Flowering plants

Postby Elliott » Wed Mar 01, 2006 5:16 am

Is true that the ovules contain the microspore mother cell?, and the male gametophyte generation will form the generative and tube nuclei?

i think the secon' one is false what do u think???



Regarding plants:
1) the sporophyte undergoes mitosis to form haploid spores
2) reproduction of a flowering plant involves a megaspore and a microspore
3) megaspores are produced within ovules and becomes eggs
4) some plants dependon insects and birds for pollination
5) double fertilization refers to the production of a diploid zygote and a triploid endosperm nucleus

I'm positive 2,3,4, are true not sure about 1 and 5 i dont think sporophyte undergoes mitosis, and in number five i dont think double fertilization after the diploid zygote is a triploidendosperm

Sporophyte undergoes meiosis to produce haploid spores.
#5 is true I believe
