Unit 3: Organizations and Patterns of Life
Topic: Cell Organelles
Key Objectives
What You’ll Learn
A. the structure of cell parts to their functions.
B. The differences between plant cells and animal cells
Why do we study cells?
bodies are made up of cells
cells do all the work of life!
Regents Biology
The Jobs of Cells
Cells have 3 main jobs
make energy
make proteins
need energy for all activities
need to clean up waste produced
while making energy
proteins do all the work in a cell,
so we need lots of them
make more cells
for growth
to replace damaged or diseased cells
Our organelles
do all these
jobs!
Why do cells need energy?
to fuel daily life functions such as
ATP
Growth
Repair
Reproduce
Remove waste
Organelles: tiny structures inside
the cell
Why are cell organelles are important?
each organelle/structure has a specific job to
do to keep the cell alive
They’re like
mini-organs!
Model Animal Cell
Organelle # 1
Cell membrane
phosphate
“head”
Functions
separates cell from outside
controls what enters or leaves cell
O2, CO2, food, H2O, nutrients, waste
recognizes signals from other cells
allows communication between cells
lipid “tail”
Organelle # 2
cytoplasm
Function
jelly-like material holding
organelles in place
cell membrane
cell boundary
controls movement
of materials in & out
Regents Biology
recognizes
signals
Organelle # 3
Vacuoles
Functions
Storage site
Storing mostly
cellular wastes

Organelle # 4
Lysosomes
Functions
digest food
digest broken or
damaged
organelles
Digest foreign
particles(bacteria)
lysosomes
digesting broken
organelles
small food
particle
vacuole
digesting food
Regents Biology
cytoplasm
jelly-like material holding

organelles
Organelle # 5
Mitochondria
Function
make ATP energy from cellular respiration
sugar + O2 ATP
fuels the work of life
in both animal &
plant cells
Regents Biology

organelles
Organelle # 6
Ribosome
Making proteins
What are proteins used for by cells?
muscle fibers, hair, skin, claws
enzymes (speed up chemical reactions)
signals (hormones) & receptors
The ribosomes look
like tiny dots inside
the cell.
Regents Biology
Why are proteins so important?
Answer: Proteins do all the work!
one of the major job of cells is to make proteins,
because…
proteins do all the work!
structural
enzymes
signals
receptors
DNA
