a fruit is most commonly _______?
A. modified root
B. a mature female gametophyte
c. mature ovary
d. a thickened style
e. enlarged ovule
Modified root
A thickened style
A mature ovary
a mature female gametophyte
a thickened style
To determine the correct answer, we need to understand the botanical definition of a fruit. A fruit is the mature ovary of a flowering plant, typically containing seeds. With this knowledge, we can evaluate the options:
A. Modified root: This is not the correct answer since a fruit is not a modified root.
B. Mature female gametophyte: This is incorrect because a fruit is not a gametophyte (the female gametophyte is the embryo sac, which is not the same as a fruit).
C. Mature ovary: This is the correct answer. A fruit is most commonly a mature ovary of a flower.
D. Thickened style: This is not the correct answer. The style is a part of the female reproductive structure of a flower, but it does not describe a fruit.
E. Enlarged ovule: This is not the correct answer. While the ovule becomes a seed within the fruit, the entire fruit is not an enlarged ovule.
Therefore, the correct answer is C. A fruit is most commonly a mature ovary.
