In these figures, two life cycles are described. Mark the correct option.

How many of the given statements (I-IV) about different plant groups are not correct?
I- Majority of pteridophytes are heterosporous.
II - Pollination in gymnosperms is direct and anemophilous.
III - The first stage of moss gametophyte is leafy stage, which develops directly from spore.
IV - In flowering plants, endosperm is triploid and is pre-fertilisation structure.

The most common type of life cycle in algae is

Which pattern of life cycle is exhibited in bryophyte and pteridophyte?

The life cycle pattern of spermatophytes is:

In Spirogyra, meiosis occurs during

Zygote of an organism developed after syngamy undergoes meiosis to form haploid spores, which divide mitotically and form the gametophyte. The organism must have  ___________________________________life cycle.

Spirogyra is a sexually reproducing alga in which vegetative thallus is haploid. In Spirogyra, meiosis:

Zygotic meiosis is characterstic of
