• Elementary Science Resource Teacher

All living things are made up of cells.

• Bacteria cells
• Protozoan 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 membrane
Cell wall

• 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.

Plant 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.

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.

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.

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.

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
