Open Ended

Explain the difference between a wilting vs healthy. Think in terms of vacuole and turgor pressure.

​Forces in Organisms

​Turgor Pressure

-Water within a plant cell vacuole exerts a force

-Pushes outward on its cell wall

Multiple Choice

What is turgor pressure?

• Force of chloroplast against cell wall

• Force of vacuole against the cell wall of a plant cell

• The measure of pressure per square inch

• The force of the mitochondria producing energy

Draw

Draw a plant cell with high turgor vs a plant cell with low turgor pressure

​Geotropism/Gravitropism

-A plant's growth in response to the force of gravity ​

-Roots grow down with gravity, stem grows up against gravity ​

Multiple Choice

Geotropism is a plant's response to-

• Sunlight

• Water

• Gravity

• Wind

​In order to overcome the force of gravity, seeds must use an upwards force to emerge from the soil
