Plants and "ism" concepts

What is another name for Gravitotropism

• Geotropism

• Magnetotropism

• Terratropism

• Geologic Sprouting

According to Gravitotropism, if a potted plant is turned sideways, which way will the stem grow?

• It will continue growing to the side

• Upwards

• Downwards

• It won't grow at all

What demonstrates positive gravitotropism?

• Plant roots growing downwards, towards Earth's center of gravity

• Plant stems growing upward, away from Earth's center of gravity

• Plant branches growing to the side, away from the trunk of the plant

• Plants that produce vegetables underground, like carrots and potatoes

A plant is touched and it moves towards the area it was touched. What is this an example of?

• Thigmotropism

• Phototropism

• Homeostasis

• Geotropism

Sunflowers start the day off by facing the east and then slowly move west. Why do they do this and what is this process called?

• They do this because the wind makes them. This is called thigmotropism

• They do this because the sun moves from the east to the west. This is called phototropism

• They do this because the sun moves from the east to the west. This is called Astrotropism

• They do this because their stem is not stable and they can't remain still

Why is it advantageous for sunflowers to move the east to the west during the day?

• They scare predators when moving

• They get more sunlight to conduct photosynthesis

• They are more stable when they move because it evenly balances weight for the plant

• Pollinators are more attracted to warm plants

What other living creatures can undergo phototropism?

• Protists

• Humans

• Viruses

• Yeast

Why do plants need water?

• They use it to make energy

• They use it to make a type of sugar

• They don't need it

• They need it to prevent them from drying out

What is hydrotropism?

• The movement of plant roots towards nutrient rich soil

• The movement of plant roots towards Earth's center of gravity

• The movement of plant roots towards water

• The movement of roots towards nitrogen

What does the root word "hydro-" mean

• Water

• Earth

• Electricity

• Magnet
