ANIMAL CELL
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
  • 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
  • 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
  • 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
  • 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.

Plant cells
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
PLANT CELL
17
  • 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 found just inside the cell wall in the
    plant cell.

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.

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.
  • Plants are the basis of all life on Earth. They
    make sugars, and the by-product of photosynthesis
    is the oxygen that we breathe.
  • Chloroplasts are green because of the pigment
    chlorophyll.

20
  • 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 is found in both plant and animal
    cells, filling the space between the nucleus and
    the cell membrane.

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 reproduction.
