Download What type of cells did you observe?

Aim: How can we describe the
structure and function of cell
organelles?
AIM: How can we describe the structure
and function of cell organelles?
DN: What are organelles? Name at least
two organelles and describe the function of
each one.
HW: Read pages 173-183, page 183 #1-6

CELLS
EUKARYOTIC CELLS
ANIMAL CELL
PLANT CELL
PROKARYOTIC CELLS
BACTERIA
Prokaryotes



All Bacteria
They DO NOT have membrane bound organelles.
They DO have:
 Cell Membranes
 Cell Walls
 DNA
 Ribosomes
2 Types of Eukaryotic Cells:
 Animal
Cell
 Plant Cell
 Both are complex, but there are
differences
What are those things inside the
cell?
 Organelles-
Specialized structures in
cells that perform important cellular
functions.
Life Functions
Nutrition – to get nutrients for energy
 Transport – to move materials from A to B
 Cell respiration – Energy: ATP
 Excretion – to get rid of metabolic waste
 Synthesis – to build, to make
 Regulation – to control
 Growth – to increase in size or number
 Reproduction – to make offspring

CELL MEMBRANE
FUNCTION:
 Protect
the cell.
 Controls what comes in and out.
CYTOPLASM
FUNCTION:
Protect and support the
organelles within the cell.
NUCLEUS
 Found
in
eukaryotic cells
only!
 Function: Controls
cell processes and
contains the
hereditary
information - DNA
ENDOPLASMIC RETICULUM
FUNCTION:
 Transport
of
materials
 2 Types: Rough ER
(has ribosomes) &
Smooth ER
RIBOSOMES
FUNCTION:
Protein Synthesi
 Cytoplasm or on Rough ER

GOLGI APPARATUS
FUNCTION:
Packages Proteins
MITOCHONDRIA
FUNCTION:
Powerhouse of the cell- cellular
respiration
Makes energy or ATP from food and
oxygen.
LYSOSOMES
FUNCTION:
Contain enzymes that can break down
nutrients. Also they break down dead
organelles.
VACUOLES
FUNCTION:
 Store
materials such as
water, salt, proteins,
and carbohydrates.
 MANY SMALL
ONES IN ANIMAL
CELLS, AND ONE
BIG ONE IN PLANT
CELLS.
CENTRIOLES
FUNCTION:
•
Involved in animal cell division
• FOUND ONLY IN ANIMAL CELLS
CHLOROPLASTS
FUNCTION:
 Photosynthesis
 FOUND IN
PLANT CELLS!
CELL WALL
 Support
FUNCTION:
and
protection for the
cell and allows
materials in and
out of the cell.
 FOUND IN
PLANT CELLS.
CILIA & FLAGELLA
FUNCTION:
 Made
of protein
and help with
the movement
of individual
cells
Animal cell
Plant cell

in common?
