Sexual reproduction requires recognition between the male and female gametes. In flowering plants, the immobile sperms are delivered to the ovule-enclosed female gametophyte by guided pollen tube growth. Although the female gametophyte-secreted peptides have been identified to be the chemotactic attractan...
In flowering plants, male and female gametesnare produced in the anther and ovule, respectively.nMale gametes are contained withinnpollen grains, which are released from thenanthers at anthesis. After a pollen grain landsnon the stigma, male gametes are delivered tonthe ovule via the pollen ...
Plants, like most organisms, contain both male and female gametes for reproduction, however, unlike most organisms, the male and female parts are found on the same plant. What are the two types of gametes? The two types of gametes are the male gamete and the female gamete. What is the ...
This difference in the behavior of male and female gametes had been quite unexpected. It proved to be the first genetic counterpart to Wilson's findings on the spermatozoa of insects, which differed in their chromosome constitution, whereas the eggs were all the same in this respect (Chapter 1...
In flowering plants, two reproductive cells are found namely, a male gamete and a female gamete which are fused to produce a zygote which is further divided several times to develop into an entire plant again.Answer and Explanation: In flowering plants, the male gametophyte is a male ...
The full range of gene expression leading to male gamete formation in flowering plants begins with determination of the stamen whorl in flower development and ends with release of mature sperm into the embryo sac near the egg and central cell. In this review we focus on events within the anthe...
The correct Answer is:B in angiosperms, the male gametes are carried by the pollen tube and such type of fertilisation or fusion of male and female gametes or syngamy is called siphonogamy. It was discovered by Strasburger (1884). Show More ...
Answer to: Summarize the process by which the male and female gametes are brought together. Why is this process referred to as double...
Fusion of one male gamete with egg and other of the same pollen tube with two polar nuclei is ATriple fusion BVegetative fertilization CDouble fertilization DParthenogenesis.Submit The fusion of male and female gametes in the embryo sac is called ATriple fusion BSyngamy CDouble fertilisation DZoo...
In subject area:Immunology and Microbiology The male gametophyte, pollen, consists of three cells that include two gametic sperm cells and a vegetative cell responsible for delivering the sperm cells to the female gametes. From:Transgenerational Epigenetics,2014 ...
