a). thylakoids
b). guard cells
c). stomata
d). mesophyll cells​

Answer 1

d) Mesophyll cells is the answer

Answer 2

Closely packed structures in plastids that are responsible for photosynthesis are a)Thylakoids.

Explanation:

• In multicellular autotrophs the main cellular structures that allow photosynthesis to take place include chloroplasts, thylakoids, and chlorophyll.
• In plants photosynthesis takes place in chloroplasts, which contain the chlorophyll.
• Chloroplasts are surrounded by a double membrane and contain a third inner membrane called the thylakoid membrane that forms long folds within the organelle.
• Thylakoids are tiny compartments found inside of chloroplasts. Their role is to help absorb sunlight in order for photosynthesis to occur.
• They contain all of the chlorophyll that the plant has which in turn allows for the absorption of sunlight.
• These are the most important sites which house green pigment called chlorophyll.
• It is the collection of sacs which stack together to form thylakoids.
• These sacs are arranged in stacks called grana light energy is converted to chemical energy at grana.
