Explanation:

- Tap root: Typically, these roots grow deep into the soil and are mainly for anchorage and nutrient absorption. Velamen is not found here.

- Epiphytic root: These roots belong to epiphytic plants like orchids. They have velamen, a spongy tissue that helps absorb moisture from the air.

- Fibrous root: These are thin, branching roots typically found in grasses. They do not have velamen tissue.

- Respiratory root: Also known as pneumatophores, these roots emerge from waterlogged soils for gas exchange. Velamen is not associated with them.
