Tropisms Pretest

Plants reacting to gravity is called:

• Phototropism

• Geotropism/Gravitropism

• Germination

• Thigmotropism

A seed first starting to sprout by its root digging into the soil is:

• Phototropism

• Gravitropism/Geotropism

In order for a seed to germinate, it needs water and ???

• Soil

• Turgor pressure

• Energy/heat

• Gravity

• Sunlight

When plants grow in towards the light, this is called:

• Phototropism
