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

• more

• less

• equal

• much more

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

• absorption

• photsynthesis

• respiration

• transpiration

vegetative growth is the growth of

• flowers and fruit

• leaves and stems and roots

• fruit and roots

• flowers and shoots

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

• intermediate

• juvenille

• reproductive

• dormant

The bi product of photosynthesis is

• carbon

• oxygen

• water

• hydrogen

The chemical formula for photosynthesis is:

• 6CO² + 6H20 → C6H12O6 + 6O2.

• C6H12O6 + 6O2 → 6CO2 + 6H2O

• NH4NO3 + 4H2O → 6NaCl + 4H2O.

• 4P2O5 + 6CO2 → 6H2O + 4CaCO3

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

• absorbtion

• translocation

• phosynthesis

• respiration

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

• juvenile

• adult

• mature

• reproductive

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

• absorbtion

• traspiration

• respiration

• traslocation

The main product of photosynthesis is:

• oxygen

• nitrogen

• sugar

• water
