Animal cells and plant cells

  1. 1. Animal Cells and Plant Cells
  2. 2. Animal cells
  3. 3. ANIMAL CELL Cytoplasm Nucleus Cell Membrane
  4. 4. You need to identify the different parts of a typical animal cell and relate the parts to the functions. parts of animal cell: • cell membrane, cytoplasm, nucleus
  5. 5. According to the cell theory, proposed over 150 years ago: • Most cells are very tiny and can only be seen with the aid of a microscope. A human body is composed of billions of cells! • The cells in the human body consist of blood cells, skin cells, brain cells and many others and each type of cells has different functions. • Despite their differences, most cells in living organisms have similar structures and functions.
  6. 6. Cell Membrane • A cell membrane keeps all the parts of the cell inside. • It controls what enters and exits the cell such as water, nutrients and waste and thereby protects and supports the cell. • It is the outermost layer in the animal cell.
  7. 7. Cytoplasm • Inside the cell, there is a large fluid-filled space called the cytoplasm. • It is a jelly-like substance composed of mainly water as well as substances like dissolved nutrients. • The cytoplasm fills up the space between the nucleus and the cell membrane.
  8. 8. Nucleus • The nucleus is located in the cytoplasm of the cell. • It controls and regulates all cell activities. It is the "control center" of the cell and it contains the cell's DNA. • It has a similar function to the brain of the body which is helping to control eating, movement, and reproduction.
  9. 9. Let’s summarise: Animal Cell - Functions Nucleus Cytoplasm Cell membrane control centre of the cell – stores information for cell functions jelly-like, where cell activities take place thin, controls the substances that enter or exit the cells
  10. 10. Examples of Cells found in Animals
  11. 11. Cheek Cells Can you identify the parts of the cell? - cell membrane, nucleus, cytoplasm
  12. 12. Red Blood Cells
  13. 13. Human Muscle Cells
  14. 14. Plant cells
  15. 15. You need to identify the different parts of a typical plant cell and relate the parts to the functions. parts of plant cell: • cell wall, cell membrane, cytoplasm, nucleus and chloroplasts
  16. 16. PLANT CELL Chloroplast Cytoplasm Nucleus Cell Membrane Cell Wall
  17. 17. • A cell membrane keeps all the parts of the cell inside. Cell Membrane • It controls what enters and exits the cell such as water, nutrients and waste and thereby protects and supports the cell. • It is found just inside the cell wall in the plant cell.
  18. 18. • The cell wall is found in plant cells but not in animal cells. • This is the outermost layer in the plant cell. It is stiff and rigid and helps a plant keep its shape. • Cell walls allow materials like water and nutrients; waste, oxygen and carbon dioxide to pass to and from the cell membrane. Cell Wall
  19. 19. • Chloroplasts are only found in plant cells. They are responsible for photosynthesis. • Every green plant you see is working to convert the energy from the sun into sugars during the process of photosynthesis. Chloroplast • Plants are the basis of all life on Earth. They make sugars, and the byproduct of photosynthesis is the oxygen that we breathe. • Chloroplasts are green because of the pigment chlorophyll.
  20. 20. • Inside the cell, there is a large fluid-filled space called the cytoplasm. Cytoplasm • It is a jelly-like substance composed of mainly water as well as substances like dissolved nutrients. • The cytoplasm is found in both plant and animal cells, filling the space between the nucleus and the cell membrane.
  21. 21. • The nucleus is found in both plant and animal cells. • It is located in the cytoplasm of the cell. • It controls and regulates all cell activities. It is the "control center" of the cell and it contains the cell's DNA. • It has a similar function to the brain of the body which is helping to control eating, movement, and Nucleus
  22. 22. Let’s summarise: Plant Cell - Functions Nucleus Chloroplast s control centre of the cell – stores information for cell functions contain green pigment chlorophyll, needed in photosynthesis Cytoplasm jelly-like, where cell activities take place Cell membrane Cell wall thin, controls the substances that enter or exit the cells stiff wall which gives plant cells their shape
  23. 23. Examples of Cells found in Plants
  24. 24. Hydrilla Cells
  25. 25. Hydrilla Cells- Magnified Can you spot the cell wall, cell membrane, nucleus, cytoplasm and chloroplasts?
  26. 26. Onion Cells
  27. 27. Onion cell- Magnified Can you identify the parts of the cell?
  28. 28. Cells in a leaf stoma stoma
  29. 29. Cells in the stem xylem phloem
  30. 30. Differences between Plant and Animal Cells Plant Cell Animal Cell •Plant cells contain chloroplasts to make food from solar energy during photosynthesis. •Underground parts of plants usually do not contain chloroplasts. •Animal cells do not contain chloroplasts. •Plant cells contain cell wall. Animal cells do not have cell wall.
