Total questions: 6
Worksheet time: 6mins
Double fertilization is a _______X_______ between one sperm cell (n) with an egg cell (n) to form __________Y________ . The other sperm cell (n) fuses with two polar nuclei to form __________Z________ .
X = fusion; Y = haploid zygote(n); Z = diploid endosperm (2n)
X = fusion; Y = diploid zygote (2n); triploid endosperm (3N)
X = diffusion; Y = haploid zygote(n); Z = diploid endosperm (2n)
X = diffusion; Y = diploid zygote (2n); triploid endosperm (3N)
List the female reproductive ORGANS in plant.
ovary
style
stigma
stamen
The male reproductive ORGANS in plant are anther and (a) .
This figure shows a mature pollen grain. Name parts A, B and C.
A = pit; B = pollen tube nucleus; C = generative nucleus
A = pollen tube nucleus; B = generative nucleus; C = pit
A = generative nucleus; B = pollen tube nucleus; C = pit
The generative nucleus divides by mitosis to form two male gametes.
Yes, it is.
No, it isn't.
After a pollen grain lands on a compatible stigma, a pollen tube nucleus is stimulated to germinate and then a pollen tube grows.
Yes, it is.
No, it isn't.
