Why gymnosperms are called as Heterosporous?

Why gymnosperms are called as Heterosporous?

Spores are the reproductive cells that are unicellular and are capable of developing into new whole organisms. Homosporous plants produce only a single type of spores while heterosporous plants generate two different kinds of spores. Gymnosperms are heterosporous in nature and produce both male and female cones.

Why angiosperms are called heterosporous?

Because the two spores produce different types of gameotphytes, They are called heterosporous, a feature found only in a few species of ferns, , and all of the seed plants (i.e., gymnosperms and angiosperms).

Are angiosperms are heterosporous?

As with gymnosperms, angiosperms are heterosporous. Therefore, they generate microspores, which will produce pollen grains as the male gametophytes, and megaspores, which will form an ovule that contains female gametophytes.Jun 8, 2022

Are angiosperms Homosporous or heterosporous?

Answer and Explanation: Flower plants are heterosporous, meaning that they produce two different types of spores.

Gymnosperms are heterosporous. The microspores and megaspores give rise to male and female gametophytes respectively. The spores produced are of different types and morphologically dissimilar.

Are all angiosperms heterosporous?

Gymnosperms are heterosporous in nature and produce both male and female cones.

Do gymnosperms have heterosporous?

Like all seed plants, gymnosperms are heterosporous. The sporangia that generate the male microspores and female megaspores are usually borne on separate cones.
