Sexual And Asexual Reproduction

?
What is Sexual Reproduction and in Where does it commonly occur?
Sexual reproduction is reproduction that involves the fertilisation of egg cell by sperm cell, it requires a male and female. It occurs most commonly in vertebrates
1 of 7
What is Asexual Reproduction and Where does it commonly occur?
Asexual reproduction requires only one parent and no fertilisation is needed. It occurs most commonly in invertebrates (insects, plants, bacteria)
2 of 7
Give 4 examples of species in which Asexual Reproduction occurs
Aphids, Strawberry plants, Potatoes, Aspen trees, Spider plants, Bacteria
3 of 7
Give 2 Advantages of Sexual Reproduction
introduces variation into a population, the species can adapt to new environments, a disease is less likely to affect all the individuals in a population
4 of 7
Give 2 Advantages of Asexual Reproduction
population can increase rapidly, can exploit a suitable habitat quickly
5 of 7
Give 2 Disadvantages of Sexual Reproduction
Time and energy are needed to find a mate, Not possible for an isolated individual
6 of 7
Give 2 Disadvantages of Asexual Reproduction
does not lead to variation in a population, the species may only be suited to one habitat, disease may affect all the individuals in a population
