The Cell

1
The Cell

• Structure and Function

2
Maintaining a Healthy Cell

• In order to stay healthy and active a cell
  must - obtain food and energy
• - convert the energy to a usable form - make
  and regulate organelles - carry out chemical
  reactions - eliminate waste
• - reproduce
• - keep a record of how to build cell components

3
Cell Types

• Prokaryotes the smallest type of cells with
  simple structure. - They have NO nucleus (an
  enclosed central region within a cell that
  contains DNA/RNA). Their genetic information is
  spread throughout the cell.

4
Cell Types

• Eukaryotes - larger cells with complex
  structures. - all plant and animal cells are
  eukaryotic. - these cells DO have a true nucleus

Plant vs. Animal Cell

• Most of the organelles found in animal cells are
  also found in plant cells ( eg. mitochondria,
  ribosomes, nucleus, etc.), but there are some
  differences.

• Plastids (chloroplasts chromoplasts)
• Leukoplasts
• Large central vacuole

• Centrioles
