Plant Cell.
What are some differences between Animal and Plant Cells?
Both animal and plant cells have the same components, other than these few. Plant cells have a cell wall, chloroplasts and one main vacuole, while animal cells do not have a cell wall, or chloroplasts. Animal Cells have a few vacuoles.
Why are cell membranes selectively permeable?
They are responsible for regulating what goes in and out of cells - selectively permeable means not everything gets through. So cell membranes can make sure that the cell gets what it needs, while keeping harmful substances out.
Provide a diagram of Osmosis.

What is cellular respiration?
A process where oxygen and nutrients are converted into energy.
Where does cellular respiration occur?
In all cells.
Why is cellular respiration important?
It produces energy for the body and gets rid of wastes (carbon dioxide).
Describe the heart. (Circulatory system)
Includes 2 pumps that push blood around.
Describe the arteries and veins. (Circulatory system)
Arteries bring blood to other parts of the body, and veins carry blood back to the heart.
Describe the capillaries. (Circulatory system)
Capillaries are tiny, thin, and narrow blood vessels that allow for blood cells to pass through in a single file. They help increase the rate of gas exchange between the blood and cells.
Describe the components of blood? (Circulatory system)
- Red blood cells carry oxygen.
- White blood cells fight infection.
- Platelets stop bleeding in cuts.
- Plasma is the liquid portion of blood that transports cells and carries waste.
Describe the kidneys. (Excretory system)
Responsible for filtering blood, straining out urea, and getting rid of excess water.
Describe the ureters. (Excretory system)
Tubes connecting the kidney to the bladder, where urine is stored until pushed through the urethra.
Describe the liver. (Part of both excretory and digestive systems)
- Converts ammonia to urea.
- All the blood leaving the stomach and intestines passes through the liver. The liver processes this blood and breaks down, balances, and creates nutrients.
Describe the skin’s function in the excretory system.
Excretes salts from your body when you sweat.
Describe the stomach. (Digestive system)
Temporarily stores food, and produces enzymes and other specialized cells to digest food.
Describe the esophagus. (Digestive system)
Carry’s liquid and food from your mouth to your stomach.
Describe the small intestine. (Digestive system)
Further digests food coming from the stomach, also absorbs nutrients from the food.
Describe the large intestine (Digestive system)
Absorbs water and salts from the material that has not been digested as food. The large intestine also gets rid of any waste products left over.
Describe the brain. (Nervous System)
Receives information from all sensory organs, also receives information from inside the body as well.
Describe the spinal cord. (Nervous System)
The spinal cord connects your brain to your lower back. It carries nerve signals to and from your brain. These nerve signals allow you to move your body, and feel different things.
Label the Parts of the Microscope: https://docs.google.com/presentation/d/1DhKQuUb-xDWoINDQJMX-CjtdEHKFDP50gK47_mXZtRk/edit#slide=id.g134b3b1d98d_1_57
a) Eyepiece
b) Eyepiece tube
c) Coarse focus
d) Fine focus
e) Arm
f) Objective lenses
g) Stage
h) Light or mirror
How do you use a microscope?
You place the slide on the stage under the 4X lens, then you focus with the coarse focus, then fine focus knobs. When the microscope is focused turn to the 10X lens, and focus with the fine focus knob. Again, when the microscope is focused turn to the 40X lens and focus with the fine focus knob.
In the beakers shown, one side (either A or B) represents a carrot stick, and the other side represents a glass of water.: https://docs.google.com/presentation/d/1DhKQuUb-xDWoINDQJMX-CjtdEHKFDP50gK47_mXZtRk/edit#slide=id.g134b3b1d98d_1_63
Which side represents the carrot stick, and which side represents the glass of water?
𝗔 represents the carrot because it has a lower concentration of water. 𝗕 is the water, so osmosis levels the concentration of the carrot and the glass of water by allowing water particles into the carrot, and making the concentration even on each side.
