Across
- 3. FERTILIZATION fertilization in which sperm cells are deposited inside the female’s body where they meet egg cells
- 4. specialized cells necessary for reproduction; in animals, male gametes are called sperm cells and female gametes are called egg cells
- 8. reproduction in which special cells,usually in plant stems and plant roots, divide repeatedly to form structures that will eventually develop into a plant identical to the parent
- 9. cells that have the potential to become many different types of cells; two types of stem cells are embryonic stem cells and adult stem cells
- 10. the new diploid(Zn) cell formed by the process of fertilization, which receives half its chromosomes from its female parent and half from its male parent
- 11. the process by which gametes arrive in the same place at the same time
- 12. plant structures called grains that carry the sperm cells in a protective case to the ovules
Down
- 1. FERTILIZATION fertilization in which a sperm cell and an egg cell unite outside the bodies of the parents
- 2. a pair of matching chromosomes
- 5. the process during which an egg cell is penetrated by a sperm cell and the haploid genetic information of both male and female gametes combines
- 6. a form of asexual reproduction in which each fragment of an organism develops into a clone of its parent
- 7. the transfer of male gametes in pollen from the male reproductive part of a plant to the female reproductive part of a plant
