How is the turgor pressure force exerted on the inside of a seed to split it open so it can emerge into a seedling?

• Water within the seed pushes out against the seed coat

• Gravity pushes up on the seed coat

• Gravity pulls down on the seed coat

• Water from the soil pushes in through the seed coat

What are xylem?

• series of tubes that carry water from roots to the leaves

• series of tubes that carry water from leaves to the atmosphere

• series of tubes called roots

• series of tubes call leaves

What is turgor pressure and what happens without it?

• pressure exerted by water inside the cell pushing against the cell wall

• pressure of the outside of the cell wall

• no pressure at all

• pressure exerted by gravity
