Question

Which of the following is the first cell of female gametophyte generation in angiosperms?
A. Megaspore mother cell
B. Microspore mother cell
C. Functional megaspore
D. Egg cell

Answer 1

Hint: A megaspore mother cell, or megasporocyte, is a diploid cell in plants wherein meiosis will happen, bringing about the creation of four haploid megaspores. At any rate, one of the spores forms into haploid female gametophytes (megagametophytes).

Complete answer:
The mother cell(MMC) of megasporangium goes through meiosis and structures megaspore quadruplicate out of which one megaspore is functional. The functional megaspores from mitotically into the undeveloped organism sac for example the female gametophyte. In this way, the functional megaspore fills in as the primary cell of the female gametophyte.
-Microspore is a diploid cell in plants that partitions by meiosis to offer ascent to four haploid microspores.
-The ovaries produce the egg cells called the ova or oocytes. The oocytes are then moved to the fallopian tube where fertilization by a sperm may happen.
-A megaspore mother cell, or megasporocyte, is a diploid cell in plants wherein meiosis will happen, bringing about the creation of four haploid megaspores. At any rate, one of the spores forms into haploid female gametophytes (megagametophytes).
Hence, the right answer is choice C.

Note: In angiosperms or blooming plants, the megasporocyte produces a megaspore. This megaspore forms into an incipient organism sac. This is done through two unmistakable cycles megasporogenesis (arrangement of the megaspore in the nucellus, or megasporangium), and megagametogenesis (improvement of the megaspore into the undeveloped organism sac, or megagametophyte). In blossoming plants microspore mother cells are shaped inside the dust sacs of the anthers by mitosis, the microspores they produce form into dust grains.
