins and sends them to the golgi
apparatus

Mitochondria
• Breaks down food (sugar/glucose/C6H12O6) into ENERGY (ATP) that cells can use
• Cellular Respiration

Chloroplast
• Uses sunlight to create Sugar (Glucose/C6H12O6/food)
• Found Only in the PLANT CELL

Golgi Apparatus
• Packages and Transports materials out of the cell

Large Central Vacuole
• Stores water and other materials

What do Lysosomes do?
no picture given, but they are small and spherical in shape
![Page 17: 1.1 Cell Organelles](https://reader036.fdocuments.net/reader036/viewer/2022062411/568167f5550346895ddd6d84/html5/thumbnails/17.jpg)
Lysosomes
• Digest food particles, waste, worn out cell parts, and foreign invaders

Cell Wall
• Rigid structure located outside of the cell membrane of Plant Cells
• Function: Support and Protect the Plant Cell• PLANT CELL ONLY

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

Centrioles
• Helps divide the cell during cell division (mitosis)

Cytoplasm
• Is the liquid substance that fills the inside of the cell.
• All organelles are cushioned and surrounded by cytoplasm
