  1. Translocation


Movement of organic compounds from sources to sinks through the phloem.

2
New cards
  1. Source

A place where organic compounds are produced, such as photosynthetic leaves.

3
New cards
  1. Sink

A place where organic compounds are used or stored, such as roots, fruits and seeds.

4
New cards
  1. Phloem transport

Transports manufactured food and nutrients to growing and storage parts of the plant.

5
New cards
  1. Direction of translocation

Food can move upwards and downwards through the plant.

6
New cards
  1. Main sugar transported in phloem

Sucrose, because it is soluble and metabolically inert.

7
New cards
  1. Plant sap

The nutrient-rich, viscous fluid transported through the phloem.

8
New cards
  1. Difference between transportation and translocation

Transportation moves water and minerals through xylem; translocation moves organic food through phloem.
