Question
Pollen develops from the mitotic division of microspores. Given this information, to which specific stage in a heterosporous life cycle does pollen belong?
Solution
Pollen belongs to the gametophyte stage of a heterosporous life cycle. Here's the step-by-step explanation:
-
In a heterosporous life cycle, there are two types of spores produced: microspores and megaspores.
-
Microspores develop into male gametophytes, while megaspores develop into female gametophytes.
-
The question states that pollen develops from the mitotic division of microspores. This means that pollen is a product of microspores.
-
Since microspores develop into male gametophytes, and pollen is a product of microspores, it follows that pollen is part of the male gametophyte stage in a heterosporous life cycle.
So, the specific stage in a heterosporous life cycle that pollen belongs to is the male gametophyte stage.
