Cells and Cell Parts
3.2
2
Cell Membrane

• A structure that forms the outer boundary and
  allows only certain materials into and out of the
  cell
• gatekeeper
• IN food, oxygen, water
• OUT wastes, water

3
Cytoplasm

• The gel-like material inside the cell membrane
• The Workshop
• Constantly moving
• Mostly water

4
Organelles

• Structures that float in the cytoplasm and have
  specific jobs
• They are different sizes and shapes

5
Nucleus

• The largest organelle
• The Mayor
• Directs all cell activity
• Contains DNA
• In center? nucleolus ribosomes are made

6
Chromatin

• Long strands of blue prints for cell operation
• The Recipes
• Made up of proteins and DNA

7
Endoplasmic Reticulum (ER)

• A folded membrane that moves materials around the
  cell
• UPS
• Mostly carries proteins from the nucleus
  throughout the cell

8
Ribosomes

• Structures in the cytoplasm that create proteins
• The smallest organelles
• Receive the recipes from the nucleus to create a
  certain protein
• Use amino acids to create proteins
• Proteins take place in nearly every cell activity

9
Golgi Complex

• Packaging and distributing organelles
• They move proteins within the cell or to the
  outside of the cell
• The Loading Dock

10
Mitochondria

• Break down food and release energy
• Energy company

11
Lysosomes

• Digest wastes and old cell parts
• Protects the cell from foreign invaders
• The Trash Collectors

12
Vacuoles

• The cells storage areas
• Plant cells have much larger vacuoles than animal
  cells
• Can store water, food, or waste
• Storage Garage

13
Cell Wall

• Plant cells only
• Rigid (hard) outer cell covering
• Gives plant protection and support

14
Chloroplasts

• Make food in plant cells
• Only in plant cells
• This is where photosynthesis takes place
