In plant stem anatomy, what is a node?
A
The vascular tissue that transports water and minerals upward (xylem)
B
The segment of stem between two nodes (internode)
C
The tip of the stem where primary growth in length occurs (shoot apical meristem)
D
The region of the stem where leaves, buds, or branches attach
Verified step by step guidance1
Understand that a plant stem is divided into different regions with specific functions and structures.
Identify that a 'node' is a specific part of the stem where important structures such as leaves, buds, or branches are attached.
Differentiate the node from other parts of the stem, such as the 'internode,' which is the segment between two nodes, and the 'shoot apical meristem,' which is the growing tip of the stem.
Recognize that vascular tissues like xylem and phloem are found within the stem but are not the definition of a node; instead, they are involved in transport within the stem.
Conclude that the node is best described as the region of the stem where leaves, buds, or branches attach, making it a critical point for plant growth and development.
