Pollinationis the first required step in sexual reproduction in plants. The male portion of the plant produces the pollen – typically in the flower. A long filament, called a stamen, holds the bits of pollen at the end and one of several pollinators take the pollen grains to the ...

they can evolve along with the changing climatic conditions. humans and many multicellular organisms exhibit a sexual mode of reproduction. reproduction in plants plants reproduce by sexual and asexual means. vegetative reproduction is the main mode of plant reproduction. roots such as a corm, stem ...
The clonal plant,Caragana stenophyllaPojark, is the main shrub species in Inner Mongolia Steppe with a distribution ranging from the semi-arid zone to the intensively arid zone [18,43]. It is both economically valued as fodder, green manure, and a honey resource, and environmentally valued f...
All plants reproduce both sexually and asexually due to variation in generations. Gametophytes and sporophytes consisting of genetic elements of the plant species. Some of the complex vascular plants spend more time as sporophytes, while mosses are not the same. The noticeable part of the plant...
a. Genetic diversity occurs in sexual reproduction. b. Asexually reproducing organisms can repair their own DNA. c. Th What does the term fertilization mean in the reproduction? What part of the plant is responsible for sexual reproduction? What is asexual reproduction in prokaryotes by which ...
The cells of an animal or higher plant have two sets of chromosomes: they are diploid. When gametes (sex cells) are produced, they have onlyone set of chromosomes: they are haploid. They have undergone a process of cell division calledmeiosis. During meiosis, crossing over occurs. This make...
animals. This happens because they have pentaradial symmetry, meaning that all five sides of the echinoderms body are symmetrical. There have even been cases of entire colonies of sea stars reproducing entirely asexually. The colony of sea stars simply shed arms and reproduces copies of ...
What changes in plant reproduction have caused adaptive radiation? What prevents speciation from occurring in sympatric populations? How do flowering plants reproduce sexually? What are three mechanisms for reproductive isolation? What is the result of recombination (crossing over) during meiosis? Explain...
This grows horizontally underground, storing energy essential for the plant’s survival in harsh conditions. Rhizomes also help the plant reproduce asexually, via vegetative reproduction. Examples of rhizomes include ginger, turmeric, and bamboo. ...
