Question

1.George works at a plant nursery that specializes in growing orchids. The nursery is able to provide orchids at a low cost because they clone the orchids. Which of the following describes how George clones the orchids?

		Take a sample of plant cells from the orchid to be cloned; separate the plant cells and grow them into groups of unspecialized cells called callus; use plant hormones to manipulate the callus groups into growing into new plants.
		Take orchid eggs and remove their nuclei; insert the nuclei from living cells of the orchid to be cloned into the eggs; the eggs grow and develop into new orchids.

Answer 1

Answer÷ Take a sample of plant cell from the orchid to be cloned;seperate plant cell and grow them into groups of unspecialized cell called callus; use plant hormones to manipulate the callus groups into growing into new plants.

Explanation÷ In nursery plants are mainly cheap because they are cloned by the method of tissue culture and thousands of progeny is produced from a small part of plant. Now for the purpose of tissue culture a small part of plant is taken and cell are seperated and developed into a callus ( mass of unspecialized cells) , now these callus are provided with some specific plant hormones, which helps them grow into new plants.
