Terms | Definitions |
|---|---|
 Asexual reproduction | reproduction by a single parent which produces offspring that are genetically identical to the parent |
| Binary Fission | splitting in half of a one-celled organism. Examples: bacteria, amoeba, paramecium, and euglena |
| Budding | asexual reproduction in animals in which a new organism is produced by means of an outgrowth that breaks off from the parent's body wall. Examples: hydra, anemones, and fungi such as yeast |
| Conjugation | process in which paramecia and some prokaryotes exchange genetic material. may occur across a bridge of cytoplasm . |
| Parthenogenesis | Females of some species produce eggs that develop without being fertilized. Examples: aphids, bees, ants |
| Sexual reproduction | haploid gametes (egg and sperm formed by meiosis) from two parents unite to form diploid zygote. may increase genetic diversity. |
| Hermaphrodites | have both male and female organs |
| External Fertilization | Egg fertilized outside the female's body. Embryo develops outside the female's body. Requires water and large numbers of eggs and sperm. Decreased chance of fertilization. |
| Internal Fertilization | Egg fertilized inside the female's body. Embryo develops inside the female's body. Requires specialized organs and mating rituals Increased chance of fertilization with smaller number of gametes. |
| Oviparous | embryo develops in egg outside parent's body |
| Ovoviviparous | embryo develops in egg inside mother's body; rely on yolk |
| Viviparous | Viviparous - embryo |
| Metamorphosis | process of changes in shape and form of a larva into an adult |
| Incomplete Metamorphosis | gradual growth of an arthropod that involves change in size, but not form |
| complete Metamorphosis | egg, larva, pupa, adult |
| Scrotum | external sac which holds the testes. The scrotum helps maintain a temperature which is 1-3o C lower than body temperature. |
| Testes | produce sperm and the hormone testosterone. They are made up of seminiferous tubules (site of sperm production) |
| Epididymis | site of sperm maturation and storage; tails develop here. |
| Vas deferens | passageway for sperm from the testes to the urethra. Collects fluids from 3 different glands to produce seminal fluids (fluids + sperm = semen) |
| Seminal vesicle | produces fluid with sugar (fructose) to give sperm energy |
| Prostate gland | adds more fluid to nourish sperm |
| Bulbourethral (Cowper's )gland | secretes fluid into urethra for lubrication and acid neutralization |
| Urethra | passageway for urine and semen to exit the body; starts at the bladder and travels out through the penis |
| Penis | external organ which deposits semen into the female |
| male puberty | or Maturation. is signaled by the hormone FSH which stimulates the testes to produce testosterone. Shoulders broaden, Larynx enlarges, Pubic hair grows, Facial hair grows, Muscles develop |
| Ovaries | produce the hormones estrogen and progesterone. They also contain follicles that mature into ova (eggs). |
| Fallopian tubes | (oviducts) are the passageway from the ovary to the uterus. Fertilization usually takes place here. Cilia line the oviduct to help sweep the ovum to the uterus. |
| Uterus | (womb) muscular organ that develops a lining that will nourish a fertilize egg. This is the structure in which a fetus will develop. |
| Cervix | opening between the uterus and vagina. |
| Vagina | (birth canal) location where sperm are deposited, and passage for baby during normal birth. |
| Female Puberty | Widening of the hips,Development of breasts, Maturation of the reproductive system, Growth of pubic hair, Beginning of the menstrual cycle |
| LH | lutenizing hormone |
| FSH | follicle stimulating hormone |
