DNA content in differentiated antipodal cells has been determined by a cytophotometric analysis; in the case of a mature embryo sac, the ploidy of antipodal cells varied from 8 to 32C.

You have 46 chromosomes in your somatic cells and 23 chromosomes in your gametes. c. Offspring differ from their parents because mutations occur during sexual reproduction.

diploid

The ploidy level of the plant is diploid. Hence, the ploidy level of nucellus is 2n. MMC is a microspore mother cell, also known as meiocyte which undergoes meiotic division and produces female gametes. So, it’s ploidy is 2n.

MMC(produces haploid gametophytes by meiotic division) Since, it undergoes meiotic division its ploidy is 2n. The integument and funicle are also diploid in nature. 3)Female gametophytes also called as embryo sac(produced by meiotic division from Megaspore mother cell) has ploidy n.

it is diploid. Sporogenous tissue is available both in anther and ovule. Recollect that in plants all cells are diploid aside from dust grains and female gametophyte (incipient organism sac) which are haploid,and after treatment endosperm is shaped which is triploid.

Gametes develop in the multicellular haploid gametophyte (from the Greek phyton, “plant”). Fertilization gives rise to a multicellular diploid sporophyte, which produces haploid spores via meiosis. This type of life cycle is called a haplodiplontic life cycle (Figure 20.1).

Taproots and fibrous roots are the two main types of root systems.

A tap root system has a single main root that grows down. An example of a tap root system is a carrot. Grasses such as wheat, rice, and corn are examples of fibrous root systems. Fibrous root systems are found in monocots; tap root systems are found in dicots.
