CHAPTER 5 RESPONSE IN PLANTS

The movement or growth of a plant in response to light

• Thigmotropism

• Geotropism

• Phototropism

• Hydrotropism

The growth response to touch

• Thigmotropism

• Phototropism

• Hydrotropism

The growth of plants response to gravity

• Thigmotropism

• Geotropism

• Phototropism

• Hydrotropism

The movement of growth in response to water or moisture.

• Thigmotropism

• Geotropism

• Phototropism

• Hydrotropism

______ is a change in a plant's direction of growth in response to the direction form which a stimulus comes.

• Growth

• Thigmotropism

• Tropism

• Gravitropism

Which type of tropism is represented in the GIF?

• Hydrotropism

• Thigmotropism

• Phototropism

• Geotropism

Which type of tropism is represented in the GIF?

• Hydrotropism

• Thigmotropism

• Phototropism

• Geotropism

What is the type of phytohormone that promotes lateral bud dormancy?

• Auxin

• Ethylene

• Cytokinin

• Abscisic acid

Which of the following is a function of cytokinin in plants

• Cytokinin help in ripening of fruits

• Cytokinin helps shoot to bend towards light

• Cytokinin promotes cell division in areas of rapid cell growth

• Cytokinin helps to absorb energy from sunlight

How does auxin make the shoots of a plant to show a positive phototropism?

• Auxin disintegrated when the plant is exposed in high intensity of light

• Auxin increases in the bright side of the stem to promote cell division

• Auxin accumulates in the shaded side of the stem to elongate the cells

• Auxin is totally destroyed in the shaded side but increases in the bright of the stem
