Remaining Cell Parts

1
Remaining Cell Parts

• Organelles little organs or parts inside the
  cell

2
Nucleus

• Made up of
• Nuclear Membrane
• Chromatin
• Nucleolus
• Nuclear pores

3
Nucleus

• Controls cell processes contains DNA

Nuclear Membrane

• Surrounds nucleus
• Made of two layers
• Provides support and protection for the nucleus

4
Chromatin

• In nucleus
• Made of DNA Protein which gives us chromosomes.
• Contain instructions for traits characteristics
  
• (looks like cooked spaghetti)

Nucleolus

• Inside nucleus
• Produces ribosomes for the cell (pink center in
  the drawing)

Nuclear Pores

• Holes which allow material to move into or out of
  the nucleus.

7
Cytoplasm

• Cyto cell
• Fluid-like mixture
• Supports the cell organelles.

8
Centrioles

• Aid in cell division
• There are 2 in cell
• Only found in animal cells.

9
Cytoskeleton

• Microtubules maintain cell shape and help form
  the spindle in cell division. (hollow)

• Microfilaments aid in movement and support.
  (solid)

10
Cell Wall

• Provides support and protection for a plant cell.
  Found only in plants.

11
Cell membrane

• Regulates what enters and leaves a cell
• Provides protection and support for the cell

12
Cell Wall vs. Cell Membrane?

• Cell wall is ONLY in plant cells
• Cell membrane is in all cells
• Plant cells have both a cell wall AND a cell
  membrane.
