The main function of the circulatory system.
a) Break down food
b) Carry oxygen and nutrients around the body
c) Send messages through nerves
d) Support the body structure
Carry oxygen and nutrients around the body
The part of the microscope that you look through.
The ocular lens.
The organelle responsible for making energy.
Mitochondrion
This cell has a long tail (flagellum) and lots of mitochondria.
sperm cell
This long muscular tube pushes food from the mouth to the stomach using a wave-like motion called peristalsis.
oesophagus
This component of blood carries oxygen.
When you are using a simple compound light microscope, the image will appear to be:
A characteristically green organelle only found in plant cells.
chloroplast
Containing numerous mitochondria to enable contraction and movement
muscle cell
This organ removes water from undigested food and forms solid waste (faeces).
large intestine
The part of the heart that pumps oxygenated blood to the body.
Left Ventricle
I am the part of the microscope in which the ocular lens is located.
Eyepiece
Helps plants maintain shape, storage, digestion, and waste removal.
vaculole
I guard the gate of the plant’s green skin
guard cell
I don't need to consume "food" as I can make my own but every day I wake up and choose violence.
Venus Flytrap
A student runs 200 metres and notices their heart rate increases. Explain why this happens using your understanding of the circulatory system.
When the student runs, their muscles need more oxygen for energy, so the heart rate increases to pump oxygen-rich blood faster to the working muscles.
The maximum magnification of our compound microscopes.
400x
A membrane-bound organelle that houses the genetic material in eukaryotic cells,
nucleus
They help absorb nutrients by increasing the surface area.
villi
This organ does both chemical digestion (with enzymes and acid) and mechanical digestion (by churning the food).
The stomach
A cut on the skin starts bleeding. Explain the role of platelets in stopping the bleeding.
When the skin is cut, platelets stop bleeding by quickly traveling to the wound, sticking to the damaged vessel, and forming a temporary plug.
The most expensive type of microscope.
The electron microscope.
A thin layer that surrounds the cytoplasm of all prokaryotic and eukaryotic cells, including plant and animal cells. It is a selectively permeable cell organelle,allowing certain substances inside the cell while preventing others to pass through.
cell membrane
I’m green and lean, found in a leaf,
I allow O2 in and CO2 out.
Stomata
This substance produced by the liver isn’t an enzyme, but it helps break up large fat droplets into smaller ones, increasing the surface area for enzymes to act.
