Select the correct statement about plant life cycles.

a) meiosis in plant life cycles is a sexual process, producing gametes.
b) over evolutionary time, the sporophyte has replaced the gametophyte in plant life cycles.
c) at some point in the life cycle of all plants, the sporophyte is dependent on its gametophyte parent.

The right answer is A.

Meiosis is an important process in many organisms:

In angiosperms, plants with flowers, meiosis occurs for the production of cells of pollen grains (gametes, haploid cells).

In animals, meiosis is important because it is the mechanism of gametogenesis that produces eggs (oogenesis) and sperm (spermatogenesis).

In the fungi, meiosis produces spores, which by mitosis will give a haploid generation.

i think a) betsy can donate only blood to mark is correct because, mark and betsy have the same blood type. whereas nobody else has b+ blood so betsy can't donate to them.
