Elementary Science Resource Teacher
All living things are made up of cells.
• Bacteria cells• Protozoan cells• Fungi cells• Plant cells and• 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• 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.

*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.

Review Question #1:
What do these plant cell organelles do?
chloroplasts cell wall
vacuoles cytoplasm
A B
C D
Question #2:
• Which gas is used by plants
during photosynthesis?-
A carbon dioxide
B oxygen
C nitrogen
D 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 Gravity
B Electricity
C Magnetism
D Sunlight
Answer to #3:• Yes, sunlight D.
• Sunlight is the source of energy for plant 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 CellsEach 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.
