Transcript What type of cells did you observe?

Aim: How can we describe the
structure and function of cell
organelles?

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 take in food
 Transport – to move materials
 Cell respiration – Make Energy: ATP
 Excretion – to get rid of waste
 Synthesis – to build, to make
 Regulation – to control
 Growth – to increase in size
 Reproduction – to make offspring

Define:
Homeostasis
Cellular Respiration
Aim: What are the various functions
of an organelle?
CELL MEMBRANE
FUNCTION:
 Barrier
to protect the cell.
 Controls what comes in and out.
CELL WALL
FUNCTION:
Provides support
and protection for
the cell and allows
materials in and out
of the cell.
 FOUND IN
PLANT CELLS.

MITOCHONDRIA
FUNCTION:
 Powerhouse
of the cell.
Makes energy or ATP from food and
oxygen.
CYTOPLASM
FUNCTION:
To protect and support the
organelles within the cell.
•
ENDOPLASMIC RETICULUM
FUNCTION:
 Transportation
route of cell.
Materials travel
through it.
 2 Types: Rough ER
(has ribosomes) &
Smooth ER
GOLGI APPARATUS
FUNCTION:
 Proteins
from ER come here. Labels
and packages the proteins, gives them
a direction to follow.
RIBOSOMES
FUNCTION:
They FORM proteins
 Can be found in cytoplasm or on
Endoplasmic Reticulum (Rough)

VACUOLES
FUNCTION:
 Store
materials such as
water, salt, proteins, and
carbohydrates.
 MANY SMALL ONES
IN ANIMAL CELLS,
AND ONE BIG ONE
IN PLANT CELLS.
CHLOROPLASTS
FUNCTION:
Use energy from sunlight
to make energy-rich food
molecules in a process
known as
PHOTOSYNTHESIS
 FOUND IN PLANT
CELLS!

CENTRIOLES
FUNCTION:
•
Involved in animal cell division
• FOUND ONLY IN ANIMAL CELLS
NUCLEUS
Found in
eukaryotic cells
only!
 Function: Controls
most cell processes
and contains the
hereditary
information DNA (THE
BRAIN)

THE BRAIN
LYSOSOMES
FUNCTION:

Contain enzymes that can break down
nutrients. Also they break down dead
organelles.
CILIA & FLAGELLA
FUNCTION:

Made of protein and
help with the
movement of
individual cells
