12/20ORGANELLES
4

• Even if cells are very tiny, they are made up of
  smaller parts, and the parts do different jobs.

These tiny parts are called organelles
5

• Organelles- small structures in cytoplasm that
  help cells function properly

6
Write these in your notebook leave enough room
to write a definition

• Mitochondria-
• Endoplasmic Reticulum-
• Lysosome-
• Golgi Apparatus-
• Ribosome
• Microtubules/Microfilaments-
• Cilia/Flagella
• Vacuole-

7

• Mitochondria- stores and releases energy for the
  cell
• Powerhouse of the Cell

8

• What type of cell in our body do you think would
  have more then 1 mitochondria because it needs
  more energy?

Muscle cells
9

• Endoplasmic Reticulum- network of membranes that
  helps with movement

1)Smooth Endoplasmic Reticulum
2) Rough Endoplasmic Reticulum (has ribosomes)
10
Lysosome
- Removes worn out cell parts
- (responsible for tadpoles losing tails)
Golgi Apparatus
- Packaging area for proteins
Ribosome-
- Packaged proteins
11
Microtubules/microfilaments-

• Tiny tubes
• Cell skeleton that give cell shape

12

• Cilia/Flagella-

Help cell move/bring food to cell
Cells will have 1 or other but never both
Can you name one cell in the human body that has
a flagella?
13

• Vacuoles-

Store food or water
Storage tanks
