Cell Theory

• All Living things are made of cells
• All cells come from other living cells of the
  same kind
• Cells are the basic unit of all living things

3
What is a cell?

• Unit of all organisms

4
What are basic cell structure?

• The cell membrane is the thin flexible boundary
  surrounding the cell.
• Cytoplasm is the watery, jellylike part of the
  cell that contains salts.
• Nucleus is the area of the cell where
  DNA(deoxyribonucleic) is located.

5
Prokaryotic Cell

• Prokaryotic cell does not have a true nucleus.

6
Eukaryotic Cell

• Eukaryotic cell has a nucleus surrounded by a
  nuclear membrane.

7
DNA

• DNA is a complex molecule with a double helix
  shape
• There are 4 basic bases - Adenine,
  Thymine,Guanine,and Cytosine.
• A and T go together, C and G go together

8
Mitochondria

• Mitochondria are rod-shaped double membranous
  structures where cellular respiration takes place
  
• A lot people called the Mitochondria the power
  house it helps people remember the mitochondria.

9
Cell Membrane and Cytoplasm

• Cell Membrane is the membrane surrounding the
  cell that allows some molecules to pass through

• Cytoplasm is a jelly-like substance in cell
  around nucleus and organelles

10
Endoplasmic Reticulum

• Endoplasmic Reticulum (ER) are folded membranes
  having areas with and without ribosomes used for
  transport of RNA and proteins.
• Smooth ER dont have ribosomes
• Rough ER have ribosomes

11
Ribosomes

• Ribosomes are structures that manufacture
  proteins found on ER and floating in the
  cytoplasm

12
Different between Animal and Plant cell

• Some Animal Cells have cilia or flagella.

• A Plant Cell has a cell wall and chloroplasts.
