<span>The answer is Haploid spores germinate to give rise to protonema, which later develops into a sporophyte.</span>
A protonema (plural: protonemata) is a
thread-like chain of cells that forms the earliest stage (the haploid phase) of a bryophyte life
cycle..
<span>A haploid gametophyte ( each of whose cells contains a fixed number of
unpaired </span>chromosomes) gives rise to a <span>diploid sporophyte</span>,.
Gametophytes produce haploid sperm and eggs which fuse to form diploid zygotes
that grow into sporophytes.
1) Enzyme activity
2) Cell to cell recognition
3) Cell signalling
4) Transport Materials.
Hope this helps! :)

Explanation:
they drop leaves and almost hibernate for the winter, like some animals!
Answer:
Explanation:
Lethal mutations are mutations that are deleterious, its presence in an individual brings about the death of such individual.
Insertion or deletion this a mutation caused by the addition or deletion of a nitrogenous base leading to a shift in the reading frame and a formation of new bases sequence.
Indel mutations can be beneficial at times resulting into variations that is important in an individual. This variation can be explored and use for research.
