Answer:

C. Vitamins

Explanation:

The factor Vitamin is being tested in this experiment. For an experiment to occur, it is necessary that we plan an experimental group as well as a placebo group (control group). In this experiment, all other factors have the same experimental group as well as the same placebo group except for the factor vitamin. The factor 'vitamin' has a experimental group in which the particular vitamin is given to the  object of test and a placebo group in which the vitamin is not given to the object of test. Hence, vitamin is the variable that is being tested in this experiment.

Plant embryos __________. a. rely on protection and resources supplied from the maternal plant. b. result from fertilization ext
Roman55 [17]

Answer:

A) rely on protection and resources supplied from the maternal plant.

Explanation:

The embryo is a structure formed after the fusion of the male gamete and female gamete. A diploid zygote is formed after cellular division forms the embryo in the female gametophyte and therefore is considered the diploid tissue.

The embryo requires the nutrients for growth and absorb them from the surrounding female gametophyte structure like endosperm in the angiosperm. The embryos grow and form the sporophytic structure.

Thus, Option-A is correct.
