File this one under "confusing plant terminology." Both a plant's stoma and its stroma are important in photosynthesis. What's the difference between stoma and stroma?
a) Stoma is the singular of stomata, the gas exchange pores in the leaf of the plant, while stroma is the fluid that fills the inner space of a chloroplast.
b) Stoma is the singular of stomata, the fluid that fills the inner space of a chloroplast, while stroma are the gas exchange pores in the leaf of the plant.
c) Stoma is the singular of stomata, the gas exchange pores in the leaf of the plant, while stroma is the disk-like membranous sac in which the light-reactions of photosynthesis take place.
d) Stoma refers to the non-sexual cells of a plant, while stroma is the fluid that fills the inner space of a chloroplast.
e) Stoma is the fluid that fills the inner space of a chloroplast, while stroma is a stack of disk-like thylakoids.
Ans: a) Stoma is the singular of stomata, the gas exchange pores in the leaf of the plant, while stroma is the fluid that fills the inner space of a chloroplast.
