Can pollination in pea plants happen in three ways?
Pea flowers are self-pollinating. About two days before the flower even opens, the anthers at the top of the stamen, which are the male part, burst and release the pollen. This sticks onto the stigma and fertilizes the ovary - these are the female parts. In many flowering plants, the stigma will not accept pollen from the same plant and fertilization must occur through other means, such as insect pollination after the flower opens. For gardeners, self-pollination is an advantage as it means more than one type of pea can be grown close together, as cross-pollination will not occur.
How is wind pollinating a flower similar to an insect pollinating a flower?
They both produce pollen, therefore they must have anthers and since they both produce seeds they must have stigmasThe end results of wind pollination and insect pollination are the same, the plants are pollinated.Wind pollinated plants, which include the grasses and some trees, have either no flowers or very insignificant flowers because they have no need to attract insects. The anthers produce very large amounts of very small pollen grains which are then blown by the wind in the hope of hitting a stigma of the same variety of plant. This is the type of pollen which is the major cause of hay fever.Insect pollinated plants will have flowers, usually with nectar, to attract the insects and reward them with food. A bee's body is covered with fine hairs which become charged with static electricity as the insect flies so when it lands on the flower the pollen grains are actually attracted to the bee's body. When the bee goes to the next flower, some of this pollen is transferred to the flower's stigma. Pollen grains of insect-pollinated plants are much larger than those of wind-pollinated plants.
How long does the morning height remains as human height is 1 cm extra in the morning than the evening?
3 cm
Why are there a greater number of anthers than stigma?
One reason is the the pollen (from anthers) need to travel to the stigma - either on the wind or carried by insects. Many pollen grains will get lost enroute so lots more need to be produced.
Are east and west railway rails at a different height than north and south?
