1
Organisms Are made of Organ Systems
2
Organ Systems
3
Organs Are made of Tissues (heart tissue)
4
Tissues Are made of Eukaryote Cells
5
Eukaryote Cells Are made of Parts
6
Each cell part has a role in Performing the Cell’s Job, which is
7
Structure of a eukaryote cell Protective layer or layers surrounding the cell’s interior (cell wall/cell membrane) Cytoplasm Organelles within the cytoplasm Nucleus
8
All Cells have a Cell Membrane
9
The Cell Membrane Protects the cell Allows only certain materials to enter and exit the cell – selectively- permeable Made of a lipid bi-layer*.bi-layer*.
10
Nucleus
11
The Nucleus Made of 1.Nuclear Membrane/Envelope surrounding the nucleus (selectively permeable) 2.Chromosomes – composed of DNA wrapped around proteins 3.Nucleolus – produces RNA
12
The Nucleus DNA determines 1.which proteins the cell produces 2.how much of each protein the cell produces
13
Cytoplasm
14
Semi-fluid material enclosed by the cell membrane Organelles float in this material
15
Organelles A membrane-bound compartment or structure in a cell that performs special functions. A
16
Free Ribosomes
17
Rough Endoplasmic Reticulum with Ribosomes attached
18
Ribosomes and the Rough Endoplasmic Reticulum Ribosomes: Protein synthesis occurs here Rough ER: covered with ribosomes Once protein molecules are made, the rough ER folds the molecules, and sorts them according to function and destination in the cell*cell*
19
Smooth Endoplasmic Reticulum with No Ribosomes
20
Smooth Endoplasmic Reticulum Provides extra surface area for the action of enzymes.
21
Golgi Apparatus
22
The ER sends proteins to the Golgi Apparatus Here carbohydrates and lipids are attached to proteins and they are sent to their final destination
23
Mitochondrion(a)
24
Mitochondrion Cell respiration occurs here! Cell respiration releases ENERGY from molecules of food This energy is used for all cell functions
25
Cytoskeleton
26
A network of fibers that provides physical support and structure to the cell Made of microtubules and microfilaments.
27
Cytoskeleton The cytoskeleton is responsible for cell shape, movement of the cell as a whole (in one celled organisms), and movement of organelles in the cell.*
28
Certain Cell Parts are ONLY found in Plant Cells OR Animal Cells
29
Animal Cells have organelles called Lysosomes
30
Lysosomes Digest cellular waste and obsolete molecules and organelles.
31
Animal Cells have organelles called Centrioles
32
Centrioles Play a role in reproduction of animal cells
33
Plant Cells have organelles called Chloroplasts
34
Chloroplasts Site of photosynthesis in plant cells Photosynthesis produces carbohydrates* carbohydrates*
35
Plant Cells have Cell Walls
36
Cell Walls Provide support and protection for cell Provide rigidity to cell – allow plants to be tall without a skeleton Found in plants, fungi, algae and most prokaryote cells.
37
Cell Walls Made of carbohydrates and protein. One type of carbohydrate is cellulose = wood and paper. The presence of cell walls allows large plants to stand tall without a skeleton. Selectively permeable
38
Plant Cells have Large Central Vacuoles
39
Large Central Vacuoles Provides storage for water, salts, waste in plants Animal cells have multiple small vacuoles (not located in center of cell)
40
The Cell as a Factory
41
The Inner Life of a Cell
42
Summary – Use your notes 1.Make a Venn Diagram showing which cell parts are found only in Animal Cells, only in Plant Cells and in both types of cells. 2.Which cell parts are necessary for the physical structure of the cell? 3.Beginning with the nucleus and ending with the Golgi Apparatus Make a table: Name and describe the job of cell parts related to making proteins. 4.Name and describe the job of cell parts related to food and energy.
