allowing the fruit to be dispersed. The petals of the flower attract pollinators‚ due to their appearance. Flowers have evolved to attract animals to transfer pollen between individuals in dispersed populations. Stamens are the male reproductive structure‚ they produce microspores in the anthers of a flower to produce pollen grains. Pollen is able to be transferred by wind due to its waterproof coating. The carpel of an angiosperm is the female reproductive structure‚ which produces female gametophytes

Botany Essay Questions 1. Pollination is a crucial process of how plants reproduce‚ in which the male sex cell of the flower‚ pollen‚ is transferred from the stamen to the carpel‚ or more specifically‚ from the anther to the stigma. Pollen grains are completely different and unique for each flower‚ they carry the male and female genetic information and it is split exactly 50/50. The transfer is carried out by pollinators‚ which include bees‚ wasps‚ flies‚ butterflies‚ moths‚ several species

continent of Australia. Pollination is the transfer of pollen from the anther to the stigma. Asexual reproduction is another adaption when flowers can pollinate themselves o r are pollinated through the pollen of a plant their own species. Wind Pollination Wind pollination occurs when the large quantities of pollen are blown away during wind and are transported to the stigma of another flower and garminates as it travels within a tube for pollen to the ovary’s ovules. Due to the inefficiency of

carried inside a pollen‚ has to land on the stigma for successful sexual reproduction to occur. Some plants use insect for pollination. They have large and brightly coloured petal to attract insects. Sticky stigma curls down to pick up the pollen grains from the insect and nectary which secretes sweet nectar to attract insects for pollinating. For wind pollination‚ the flowers have very long anther hanging loosely out of the flower‚ large number of light‚ small‚ dry and smooth pollen grains to catch

fertilization (parthenocarpy). Flowers contain sporangia and are the site where gametophytes develop. Flowers give rise to fruit and seeds. Many flowers have evolved to be attractive to animals‚ so as to cause them to be vectors for the transfer of pollen. In addition to facilitating the reproduction of flowering plants‚ flowers have long been admired and used by humans to beautify their environment‚ and also as objects of romance‚ ritual‚ religion‚ medicine and as a source of food.

environment for reproduction. They developed flowers‚ which have distinct and pleasurable shapes‚ colors‚ smells‚ chemicals‚ and nectar to attract insects and birds‚ which help in pollination. Males developed microspores‚ which is pollen‚ and a reduced gametophytes. The pollen grain became very light weighted and easily blown about in order to increase motility. It is now possible for pollination to occur by wind‚ insects. In fact‚ many plants can even self-pollinate. The female also developed a reduced

mother cell undergoes meiosis. Each microspore develops into a pollen grain. Megasporogenesis occurs in the sporangium of the ovule of a flower. After meiosis‚ the embryo sac is produced (egg‚ nucei‚ antipodal cells‚ synergids). 3. Draw and label all parts of a complete flower. Indicate the functions of the major parts. 4. What is pollination? How does it differ from fertilization? Pollination is the transfer of pollen grains from the anther to the stigma of the plant through wind

" The flower is god’s finest workmanship in the world. It is his finest gift to mankind." Flowers hold grace‚ beauty‚ and love all inside a small‚ delicate‚ warm hearted piece of nature. Yes‚ flowers are nothing more than a foot tall‚ but the joy and happiness it brings to one‚ overpowers it by twenty. I’d rather have roses on my table than diamonds on my neck. ~Emma Goldman The flower is a pure‚ beautiful creation of nature. Everyday we are exposed to the enriched colors and charming qualities
