What does angiosperm mean? What structures of the flower are female? What structures of the flower are male? What is the function of the petals of the flower? The process of Answer occurs in the flower anther to create haploid Answer followed by mitosis to create Answer. The process of Answer occurs in the flower ovary to create the haploid Answer followed by mitosis to create the Answer and the n + n Answer. State one difference between monocots and eudicots. Explain how angiosperms undergo a double fertilization. What part of the flower develops into a fruit? How is a simple fruit different from a complex fruit? Give an example of a fleshy fruit: Answer Give an example of a dry fruit:Explanation / Answer
7.Ans- flowering plant also called as angiosperm plant(angiospermae) large group of plant on earth, angiosperm plant produce seed which enclosed in a carpel, and have flowers, and it’s most (diverse) group of the land plant for example-herbaceous plant, grasses, shrubs, most trees.
8.Ans- structure of female flower- consist of ovary(contain 1 or 2 ovules), style, stigma. Ovary is base of flower, tubular structure emerge from the ovary is called style and upper part of style is stigma which receptive to the pollen grain.
9.Ans-structure of male flower-consist of stamen, or anthers, stalk, the stamen are reproductive part of male flower, and it made of paired of anthers filament(sac contain pollen grain), which are produce pollen grain, and this pollen received by female stigma for fertilization
10.Ans- petals of the flower are called modified leaves which surrounded by the reproductive part of the flowers. Petals are often bright coloured or may unusually or different shape to attract the pollinators toward flowers for fertilization(pollination). And all the petals of flowers are non as corolla which main role attract pollinators.
11.Ans- process of flower anther create haploid, in angiosperm microspore developed in microsporangium and form mature male gametophyte, which fertilize female gametophytes.
First mature anther 2n cell undergo mitosis and produce two haploid generative or vegetative cell, and generative cell fused with polar nuclei of female. Vegetative cell make tube so male nuclei reach to female polar nuclei .
12.Ans- process of flower ovary created haploid egg, in angiosperm haploid megaspore produce in megasporangium, it also called embryo sac. female gametophyte developed through 3 round of mitotic-division. 2 synergid cell, guid the pollen tube, 3 antipodal cells, and large central cell which contain two polar nuclei.
13.Ans- seed structure is the main difference between the monocots & eudicots, when a seed germinates, in monocot- form one seeding leaf menas one cotyledon only, but in eudiocots have two seed leaf means two cotyledon.
14.Ans- double fertilization is unique for the flowering plants, in the flowering plant, one male sperm nucleus fused with egg cell(synergid) to produce zygote(2n) and other sperm nucleus fused with central two polar nuclei, give rise to form endosperm (polyploid) typically called triploid 3n cells
15.Ans- ovary, is a part of the flower which developed into fruits. reproductive structure of female developed into fruit. Fruit tissue cells are surrounded the seed, which drive from ovary. And ovule form seeds.
16.Ans- difference between simple or complex fruit, simple fruit-fruit which develop from the single ovary in the single flower. Or it may fleshy or may dry. 3 type of fleshy simple fruit- berry 2.pome 3.drupe. complex fruit – developed from more than one ovary in single flower, for example-raspberry a aggregate frui, pineapple (multiple fruit),tomato(compound ovary)
17.Ans- apple, avocados, pears, watermelon,
18.Ans- mango’s, raisins,apricots,pawpaw,
