SVEN [57.7K]
Non polar molecule move across a membrane through simple diffusion, when moving up their concentration gradient. Simple diffusion involves movement of molecules through a membrane without the help of integral membrane protein. These molecules are driven by the force of diffusion. This is different from facilitated diffusion where molecules only move with the aid of integral protein in the membrane.

<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

  2. 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 .
