1
Cells Structure and Function
2
Cell Theory zAll living things are made of cells. zAll cells come from preexisting cells. zThe cell is the basic unit of organization in living things.
3
Two Types of Cells
4
Prokaryote zCells that lack internal structures surrounded by membranes. zCells with no defined nucleus. The DNA is a circular strand.
5
Eukaryote zCells with organelles surrounded by membranes.
6
Animal Cells zkzk zThis is what your animal cells should have looked like! zCan you identify any parts?
7
Plant Cells zThis is what your plant cells should have looked like. zWhat are the green structures?
8
Flip book of cell Organelles Title Page: Parts of a cell First Flap: Boundries Second Flap: Support and Locomotion Third Flap: Energy Fourth Flap: Assembly & Transport Fifth Flap: Storage Sixth Flap: Control
9
Parts of a cell:
10
Boundries
11
Divide this page into two sections
12
Plasma Membrane zSelectively permeable zControls what enters and leaves the cell. zMaintains chemical balance. zDefines the boundary of the cell.
13
Cell Wall zGives a firm structure to plant cells. zMade mainly of cellulose.
15
Divide this page into two sections
16
Cytoplasm zJelly-like substance that supports the organelles. zMany chemical reactions take place in the cytoplasm.
17
Cytoskeleton zSupport zScaffolding in the cytoplasm
19
Divide this page into two sections
20
Chloroplast zContain pigments that absorb energy needed to run photosynthesis. zFound in plants and some protozoans.
21
Mitochondria zProduces energy for the cell.
23
Divide this page into two sections
24
Endoplasmic reticulum zSystem of passages that transport substances around the cell. zTwo types: ysmooth yrough (has ribosomes)
25
Ribosomes zProtein synthesis
26
zStorage & Digestion
27
Divide this page into three sections
28
Vacuoles zMembrane bound containers for storage and transport of substances in the cell.
29
Lysosome zVacuole that contains digestive enzymes.
30
Golgi Apparatus zMembrane sacks that store newly produced proteins.
32
This page will have one drawing in the middle with four sections surrounding it.
33
Nucleus zControl center for the cell. zContains the information for all cell activities. zHas a double, selectively permeable membrane.
34
Nucleolus zProduces ribosomes
35
Chromatin zLong strands of DNA that hold the directions for all cell activity.
36
Centrioles zInvolved in cell division
