Study Notes
Plant Reproduction
- Ovule: Contains the egg cell
- Anther: Produces pollen
- Stigma: Receives pollen
- Petal: Attracts pollinators with color and scent
- Ovary: Contains the ovule and develops into a fruit
- Style: Connects the stigma to the ovary
- Self-Pollination: Pollen from the same flower fertilizes the ovule
- Cross-Pollination: Pollen from a different flower fertilizes the ovule
Human Reproduction
- Zygote: Formed by the fertilization of an egg cell by a sperm cell
- Gametes: Sex cells (egg and sperm)
- Diploid: A cell with a complete set of chromosomes
- Epididymis: Stores and matures sperm cells
- Ovulation: Release of an egg cell from the ovary
- Endometrium: The inner lining of the uterus that thickens during the menstrual cycle
- Prostate gland: Produces semen, which contains sperm cells
- Fallopian tube: Carries the egg from the ovary to the uterus
- Cervix: The lower part of the uterus
- Uterus: Where a fertilized egg implants and develops
Pregnancy
- Amnion: A protective sac that surrounds the developing fetus
- Umbilical cord: Connects the fetus to the placenta
- Placenta: Provides oxygen and nutrients to the fetus
Other
- Dormant seeds: Seeds that are inactive and await favorable conditions to germinate
- Menstruation: The shedding of the uterine lining when fertilization does not occur
- Sperm: Are produced in the testis
- Fertilization: Occurs in the fallopian tube
Plant Reproduction
- Ovule: Contains the egg cell, located within the ovary of a flower.
- Zygote: Single cell formed by fertilization, contains the genetic material from both the egg and sperm cells.
- Gametes: Sex cells, which include sperm and egg cells.
- Diploid: A cell with a complete set of chromosomes, containing two copies of each chromosome.
- Anther: Reproductive structure of a flower that produces pollen.
- Stigma: Reproductive structure of a flower that receives pollen.
- Petal: The colorful part of a flower that attracts pollinators, often with fragrance.
- Ovary: Part of the flower that contains the ovules, which develop into seeds after fertilization.
- Style: The stalk that connects the stigma to the ovary, allowing pollen to travel to the ovary.
- Self-pollination: Occurs when pollen from the same flower or plant fertilizes the ovary.
- Asexual reproduction: Reproduction that involves only one parent and results in offspring that are genetically identical to the parent.
Human Reproduction
- Cervix: Lower part of the uterus, the opening to the uterus.
- Epididymis: Male reproductive organ where sperm cells are stored and mature.
- Ovulation: The release of an egg cell from the ovary, occurring roughly every month in a woman's menstrual cycle.
- Endometrium: The lining of the uterus, which thickens each menstrual cycle in preparation for pregnancy.
- Prostate gland: Gland that produces a fluid that makes up part of semen, helps nourish and protect sperm cells.
- Fallopian tube: Tube that connects the ovary to the uterus, where fertilization usually occurs.
- Amnion: A membrane that surrounds the developing fetus in the womb, filled with amniotic fluid to protect the fetus.
- Umbilical cord: Connects the developing fetus to the placenta.
- Dormant: Refers to the inactive state of seeds.
Key Facts:
- Flowers can have both male and female reproductive systems.
- Colorful flowers are often pollinated by insects.
- Pollen that is sticky and has spikes is typically pollinated by insects, not wind.
- Sexual reproduction involves the fusion of male and female gametes, producing offspring with a combination of genetic material from both parents.
- Semen contains an acidic substance to protect sperm from infection.
- Sperm cells are produced in the testes.
- Fertilization, the joining of an egg and sperm cell, takes place in the fallopian tube.
- Menstruation involves the shedding of the endometrium, which is not purely blood.
- The penis is essential for sexual intercourse and plays a role in reproduction.
- The vagina is also crucial for sexual intercourse and allows for the delivery of a baby.
