plants in trees have many more mitchondria than plants on ground?

In an eukaroyotic plant cell the mitochondria is contained in the nucleus. The mitochondria are the "power plants" of the cell. There are three main classes of plant cells: Epidermis, Vascular tissue, and Ground tissue. The second type transports materials through the plant. Since the plant is larger, being a tree, perhaps the longer distance means the cells need more mitochondria to travel that longer distance. In a bush this would not be neccessary. The third type peforms photosynthesis and does starch storage and stuctural support. These types are further broken down into Parenchyma, Collenchyma, and Sclerenchyma. Since it is a larger plant and more starch needs to be stored, perhaps this explains it. More powerhouses would seems to me to be a benefit in greater starch storage for a larger plant. I did not know there could be more mitochondria in one plant cell than in another. Your statement was the first I'd heard of it.

it becomes a, 'more often than not plant holder'.

Because the tree is not a plum tree

No. In fact not every one of them. The cells which make up the roots of the plants do not because they are not designed for the process of photosynthesis.

I think this is what you're after.\n\nIt is an accident of astronomy that our earth has a tilt of 21.3 degrees.  (That's the current tilt ... it ranges between 21 and 25 degrees every 41,000 years.)  \n\nAs a result, trees far away from the equator see a variable amount of sunlight over the course of one journey around the sun (one year).  Trees (such as palm trees) near the equator (specifically between the tropics) do not see much variability in the sunlight, so the following does apply to them.  \n\nWhen tilted towards the sun, the days are longer, and the sun higher in the sky, and the tree wants as much area dedicated to photosynthesis as possible.  So leaves are good.  \n\nBut when tilted away from the sun, the days are shorter, the sun not as high up, and photosynthesis is more difficult.  The leaves are a premium ... they're consuming more food than they are producing with photosynthesis.  Plus, with temperatures dropping, water in the leaves is in danger of freezing, which burdens the branches with so much extra weight that they can break.  So it is better to shed those leaves for that part of the journey around the sun.  (This is less of a problem with trees, like pine trees, that have needles instead of leaves.)\n\nIs that what your after?  (Great question!)

Bamboo roots spread out far from the plant near the top of the soil, and shoots from the roots become trees. Bamboo grows tall very fast and spreads aggressively. Of course, bamboo is hollow.

Excellent question.  \n\nThis is due to a process called osmosis.  Osmosis is the net movement of water molecules in and out of a partially permeable membrane (a kind of barrier that only allows certain molecules to pass through), from a region of their higher concentration to a region of their lower concentration.\n\nIts pretty self-explanatory here.  Since the concentration of water is higher inside than outside of the plant, water moves out of the plant, resulting in the plant dehydrating and dying.

Check these factors out\n\n1.  The amount of pollutants in the air are lower at night\n2.  The amount of oxygen released by plants is maximum at night and C02 levels are least reduced.\n3.  Humidity levels are generally high at night\n4. Charged particles are less at night, because there is no more "ionizing" sunlight (smell is an electrochemical process\n\nI could think of other reasons, but I'm out of ideas.

Taking a guess here but I  would think in a way.. some plants have growth underground like carrots, potatoes, onions, etc. The underground roots stay underground lol, they absorb fluids, aka water and grow from underneath then the stems are actually what blossoms out of the dirt. It is the result of the outgrowth the root has made. I have no idea what I'm saying here :P

I'm not sure if I understand the part about "tree is bad because goats scared of cars," maybe its lost in translation.  \n\nDon't worry about roots unless you have terra cotta sewer pipe.  If you have PVC (plastic) sewer pipe, the tree won't invade it because they are sealed.\n\nIf you don't know, just find the clean out and dig down to the pipe in your yard.  Really, though if your plumbing isn't clogged, you don't have a root problem.

Plants have small openings on the underside of their leaves called stomata. The roots pull in water and it travels up and out the stomata. The lower humidity outside the plant pulls the water out.

plants that r fixed to soil. eg- trees

Because the roots are on the dirt which means in the bottom side...if you grew trees upsidedown you would be planting what actually grows and it wouldnt have enough oxygen...

They have more chloroplasts, which are plastids, in them.

I will guess that you intended to smother the plant (prevent it from breathing) by covering the undersides of the leaves.  While it is true in many plants that there are more stomata (breathing holes) on the undersides of leaves, there are also stomata on the tops of leaves.  Perhaps there are enough stomata on the top of the leaf to allow the plant to continue to live...or to last longer (and slowly die) compared with what you expected.

The plants have to attempt to get more sunlight in the limited shade. Thus, they expand their surface area to catch more sunlight to get as much sunlight as another plant that is directly in the sunshine.

peanuts grow underground and cashews grow in pods on trees
