Plant Nutrition & Transport IGCSE

The correct relationship between wind speed and the rate of transpiration of plants.

• as the wind speed increase, the rate of

  transpiration decrease

• as the wind speed increase, the rate of

  transpiration increase

• as the wind speed decrease the rate of

  transpiration increase

• the wind speed is not affecting the rates of

  transpiration

The correct relationship between number of stomata and the rate of transpiration of plants.

• the more number of stomata in total number of leaves, the more rate of transpiration

• the more number of stomata in total number of leaves, the less rate of transpiration

• the less number of stomata in total number of leaves, the more rate of transpiration

• there is no effect on the rate of transpiration.

Function of phloem tissues in plants.

• Transport sucrose to the fruit.

• Transport water to the leaf, which is used

  for photosynthesis.

• Transport oxygen to the leaf, which is used

  for photosynthesis.

• Transport of water to the fruit that is needed

  for development of fruit.

Organic food material that contained in phloem sap.

• Amino acid and magnesium

• amino acid and sucrose

• Sucrose and nitrate

• Sucrose and zinc

Inorganic molecules that contained in xylem sap.

• CO₂ and amino acids

• Magnesium and sucrose

• Magnesium and potassium

• CO₂ and zinc

The correct statement about translocation is ...

• Xylem vessel play important role to transpot sucrose from source to sink.

• The movement of photosynthetic products from sink to source

• Transport of sucrose only can be done in down direction of plant

• The stem tubers is a source during the spring season.

The correct relationship between humidity and the rate of transpiration of plants.

• as the humidity increase, the rate of

  transpiration decrease

• as the humidity increase, the rate of

  transpiration increase

• as the humidity decrease the rate of

  transpiration slightly decrease

• the humidity is not affecting the rates of

  transpiration
