Asexual & sexual reproduction Flashcards
What is asexual reproduction?
A type of reproduction that requires only one parent and produces identical offspring (clones).
What are some examples of organisms that reproduce asexually?
Bacteria, fungi, hydra, strawberries, and potatoes.
What is binary fission?
A form of asexual reproduction where a single organism splits into two identical organisms (e.g., bacteria).
What is budding?
A form of asexual reproduction where a new organism grows from the body of the parent (e.g., yeast, hydra).
What are the advantages of asexual reproduction?
Fast, does not require a mate, and produces many offspring quickly.
What is a disadvantage of asexual reproduction?
No genetic variation, making species more vulnerable to disease and environmental changes.
What is sexual reproduction?
A type of reproduction that requires two parents and produces offspring with genetic variation.
What are gametes?
Sex cells (sperm and egg) that combine during fertilization.
What is fertilization?
The process where sperm and egg fuse to form a zygote.
Name two types of fertilization.
Internal fertilization (inside the body, e.g., mammals) and external fertilization (outside the body, e.g., fish).
What are the advantages of sexual reproduction?
Genetic variation, better adaptation, and reduced disease spread.
What is a disadvantage of sexual reproduction?
It takes longer and requires more energy than asexual reproduction.
How is sexual reproduction different from asexual reproduction?
Sexual reproduction needs two parents and produces genetically unique offspring, while asexual reproduction needs one parent and produces clones.
Give an example of an organism that reproduces sexually.
Humans, cats, birds, and flowering plants.
Give an example of an organism that can reproduce both sexually and asexually.
Some fungi, starfish, and certain plants like strawberries.
