Reproduction Flashcards
what is sexual reproduction
the joining of a male and a female gamete
what is asexual reproduction
no fusion of gametes- only one parent needed.
what are the products of asexual reproduction in relation to their parents
identical
how can new plants be produced very quickly
by taking cuttings
4 ways of modern cloning
- plant cuttings
- embryo transplants
- tissue culture
- adult cell cloning
describe the process of adult cell cloning
nucleus is removed from egg cell. it is then fused together with an adult body cell nucleus. the fused nuclei get shocked (electrically) which causes division. the product is identical to the adult which had its cell removed, not the one which provided the egg
what is genetic engineering
genes from chromosomes of humans can be cut out using enzymes and transferred anywhere
give an example of a GM crop
one which can resist insecticides and herbicides
what are the two forms of reproduction
asexual and sexual
