Practice quiz Seeds and plants

Vascular tissue in the plant (including xylem and phloem)

• is a series of tubes in the plant

• transports water from the roots to the leaves

• transports sugar from the leaves to the roots

• all of these are true

The stomata of a plant are found on the underside of the leaf. The function of the stomata are

• to let out carbon dioxide

• to let in carbon dioxide

• to let out glucose

• to absorb energy from the sun

Glucose is a simple sugar made during the process of

• photosynthesis

• cellular respiration

• digestion

• excretion

The source of energy to make glucose is

• ATP

• carbon dioxide

• the sun

• glucose

Seeds have stored energy in their

• leaves

• stems

• roots

• cotyledons

What molecule made by plants is broken down to provide cells with food for energy?

• carbon dioxide

• oxygen

• glucose

• water

Bromothymol blue is an indicator for carbon dioxide. What is an indicator?

• a food source

• an poisonous substance

• the energy source for photosynthesis

• a chemical that changes color in the presence of a certain substance

Bromothymol blue turns color from blue to yellow in seeds because

• seeds are producing carbon dioxide

• seeds are undergoing cellular respiration

• seeds are burning glucose to make more cells

• all of these are true

Materials necessary for photosynthesis are

• water

• carbon dioxide

• sunlight

• all of these

Seeds need which of the following to germinate?

• water, carbon dioxide, and light

• water, correct temperature, and oxygen

• correct temperature, water, and carbon dioxide

• oxygen, carbon dioxide, and correct temperature
