A single nucleotide is made up of three components: a nitrogen-containing base, a five-carbon sugar, and a phosphate group. The nitrogenous base is either a purine or a pyrimidine. The five-carbon sugar is either a ribose (in RNA) or a deoxyribose (in DNA) molecule.
Explanation:
Answer:
Carbon dioxide moves in; oxygen moves out
Explanation:
The pigment that offers the green pigmentation for green plants is known as Chlorophyll. On the surface of the leaves on green plants are microscopic openings known as Stomata in the epidermis of leaves. Stomata are generally more numerous on the underside of leaves. They provide for the exchange of gases between the outside air and the branched system of interconnecting air canals within the leaf.
On a sunny day, The concentration of carbon dioxide in the air is a regulator of stomata opening in many plants. The stomata opens (then Carbon dioxide moves in and in-turn releases oxygen after photosynthetic activities has taken place) and closes in response to the internal pressure of two sausage-shaped guard cells that surround it. The inner wall of a guard cell is thicker than the outer wall.
The main function of these Guard cells are to control excessive water loss, closing on hot, dry, or windy days and opening when conditions are more favourable for gas exchange.
