1 Cheek Cells Bacterial Cells Elodea Cells OnionCells 400x

2 Organelles specialized structure that performs important cellular functions little organ

3 Type of Cell: Plant Prokaryote (bacteria) Fungi Some protists Structure: Rigid outer layer of cell. Cellulose for plants. Chitin for fungi Peptidoglycan for bacteria. Function: Support Protection

4 Type of Cells: All cells Structure: Fluid mosaic lipid bi-layer Function: Control movement in and out of cell Selectively permeable – only let certain substances in and out of the cell Barrier from outside environment cell membrane animation

5 Types of Cells: All cells Structure: Clear, thick jelly-like material Function: Support cellular organelles Move nutrients in cell

6 Types of Cells: Eukaryotic Cells (Plant, Animal, Fungi, Protist) Structure: Large, oval shape Near center Double membrane with nuclear pores (holes) Function: Contains and protects genetic information (DNA) Controls the cell

7 A. Animal B. Plant C. Bacteria D. Fungi

8 1. Mitochondria 2. Nucleus 3. Cytoplasm 4. Golgi Apparatus

9 A. Nucleus B. Cell wall C. Cell membrane D. Cytoplasm

10 1. Cell membrane 2. Cytoplasm 3. Nucleus 4. Ribosome

11 Types of Cells: All cells Inside nucleus in eukaryotic cells or in middle of prokaryotic cells Structure: Double helix of nucleic acids DNA is coiled to form chromatin and wound up even more into organized packages of DNA called chromosomes Function: Genetic information (blue- print of life) Contains the code for making proteins

12 Types of Cells: Eukaryotic (plant, animal, fungi, protist) Structure: Small round structure inside the nucleus Function: Makes ribosomes

13 1. Plant 2. Animal 3. Bacteria 4. All of the above

14 1. Chloroplast 2. Vesicle 3. Cell wall 4. Cytoplasm

15 Types of Cells: Eukaryotic (plant, animal, fungi, protist) Structure: Fluid-filled sacs Larger in plants Function: Stores waste, food, water for later use

16 Types of cells: Animal cells Some protists Structure: Small, round compartment that holds digestive enzymes Function: Breakdown large food particles Digest old cell parts Clean up

17 1. Transport materials 2. Control the cell 3. Store water and nutrients 4. Protect the cell

18 Microtubules & Microfilaments A network of protein fibers extending throughout the cytoplasm

19 Types of Cells: All Cells Structure: Twisted chain of proteins Thinnest protein fibers in the cell Function: Help maintain shape and supports the cell cause cytoplasmic streaming in plant cells

20 Types of Cells: Eukaryotic Structure Hollow tubes made of Protein Function Facilitate the movement of vesicles Motor proteins

21 Cilia Structure: Tiny hair-like projections on the outside of certain cells Function: Moves materials around the outside of the cell Ex: cells found in the lining of the trachea (windpipe) Moves mucus and dirt out of the lungs Flagella Can be found in some prokaryotic & eukaryotic cells Structure: Long whip-like tail Function: Moves the cell Ex: sperm cells

22 1. Rough ER 2. Smooth ER 3. Cytoplasm 4. Lysosome

23 1. Digestion of food 2. Movement of cell 3. makes lipids 4. Contains DNA

24 Types of Cells: All Cells Structure: Small organelles made of RNA No membrane Floating free in the cytoplasm or attached to Rough ER Function: Help make proteins

25 Type of Cells: Eukaryotic (plant, animal, fungi, protist) Structure: Network of folded tubes or membranes ROUGH ER: Ribosomes attached SMOOTH ER: Nothing attached Function: Rough ER: help make proteins Smooth ER: makes lipids (AKA FATS) Package materials (proteins or lipids) into transport vesicles

26

27 Types of Cells: Eukaryotic (plant, animal, fungi, protist) Structure: membranous sac Function: transport of materials made by the cell (lipids and proteins) Secrete materials to the outside of the cell

28 Location: Eukaryotic (plant, animal, fungi, protist) Structure: Flattened membranous sacs (like a stack of pancakes) Function: Modifies lipids & proteins Package materials into secretory vesicles to send them outside of the cell

31 1. Cell Membrane 2. Endoplasmic Reticulum 3. Cytoplasm 4. Lysosome 0

32 1. Make lipids 2. Make proteins 3. Control the cell 4. Package and transport materials

33 1. Make lipids 2. Control cell movement 3. Store nutrients 4. Help make proteins

34 Types of Cells: Eukaryotic (plant, animal, fungi, protist) Structure: Bean-shaped organelle with folded inner membranes Function: Make energy (ATP) Cellular Respiration occurs here Convert food, oxygen, and water into useable energy

35 Types of cells: Plant Cells Structure: Green ovals containing chlorophyll (green pigment) Function: Use energy from the sun to make food for the plant (photosynthesis)

36 Endosymbiotic theory – Mitochondria and chloroplasts, the two energy related organelles, arose when a large eukaryotic cell engulfed independent prokaryotes This explains why they have a double membrane and why they have genetic material separate from the nucleus

37 1. Make lipids 2. Make proteins 3. Control the cell 4. Make energy

38 1. Mitochondria 2. Chloroplast 3. Golgi apparatus 4. Lysosomes

39 1. Plant 2. Animal 3. Eukaryote 4. Prokaryote

40 1. Nucleus 2. Endoplasmic reticulum 3. Cell Wall 4. Cell Membrane
