Reproduction in Animals, Plants and Humans

Hermaphroditism

• An animal with both ovaries and testes is called a hermaphrodite.
• Hermaphrodites can produce both eggs and sperm.

Mammal Reproduction

• The fertilized egg develops in the uterus of mammals.

Male Reproductive System

• The prostate gland in the male reproductive system secretes a milky fluid that is part of semen.

Cnidarian Reproduction

• Cnidarians, such as jellyfish and corals, typically develop their temporary reproductive organs during the spring or summer season.

Hermaphroditism in Animals

• The animal that does not undergo hermaphroditism is a human.

Flower Reproduction

• The style is the female reproductive organ of a flower that connects the stigma and the ovary.

Pollination

• Wind is not considered an agent of pollination.

Fruit Function

• The primary function of fruit in plants is to protect and disperse seeds.

Genetic Variation

• Sexual reproduction is likely to produce genetically varied offspring.

Onion Reproduction

• Vegetative reproduction is the primary reproductive method for an onion.

Human Reproduction

• A significant characteristic of sexual reproduction observed in humans is the formation of gametes (sperm and egg).

Asexual Reproduction

• Asexual reproduction produces offspring with no genetic variation.
• Bacteria primarily reproduce asexually.

Stolons in Plants

• Stolons are horizontal stems that grow along the surface of the soil.
• Stolons can produce new plants at their nodes.

Banana Reproduction

• A unique reproductive feature of bananas is that they reproduce asexually using rhizomes.

Frog vs. Banana Reproduction

• Frog reproduction is sexual, involving the fertilization of eggs by sperm.
• Banana plant reproduction is asexually, through rhizomes.

Fetal Development and Birth

• The survival chances for a fetus increase to about 95 percent at a gestational age of 24 weeks.
• Labor initiates the birth process.
• The process when the uterine walls shed if the egg is not fertilized is called menstruation.
• The process that occurs when an egg is fertilized is fertilization.
• Birth typically occurs 10 to 12 hours after full dilation.
• The umbilical cord is clamped and cut right after birth.
• Fertilization is the first stage in the reproduction process.
• Human pregnancy typically lasts 40 weeks.
