Plant Tropisms Quiz

What is phototropism?

• Movement of a plant in response to water

• Movement of a plant in response to touch

• Movement of a plant in response to gravity

• Movement of a plant in response to light

Which part of the plant is primarily involved in positive gravitropism/geotropism?

• Leaves

• Stems

• Roots

• Flowers

What does positive turgor pressure in plant cells result in?

• Wilting of the plant

• Movement of the plant towards light

• Stiffening and standing upright of the plant

• Drooping of leaves and stems

What is the role of the vacuole in maintaining turgor pressure?

• It stores nutrients only

• It helps in cell division

• It stores water and contributes to cell pressure

• It has no role in turgor pressure

• Growth movement of plants in response to touch

• Growth movement of plants in response to water

• Growth movement of plants in response to gravity

What is thigmotropism?

• Movement of a plant in response to light

• Movement of a plant in response to touch

• Movement of a plant in response to gravity

• Movement of a plant in response to water

What is negative turgor pressure?

• The pressure that causes the plant to grow towards light

• The pressure that causes the plant to grow towards water

• The loss of pressure that results in wilting of the plant

• The pressure that causes the plant to grow away from gravity

Which tropism is involved when roots grow downwards into the soil?

• Phototropism

• Gravitropism

• Hydrotropism

• Thigmotropism

How does positive turgor pressure affect the size of the vacuole?

• It has no effect on vacuoles

• It causes vacuoles to shrink (get smaller)

• It causes vacuoles to swell (get bigger)

What is the main function of the vacuole in plant cells related to turgor pressure?

• To divide the cell into two

• To synthesize proteins

• To maintain the cell's shape and support the plant

• To transport nutrients throughout the plant
