1. In humans and other complex organisms, why does mitosis occur? why does meiosis occur?

2. List and describe the sexual reproductive organs of an angiosperm. Be sure you can recognize the male reproductive parts and the female reproductive parts.

3. Show how the following words are related by using then in a sentence: zygote, fertilization, gamete, sperm, egg, meiosis, mitosis.

4. what is the difference between heterozygous and homozygous? give examples.

1. Mitosis occurs so somatic cells can divide. Meisos is for gametic cell division (sperm and egg only...unless you are talking about angiosperm (aka flowering plants) which could be pollen and egg).

too lazy to do the others
