Growth and Response in Plants Review

A period of decreased activity caused by structural and biochemical changes in a plant is called

• germination
• auxin
• primary root
• dormancy
• life cycle

The part of the embryo that forms the primary root of a plant is called the

• coleptile
• meristem
• radicle
• axillary bud
• epicotyl

Which region of a primary root contains cells that can develop into phloem?

• the zone of elongation
• the apical meristem
• the zone of differentiation
• the monocot shoot
• the axillary meristem

Which region of a primary root contains the apical meristem?

• zone of differentiation
• lateral bud
• zone of division
• zone of elongation
• zone of specialization

Cells begin growing and getting longer in the zone of elongation of the primary root. How does this process of elongating the cells effect the roots?

• Makes the roots wider
• Causes the roots to be pushed into the soil
• Creates new cells by mitosis
• The cells begin specializing
• Increases the height of the shoot

Examine the following diagram. What type of plant does this diagram represent?

• Long-day plant
• Short-night plant
• Short-day plant
• Day-neutral plant
• A plant that would bloom in the spring/early summer

If the main tip of the primary shoot is damaged,

• the plant can no longer grow
• root hairs develop the stem
• flowers will be unable to reproduce
• the apical meristem will repair itself
• axillary buds can still form branches or flowers

What causes the split bark seen on white birch trees?

• several layers of cork cambium
• sugar transport by phloem
• release of ethlyene
• release of abscisic acid
• invasion of bark beetles

In a typical dicot, the shoot that breaks the soil first has the shape of a(n):

• hook
• oval
• meristem
• blade
• straight line

Which kind of plant is best adapted to growing tall?

• one that undergoes primary growth only
• one that undergoes both primary growth and secondary growth
• one that has no lateral meristems
• all of the above
• none of the above
