What will you learn in CBSE Class 11 Biology Chapter 11?

In this particular chapter the students will get to know about the important transport processes which the plants go through. While exploring the mechanism basic the students will get a lot of information about the structure of the cell along with the anatomy of the plant body through various kinds of in-depth explanation and illustrations.

The solutions which the experts have shaped for the students have been placed in a way which will be easier for them to understand. All the concepts in connection with the topics such as Means of Transport, Plant-Water Relations, Long Distance Transport of Water, Transpiration Uptake and Transport of Mineral Nutrients and Phloem Transport Flow from Source to Sink have been given equal importance.

The explanations will clear all the confusions of the students in an effective way. The topics which have dealt here are Diffusion Facilitated Diffusion, Active Transport Comparison of Different Transport Processes, Water Potential Osmosis, Plasmolysis, Imbibition, How do Plants Absorb Water? Water Movement up a Plant Transpiration and Photosynthesis – a Compromise, Uptake of Minerals, Translocation of Mineral ions and the Pressure Flow or Mass Flow Hypothesis.

Important Notes On Transport In Plants

  • Osmotic Pressure-External pressure applied to prevent the diffusion of water. It depends upon solute concentration. Numerically, osmotic pressure is equal to osmotic potential osmotic pressure has positive (+) sign. Osmotic potential has negative (-) sign.
  • Turgor Pressure-Due to osmotic entry of water, the protoplasm of a plant cell presses the cell wall towards the outside with a force, it is called Turgor Pressure.
  • Diffusion Pressure-The pressure exerted by the tendency of the particles to diffuse from the area of higher concentration to lower concentration. It is directly proportional to the concentration of particles of diffusing substance.

OSMOSIS

Osmosis is movement of solvent or water molecules from the region of their higher diffusion pressure or free energy to the region of their lower diffusion pressure of free energy across a semipermeable membrane. Water molecules move from higher water potential to lower water potential until equilibrium is reached.

  • Hypotonic solution: The external solution which is more dilute than the cytoplasm.
  • Hypertonic solution: The external solution, which is more concentrated than the cytoplasm.
  • Isotonic solution: When the external solution balances the osmotic pressure of the cytoplasm.

Important Terms Related To Chapter 11

  • Plasmolysis: Process of shrinkage of protoplast in a cell due to exosmosis in hypertonic solution. If a plasmolysed cell is placed in water or a hypotonic solution it becomes turgid.
  • Casparian strip: It is the tangential as well as radial walls of endodermal cells having the deposition of water impermeable suberin.
  • Transport of water in plants: Water is absorbed by root hairs by diffusion. Then water moves upto xylem by two pathways apoplast and symplast pathway.

Apoplast Pathway-Movement occurs through the intercellular spaces or walls of the cell, without entering the cytoplasm. This movement is fast. In roots, movement of water occurs via apoplast except at the carparian strip, most of water enters through apoplast.

Symplast Pathway

Water enters the cell through cell membrane and travels intercellularly through plasmodesmata. This movement is slow. At casparian strip region water moves through symplast.

Imbibition: Imbibition is the phenomenon of absorption of water by the solid particles of an adsorbent causing it to enormously increase in volume without forming a solution.
