Where does germination of pollen grain occur in flowering plants?
On the stigma.
Where does germination of the pollen grain occur in flowering plants?
On the stigma.
Why used the mature pollen grain in pollen germination experiment?
this is because premature pollen grain do not contain the sperm cell for fertilization. only the generative nucleus in mature pollen grain will divide mitosisly to form sperm cell for fertilization
When a pollen grain joins an ovum?
A polln grain after germination sends a pollen tube in the ovule to release male gametes near the egg cell or ovum.
When a pollen grain joins with an ovum?
A polln grain after germination sends a pollen tube in the ovule to release male gametes near the egg cell or ovum.
What is the difference between fertilisation and germination?
fertilisationis when the pollen grain joins the ovum germinationis when a seed starts to grow in to a new plant
What is the difference between germination and pollination?
Pollination occurs when pollen reaches the pistil (female parts) of the flower. Fertilization occurs when the sperm cells of the flower fuses with the egg. Germination happens when the conditions are right the plant embryo germinates and begins to develop into a young plant. It is the only stage that does not include fertilization. Pollination is the first step fertilization the second and germination the third and final step.
How do seeds Reproduction?
it depends on gymnosperm (naked seed) or angiosperm (flowering plant) this is the angiosperm - Another germination event during the life cycle of gymnosperms and flowering plants is the germination of a pollen grain after pollination. Like seeds, pollen grains are severely dehydrated before being released to facilitate their dispersal from one plant to another. They consist of a protective coat containing several cells (up to 8 in gymnosperms, 2-3 in flowering plants). One of these cells is a tube cell. Once the pollen grain lands on the stigma of a receptive flower (or a female cone in gymnosperms), it takes up water and germinates. Pollen germination is facilitated by hydration on the stigma, as well as the structure and physiology of the stigma and style.[1] Pollen can also be induced to germinate in vitro (in a petri dish or test tube).[3][4] During germination, the tube cell elongates into a pollen tube. In the flower, the pollen tube then grows towards the ovule where it discharges the sperm produced in the pollen grain for fertilization. The germinated pollen grain with its two sperm cells is the mature male microgametophyte of these plants.[1
Why germination of cms pollen is low?
Cytoplasmic male sterile pollen is generally devoid of metabolic activities hence not capable of germination.
Do Dicot have pollen grain?
yes Dicot have pollen grain and in Dicots pollen grain possess 3 germ pores
What does pollen filter do?
pollentube helps in germination
What does a plant needs for germination?
A Stamen- to release pollen A Stigma- to receive pollen
