All living things need energy; it is a requirement for life. in a typical cell, atp, the high energy molecule, is produced in the in the presence of a sugar (glucose) and a) nucleus; oxygen b) er; carbon dioxide. c) mitochondria; oxygen. d) vacuole; water vapor.

The answer is C) mitochondria; oxygen

Adenosine triphosphate (ATP) is the main molecule for storing and transferring energy in cells. It is also called the energy currency of the cell.  ATP molecule composed of three phosphate groups. These phosphate groups are linked to one another by two high-energy phosphoanhydride bonds. ATP is produced in the mitochondria of all the living cell in the process of cellular respiration. During cellular sugar is oxidized in presence of oxygen to produce ATP.  

both male and female gametes are produced by meiosis of the germ cells. therefore, both male and female gametes are haploid. one male and one female gamete unite during the fertilization to form the diploid zygote. in seed bearing plants, pollen grain is the male gametophyte, which produces sperm cells.
