Answer:
Zygote, the nucleus of male and female gametes join, mitosis
Explanation:
The human belongs to the animal kingdom which begins their life when the male and female gametes fuse through a process called Fertilization.
The process of fertilization involves the fusion of the nucleus or the genetic material of the male and female gametes. The process forms a diploid cellular structure called the zygote. After the formation of the zygote, the first cell division or mitosis produces the embryo which develops into an organism.
Answer: Both.
Explanation: Plants produce both asexually and sexually. If they produce asexually, they will use mitosis to produce offsprings. Roots can rise up to new plants or they can propagate by budding or cutting. Like a plant's root can be attached to another plant; that energy from the plant that is attached will get it. If a plant produces sexually, it will grow seeds, and those seeds will turn into a fruit.
