QUIZ 2:ASEXUAL REPRODUCTION

Which of the following methods of asexual reproduction is usually associated with the production of spores:

multiple fission

A successful scion will produce the product of the rootstock with greater quality.

false

Animals have more mechanisms for asexual reproduction than plants.

false

Root cuttings are more commonly used than stem cuttings.

false

The stock is inserted into the scion during grafting.

false

Which of the following is not an advantage of asexual reproduction:

genetic variation of offspring

Asexual reproduction is most common in plants growing in blank climates

harsh

The technique of a growing plants in which a section of the stem is covered with soil and a partial cut is made between the parent plant and the buried part of the stem is called:

layering

The technique of asexual reproduction most commonly used in the production of fruit trees is

budding

false

Which of the following group of organisms would produce conidia:

fungi

Which of the following methods of asexual reproduction cannot occur in unicellular organism:

regeneration

The vigor of a rootstock is usually stronger than that of the root system produced by this scion.

stronger

The area or kind of community that would have the highest portion of the species reproducing by asexual means is a:

tundra

A fleshy, enlarged end of a stolon is called a:

tuber

Occasionally asexual reproduction can cause undesirable proliferation of an organism.

true

The most commonly used method of asexual reproduction used in gardening is the cutting.

true

A protozoan that divides to form two daughter cells just like itself would be undergoing:

binary fission

A bulb is a plant structure with enlarged leaf bases containing stored food surrounding a central bit of fleshy, stem tissue.

bulb

Which of the following structures contains a great deal of leaf tissue:

bulb

An adventitious bud would be formed on a:

root

An elongated, horizontal stem that grows at the surface of the ground or just below it is called a rhizome.

true

Nearly all plants can be reproduced asexually.

true

Why is grafting used in agriculture?

Plants are uniform and more vigorous, some plants may survive generations only by grafting, size of plants is controlled by grafting, Valuable fruits and flowers can be grown on strong stock

What advantages are given to animals and plants by asexual reproduction?

They can reproduce in harsh climates, they produce genetically identical offspring, they reproduce at a rapid rate
