Biology 6.1.3 Flashcards
What are the Advantages of Sexual Reproduction? (3)
-Increases Genetic Variation.
-The Species can Adapt to new Environments due to Variation, giving them a Survival Advantaged.
-Disease is Less likely to Affect the Population (due to Variation).
What are the Disadvantages of Sexual Reproduction? (2)
-Takes time & Energy to find Mates.
-Difficult for Isolated Members of the Species to Reproduce.
What are the Advantages of Asexual Reproduction? (4)
-The Population can be Increased Rapidly when Conditions are Right.
-Can Exploit Suitable Environments Quickly.
-More Time & Energy-Efficient.
-Reproduction is Completed much Faster than Sexual Reproduction.
What are the Disadvantaged of Asexual Reproduction? (3)
-Limited Genetic Variation in Population- Offspring are Genetically Identical to their Parent.
-The Population is Vulnerable to Changes in Conditions, & may only be Suited for one Habitat.
-Disease is likely to Affect the whole Population, as there is no Genetic Variation.
What is Malaria Caused by?
Malaria is Caused by Parasites that are Carried by Mosquitoes.
The Malarial Parasites Reproduce ___ in the Human Host, but ___ in the Mosquito.
Asexually, Sexually.
Many Fungi Reproduce both ___ & ___. These Species of Fungi Release ___, which Develop into new Fungi.
Sexually, Asexually, Spores.
Spores that are Produced via Sexual Reproduction show ___. They are Genetically Different from each other.
Variation.
What do many Plants Produce as a result of Sexual Reproduction?
Seeds.
Some Plants are also able to Reproduce ___.
Asexually.
What are the Different ways that Plants Reproduce Asexually? (2)
-Runners.
-Bulb Division.
What are ‘Runners’?
Some Plants Produce Runners, which are Stems that Grow Horizontally away from the Parent Plant. At the end of it, new, Identical. Offspring Plants Form. Asexual Reproduction.
What is ‘Bulb Division’?
Some Plants Reproduce Asexually via Bulb Division. New Bulbs Form from the Main Bulb Underground, & then Grow into new, Identical, Offspring Plants.
