what is the difference between a simple and compound leaf.?

A simple leaf has an undivided blade. However, the leaf shape may be one of lobes, but the gaps between lobes do not reach to the main vein. A compound leaf has a fully subdivided blade, each leaflet of the blade separated along a main or secondary vein.\n\nI do not have permissions to give a thumbs up, but the person above me deserves one for the link.\n\nAndy

I did an experiment with this in graduate school.  When a plant has limited to no light, it invests all of its energy and growth into finding a light source.  In my experiment, the plant grew very tall and had very few leaves (since it could not go through photosynthesis anyway, why bother).  It was a very interested experiment and proved that even plant have priorities.

one of these probably has the answer\nhttp://scholar.google.com/scholar?hl=en&lr=&safe=off&q=%22secondary+compounds%22+and+%22leaf+longevity%22&btnG=Search

One of its leaves are both alike!\n\nBut I still don't understand ... why a duck?

"The raw materials of photosynthesis, water and carbon dioxide, enter the cells of the leaf, and the products of photosynthesis, sugar and oxygen, leave the leaf."\n\nAnswer:  Carbon Dioxide

both are different species belonging to same genus

the shape of animal cell can be altered while plant cell have a fixed shape. \nplant cell have cell wall but animal cell have none. \nplant cell have ssap vacoule but animal cell have none  ( if there was one it is really small).\n\nother differences if you would like to know\nthe plant cell nucleus is at one side while the animal cell nuclues is centrally located.\nthe presence of chloroplast in plant cell while animal cell have none.

Different pigments (chlorophyll a and b) absorb light in different parts of the spectrum - so this maximizes light absorption.\n\nSome pigments (carotenoids and xanthophylls) perform a protective role by absorbing excessive light. If this light was absorbed by chlorophyll, it would damage the pigment and the leaf because the plant can't keep up the dark reactions (carbon fixation) at the same rate as the light reactions.

leaf is an organ, it is part of shoot system which includes buds, stems, flowers and fruits (if the plant has any)

Why questions are often difficult to answer but you seem to have a very \nreasonable answer to explain your observation. To really confirm that the \nnongreen parts of your variegated leaves do not photosynthesize as much as the \ngreen parts, you would need to do one of the following:  \n\n1. Starch test the leaves to show that there is little or no starch in nongreen \nareas and lots of starch in green areas. This may not work on all leaves \nbecause some plants do not accumulate starch in their leaves but export \nphotosynthates as sucrose.\n\n2. Extract chlorophyll from green and nongreen areas to show the nongreen areas \nhave little or no chlorophyll while green areas have lots of chlorophyll. Just \nbecause a leaf is nongreen does not mean that there is not chlorophyll there. \nIn some nongreen leaves, other pigments such as carotenoids and anthocyanins, \nsimply mask the green chlorophyll.\n\n3. Measure photosynthesis in leaf disks cut from green and nongreen areas of \nthe leaf to show that photosynthesis occurs in green but not nongreen parts.

THERE ARE FOUR DIFFERENCES!!!!!!! NOT THREE. Some people say five\n\n1) Chloroplasts\n2) Central Vacuole and tonoplast (the membrane enclosing the vacuole)\n3) Cell Wall\n4) Plasmodesmata (channels through cells walls that connect cytoplasms of adjac3ent cells.)

basic answer.  the veins on a leaf for a monocot are parallel (like in grass)  The veins on a dicot leaf cross (such as a maple leaf)  The leaves are organs.

what is the difference between the two

None. They are two different compounds.\n\nIt looks like you want to compare a specific property of the alcohols. Please specify!

That is the concept of compound. Components of a compound lose their properties to make a compound.

fundamentally they will be the same plant but genetic they will be different they will have the same features but those features will appear in a varied state...the environment has a lot to do with how they appear

I would say it is the leaf of a plant or the plant itself.  The leaf gives off oxygen (the waste product) during photosynthesis.\n\nOr: (I grabbed this off Wikipedia)\nphotosynthesis uses water as an electron donor which is oxidized into molecular oxygen by the absorption of a photon by the photosynthetic reaction centre.
