)describe how enzymes in root cells synthesise starch.

Amylopectin is synthesized from ADP-glucose while mammals and fungi synthesize glycogen from UDP-glucose; for most cases, bacteria synthesize glycogen from ADP-glucose (analogous to starch). In addition to starch synthesis in plants, starch can be synthesized from non-food starch mediated by an enzyme cocktail.

Explanation:

there really is life in the deepest part

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.
