Reproduction & Adaptations Flashcards S2
Asexual Reproduction
The process of reproduction that requires 1 parent who shares 100% of the offspring’s genetic information.
Binary Fission
A form of asexual reproduction where every organelle is copied and the organism divides in two.
Budding
A form of asexual reproduction where a new individual develops from an outgrowth of a parent splits off and lives independently.
Regeneration
Occurs when a body part has broken off and the organism grows a new one.
Fragmentation
A form of asexual reproduction where a single parent breaks into parts that regenerate into whole new individuals.
Vegetative Propagation/Plant Cuttings
The production of plants from parts of plants.
Grafting
To unite a shoot or bud from one plant, with a growing plant by insertion or placing in close contact.
Layering
The development of roots on a stem while the stem is still attached to the parent plant.
Tuber
Stems that grow underground. They develop when stem branches grow down into the ground and swell up with starch-containing cells. The buds on the tubers will grow into new plants. (Modified versions of Rhizomes)
Runner
Above the ground stems from which new plants can grow.
Sexual Reproduction
A form of reproduction where two parents are needed and produced genetically varied offspring
Mitosis
The process where animal cells divide and is an example of asexual reproduction.
Structural Adaptation
A physical feature of an organism that helps it survive to reproduce.
Behavioral Adaptation
Ways an organism acts to help them survive in their environment.
What are some advantages to asexual reproduction?
Produces more offspring, takes less time, population grows 2x faster, only 1 parent needed, requires less energy, and plants can reproduce even when conditions aren’t right for germination.
What are some examples of asexual reproduction?
Mitosis, Binary Fission, Budding, Fragmentation, Regeneration, Vegetative Propagation: Budding, Grafting, Layering, Cuttings, Runners, Tubers, Bulbs, Rhizomes, Plantlets.
What are some disadvantages to asexual reproduction?
The disadvantages of asexual reproduction are the same DNA, no genetic variation, and if the parent has a disease, it will spread to the offspring. Also, it will have a hard time adapting if there are any changes in the environment. There will be much more competition in food especially because of a lot of offspring.
What are some advantages to sexual reproduction?
Variation in offspring and the organism is more protected because of genetic variation.
What are some disadvantages to sexual reproduction?
The disadvantages of sexual reproduction are that it requires two organisms to find their mate, requires more cellular energy, and more time required for offspring development. They also don’t produce much offspring.
What are some examples of asexual reproduction?
Mitosis, Binary Fission, Budding, Regeneration, Fragmentation, Vegetative Propagation: Budding, Grafting, Layering, Cuttings, Tubers, Runners, Bulbs, Plantlets, Rhizomes
Name the two types of sexual reproduction.
Internally and Externally.
Give 3 examples of structural adaptations in animals.
Echolocation, Camouflage, Mimicry
Give me an example of structural adaptation in plants.
The way some plants have adapted to like in dry, hot deserts.
- Brightly colored flowers that attract pollinators.
Give 3 examples of behavioral adaptations in animals.
Migration, Hibernation, Hunting in Packs, Warning Calls, Mating Dances
