Lab Material Quiz Flashcards
What do chloroplasts do?
Capture sunlight
What type of cell carries out photosynthesis?
Plant cell
What is the organelle in which respiration occurs?
Mitochondria
What does the Mitochondria do?
The powerhouse of the cell (supply energy)
Which type of cells carry out respiration?
Plant and Animal cells
What is an autotroph?
An organism that uses the sun to MAKE IT’S OWN FOOD.
What is a heterotroph?
An organism that must utilize another organism for food/ energy.
What is the ultimate source of energy?
Sun
What is an example of an autotroph?
Trees, Grass, etc.
What is an example of a heterotroph?
Bears, Humans, etc.
What does ADP mean?
Adenosine Diphosphate (2 phosphates)
What does ATP mean?
Adenosine Triphosphate (3 or more phosphates)
What is the formula for photosynthesis?
6 CO2+ 6 H2O –(with sunlight)–> C6 H12 O6 + 6 O2
What is the formula for cellular respiration?
C6 H12 O6 + 6 O2 –> 6 CO2+ 6 H2O (+ ATP)
What is pigment?
Light absorbing molecule
What is the main pigment in photosynthesis?
Green (Chlorophyll)
Where is the chlorophyll found?
Chlorophyll is found in plants in the thylakoid.
Where do light- dependent reactions take place?
Thylakoid membrane (chloroplast)
Where do light- independent reactions take place?
Storma (chloroplast)
Photolysis does what?
Turns H2O into H+O
What is the formula for light dependent reactions?
ADP + NADP + H2O + Light –> O + ATP + NADPH (I just have H2O + light –> H + O + ATP)
What is the formula for light independent reactions?
ATP + NADPH –> Glucose + ADP + NADP (I just have 6CO2 + H –> C6 H12 O6)
What would happen to the amount of sugars produced by the plants if the amount of CO2 available was reduced?
The amount of sugars would decrease. This is because in the equation for photosynthesis, CO2 is a reactant. Without CO2, photosynthesis could not take place and there would be no sugars made.
Explain how each of the following affects the rate of photosynthesis: CO2, light, water, temperature, and wavelength of light.
CO2: reactant of photosynthesis formula, process cannot happen without it
Light: used to split water in photosynthesis
Water: reactant of photosynthesis formula, process cannot happen without it
Temperature: can kill a plant if it is too severe
Wavelength of light: (idk but) determines what colors are absorbed or reflected by the plant
In what type of organism does cellular respiration occur?
Autotrophs (all eukaryotes and some prokaryotes) **It does occur in heteotrophs!
What is aerobic?
Uses Oxygen to grow
What is anaerobic?
Does not use Oxygen to grow
