  1. What is everything living composted of ? Unit A – Lesson 1 Correct, cells!

  2. All living things are made up of cells. Bacteria cells Fungi cells Plant cells and Animal cells

  3. 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.

  4. Plant cells Cell wall 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. vacuole vacuoles cytoplasm nucleus

  5. Plant Cells nucleus • 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. cytoplasm Water vacuole Cell wall Cell membrane

  6. Plant 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 wall Cell membrane Water vacuole Chloroplast l nucleus

  7. Review Question #1:What do these plant cell organelles do? A B chloroplasts cell wall C D vacuoles cytoplasm

  8. Question #2: Which gas is used by plants during photosynthesis?- A carbon dioxide B oxygen C nitrogen D phosphorus

  9. Answer to question #2. • You got it! A • Plants use carbon dioxide during photosynthesis and they excrete (their waste) oxygen.

  10. Question #3: Which of these is the source of energy for photosynthesis? A Gravity B Electricity C Magnetism D Sunlight

  11. Answer to #3: • Yes, sunlight D. • Sunlight is the source of energy for plant photosynthesis.

  12. Can you name some of theParts of a PLANT CELL?

  13. 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.

  14. Animal Cells 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. nucleus

  15. 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

  16. Animal Kingdom:Can you classify these animals? butterfly hamster mouse spider humans worm seahorse turtle frog fish octopus seastar

  17. Animal Kingdom:Answers Vertebrates Invertebrates

  18. Can you name some of theParts of an ANIMAL CELL?

  19. Fill in the empty rectangles. You may want to use your science books for help. (pages A8 & A9 PlantCells Animal Cells Name _______________________
