Question

With neat labelled diagram describe pathways for water uptake by root.

Answer 1

Water movement over the root occurs in two ways: apoplast and symplast.

1. When some water flows across the root through the cell wall and the intercellular spaces of cortrical cells, this is referred to as the apoplast pathway. This pathway extends all the way to the endodermis.
2. The symplast pathway refers to the passage of water from one live cell to another via plasmodesmata. It is also known as the transmembrane route.
