Living Systems Plant & Animal Cells Dr. Marjorie Anne Wallace, Elementary Science Resource Teacher All living things are made up of cells. • Bacteria cells • Protozoan cells • Fungi cells • Plant cells • Animal cells Plant Cells • Plants are classified into the Plant Kingdom. • Plants may be grouped into Vascular or non-vascular • Plants are made up of plant cells. Plant cells have: - a strong cell wall, -large water vacuoles, and -several chloroplast for photosynthesis used in energy & food production. Plant cells Cell membrane • Plant cells are usually square or rectangle shaped. Plant cells have: -cell wall, - cell membrane, --chloroplasts, -nucleus, -large vacuoles for food & water, and - cytoplasm to protect all the internal organelles. nucleus Plant Cells nucleus cytoplasm Cell wall Cell membrane Water vacuole • 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. membrane holds the Plant Cells *Cell cell together and lets Cell wall Cell membrane Water vacuole nucleus l Chloroplast 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. Review Question #1: What do these plant cell organelles do? A chloroplasts C vacuoles B cell wall D cytoplasm Question #2: • Which gas is used by plants during photosynthesis?A B C D carbon dioxide oxygen nitrogen phosphorus Answer to question #2. • You got it! A • Plants use carbon dioxide during photosynthesis and they excrete (their waste) oxygen. Question #3: • Which of these is the source of energy for photosynthesis? A B C D Gravity Electricity Magnetism Sunlight Answer to #3: • Yes, sunlight D. • Sunlight is the source of energy for plant photosynthesis. Can you name some of the Parts of a PLANT CELL? CELL W ALL Cell MEMBRANE CYTOPLASM NUCLEUS & Nuclear Membrane CHLOROPLAST for Photosynthesis What 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 where food and chemicals are stored. Animal Cells nucleus Each animal cell has: -a cell membrane- holds cell together and allows substances in and out of the cell, -cytoplasm- jelly like gel that suspend organelles inside the cell, -a nucleus- the control center; or the “Brain,” of the cell, -nuclear membrane- allows substances to pass in & out of the nucleus. Animal Kingdom • Animals are classified into the Animal Kingdom. Animals are consumers. (They must eat food to live.) • Animals can be grouped as Invertebrates or vertebrates. Invertebrate -No backbone Vertebrates - Backbone present Animal Kingdom: butterfly Can you classify these animals? hamster mouse spider humans worm seahorse frog octopus turtle fish seastar Animal Kingdom:Answers Invertebrates Vertebrates Can you name some of the Parts of an ANIMAL CELL?
