During Oogenesis,in human female, a primary oocyte produces four haploid cells. Out of these four haploid cells, only one is used in reproduction. Then
What happens to the other three haploid cells?

During Oogenesis,in human female, a primary oocyte produces four haploid cells. Out of these four haploid cells, only one is used in reproduction. Then What is the fate of the haploid cells used in reproduction?

During Oogenesis,in human female, a primary oocyte produces four haploid cells. Out of these four haploid cells, only one is used in reproduction. Then What is the significance if this type of meiotic division during oogenesis?

First haploid cell of female gametophyte is

Name the type of cell division which produce four haploid cells with new combination of characters from a diploid cells.

Read the following statements and find out the incorrect statements. a. Asexual reproduction is common among single celled organisms, and in plants and animals with relatively complex organisations. b. In yeast, the division is unequal and small buds are produced that remain attached initially to the parent cell which eventually gets separated and mature into new yeast organism (cells). c. Vegetative reproduction is also a type of asexual reproduction. d. While in animals and other simple organisms the term vegetative reproduction is used unambiguously, in plants, the term asexual reproduction is frequently used. e. Water hyacinth is also called 'Terror of Bengal.'

a mass m is suspended at one end of a spring and the other end of the spring is fimly fixed on the celling. if the mass is slightly depressed and released it will execute oscillation. if this system is completely immersed in water then what happens to the oscillation?

Read the following statements and find out the incorrect statements. a. Ovules generally differentiate a single megaspore mother cell (MMC) in the chalazal region of the nucellus. b. The MMC undergoes reduction division and produces four megaspores. c. In a majority of angiosperms, one of the megaspore is degenerated while the other three remains functional. d. The nucleus of the functional megaspore divides mitotically three times and form 2-nucleate, 4-nucleate and later 8-nucleate stages of the embryo sac. e. These mitotic division are strictly free nuclear, that is, nuclear division are immediately followed by cell wall formation.
