5. No Meiosis: In apomixis, the diploid cells (either the nucellar cell or the egg cell) do not undergo meiosis. Instead, they directly develop into seeds, maintaining the diploid chromosome number. Show More | ShareSave Class 12BIOLOGYSEXUAL REPRODUCTION IN FLOWERING PLANTS ...
(b) Mention any two methods which use the property of vegetative reproduction to produce new plants. (c) State any one advantage of this method. View Solution Leaf helps in vegetative propagation in View Solution Vegetative propagation in Mint occurs by View Solution ...
How does double fertilization occur in flowering plants? Are gametes sex cells or zygotes? What is meiosis? Why is it necessary for fertilization to occur in the outer third of the uterine tube? How is a zygote formed? What type of reproduction is used for cloning?
In plants chloroplasts engage in contact sites with most other organelles20. Homotypic contact sites, that are not fusion intermediates, have been described between two peroxisomes23,24,25 or two LDs26 and potentially other multicopy organelles could also form them. Homotypic interactions between ...
Reproduction is a process that involves the creation of new offsprings. Reproduction is crucial because it ensures the creation of multiple generations of species, promoting balance in ecosystems and contributing to the attainment of habitats' carrying capacity....
and the latter refers to the security provided by the human environment. As a result of synanthropic behavior, the population density, reproduction, and survival advantage of synanthropes increase. Meanwhile, the home range decreases as the animals feed on the monopolized, centralized anthropogenic ...
In evolution, viruses are an important means of horizontal gene transfer, which increases genetic diversity in a way analogous to sexual reproduction.[9] Viruses are considered by some biologists to be a life form, because they carry genetic material, reproduce, and evolve through natural selection...
Compatibility between plant parasites and their hosts is genetically determined {Citation}both interacting organisms. For example, plants may carry resistance (R) genes or deploy chemical defences. Aphid saliva contains many proteins that are secreted in

Members of the ring-forming Hsp104 family are the principal protein disaggregases in fungi (Hsp104), plants (Hsp101), and eubacteria (ClpB), but are absent in animal cells5. Hsp104 chaperones are multi-domain proteins consisting of an N domain, an M domain, and two AAA+ type nucleotide...
