Answer #1

DIFFERENCE BETWEEN GAMETOPHYTES AND SPOROPHYTES

GAMTEOPHYTES

SPOROPHYTES
  1. It is haploid in phase of the life cycle

It is diploid in phase of the life cycle
  1. It forms gametes

It forms spores
  1. Growth of meiospore produces gametophyte

Growth of zygote produces sporophyte
  1. It produces one set genome or one set of chromosome

It produces two sets of genome or two sets of chromosoms
  1. Gametes are forms directly or through mitosis

Spores are forms after meiosis

How are the gametophytes of a pine tree different from a fern gametophyte? Gymnosperm gametophytes are microscopic and completely dependent on the sporophyte for nutrition. The gametophyte is always surrounded by sporophyte tissue. The fern gametophyte is a completely independent stage of the life cycle, though typically smaller than the sporophyte. Fern gametophytes produce spores, while gymnosperm gametophytes produce eggs and pollen. Gymnosperm gametophytes consist of the male and female cones, while the fern gametophyte is a physically separated structure...

Which of the following is true of the life cycle of mosses? The growing embryo gives rise to the gametophyte. The haploid generation grows on the sporophyte generation.
