Question

What plant material is best suited for studying mitosis is class room?

• A. Anther
• B. Piece of cork
• C. Root tips
• D. Shoot apex

Answer 1

The correct option is A Anther

A transverse section of the anther reveals four areas of tissue capable of producing spores. These tissues are composed of microsporocytes, which are diploid cells capable of undergoing meiosis to form a tetrad (four joined cells) of haploid microspores. The microspores become pollen grains and may eventually separate. Each microspore (pollen grain) divides mitotically to form a two-celled microgametophyte; one cell is a tube cell (the cell that develops into a pollen tube), and the other is a generative cell, which will give rise to two sperm as a result of a further mitotic division. .Pollen grains can also be induced to germinate in a synthetic medium. Sucrose is used as a pollination solution(Medium). Sucrose induces the pollen germination & tube growth in vitro. This can helps students to observe the divisions in anthers.

So, the correct option is 'anther'.
