  • Question 1/5
    1 / -0.33
    Vegetative propagation in Bryophyllum is done with the help of _______?
    Solutions

    Vegetative propagation is an asexual reproduction in which new plants are obtained from plant parts such as the leaves, stem and root without the help of reproductive organ the bryophyllum leaf has many buds on its margins. New plant arises from these buds when a leaf falls in wet soil. Hence, option B is correct.

  • Question 2/5

    The process of transfer of pollen grains from the anther to the stigma is called?
    Solutions

    Pollination is the act of transferring pollen grains from the male anther of a flower to the female stigma. Once it occurs, fertilized flowers produce seeds, pollination through wind is an example. Budding is a grafting technique. in this budding process, a new organism is developed from a tiny part of the parent's body. In binary fission, an organism duplicates genetic material or DNA then divides into two parts with each new organism receiving one copy of DNA.

  • Question 3/5

    Functional megaspore in an angiosperm develops into an?
    Solutions

     In angiosperms or flowering plants, the mega sporocyte produces a megaspore that develops into an embryo sac through two distinct processes megasporogenesis (formation of the megaspore in the nucellus, or megasporangium), and mega gametogenesis (development of the megaspore into the embryo sac, or megagametophyte).

  • Question 4/5
    1 / -0.33
    Which part of the flower produces pollen?
    Solutions

    The Apther is also known as anther. It is a pollen-producing part of a flower. The stamen consists of anther where pollen is produced, anther is a male part of a flower. The final step involves another cell division, that creates two cells within one pollen grain.

  • Question 5/5
    1 / -0.33
    Which of the following is the male reproductive organ in plants?
    Solutions

    The stamen is known as the reproductive organ of the plants. It contains a pollen sac which is known as an anther and a long supporting filament. It holds the anther in position, making the pollen present for dispersal by wind, birds, or insects. Hence, option B is correct.
