Responses in plants that result in movement away from or toward a stimulus are called -

• tropisms

• differentiation

• adaptations

• yield

Plants have two organ systems, the _________________ system and the root system.

• vascular

• seedless

• shoot

• non-vascular

These are special structures of plants to survive drought condition except

• thick waxy layer

• extensive root system

• large bulb roots

Plant roots have extensions called root hairs. These root hairs are important in the homeostasis of the plant. Which statement best explains the importance of the root hairs to the stems and leaves of the plant?

• root hairs convert minerals into glucose for immediate use by cells

• root hairs decrease the need for osmosis and diffusion in vascular tissue

• root hairs prevent water loss in leaves through transpiration and gas exchange

• root hairs increase the surface area of the roots for nutrient and water absorption
