Unit 3 Plant Systems & Homeostasis

A change in the position of an object

• feedback

• motion

• force

The force within the cell that pushes the plasma membrane against the cell wall. Makes the plant stand tall.

• feedback pressure

• trigger pressure

• turgor pressure

? is essentially evaporation of water from plant leaves; happens most in hot weather.

• transportation

• transpiration

• sweating

The body's ability to keep the internal balance of the body stable.

• homeostasis

• feedback

• homeopathy

Transports water & minerals from the root hairs to the structures at the top of plants

• xylophone

• phloem

• xylem

Growth that happens in organisms in response to light, such as a stem bending toward a light source

• hydotropism

• geotropism

• phototropism

A change in the environment outside of the organism is an ? stimulus

• internal

• external

• feedback

? transports food & nutrients through the plant

• phloem

• xylem

• xylophone

? is a response within a system that influences the activity of that system. Positive/Negative

• homeostasis

• feedback

• tropism

The ? system is the above-ground part of a plant that includes the leaves and stems

• toot

• root

• shoot
