Home Learning: 3D model of a Cell You must choose whether you would prefer to build a 3D model of a Plant or an Animal cell Research/Google the organelles that belong to the type of cell you chose You can use any type of material you would like as long as your model is a 3D one. Yes your cell could be edible if choose to do so. You can also make a paper 3D model, as long as you are gluing your pieces and not just drawing/coloring. 22

Why continue to learn about cells!?? We can do a LOT… Protect our cells to prevent infection and other harmful effects Observe cells to diagnose disease Treat cells to heal illnesses Stop harming cells though our choices and actions STOP ZIKA!??? – scientists need to learn about cells in both humans and mosquitoes and the single celled organism that causes Zika.

Review: Prokaryotes vs. Eukaryotes Eukaryotes are/have: Big More Complex The nucleus houses the cell's DNA, keeps things organized Prokaryotes are/have: Small Less Complex No nucleus around the DNA No need for a special container because the cell is so small!!!

PARTS OF CELLS Organelles: Small, specialized structures inside cells such as the nucleus or mitochondria. All living things are made up of cells, but not all cells are the same.

Cell Membrane/Plasma Membrane Organelles Organelle Prokaryote Or Eukaryote Plant or Animal Cell Function   Cell Wall Both Plant Protects plant and some prokaryotic cells; supports cell. Cell Membrane/Plasma Membrane Controls what enters and exits a cell.  Cytoplasm Jelly-like substance that holds the organelles outside of the nucleus. Nucleus Eukaryote Holds the DNA (genetic information) of cells –Surrounded by a nuclear membrane with pores

Organelles Organelle Prokaryote Or Eukaryote Plant or Animal Cell Function   Nuclear Membrane Eukaryote Both Surrounds the genetic material and nucleolus Nucleolus Round body located inside of the nucleus. Chromatin The material that chromosomes are made of (Protein + genetic material) Mitochondria Cellular respiration occurs here to produce ATP → this is the power house of the cell.

Endoplasmic Reticulum Organelles Organelle Prokaryote Or Eukaryote Plant or Animal Cell Function   Ribosomes Both Where proteins are made Endoplasmic Reticulum (ER) Eukaryote “highway of the cell” and site of protein and lipid synthesis. Highly folded to increase surface area available to make more proteins and lipids Golgi apparatus Sorts and packages cellular products →like the post office of the cell. Pieces of the Golgi are pinched off to form vesicles that deliver the cellular products

Organelles Organelle Prokaryote Or Eukaryote Plant or Animal Cell Function   Lysosomes Eukaryote Both Breaks down waste products Vacuoles Stores water and waste, supports plant cell by exerting pressure on the cell wall. Plants have a large central vacuole. Chloroplast Plant Photosynthesis occurs here in plant cells. Microtubules Tube-shaped protein structures that help cells maintain their shape Cilia/Flagella Animal Located outside of the cell. Flagella helps the cell move around. Cilia helps move substances over or around the cell.

Hard outer layer that protects the cell from bursting or shriveling. Cell wall Hard outer layer that protects the cell from bursting or shriveling.

Cell membrane A soft, semi-permeable layer that protects the cell. Found in all cell types.

Cytoplasm The liquid in the cell and everything floating in it. Found in all cell types.

Nucleus The area of the cell where DNA is located. Usually in the center. Bacteria do not have a nucleus.

DNA / Chromosomes DNA gives the cell instructions for building proteins and moving materials. Bacteria have RNA, but not DNA.

A membrane that protects the nucleus. Nuclear envelope A membrane that protects the nucleus.

Mitochondria Mitochondria make energy for the cell. Bacteria do not have mitochondria.

Small structures that build proteins. Ribosomes Small structures that build proteins. Found in all cell types.

Storage areas that store water, nutrients, etc. Vacuole Storage areas that store water, nutrients, etc. Found in all cell types.

This is in a plant cell. It has one large central vacuole that stores water the plant needs to survive. It is LARGE and takes up a lot of space

cell membrane/plasma membrane

Large Central Vacuole Used to store water and other materials Vacuole We can get up and drink water when they need it and they cant they need to store it. Why do plant cells have certain organelles that animal cells do not? Plant cells and animal cells share most of the same organelles, but plant cells have a cell wall, chloroplasts and a larger central vacuole.

Chloroplasts Chloroplasts:  It is the site for photosynthesis in a plant cell. Animals don’t do photosynthesis.

Review: Cell Wall Rigid outer layer Provides structure and support for the cell Protects the cell membrane Cell wall: Provides rigidity, strength, protection against mechanical stress and infection. Animal Cell Wall

Note sheet output What are the two different types of eukaryotic cells? Nucleus, vacuole, cell wall, cytoskeleton: Which of these is found in plants but not animal cells? How is the vacuole different in plant cells? Plant and animal cell wall much larger holds water for plant

Note sheet output 4. Mitochondria or chloroplast: which is only found in plant cells? chloroplast - make food from sunlight (mitochondria are in BOTH animal and plant cells)
