Question

why dont trees shed their leaves in the summer instead of the winter to keep them cool and have them in the winterto keep the trees warm. i know its a stupid question but when ya think about it..................

Answer 1

This is only a stupid question is to people that know the answer.
After reading the answers that people give you that are sinceable you will know and then you will be smarter than the idiots that think they know it all and just belittle your question.
Notice they didnt give you an answer probably because they didnt know themselves.
I wonder what they think this question and answer site is for dont you?
Im pretty sure its not for telling people that there question is stupid.

Answer 2

Leaves serve many purposes during the summer. First, it is thier best direct sunlight to produce thier food. The direct summer sun also helps the photosynthesis process of carbon dioxide intake and oxygen output. For a tree this can only be done above a mean temperature, different for every tree, but typical a nice spring and summer temperature.

During the summer leaves provide us and thier root system shade. The leaves also provide a type of funnel system for the spring and summer rains. Water is collected and funneled towards the tree dripline so that all available resources are used to a 100%.

Answer 3

Trees don't really get hot the way we humans do. Leaves won't do anything to keep a plant warm because plants aren't warm-blooded. In the fall, the sap in leaves would freeze, and that would do a lot of damage to the trees; the sap is similar in function to our blood. Also, leaves are present in the summer to take full advantage of the longer days and use the light to produce more food, which the plant stores. Trees go dormant in the winter becuase the sap would freeze in the tissues that transport it.

Answer 4

I agree with Junior's answer. It is also a matter of hibernation. The tree sap in the tree doesn't flow as much in the winter so it doesn't have to work as hard. Since there is so much less sunlight and that is what is needed to produce food, it just kind of shuts everything off. So without the sap running thru the tree, the leaves can't live...and they fall off.

Answer 5

Leaves are for gathering sunlight for energy -- less of that in winter -- and it takes more energy to maintain the leaves through the cold season than the tree gets from having them. Thus, most trees go dormant until the energy trade-off is in their favor again. Plus, the water in leaves would freeze and kill the leaves anyway in the colder climates.

Answer 6

There is no evolutionary advantage for trees to stay cool. Trees unlike humans or other animals depend on photosynthesis (for which it needs both the leaves and the sunlight).

You may want to read about how organisms are categorized into biological groups if you really want to get to the bottom of this.

Answer 7

It's just as well they don't or else we wouldn't have much shade from the sun. Not much fun sitting under a tree in the summer that has no leaves.

Answer 8

In the summer they receive the most direct sunlight. Their leaves use this sunlight to produce food energy they need to grow and survive. Shedding their leaves in the summer would make them die.

Answer 9

I always wondered why my beech hedge keeps it leaves through the winter and now I know - it's just more sensible than the other trees!

Thanks for clearing that one up!
