In the vascular bundle of a dicot stemthe xylem is located on the outside and is closest to the epidermis.the phloem is composed of dead, lignified cells.phloem sieve tube cells are controlled by ‘companion’ cells.xylem cells transport water from the leaves to the roots.

Describe the difference between xylem and phloem.

Read the following statements.a)Dicot stems have conjoint, open vascular bundles with an endarch type of protoxylem.b)In dicotyledonous stems, cambium is present between phloem and xylem.c) The Pericycle is present on the inner side of the endodermis and above the phloem in the form of semi-lunar patches of collenchyma.d) In between the vascular bundles there are a few layers of radially placed parenchymatous cells̃, which constitute medullary rays.

The xylem:Group of answer choicesProtects plant organs from water lossIs composed of tracheids and/or vessel elementsIs composed of cells that are actively alive to channel sugarsIs composed of pith and cortex cells

2. All vascular plants will incorporateA) spores rather than gametes as a means of perpetuating thespecies.B) conductive tissues near the stem surface exclusively.C) conductive tissues randomly scattered through the stem.D) xylem and phloem tissue in their composition(morphology
