Horticulture I Plant Growth and Development

The main product of photosynthesis is:

• carbon dioxide

• nitrogen

• sugar

• water

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

• about the same

• less

• more

• much more

The plant process by which all food is manufactures is:

• absorption

• photosynthesis

• respiration

• translocation

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

• photosynthesis

• respiration

• reproduction

• translocation

Water loss from the leaf structure through evaporatoin is the plant process called:

• absorption

• photosynthesis

• respiration

• transpiration

Plant roots take water from the soil trough the process of:

• absorption

• photosynthesis

• reproduction

• respiration

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.

The by-product of photosynthesis is:

• carbon-dioxiide

• nitrogen

• oxygen

• water

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

• dormant

• juvenile

• mature

• reproductive
