The xylem in plants are responsible for (a) transport of water (b) transport of food (c) transport of amino acids (d) transport of oxygen

(a) In a plant, the xylem is responsible for transport of water.

In tall trees, water rises with the help of the transpirational pull generated by transpiration or loss of water from the stomatal pores of leaves. This is called the cohesion-tension...

Transpirational pull is responsible for the ascent of water in the xylem. This ascent of water is dependent on the following physical factors: Cohesion – Mutual attraction between water molecules Surface tension...

(c) ozone and oxygen

Transpirational pull is responsible for the ascent of water in the xylem. This ascent of water is dependent on the following physical factors: • Cohesion – Mutual attraction between water molecules •...

Essential amino acids: Amino acids which cannot be synthesized in the body but must be obtained through diet, are called essential amino acids. For example: valine, leucine. Non-essential amino acids: The...

Apply Boyle’s Law P1 V 1= P 2 V 2   200 x 10 = 1 x V 2   V2 =2000 L   No. of breaths = Total volume/ vol. consumed per breath   =2000/0.5x10 -3 L  =4x106

(d) Aspartame is metabolized by the body into two constituent amino acids and methanol. These hydrolysis products are handled by the body in the same way as aspartic acid, L-Phenylanine...

(b) An epiphyte is a plant normally grows on another plant for support. It is non parasitic, but uses the host plant for support. A plant such as tropical orchid...

(d) Biomagnification is the phenomenon of increasing concentration of compound in the tissue of organism, as the compound passes up a food chain, usually as a result of food intake....
