Question

The stalk-like support for a leaf is called a(n)
A) companion cell.
B) node.
C) petiole.
D) internode.
E) blade.

Accepted Answer

The petiole is a stalk-like structure that attaches a leaf to a stem. It serves as a support for the leaf and also contains vascular tissue that connects the leaf to the stem. The other options are not specific to the support of a leaf - a companion cell is a type of plant cell involved in phloem transport, a node is a point on a stem where buds and leaves attach, an internode is the section of a stem between two nodes, and a blade refers to the flattened or expanded portion of a leaf.
