Reproduction and Life Cycles in Organisms Quiz

Pollination is a process in sexual reproduction involving the transfer of pollen, not a method of asexual reproduction.

Fertilization usually occurs in the fallopian tube in humans, where the sperm meets the egg.

The process of a sperm cell fusing with an egg cell is called fertilization.

The placenta facilitates the exchange of nutrients and waste between the mother and fetus during pregnancy.

In plants, the process by which a seed is produced involves fertilization.

Vegetative propagation is a type of asexual reproduction in plants where new individuals grow from existing vegetative structures.

Parthenogenesis is a form of asexual reproduction producing genetically identical offspring without fertilization.

Sexual reproduction leads to genetic variation in offspring, a key characteristic distinguishing it from asexual reproduction.

Gametes play a crucial role in sexual reproduction by transmitting genetic information from parent to offspring.

The umbilical cord connects the developing fetus to the placenta, ensuring the exchange of essential substances.

External fertilization typically requires water for the union of sperm and egg outside the organism's body.

The pistil is the female reproductive organ in flowers, containing the stigma, style, and ovary.

Dioecious plants have distinct male and female individuals, each producing either male or female reproductive structures.

Testosterone is the hormone responsible for the development of secondary sexual characteristics in males.

Frog metamorphosis is an example of indirect development, where organisms undergo distinct larval stages before reaching maturity.

Viviparity is a reproductive strategy where the parent provides nutrients and protection to the developing offspring.

Double fertilization in angiosperms results in the formation of a triploid endosperm, providing nourishment to the developing embryo.

Vegetative propagation in plants enables reproduction without the formation of seeds.

Viviparous animals give birth to live young, as opposed to laying eggs outside the body.
