b Sperm cells are carried by the wind to egg cells.
c Diploid and haploid phases alternate.
d Sporophytes are formed by meiosis.

Answer 1

Answer:

• The correct option is option c.) Diploid and haploid phases alternate.

Explanation:

• In every plant life cycles the alternation of generation takes place, and the haploid and diploid phases alternates.

• It takes place in every Division of Kingdom Plantae, that is in Thallophyta, Bryophyta, Pteridophyta, Gymnosperms, and Angiosperms.

• The seed producing plants belongs to Division Spermophyta which includes all seed bearing plants which comes under Gymnosperms and Angiosperms.

• Sperm cells or pollen grains are taken by wind for fertilization only in Angiospermic plants pollinated by winds, such type of pollination are called as Anemophilly.
