Q. What does moving pollen do for plants?
Pollination is the process of moving the pollen from the male components of a plant or flower to the female parts. This fertilizes the female reproductive cells so that a fruit or seeds will develop.
Q. What does the pollen do?
Pollen grains are, in essence, plant sperm. Or perhaps more technically, sperm sedans. Inside, they contain the male portion of DNA needed for plant reproduction.
Q. What characteristics make pollen more attractive?
Pollinators use their eyes and antennae (sense of smell) to locate flowers (usually ones with bright colors that smell). Wings or legs allow pollinators to move easily from flower to flower, taking pollen along with them. Many bees are also great pollinators because they have hairy bodies.
Q. Why does Exine of the pollen grain needs to be hard?
Yes exine should be hard because it protects pollen grain (by which pollen grain develops normally) from severe conditions. It is the outermost layer made up of sporopollenin which protects pollen grain from harsh environmental conditions. Through germ pore pollen tube develops and comes out.
Q. How long do you think the pollen grain retain viability?
30 minutes
Q. What is function of germ pore in pollen?
A germ pore is a small pore in the outer wall of the fungal pore from which the germ tube comes out. > The germ pore plays an important function in plant fertilization. It assists in the creation of pollen tube and releases male gametes during fertilisation.
Q. What does germ pore do?
A germ pore is a small pore in the fungal pore’s outer wall from which the germ tube then exits at germination. Germ pore plays an essential part in the fertilization of plants. It helps in pollen tube formation and releases the male gamete during fertilization.
Q. Where is germ pore present?
A germ pore is a small pore in the outer wall of a fungal spore through which the germ tube exits upon germination. It can be apical or eccentric in its location, and, on light microscopy, may be visualized as a lighter coloured area on the cell wall.
Q. How many germ pores in Uredospores are?
has uredospores of the usual appearance, globoid, with rather thin, pale yellow walls, echinulate, with about six scattered germ pores. The sori are yellow and inconspicuous.
