CELLS Plant and Animal
Cells �Cells are the basic units of function in all living things. �Cells in animals and plants have unique forms that allow each to take part in processes that are necessary for the cell and or/living thing to survive.
Organelles � What is an organelle? � Organelles are to cells what organs are to the body. � They carry out the individual tasks of gaining and working with energy, as well as directing the overall behavior of the cells. � Let’s familiarize yourself with the organelles of the animal and plant cell.
Organelles : Nucleus: Nucleolus: Nuclear Envelope: Centrioles: Mitochondria: Ribosomes: Function : Contains the DNA and RNA and manufactures proteins In nuclei where ribosomes are synthesized. Membrane of lipids and proteins that surrounds nucleus Structure that appears during mitosis(cell division) Energy producers of the cell Produce proteins
More Organelles Golgi Bodies: Chloroplasts: Packages Proteins Involved in photosynthesis (in plants) Vacuoles: Stores waste, nutrients, and water Lysosome: Contains digestive enzymes, mostly in animal cells Endoplasmic Reticulum: Passageway that transports proteins from the nucleus **Rough ER is covered in ribosomes, Smooth ER is not!**
These are parts of the cells, but ARE NOT Organelles � Cell membrane: � Cell Wall: � Cytoplasm: Semi-permeable lining that surrounds the cell Is a stiff non-living wall that surrounds the cell membrane made of cellulose (in plants) Jelly-like material surrounding the organelles
Venn Diagram � At this point, I want you to draw a Venn diagram, including an animal cell and a plant cell, in your notebook. (Do Not Look Ahead At the other Slides). Remember your Venn diagram is to look like two circles that overlap each other. You will write the similarities in organelles in the inside circle and the differences in the outside circles.
Cheat Sheet! How accurate was your Venn Diagram? contain: � Nucleus, Nuclear Envelope, Chromosomes- which carry the genes or the DNA. � Cytoplasm � Mitochondria � Cell membranes � Any others? Plant cells have nonliving rigid cell walls. � Plant cells contain chloroplasts which contain chlorophyll, a green chemical needed for photosynthesis. � Plant cells contain a large vacuole; animal cells never contain large vacuoles. � Plant cells are regular in shape; animal cells are irregular in shape. � Both � Similarities Differences
