Needed for growth amd development. Without it, the plant cannot complete its life cycle

essential elements

Elements that can stimulate the growth of plants, but are not essentially required for growth

beneficial elements

Nutrients present in more than 1000ppm concentration

macronutrients

Required only in small ampunt of; too much wpuld cause toxicity to the plant

micronutrients

Nutrients that can betranslocated from one part to the other via tha phloem

mobile

Cannot be translocated from pne prt to the other thrpugh phloem. Transported via xylem

non-mobile

Symptoms will appear on older leaves

deficiency of mobile nutrients

Symptoms will appear on ypunger leaves

deficiency of non-mobile nutrients

Chlorosis of older leaves

nitrogen deficiency

Leaves and stem appear dark green or purple

phosphorus deficiency

Chlorosis and necrosis at later stages pf development

potassium deficiency

Chlorosis of younger leaves

sulfur deficiency

Leaf curling interveinal chlorosis

magnesium deficiency

Leaves are dry at the top

calcium deficiency

Chlorotic and necrotic spots

chloride deficiency

Nutrient mix together

nutrient binding

Is the movement of molecules and ions from one location to another

transport

Transport of solutes down a chemical gradient

passive transport

Movement of solutes against a chemical gradient; requires energy input

active transport

Movement of photosynthates throughout the plant

phloem translocation

What type of sugar is translocated via the phloem

sucrose

Any tissues/organs that has more sugar than what it needs

source

Any area that do not produce sugar

sink

Active transport of sugars into sieve tubes. Water flows into the sieve tubes and turgor pressure increases

source

Unloading of sugar, water flows out of the sieve tubes and turgor pressure decreases

sink
