TRANSCRIPT
The Cell Theory
• All known living things are made up of cells.
• The cell is structural & functional unit of all living things.
• All cells come from pre-existing cells by division.

CELL MEMBRANE
holds the cell together
keeps all of the pieces (like the organelles and the cytoplasm) inside the cell
controls what goes in and out of the cellExample: like a big plastic bag with tiny holes
in it
5
CYTOPLASM
Cytoplasm - gel-like substance inside the cell that all of the organelles float around in.
7
Mitochondria
Mito = Mighty / Power
The Power-House of the cell
They break down food molecules so the cell has the energy to live
If a cell needs a lot of energy…it will have more mitochondria
8
Endoplasmic Reticulum also known as the
“ER”
a maze of membranes that transports materials inside of the cell
There are two different Smooth ERRough ER
9
GOLGI APPARATUS• Also called the Golgi Complex or Golgi body
• Combines simple molecules into larger molecules
• Packages molecules for transport in the cytoplasm
10
• they are the site of protein synthesis in cells
• they are made in the nucleus of the cell
• A ribosome can make the average protein in about one minute
• There are two types – 1) attached to ER and 2) free floating
Ribosomes
11
LYSOSOMES
• They digest food taken in by the cell
• They break down damaged or worn-out organelles
• Destroy the cell if it accidentally breaks open – “suicide sacs”
12
Cell Wall
• Layer around the outside of the cell membrane of plant cells that provides the cell with extra support and protection.
13
VACUOLE• Storage of water, waste or food….like a
backpack
14
- the site of photosynthesis in eukaryotic cells
- where sunlight energy is converted into chemical energy
