Chapter 36 - Transport In Vascular Plants

The water is put into circulation by supplying oxygen and with the help of propellers. More or less ventilated areas are created in which different milieu conditions are created for bacteria and microorganisms. These microorganisms feed on the organic contaminants still present in the water...Water hyacinth floats on water surface. Explain. [NCERT Exemplar] Answer: Aerenchyma present in the swollen petiole provides buoyancy to the hyacinth. Answer: The cells formed by meristematic tissue take up a specific role and lose their ability to divide. As a result, they form a permanent tissue.Water purification, process by which undesired chemical compounds, organic and inorganic materials, and biological contaminants are removed from water. Water purification provides clean drinking water and supplies treated water for domestic, industrial, medical, and pharmacological uses.This flashcard is meant to be used for studying, quizzing and learning new information. Many scouting web questions are common questions that are typically seen in the classroom, for homework or on quizzes and tests. Flashcards vary depending on the topic, questions and age group.Which tissue acts as a filter on the water absorbed by root hairs?

Tissues Class 9 Extra Questions Science Chapter 6 - Learn CBSE

The roots in the plant absorb the water and nutrients from the soil by the process of osmosis. Before the entry of the water into the vascular bundles, few nutrients and other molecules are filtered by the selective diffusion mechanism of a layer of cells called the endodermis.Question 1: How is root hair structurally adapted for absorption of water from the soil ? Answer: Transpiration pull: As the water is lost from the leaf surface by transpiration, more water molecules Answer: The sea water is saline (having more concentration of salts) and acts as hypertonic solution...The water-filtering process in mangrove roots has received considerable attention for several decades11,12,13. We also conjectured a plausible seawater filtration mechanism of halophyte roots on the basis of the revealed morphological structures of the roots and the electrokinetic...The roots are the water absorbing organs in the soil. Root hairs are more important for nutrient uptake than water because they do not contain xylem. Through an understanding of the water availability in the soil and the atmospheric demand, water can be used as a potent management...

water purification | Description, Processes, & Importance | Britannica

Water absorbed by root hairs is transferred by osmosis and diffusion through the root cortex to the stele of the root, where the xylem is located. As an observant biologist, you have undoubtedly noticed the immense physical variety of plants, even in your own back yard.The organization of tissues in the primary root is simpler than in the primary stem because no leaves are produced on the roots and, consequently, there is Since its cell walls are heavily suberized and impermeable to water its apparent function is to keep the water and nutrients (which are absorbed in...Absorption, transport and water loss (transpiration) in plants. Water is the most important component of living cells. Osmosis can be regarded as a special kind of diffusion of water molecules from a region of their high concentration to their region of low concentration through a...Which tissue acts as a filter on the water absorbed by root hairs? endodermis. Endodermal cells filter solutes from water and allow them to pass through to the vascular tissue. True or false? Root pressure can move water a long distance up the xylem because of the higher water potential of the...Water molecules, being smaller, move to limb A and The steeper the concentration gradient for a substance, the faster the rate of sucrose molecules are too large to pass through. The solution in limb A continues to diffusion for that substance. rise and vice versa for limb B. The solution level stop...
