Difference between pollination and fertillization?
463499
pollination is the transfer of pollen from the anther to the stigma of a plant.  Fertillization is the creation by the physical union of male and female gametes, pollen and ovule in a plant

b)Unique to Angiosperms, flowering plants exhibit double fertilization whereby two sperm nuclei are deposited in the female gametophyte with each undergoing a fertilization event. The first sperm nucleus undergoes fusion with the egg cell nucleus forming the zygote while the second sperm nucleus undergoes fusion with the two polar nuclei of the central cell resulting in a triploid cell that proliferates through mitosis giving rise to the endosperm. The endosperm is often a source of nutrition for the developing embryo after fertilization and is often a starchy tissue.

Different flowers ahve diffent scent genes.In order to attract insect for entomophily(Insect assisted pollination), a flower needs specific kind of insect whose mouth parts are well suited for pollen grains to fall on stigma.

No:\nThey too distantly related.\nAlso their chromosome number and chromosome and shapes and gene layout, and individual genes are vastly different, so they cannot pair up in the fusion that is part of of the fertilisation reaction.

A flower is the reproductive structure found in flowering plants (plants of the division Magnoliophyta, also called sperms). The flower structure contains the plant's organs, and its function is to produce seeds through reproduction. For the higher plants, seeds are the next generation, and serve as the primary means by which individuals of a species are dispersed across the landscape. After fertilization, portions of the flower develop into a fruit containing the seeds.\nThe function of a flower is to mediate the union of male and female gametes. The process is termed pollination. Many flowers are dependent upon the wind to move pollen between flowers of the same species. Others rely on animals (especially insects) to accomplish this feat. The period of time during which this process can take place (the flower is fully expanded and functional) is called anthesis.

Hmm, you are in luck.  I am a biologist/chemist with a little ecology and botany knowledge and I might be able to help you out here.  But in the future, procrastination is not the answer.  Trust me, I know.\n\nAnywho, on with your project.  And, kudos to your teach.  He is getting you ready for college.  Lets see, you are wanting to germinate seeds.  It would be feasable to choose seeds with very quick germination times as probably you don't have a very long time to perform this experiment.  Some grasses will germinate in as little as 7 days.  With a little research, you can find your own seeds to use.  Next, you are going to have to decide what treatments you want to apply to each group.  And by each group, you need to have more than one "cup" of seeds, more like 4 or 5.  That is for replication.  By treatments, you could use things like adding different types of fertalizer in each group.  Use fertalizers that differ in the amount of phosphourus, nitrogen, and potassium (3 primary nutrients required by plants.)  Then, with multiple groups recieving the same kinds of fertalizer, vary the amount of sunlight (preferably artificial, like an incandesant lamp) and amount of water given.  What you will end up with is something like this:\n\nfertalizer A - 15 cups; each cup gets 1 tb of fertalizer\n      Cups 1-5 get 10mL of water and 12 hrs of "sunlight" daily\n      Cups 6-10 get 10mL of water and no "sunlight" daily\n      Cups 11-15 get no water and 12 hrs of "sunlight" daily\nRepeat this for say, 3 or 4 different types of fertalizer over a 10 to 15 day period.  Also, have 15 cups that follow the above procedure but get NO fertalizer.  After the 10 to 15 days, compare growth of the plants by measuring (probably in mm) the amount of growth produced.  \n\nBy performing a little research of your own and whatever plant seed you decide to use, you can base your hypothesis on how each fertalizer "should" affect your seeds and how much they "should" grow.\n\nFor example, lets say nitrogen is the main nutrient needed by grass.  Any of the fertalizers used that are low in nitrogen would not grow as much as the ones that get the nitrogen.  And those that do get the nitrogen, the ones that get water and sun will grow more than the others that get only sun or only water.  So, your hypothesis would be something like this:  The seeds that recieve adequate amounts of light, water, and nitrogen will have more growth after x amount of days than the other plants.  Then, you perform the experiment and see what you get.  \n\nGood luck on your experiment and if you remember, let me know what your teach thinks and what grade you get!

geographical (spatial) isolation, \nisolation of the biotope, i.e. the organisms live in the same area, but have different needs regarding the biotop, \nisolation by season or daytime, i.e. the opening of flowers is staggered depending on season or daytime, \nethological isolation, i.e. the species to be pollinated are visited by different pollinators, \nmechanical isolation, i.e. a genetically reproductive isolation within a species is diminished or prevented by differences in the flowers’ shape, \nisolation by sterility..

Contrast:\n- Asexual reproduction is done with only one individual or cell in the process (called mitosis) and usually involves splitting or grafting of the original organism.\n- Sexual reproduction occurs when one cell fertilizes another (sperm and egg are the most common terms for it) and it usually results in a more stable gene pool because more chromosome combinations are possible.\n\nCompare:\n- They both involve reproduction at the cellular level.\n- They both involve some manner of genetics (either splitting or joining)\n- They both produce offspring.

It's all about numbers.  More pollen increases the probability that a pollen grain will reach the stigma of a flower and initiate fertilization.

There is no such thing as "vitro" fertilisation, the expression is "in vitro".  The expression (latin) means literally "in glass" and so is sometimes referred to as "in petri dish" or "testtube".  The other method is "in vivo" (latin) meaning literally "in life".  This is where the the husband produces an insufficient number of sperm in any one ejaculation to guarantee impregnation, so a number of ejaculations are stored up until a sufficient sperm count is achieved and then the "whole batch" is implanted into the wife.  In "in vitro" fertilisation, the sperm and egg are introduced to each other in a petri dish and once impregnation has occurred, the fertilised egg is then implanted in the wife.

Fertilisers or fertilizers are compounds given to plants with the intention of promoting growth; they are usually applied either via the soil, for uptake by plant roots, or by foliar spraying, for uptake through leaves. Fertilisers can be organic (composed of organic matter, i.e. carbon based), or inorganic (containing simple, inorganic chemicals). They can be naturally-occurring compounds such as peat or mineral deposits, or manufactured through natural processes (such as composting) or chemical processes (such as the Haber process).\n\nFertilizers typically provide, in varying proportions, the three major plant nutrients (nitrogen, phosphorus, and potassium), the secondary plant nutrients (calcium, sulfur, magnesium), and sometimes trace elements (or micronutrients) with a role in plant nutrition: boron, manganese, iron, zinc, copper and molybdenum.

Well, nitrogen is a major ingredient in fertilizers, it is used in medicines, and it is essential for life.  \n\nBut so is carbon.  \n\nIf the question says fertilizers, I'd go with nitrogen.

Bee, fly AND moth flowers offer a nectar reward to the insect while wind pollinated flowers have very little or no nectar.  Grasses are wind pollinated and have no nectar.  Moth pollinated flowers are very long because moths have long probiscuses.  The flower has to be long so the moth gets close enough to get pollen on it's body.  Bee and fly flowers are shorter because the insect enters the flower completely to get nectar.

Seeds when sown starts multiplying the cells and they grow as plant, flowers produce pollen grains which travels through air to produce plants.
