What do you call an organism that is able to produce its own food using sunlight?
Phototrophs
What do you call the region between the inner and outer membranes of a chloroplast?
Intermembrane space
What do you call the interconnected sacs which serve as the site for light-dependent reactions in the chloroplast?
thylakoids
What do you call the dense fluid located in the inner space of the chloroplast?
Stroma
When grana are stacked together, they are collectively called thylakoids. True or false?
False, it should be the other way around. A single stack of thylakoids is called granum, while multiple stacks are called grana
Plants appear green because green light is less efficiently absorbed by a specific pigment in plant leaves. What is this pigment called, and where is it found?
Chlorophyll - thylakoid membranes
Chlorophyll a is the main pigment in photosynthesis as it directly participates in chemical reactions during the calvin cycle. True or false?
False. According to the material, chlorophyll a participates directly in LIGHT REACTIONS, not dark reactions aka the calvin cycle
What do you call the process where water is oxidized and carbon dioxide is reduced?
Redox. After photosynthesis, carbon dioxide is reduced and gains hydrogen, resulting in glucose. On the other hand, water loses hydrogen, and that results in oxygen.
This reaction, such as photosynthesis, is a type of reaction that requires an input of energy.
Endergonic reactions require an input of energy. For example, photosynthesis requires an input of light energy from the sun
What do you call the passive membrane transport that allows CO2 and O2 to enter and exit through the stomata?
Diffusion. Gasses move by simply diffusing through open stomata, making it very efficient
Which pigment is considered the "key light-capturing pigment" that dominates the process and is the primary electron donor during photosynthesis?
Chlorophyll a
If you were trying to look for the specific interior tissue of a leaf where the majority of chloroplasts are found, which ground tissue should you be looking at?
Mesophylls. These are ground tissues which if we recall, are generally responsible for plant metabolism. That’s why chloroplasts are highly concentrated here, particularly in the mesophylls
Which pigment responsible for the plant colors yellow, orange, and red also assists in photosynthesis by harvesting light and serving as a protective agent?
Carotenoids. They absorb blue-green light, so they reflect longer wavelengths on the warmer end of the spectrum. They also help chlorophyll a by harvesting light energy, optimizing photosynthesis
What are the reactants of photosynthesis?
6 carbon dioxide molecules and 6 water molecules
What are the products of photosynthesis?
1 glucose molecule and 6 oxygen molecules
