Random Recall
Why are plants green?
Chlorophyll reflects green light
What is the ultimate source of all energy?
The Sun
Molecules that are often lipids and absorb light from the sun are called?
Pigments
Water is split, energy is stored in ATP and NADPH, and oxygen is released during...
Light-Dependent Reactions
Four main factors that affect the rate of photosynthesis
Light, Water, CO2, and Temperature
What does the endosymbiotic theory state?
mitochondria and chloroplasts were originally free living bacteria that were engulfed by another ancestral prokaryotic cell, creating the first eukaryotic cell
What is the difference between how plants and animals acquire energy?
plants are autotrophs, they capture light energy from the sun
animals are heterotrophs, they consume other plants and animals for energy
The primary pigment contained in chloroplasts is...
Chlorophyll
What is another name for light independent (dark) reactions
The calvin cycle
Would an increase in the amount of carbon dioxide would increase the rate of photosynthesis?
Yes, up to a certain point
What membrane bound organelle contains the genome?
Nucleus
The process by which energy from sunlight is changed into chemical energy and stored as sugar is called?
Photosynthesis
What two organelles are referenced in the endosymbiotic theory?
Mitochondria and Chloroplasts
Where does the initial stage of photosynthesis occur during light-dependent reactions?
Thylakoid membranes of chloroplasts
Describe the curve of a graph showing the effect of temperature on the rate of photosynthesis.
Where is the optimal temperature?
Bell Curve
At the peak of the curve
What is transpiration?
The process of losing water in the form of vapor through stomata
Glucose made in photosynthesis can be used to form (4)
Complex carbohydrates
Lipids
Proteins
Nucleic Acids
Where does photosynthesis occur?
The chloroplast
Carbon dioxide and energy in ATP and NADPH form glucose during...
Light-independent (dark) reactions
Calvin Cycle
Why is light energy necessary for plants to photosynthesize?
The light energy is used to split the water molecules (photolysis) and form ATP and NADPH
Where is transpiration most frequent?
Warm and Dry conditions
Which of the following is the balanced equation for photosynthesis?
6 CO2 + 6 H2O → C6H12O6 + 6O2
Carbon Dioxide + Water + Light Energy = Glucose and Oxygen
How 4 things do prokaryotic and eukaryotic cells have in common?
Plasma membrane, ribosomes, cytoplasm, and DNA
During _________________ reactions, NADP+ is converted to NADPH when it accepts an electron.
Light-dependent
How do you think scientists may measure the rate of photosynthesis in a plant?
Monitoring gas exchange of CO2 and O2
