In plant growth and development, materials are moved from the source (where they enter the plant or are synthesized) to the sink (where they are utilized). Inter-organ translocation in the plant is primarily through the vascular system, the xylem and phloem. Movement in the xylem tissue is essentially a one-way acropetal (upward) movement from the […]

Partitioning of Assimilate in Plants | Crop Plants | Botany
Article shared by :
In this article we will discuss how assimilate moves in plants and how it is partitioned among different organs of the plant. Partitioning of assimilate is generally to the sinks closest to the source. For example, upper leaves export principally to the shoot apex, lower leaves to roots, and middle leaves to both. Since phloem […]
How do Plants Absorb Water ? | Plant Physiology
Article shared by : 
In this article we will discuss about how do plants absorb water from soil. Soil is the main provider of water to the roots. The soil has particles and the size of these particles increase with increase in depth. Soil is produced by weathering process of rocks, which could be chemical, physical or biological. When […]
