How do trees grow and what are they made of?

Question

I don't understand how giant, multi-ton trees just sprout out of the ground from tiny seeds. How exactly do they grow so big and where does all that matter come from??? I know it absorbs water with its roots from the ground, but that's not enough to grow a whole tree. Humans are easy to understand because we eat constantly and our body processes food so we can grow, but trees don't. Please help?????????

Answer 1

> "Humans are easy to understand because we eat constantly"

Actually, we don't, if you think about it. We only eat when it is meal-time and when we have food.

Plants, OTOH, actually *do* "eat" constantly. Whenever there is light shining on them, they are performing photosynthesis.

Photosynthesis doesn't just give the plants energy - it "fixes" CO2 from the atmosphere by combining it with water the plants take up in their roots. This CO2 is fixed into sugars; much of the sugars get used by the plant in respiration, and so *do* provide energy, but the sugars are also used in other metabolic processes.

Plants are mostly composed of cellulose (it is what their cell walls are made of) - and cellulose is a polysaccharide: it is polymerised sugars.

So plants take water up through their roots, absorb CO2 from the atmosphere, and use them to make the "building blocks" for its cellulose cell walls.

This *is* enough to grow a whole tree. Remember that trees do not grow overnight - a giant sequoia will be thousands of years old. It has grown little-by-little, absorbing CO2 and building itself up year-by-year.

Answer 2

the chemicals in the soil is also a part of a plants diet, that why you need fertile soil to make plants grow, of course there is bacteria in the soil that take "locked up" chemicals and "unlocks them"

Answer 3

the best way to grow a tree is to plant the seeds under ground and there is a special way to fertilize it. even though it may sound odd the best way to fertilize a tree is to use natural fertilization. after your next bowel movement bag you f***s and put garlic and some fish guts in it and stick is underneath the soil where the seeds are....

i have personally grown 16 plants like that up to this day

Answer 4

Trees are made of cream cheese...just like the moon
