Transcript Cells - Krum ISD

Warm Up
• On your Cells page of your IAN, make chart and
list the major structures found in each cell. (see
example on chalk board)
• Which cells are prokaryotes and eukaryotes?
• How do you know?
Animal Cell
Bacterial Cell
Warm Up
•Get out your IAN,
Agenda, Part of Cell
Chart, and something to
write with
•Everything else needs to
be on the floor
The cell is the basic structural and
functional unit of all known
living organisms.
NUCLEUS
 Directs all cell activities
 Contains instructions for
everything the cell does
 These instructions are
found on DNA
 Usually the largest
organelle
 Found in both plant and
animal cells.
CELL MEMBRANE
Allows food,
oxygen, & water
into the cell
Lets waste products
out of the cell
Outer covering,
protective layer
around ALL cells
CELL WALL
Protects the cell
Gives it shape
Made of cellulose
Found in plants, algae,
fungi, & most prokaryotes.
CYTOPLASM
Gel-like substance
Inside the cell
membrane
Holds the organelles
in place
70-90% water
Quick Check!
Number 1-4 in your IAN
1. Cytoplasm
2. Cell Wall
3. Cell Membrane
4. Nucleus
Match the cell part to
the job is does:
A. Controls the cell
B. Outer protective
layer in plants and
prokaryotes
C. Controls what enters
and leaves the cell
D. Fills the cell,
allowing chemical
reactions to occur
MITOCHONDRIA
Release energy from
food
This energy is released
by breaking down food
into carbon dioxide
Humans have an
average of 200 per cell
Found in ALL cells
VACUOLES
Temporary
storage spaces
Store food, water,
waste
Plant cells
usually have
larger vacuoles
than animal cells
CHLOROPLASTS
Green organelles that
make food
Found only in plant cells
CHLOROPHYLL
Found in chloroplasts
A green pigment that
gives leaves & stems their
color
Captures sunlight energy
that is used to produce
food called glucose
Glucose is a type of sugar
Quick Check!
Number 1-4 in your IAN
1. Mitochondria
2. Chloroplasts
3. Chlorophyll
4. Vacoule
Match the cell part to
the job is does:
A. Green pigment that
traps light energy in
plants
B. Storage compartment
C. Release energy for
cell
D. Organelle that holds
chlorophyll for food
production in plants
