| Two trees of the same species have been growing in a forest for ten years. One of the trees is located on a valley floor. The other tree is located near the top of a windswept ridge. What would you expect to be true of these trees? | |||||||||

| The formation of branches in a root allow the root to maximize surface area for the absorption of water and nutrients. How is it that new branches may begin transporting resources to the plant almost as soon as the branch is formed? | |||||||||

Ans 1) The tree on the ridge is shorter and has a thicker trunk than the tree on the valley floor.
Explain:this is so because the ridge trees face the wind which can swept the trees(given in question), there fore to avoid the fall the trees should be small and have thick trunk.
Ans 2) The new branch forms from the pericycle, which is in contact with the vascular cylinder of the root.
Explain: the root branches or the lateral roots are endogenous in origin(origin from inside). The pericycle is located in the centre near the xylene and phloem.
Cortex is located outside the pericyle.

Background: Ancient lycophytes were the dominant plants on Earth during the Carboniferous Period, which is named for the coal that formed from those ancient plants that lived 300 million years ago. As humans use fossil fuels such as coal and gas, we release carbon in the form of carbon dioxide (CO2) into the air. Because CO2 traps heat near the surface of the earth, it is known as a greenhouse gas and contributes to climate change. However, carbon is also...
