S2 Spring 2021 Hort I Unit 4 Test

Vegetative growth is the growth of:

• flowers and fruits.

• fruits and roots.

• leaves, stems, and roots.

• roots, seeds, and flowers.

In which stage of growth do plants rest or grow very little?

• Dormant

• Intermediate

• Juvenile

• Reproductive

The chemical formula for photosynthesis is:

• 6CO² + 6H20 → C6H12O6 + 6O2.

• C6H12O6 + 6O2 → 6CO2 + 6H2O.

• NH4NO3 + 4H2O → 6NaCl + 4H2O.

• 4P2O5 + 6CO2 → 6H2O + 4CaCO3.

When compared to the amount of oxygen produced in the process of photosynthesis, the amount of oxygen used in plant respiration is:

• about the same.

• less.

• more.

• much more.

The main product of photosynthesis is:

• carbon dioxide.

• nitrogen.

• sugar.

• water.

The by-product of photosynthesis is:

• carbon dioxide.

• nitrogen.

• oxygen.

• water.

The plant process by which all food is manufactured is:

• absorption.

• photosynthesis.

• respiration.

• translocation.

The process of moving synthesized and absorbed food and nutrients within the plant is:

• photosynthesis.

• respiration.

• reproduction.

• translocation.

When a plant first begins growing from a seed, the stage of growth is:

• dormant.

• juvenile.

• mature.

• reproductive.

Water loss from the leaf surface through evaporation is the plant process called:

• absorption.

• photosynthesis.

• respiration.

• transpiration.
