What tropism refers to the roots growing downward and the shoot growing upwards?

• Thigmotropism

• Phototropism

• Geotropism

• Hydrotropism

Which leaves represent low turgor pressure?

• A & D

• B & A

• D & A

• All except D

In a germinating seed, the downward growth of the roots and upward growth of the stem and leaves is the plant's response to-

• sunlight

• water

• osmosis

• gravity

For a plant to emerge from a seed, it must split the seed coat.  What is the force exerted by turgor pressure to split open the seed?

• Gravity pulls down on the seed, splitting the seed coat

• Water in the soil presses against the see coat splitting it

• Gravity pushes up on the seed coat splitting it

• Water absorbed by the seeed pushes out against the seed coat

How does a seed emerge from the soil as a seedling?

• The soil erodes away giving room for the seedling to emerge.

• Some animal must dig in the soil for the seedling to emerge

• The seed must exert a force against gravity and  push the shoot through the soil

• Water saturates the soil enough to push the seedling
