<h2>
Vascular and Nonvascular Plants </h2>
Explanation:
Kingdom Plantae on the basis of vasculature is divided into two groups-vascular and non-vascular plants
.
- <u>Vascular plants </u>or tracheophytes have a proper tissue-level organization and true shoot and root structures like leaves, stem, flowers, root etc
- The tissue system or vasculature of vascular plants compromises of vascular tissues like tubular vessels – xylem and phloem
- The xylem transports nutrients to various parts of the body from the leaves.
- Phloem conducts water and other nutrients from the roots to various parts of the plant
.
- These are flowering plants that include the phanerogams – angiosperms and gymnosperms and bears flowers and fruits like the cedars, pine, clubmosses, lilies, sunflower etc.
- Dicots are with tubular vasculature.
- Non-vascular plants or bryophytes with an absence of proper tissue-level organization and true shoot or root systems
- <u>Nonvascular plants</u> are small. Their transport mechanism is poor due to lack of vascular tissues
- These plants are lack proper shoot or root system.
- It includes mosses, hornworts etc.
- Monocots are plants with scattered tube-like vessels
.
