Reproduction In Plants

Step 1: Understanding the Question.
We are asked to match the items in Column I with their appropriate pairs in Column II. Let's look at the connections between the items.

Step 2: Analyzing the Options.
(A) (p-iii), (q-iv), (r-i), (s-ii): Correct — Summer relates to medicinal properties, butterflies are involved in insect pollination, mango is an efficient carrier of seeds, and flowers are fruit-producing flowers.
(B) (p-iv), (q-iii), (r-i), (s-iii): This is incorrect, as the pairings do not make sense.
(C) (p-iii), (q-iii), (r-iv), (s-i): This doesn't fit because the pairings do not align with their correct meanings.
(D) (p-iii), (q-i), (r-ii), (s-iv): Again, this doesn't match as expected.

Step 3: Conclusion.
The correct answer is (A) (p-iii), (q-iv), (r-i), (s-ii), as it correctly pairs the items based on their meanings.

Step 1: Understanding the Question.
This question asks which plant family produces pollen that cannot remain viable for months.

Step 2: Analyzing the Options.
(A) Pine: Pine pollen can remain viable for extended periods.
(B) Willow: Willow pollen also tends to remain viable for a longer duration.
(C) Solanaceae: Correct — Solanaceae family pollen does not remain viable for as long as other types.
(D) None: This is incorrect since Solanaceae is the correct answer.

Step 3: Conclusion.
The correct answer is (C) Solanaceae, as this plant family’s pollen does not remain viable for months.
