Lack of oxygen can be dangerous for a plant. Why is this?

• Oxygen is needed for photosynthesis

• Oxygen is needed for cellular respiration

• Oxygen needs to flow into the stomata

• Plants need oxygen to breathe

Match the plant organ to the function

• Production of seeds for reproduction

• Fruit

• Absorb water and nutrients from the soil

• Root

• Dispersal and protection of seeds

• Flower

• Support the rest of the plant; transport

• Leaf

• Main site of photosynthesis

• Stem

Match the leaf part to the function.

• Main site of photosynthesis

• Bundle sheath cells

• Hydrophobic layer to conserve water

• Cuticle

• Control the stomata for gas exchange

• Mesophyll cells

• Protects the xylem/phloem

• Epidermal cells

• Secrete cuticle; protection

• Guard cells

Match the plant tissue to the function

• Transports water + minerals up the plant

• Vascular bundle

• Contains xylem + Phloem

• Phloem

• Protects growing root

• Root cap

• Region of active growth in the root

• Xylem

• Transports sugar up and down the plant

• Apical meristem

As water travels from the roots to the leaf, what is the order of physical processes that help it move?

• Transpiration Pressure

• Root pressure

• Cohesion / Adhesion

True or False: All underground parts of a plant belong to the root system

• True

• False

True or False: Roots can be classified into taproot and fibrous root systems

• True

• False
