Standard - Virginia Science SOL 5.5 Living Systems
The student will investigate and understand that organisms are made of cells and have distinguishing
characteristics. Key concepts include:
a. basic cell structures and functions; b. kingdoms of living things
c. vascular and nonvascular plants; and d. vertebrates and invertebrates.
Plant and Animal Cells
You have already learned that atoms and molecules are the building blocks of matter.
Cells are the building blocks of all living things.
Even though a flower, a cat, and a grasshopper are very different, they are all made of cells.
Plant and Animal Cells
Cells in living things work together to carry out all the processes that allow an organism to stay alive.
A group of cells in your body work together to form yourcirculatory system. Another group of cells work together to form your respiratory system. Without cells, you wouldn't be alive!
Plant and Animal Cells
Cells are microscopic. They cannot be seen without a microscope. When viewed through a microscope, it is possible to see that while they are similar in many ways, there are some key differences between plant and animal cells. They have different shapes and some different parts.
Plant Cells
Plant cells are usually rectangular in shape. They are made up of many parts (organelles) including the cell wall, cell membrane, cytoplasm, nucleus,
chloroplasts, vacuoles, and mitochondria.
Let's learn more about plant cells!
Cell WallPlant Cells
The cell wall gives shape and support to the plant cell. It
surrounds the cell and protectsthe other parts of the cell.

Plant Cells
Cell Membrane
The cell membrane is a thin liningjust inside the cell wall. The cellmembrane controls what flows in and out of the cell (food, waste, water, oxygen).

Plant Cells
Cytoplasm
The cytoplasm is a jelly-likesubstance that fills the cell.All of the cell's organelles
are located in the cytoplasm.

Plant Cells
Nucleus
The nucleus is a round structureinside the cell. It controls all ofthe cell's activities. The nucleusis the command center of the cell.

Plant Cells
Vacuole
Vacuoles are storage facilities forthe cell. The vacuoles store foodor waste that will be used (food) orgotten rid of (waste) later.

Plant Cells
Chloroplasts
Chloroplasts are where the plantcell's chlorophyll is stored. Thisis what the plant uses to make itsown food.

Plant Cells
Mitochondria
The mitochondria are located in thecytoplasm. The mitochondria are thepowerhouses of the cell. They release stored energy.

Animal Cells
Animal cells are circular in shape. They have many of the came cell parts that plant cells do, but not all of them. The parts of the cell perform the same functions as in a plant cell.

Animal Cells
Can you guess why animal cells don't contain chloroplasts?
Animals don't make their own food, so they don't need the chloroplasts. That's also why you are not green!
Animal Cells
Can you guess why your cells don't have cell walls?
You have a skeleton to give you shape and support! You don't need cell walls!
