Plant Nutrition

These flashcards cover key vocabulary and concepts related to plant nutrition as outlined in the lecture notes.

Cellular respiration

The process by which plants convert sugars into energy within their tissues.

Photosynthesis

The process by which plants use sunlight to convert carbon dioxide and water into sugars and oxygen.

Apoplast

The compartment within plant systems that includes everything external to the plasma membrane, including cell walls.

Symplast

The compartment within plant systems that consists of the cytosol and interconnected cytoplasmic channels.

Root pressure

The pressure developed in the roots that forces sap upwards through the plant.

Cohesion-tension mechanism

The process through which water is pulled up through the plant due to cohesion among water molecules and tension generated by transpiration.

Phloem sap transport

Mechanism by which nutrients and sugars move from source to sink within the plant via positive pressure.

Hydraulic pressure

The pressure in plant tissues caused by water uptake, crucial for maintaining cell turgor.

Nutrient acquisition

The process by which plants obtain essential nutrients from their environment, particularly soil.

Mycorrhizae

Symbiotic associations between fungi and plant roots that enhance nutrient uptake.

Nitrogen fixation

The process by which specific bacteria convert atmospheric nitrogen (N2) into ammonia or nitrates that plants can use.

Nutrient deficiency

A condition that arises when a plant lacks essential nutrients, affecting its growth and development.
