Download Notes#___: Cells and organelles

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
Cell
• Makes up organisms.
• Smallest unit of life.
• 2 types
• prokaryotic:
•
no membrane bound organelles
•
eukaryotic:
•
have membrane bound organelles
Organelle
• “little organs” of the cell
• Units inside the cell with a specific job

•
(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
• 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
• 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
