Study Notes

Plant Nutrition

  • Light is NOT an essential nutrient required for a plant to complete its life cycle.

Nitrogen Deficiency

  • The symptom of nitrogen deficiency in plants is stunted growth and yellowing of leaves.

Root Growth

  • Roots grow in a downward direction in response to gravitropism.

Hydrotropism

  • Hydrotropism is the tropism that involves the movement of a plant towards or away from water.

Auxin Function

  • The main function of auxin in plants is to promote cell elongation and cell division.

Gibberellin Effect

  • Reducing gibberellin levels in a plant can lead to stunted growth.

Cytokinin Role

  • The role of cytokinin in plants is to promote cell division and shoot growth.

Abscisic Acid Function

  • The function of abscisic acid (ABA) in plants is to regulate seed dormancy and stomatal closure.

Pruning

  • Gardeners prune to create bushier plants by stimulating the growth of new shoots.

Ethylene Effect

  • Ethylene promotes fruit ripening and senescence (aging) in plants.

Ethylene Inhibitors

  • The primary purpose of using ethylene inhibitors on fresh fruits is to prolong their shelf life.

Gibberellin Use

  • Gibberellin can be used in plant cultivation to increase seed germination and stem growth.
