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!


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



controls what enters or leaves cell


O2, CO2, food, H2O, nutrients, waste
recognizes signals from other cells

allows communication between cells

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!
