In a plant’s life cycle, how many sporophyte generations occur between one gametophyte generation and the next time that eggs and sperm are produced?

Ans.

Plants that show distinct asexual diploid and sexual haploid stages show alternation of generations. In these plants, the sexual haploid stage (or multi-cellular gametophyte generation), with n number of chromosomes alternates with asexual diploid stage (multi-cellular sporophyte generation), with 2n chromosomes.  

The gametophyte produces gametes (eggs and sperms) that forms zygote and develop into microsporophyte that develops into sporophytes. After maturation, sporophytes produces spores that form gametophytes and again formation of gametes (eggs and sperms) will take place.

Hence, 'one sporophyte generation would occur between the one gametophyte generation and production of eggs and sperms in next steps.'

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
