Which of the following is NOT TRUE about vegetative reproduction?

• Vegetative reproduction is a form of sexual reproduction in which offspring grow from a part of a parent plant.

• Vegetative reproduction usually involves structures such as roots, the stems, and the leaves of plants

• Many other plants can reproduce by this method, including raspberries, potatoes, and geraniums

• Plants can also reproduce asexually in a process similar to regeneration which is vegetative reproduction.

Which of the following is TRUE about the advantages and disadvantages of Asexual Reproduction?

• In asexual reproduction, it requires a mate in order to reproduce and it leads to genetic variation.

• In asexual reproduction, it does not require a mate in order to reproduce and it leads to genetic variation.

• In asexual reproduction, it does not require a mate in order to reproduce and it enables organisms to reproduce rapidly.

• None of these.
