Cells
Who discovered cells?
Robert Hooke
What is the function of the mitochondria
Provides energy
Define selective permeability
Picks and chooses what goes in or out
Do autotrophs or heterotrophs use photosynthesis? Why?
Autotrophs make their own food
"Coins" the body can use for energy
ATP
What was the scientist who discovered cells looking at when he discovered them?
Cork
Which type of cells have a cell wall
Plant cells
What kind of head and tail do phospholipids have? What does this mean?
Head is hydrophilic (water loving) and tail is hydrophobic (water hating)
What is the main product from the light-independent stage of photosynthesis?
Glucose (or sugar)
What is the difference between aerobic and anaerobic
Aerobic- needs oxygen to function
Anaerobic- doesn't need oxygen to function
List the order in which cells are organized into living things
Cells -> Tissue -> Organ -> Organ System -> Organisms
A protein is first assembled and then packaged and marked for delivery to the correct location. In order, what two organelles are involved in this?
Ribosome and Golgi Apparatus
What kind of molecules can pass through membrane without help
Small
What two molecules do the protons and electrons use to form glucose?
Carbon dioxide and water
Why is cellular respiration necessary?
Our body can't use glucose as a form of energy, so we have to convert it to a form we can use (ATP)
According to the cell theory, would organic material be able to form a cell on its own in the right conditions? Give your answer and which part of the cell theory explains it
No; Cells come from other cells
A scientists observes that a cell can make its own food using sunlight. Which organelle allows this?
Chloroplast
What transport protein lets molecules pass through if they fit
Channel
Give one example of how we INDIRECTLY use photosynthesis
1) Eating plants that use photosynthesis
2) breathing oxygen
Which stage of cellular respiration produces the most ATP
The citric acid cycle
If an organism was made up of two cells, would it have a nucleus? Why?
All eukaryotes are multicellular
Need all organelles for entire cell to work. Ex: without ribosomes, no protein would be built
What is necessary for carrier protein to work?
A molecule to open the protein and let the first molecule pass through
What would happen to a plant if the chloroplasts were damaged?
Sunlight could not be absorbed and no oxygen would be produced
Which stage of cellular respiration can yeast NOT perform? Why?
The citric acid cycle; it is aerobic
