Robert Hooke
15
Prokaryotic cells have ___________ ___________________, are small and simple and lack membrane bound __________________________.
no nucleus, organelles
15
This organelle is responsible for regulating the passing of nutrients into the cell and getting rid of waste out of the cell.
cell membrane
15
What is the purpose of a decomposer and why would you NOT find chloroplast in one of them?
To break down the remains of dead organisms so that the Earth is not covered in waste; decomposers are heterotrophs, not autotrophs & do not need chloroplast
15
This organelle provides support and protection to plants, so much so that animal cells do not have them. What organelle and why don't animals have them?
cell wall; they would restrict movement
15
Plants are not active and require less energy to function. Animal are very active. Therefore you would expect to find more of what organelle inside animals vs plants?
mitochondria
15
The largest organelle inside a plant cell hold water and other waste. It can be compared to a storage container. What organelle is this?
vacuole
15
Inside this important organelle, DNA (genetic material) is stored. What organelle is the control center?
nucleus
15
This substance, pigment is green in color and found inside an organelle in plant cells. This pigment allows absorption of sunlight energy from the sun.
chlorophyll
15
What is the purpose/function of lysosomes only found in animal cells?
get rid of waste; digest waste and foreign matter
15
In a school setting, the nucleus compares to what?
the principal
15
When an item is placed in water overnight and swells, which cellular transport process is taking place?
osmosis
15
Which form of cellular transport requires energy to move large particle into the cell from the outside?
endocytosis
15
In which direction does passive transport (no energy required) move materials across the membrane?
high to low, with the natural flow or gradient
15
In ____________________ transport, materials are moved from low to high concentration.
