Emasculation is the removal of anthers from a bisexual flower. It is done to prevent self-pollination and cross-pollinate plants to combine... View Article
Both, vegetative reproduction and apomixis are asexual methods of reproduction and produce identical progeny to the parent plant. Also Check:... View Article
Amphimixis refers to sexual reproduction, where the fusion of two gametes takes place. Apomixis is asexual reproduction, which occurs without... View Article
Apomictic seeds are produced without fertilisation. Hybrid crop cultivation produces more yield and crops with desirable traits. Hybrid seeds... View Article
Apomixis is the formation of seeds without fertilisation. Apomixis is commercially used to produce seed in hybrid plants so that they need not be... View Article
Human gametes are haploid as they are formed by meiosis during gametogenesis. Haploid gametes ensure that after fusion of male and female... View Article
Synergids are produced by the mitotic division in the haploid megaspore of a diploid plant. So synergids of a diploid plant are haploid. Also... View Article
The ovule is the megasporangium in the flowering plants. It contains an embryo sac, which is formed from the functional megaspore. The ovule is... View Article
Cotyledon is referred to as the embryonic leaf. It is present in seeds and stores food reserves. Angiosperms are divided into monocotyledons and... View Article
Synergids are a part of the egg apparatus of the embryo sac. The megaspore mother cell divides meiotically to give rise to megaspore tetrad. Out... View Article
The embryo sac is the female gametophyte of angiosperms. It is formed by the functional megaspore produced from the megaspore mother cells. The... View Article
Triple fusion refers to the fusion of three haploid nuclei at the time of fertilisation in the embryo sac. The fusion of the second male gamete... View Article
The micropyle is the small opening present at the tip where the integument does not cover the nucellus in the ovule. Pollen tube enters the ovule... View Article
Synergids are part of the egg apparatus and present at the micropylar end of the embryo sac. It helps in guiding pollen tubes in the ovule and... View Article
Humans are diploid organisms with 46 chromosomes (2n = 46). Eggs are produced by meiosis during oogenesis so they are haploid and contain 23... View Article
The integument is the outer protective envelope of an ovule. It is diploid in a diploid angiosperm. Integuments are present outside the nucellus.... View Article
Cotyledons store food reserves in the seed. It is also called an embryonic leaf. Monocotyledons contain a single cotyledon, which is also known... View Article
Synergids are present at the micropylar end. The egg apparatus contains two synergids and an egg cell. Synergids help in guiding the pollen tube... View Article
A small amount of androgens is produced in females also from adrenal glands and ovaries. The excess androgen may be due to tumours in the ovary... View Article
Yes. Sucrose is a non-reducing carbohydrate, as it does not contain any free anomeric carbon atom and cannot donate electrons to other molecules.... View Article
