1Living Systems Part III Plant&AnimalCellsDr. Marjorie Anne Wallace,Elementary Science Resource Teacher
2All living things are made up of cells. Bacteria cellsProtozoan cellsFungi cellsPlant cells andAnimal cells
3Plant Cells Plants are classified into the Plant Kingdom. Plants may be grouped intoVascular or non-vascularPlants are made up ofplant cells.Plant cells have:- a strong cell wall,-large water vacuoles, and-several chloroplast forphotosynthesis used inenergy & food production.
4Plant cells Plant cells are usually square or rectangle shaped. Cell wallCell membranePlant cells are usually square or rectangleshaped.Plant cells have:-cell wall,- cell membrane,--chloroplasts, -nucleus,-large vacuoles for food & water, and- cytoplasm to protect all the internal organelles.vacuolevacuolescytoplasmnucleus
5Plant Cells Multi celled organisms Cytoplasm is the clear jelly like matter that protects the inside cell organelles.Cell walls are found in plant cells but not in animal cells. They are stiff, non-living cell parts that help shape the plant cell.nucleuscytoplasmWatervacuoleCellwallCellmembrane
6Plant Cells*Cell membrane holds the cell together and lets substances pass in and out of its pores.Chloroplasts are organelles in some plant and protist cells. They contain chlorophyll that helps the plant cell store solar (SUN) energy.Photosynthesis.Plants are producers.Cell wallCellmembraneWatervacuoleChloroplastlnucleus
7Review Question #1: What do these plant cell organelles do? Bchloroplastscell wallCDvacuolescytoplasm
8Question #2: Which gas is used by plants during photosynthesis?- A carbon dioxideB oxygenC nitrogenD phosphorus
9Answer to question #2.You got it! APlants use carbon dioxide during photosynthesis and they excrete (their waste) oxygen.
10Question #3: Which of these is the source of energy for photosynthesis?A GravityB ElectricityC MagnetismD Sunlight
11Answer to #3: Yes, sunlight D. Sunlight is the source of energy for plant photosynthesis.
13What do animal cells look like? Animal cells tend to be sphere or round shaped.Animal cells have:-cell membrane to hold the cell together,-cytoplasm a watery gel inside the cell,-nucleus with a nuclear membrane, and-sometimes small vacuoles wherefood and chemicals are stored.
14Animal Cells -cytoplasm- jelly like gel that suspend organelles Each animal cell has:-a cell membrane- holds cell together and allows substances in and out of the cell,-cytoplasm- jelly like gel thatsuspend organellesinside the cell,-a nucleus- the control center;or the “Brain,” of the cell,-nuclear membrane- allows substances to pass in & outof the nucleus.nucleus
15Animal Kingdom Animals are classified into the Animal Kingdom. Animals are consumers.(They must eat food to live.)Animals can be grouped asInvertebrates or vertebrates.Invertebrate -No backboneVertebrates - Backbone present
