Current Question (ID: 12530)

Question:

Vascular bundles are surrounded by a layer of thick walled _______.

Options:

1. Bundle sheath cells
2. Cuticle
3. Casparian strip
4. Waxy cell

Solution:

Vascular bundles in plants are composed of xylem and phloem tissues and are surrounded by a layer of parenchymatous cells called the bundle sheath. Bundle sheath cells are usually thick-walled and may contain chloroplasts, which allow for photosynthesis in some plants. The bundle sheath cells act as a protective layer for the vascular tissues and help regulate the movement of substances in and out of the vascular bundles. They also provide mechanical support to the stem or leaf. The presence of bundle sheath cells is a characteristic feature of dicot and monocot plants.
