WARM UP: CELL REVIEW

1
WARM UP CELL REVIEW

• 1) Which type of cell does NOT have a membrane
  bound nucleus?
• 2) Which organelle makes energy for the cell?
• 3) Which organelle is the control center?
• 4) This cell part protects the cell and decides
  what can enter and what can leave.
• 5) This organelle cleans up all damaged cell
  parts.
• EC. This organelle helps the cell reproduce and
  divide.

Notes 5

• Cells and organelles

3
Cell

• Makes up organisms.
• Smallest unit of life.
• 2 types
• prokaryotic
• no membrane bound organelles
• eukaryotic
• have membrane bound organelles

4
Organelle

• little organs of the cell
• Units inside the cell with a specific job

5

• (Protein
• differentiates one cell from another)
• Nucleus
• control center of the cell
• Contains DNA / info
• Plasma membrane
• decides what enters / leaves the cell
• Ribosome
• make proteins
• Rough endoplasmic reticulum
• houses ribosomes
• makes proteins used inside outside cell
• makes lipids

6

• Smooth Endoplasmic Reticulum
• detoxifies cell
• makes lipids
• Golgi body / apparatus
• packages and delivers proteins in and out of
  cell
• Vacuole
• storage of extra water and nutrients
• Lysosome
• breaks down old cell parts
• Mitochondria
• Makes energy (ATP) for the cell

7

• Cytoplasm
• Fluid in cell containing water, nutrients
  used for metabolism
• Centriole
• needed for cell division / reproduction
• Chloroplast
• makes food for plants
• photosynthesis occurs here
• Cell wall
• rigid structure outside plasma membrane
• support and protection for plant cells
