Which material or structure is produced after a plant sperm cell fertilizes an egg cell?

Fertilized zygote or seed is produced after a plant sperm cell fertilizes an egg cell.

Explanation:

When a sperm cell of male part (stamen) combine with egg cell of female part (carpel) it produces a fertile zygote. This fertile zygote turns into a seed. When this seed is sowed in the soil under optimum environmental conditions, a baby plant emerged from the soil and turns into a mature plant.

stimulus is a change in the environment that causes an organism to react. the response is the reaction to the stimulus. some examples of stimuli for zebras are drought, to many predators, and bad feeding grounds such as dead grass or plants. zebras respond to stimuli just like all other living organisms

in a chemical reaction, the atoms and molecules produced by the reaction are called products. no new atoms are created, and no atoms are destroyed. in a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.
