Question

What molecule enables plants to harvest light? ATP Chlorophyll Glucose Rubisco why is so much water needed for photosynthesis? Because it is used in the reaction CO_2 + H_2O rightarrow Because plants must keep stomata open to get CO_2 Because water provides the energy to make sugar Because plants must keep cool for photosynthesis t Which two carbon molecules does the plant use for carbon 3-C sugar molecule (such as G3P) and cellulose Sucrose and 3-C sugar molecule Starch and cellulose Sucrose and starch

Explanation / Answer

Q 16. Chlorophyll.

Chloroplasts (organelle found in plants and algae) are bounded by a double membrane, which have an outer and inner membrane. The inner space is called “stroma,” which contains concentrated enzymes and disc-like sacs called “thylakoids.” The lump of thylakoids is called “granum.” Thylakoid membrane contains the pigments (such as chlorophyll) which capture the solar energy and stroma contains the enzymes which are essential for photosynthesis.

Q 17. b. Because plants must keep stomata open to get CO2 into leaves, so water diffuses out as a consequence.

So much water is needed for photosynthesis because plants must keep stomata open to get CO2 into leaves, so water diffuses out as a consequence.

Q 18. Sucrose and starch

Sucrose and starch are the main forms of energy storage in plant leaves. Starch is the structural form, not storage form.
