What is the main difference between double fertilization and alternation of generations life cycles in plants ?
In this case, the double fertilization occurs when two sperm cells fertilize only one egg cell. One sperm will form the zygote while the other one will form the endosperm by fusing with the two polar nuclei. On the other hand, the alternation of generations consist in alternation of two stages, one sexually haploid and the second one an asexual diploid. In double fertilization, the haploid sexual is the main stage while in alternation of generations both haploid and diploid stages have importance.

Do all plants go through alternation of generations life cycles ? Do all plants go through double fertilization ?
What do plants go through alternation of generations life cycles ? In other words, what is the purpose of this process ?
Compare and contrast the life cycles of humans and plants (alternation of generations). For each of the following aspects of the life cycles, determine whether the two life cycles are similar or different. If they are different, describe the difference. If they are similar, describe how they are similar. (Hint: look at the figures in your book or the class slides showing the life cycles as you answer this question.) a) the process that produces gametes b) the ploidy of...

O double fertilization alternation of generations O production of pollen O a reduced and nutritionally dependent gametophyte O seeds Question 23 3 pts Mitotic cell division in eukaryotes is roughly analogous to which process in prokaryotes? O Conjugation O Meiotic cell division Binary fission O DNA Replication

In what way was the seed an important adaptation in the evolution of plants? Explain the difference between pollination and fertilization. How much time elapses between these two processes in pine? 1. 2. 3. Outline the main events of the pine life cycle. Where are the gametes produced? Where are the spores produced? What generations are independent? At what stage does dispersal occur? Make a table like the one below where you compare reproduction, dispersal, and protection of the zygote...
Which of the following is/are HAPLOID (1N) in the alternation of generations lifecycle in plants? A Zygote B. Spores Sporophyte D. Gametes
In the alternation of generations lifecycle in plants... A. There is a diploid multicellular phase (sporophyte) and haploid multicellular phase (gametophyte) The zygote undergoes mitosis to form a multicellular embryo. Meiosis and syngamy both occur.
