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.
. Igneous rock is formed through the cooling and solidification of magma<span> or </span>lava<span>. The magma can be derived from </span>partial melts<span> of existing rocks in either a </span>planet<span>'s </span>mantle<span> or </span>crust<span>. Typically, the melting is caused by one or more of three processes: an increase in </span>temperature<span>, a decrease in </span>pressure<span>, or a change in composition. In this case, the "rock" is ice. The hot water has cooled through a change of temperature to create a solid structure (ice).</span>
