Cells Types & Organelles Mrs. Usher 8th Grade

What is a Cell? All living organisms are made up of cells. These organisms can be either: Uni-cellular (made of 1 cell) or Multi-cellular (2 or more cells)

Types of Cells There are 2 classifications of cells: Prokaryotic – cells without a nucleus Eukaryotic – cells with a nucleus Within Eukaryotic Cells, there are 2 main classifications: Animal Cells – Found in all organisms that are not producers Plant Cells – Found in organisms that are producers

Cells Prokaryotic Eukaryotic Bacteria Archaebacteria Protista Amoeba Euglena Algae Paramecium Diatoms Plants Animals Fungi Mushrooms Yeast

Prokaryotic Cells Prokaryotes are evolutionarily ancient. They were the first signs of life on Earth billions of years ago. Even with the evolution of more complex cells, prokaryotes are successful. Archeabacteria are still prokaryotic organisms.

Prokaryotic Cells Example Only has 5 parts: -DNA floating in the center -Cell Membrane - Cell Wall -Cytoplasm -Ribosomes

Animal vs. Plant Cells All animal and plant cells have the same organelles except for: Animal Plant -Lysosomes _Chloroplasts for photosynthesis - Centrioles -Vesicles -Large Vacuole - Cell Membrane

Cell Parts – Found in All Eukaryotic Cells Description: Plant-inside cell wall Animal –outer layer Double layer of phospholipids with proteins Semi-permeable Cell Membrane Function: Support and protection Controls movement of materials in and out of cell Maintains homeostasis

Cell Parts Nucleus Description: Large oval Holds DNA Function: Controls cell activities Contains the hereditary material of the cell

Cell Parts Nuclear Membrane Description: Surrounds nucleus Double membrane Semi-permeable Function: Controls movement of materials in and out of the nucleus

Cell Parts Cytoplasm Description: Clear, thick jellylike material Organelles found inside of cell membrane Function: Supports and protects cell organelles

Cell Parts Description: Endoplasmic Reticulum Network of tubes or membrane Smooth w/out ribosomes Rough with embedded ribosomes Connects to nuclear envelope and cell membrane Function: Carries materials through the cell Aids in making proteins

Cell Parts Ribosomes Description: Small bodies free or attached to ER Made of rRNA and protein Function: Synthesizes proteins

Cell Parts Mitochondria Description: Peanut shaped Double membrane Outer membrane is smooth Inner membrane folded into cristae Function: Breaks down sugar (glucose) to release energy in the form of ATP Site of cellular respiration

Today’s Agenda March 16, 2016 Homework Finish Cell Notes Tonight’s Sky Finish Cell Notes Plant vs. Animal Cell Diagrams Homework Complete cell structure/function chart AND color code the plant and animal cells

Cell Parts Golgi Apparatus Description: Stacks of flattened sacs Function: Modify proteins made by the cells Package and export proteins

Cell Parts Vacuole Description: Fluid-filled sacs Largest organelle in plant cells Function: Stores food, water, metabolic and toxic wastes Store large amounts of food or sugars in plants

Cell Parts Nucleolus Description: Found inside the cell’s nucleus May have more than one Disappears during cell division Function: Makes ribosomes

Cell Parts Lysosomes Description: (Uncommon in Plant cells, but very common in Animal cells.) Description: Small and round with a single membrane Function: Breaks down larger food molecules into smaller molecules Digests old cell parts

Cell Parts Cytoskeleton Description: Made of microtubules & microfilaments Function: Strengthen cell and maintains the shape

Organelles in Plants Only Cell Wall Description: Outer layer Rigid and strong Made of cellulose Function: Support (grow tall) Protection Allows H2O, O2, and CO2 to diffuse in and out of cell

Organelles in Plants Only Chloroplasts Description: Green, oval containing chlorophyll Double membrane with inner membrane modified into sacs Gel-like innermost substance called stroma Function: Uses energy from sun to make glucose for the plant Process called ‘Photosynthesis’ Releases Oxygen as a waste product

Organelles in Animals Only Centrioles Description: Paired structures near the nucleus Made of microtubule pairs formed into a cylinder Function: Separate chromosome pairs during mitosis

Cell Movement Cilia Description: Fine, hair-like structures Short, but numerous Function: Movement of cell

Cell Movement Flagellum Description: Whip-like structure Long, but few in number Function: Movement of cell

Check for Understanding 1. Which organelle is responsible for protein synthesis? ribosomes 2. Which organelle stores waste, water, and food? vacuole

Check for Understanding 3. What are the three differences between plant and animal cells? Shape (Animal = roundish & Plant = rectangular) ONLY plant cells have cell walls ONLY plant cells have chloroplasts Only animal cells have centrioles Lysosomes are more common in Animal cells Plant cells have a LARGE vacuole

Check for Understanding 4. Which organelle controls the cell? Nucleus 5. Which organelle converts sunlight into energy in photosynthesis? Chloroplast

Animal vs. Plant Cells Use your notes to create a Venn diagram or ‘T’ chart comparing the organelles of the Plant & Animal Cell. You may work with a partner.

To Review … PLANT CELLS ANIMAL CELLS 1. Cell wall 2. One large vacuole 3. Chloroplasts 4. Few to no lysosomes 5. Rectangular 6. Photosynthesis ANIMAL CELLS 1. No cell wall 2. A few small vacuoles 3. No chloroplasts 4. Lysosomes 5. ‘Roundish’ 6. Cellular Respiration
