Are vascular bundles closed in monocotyledons?

Monocotyledons:

1. Plants whose embryos contain a single embryo.
2. They have a fibrous root system.
3. Example- Grass, wheat, corn, etc.

Vascular bundles:

1. The xylem and phloem are the complex tissues that constitute the vascular bundles.
2. In dicotyledonous stems- cambium is present between xylem and phloem.
3. In monocotyledons- lack of cambium between xylem and phloem.
4. Therefore, vascular bundles are closed in monocotyledons.
