What is the function of pollination?

Pollination is an essential part of plant reproduction. Pollen from a flower's anthers (the male part of the plant) rubs or drops onto a pollinator. The pollinator then take this pollen to another flower, where the pollen sticks to the stigma (the female part). The fertilized flower later yields fruit and seeds.


How many pollen grains does 10 microspores make?

40 pollen grains

What is Ovum and ovule?

As nouns the difference between ovum and ovule

is that ovum is (label) the female gamete in animals; the egg cell while ovule is (botany) the structure in a plant that develops into a seed after fertilization; the megasporangium of a seed plant with its enclosing integuments.


How many microspore mother cells will give rise to 256 microspores after reduction?

64 MMC


What is the fate of the ovules and ovary in a flower after fertilization?

After fertilization occurs, each ovule develops into a seed. Each seed contains a tiny, undeveloped plant called an embryo. The ovary surrounding the ovules develops into a fruit that contains one or more seeds.


Do ovules become seeds?

In the typical flowering plant, or angiosperm, seeds are formed from bodies called ovules contained in the ovary, or basal part of the female plant structure, the pistil.


What is fertilization plant?

In plants, fertilization is a process of sexual reproduction, which occurs after pollination and germination. Fertilization can be defined as the fusion of the male gametes (pollen) with the female gametes (ovum) to form a diploid zygote. It is a physicochemical process which occurs after the pollination of the carpel.


Which is the reproductive part of a plant?

You know that the flowers are the reproductive parts of a plant. Stamens are the male reproductive part and pistil is the female reproductive part (Fig. 12.9).


Is papaya monoecious or dioecious?

dioecious


What is triple fusion?

Definition of triple fusion

: the fusion involving two polar nuclei and a sperm nucleus that occurs in double fertilization in a seed plant and results in the formation of the endosperm.


Is present in unisexual flower Mcq?

Solution. Androecium or gynoecium is present in unisexual flower.


What is the difference between microgametogenesis and megagametogenesis?

The difference between microgametogenesis and megagametogenesis. is that "microgametogenesis" is the gametogenesis of microgametes and "megagametogenesis" is the development of a megaspore into an embryo sac. Microsporogenesis involves the formation of microspores from microspore mother cells by meiotic division.


Which one is a female gametophyte?

Explanation: The embryo sac represents the female gametophyte.


How is fertilization brought about in a flower?

From the anther the pollen grains are first deposited on the pistil's surface, the stigma. There they germinate and form pollen tubes, which grow downward through the style toward the ovules. Fertilization occurs as a sperm cell in a pollen tube fuses with the egg cell of an ovule, resulting in a plant embryo.


Which of the following is not a part of flower Mcq?

Answer. Explanation: Colourful bracts are not a part of the flower.


What is Monoecious plant?

Monecious plants have both male and female flowers rather that perfect flowers. Corn (maize) is a good example of a monecious plant species. It has two types of flowers that develop at different parts of the plant. The male flower forms at the top of the plant and is called the tassle.


Which part of the flower becomes the seed Mcq?

The (Male organ part) of a flower is called the (Stamen) and the (Female organ part) of a flower is called (Carpel). These Pollen Grains help in making (Male Gametes) of the plant and are present in Anther. The (Male Gametes) fertilize the (Female Gametes). The fertilized (Egg cells) grow in Ovules and become Seeds.


What is sexual reproduction in plants with diagram?

Process of sexual reproduction: The pollen grains are deposited on the stigma. They germinate on the stigma to produce a pollen tube. The generative cell moves into the pollen tube. It undergoes mitotic division to produce two male gametes.
