ISC Board Important Questions Biology [Set-1] Q1. a) (i). Absorption spectrum and Action spectrum Answer: A curve obtained by plotting the amount of absorption of different wavelengths of light by a particular pigment is called absorption spectrum of that pigment. An action spectrum is a curve showing the effectiveness of different wavelengths of light in stimulating the process being investigated. (ii). Heart Wood and Sap Wood Answer: In most trees the outer light colored region of the wood

PLANT CELL Introduction Plant cell is the basic unit of structure and function in nearly all plants. The range of specialization and the character of association of plant cells are very wide. In the simplest plant forms a single cell constitutes a whole organism and carries out all the life functions. In just slightly more complex forms‚ cells are associated structurally‚ but each cell appears to carry out the fundamental life functions‚ although certain ones may be specialized

their fibers‚ which are traditionally used to make paper‚ cloth‚ or rope. The fibers may be chemically modified‚ like in viscose or cellophane. Botanically‚ the fibers harvested from many of these plants are bast fibers; the fibers come from the phloem tissue of the plant. The other fiber crop fibers are seed padding‚ leaf fiber‚ or other

During the process of scrutinizing a banana‚ involuntary recurrent memories and repressed thoughts and emotions were consciously recalled. Banana is an ordinary nutritional intake that if one devotes time to observe and analyze‚ he or she might discover that not only does it associate with monkeys‚ but also within his or her inner values. With that being said‚ my observations of the banana directed my consciousness towards the sensation‚ perception‚ and thoughts of my inner process. What’s memorable

in the margins of leaves. There are three levels of transport in plants: uptake and release of water and solutes by individual cells‚ short distance cell to cell transport at tissue and organ levels‚ and long distance transport of sap by xylem and phloem at the whole plant level. The transport of water is controlled by water potential. Water will always move from an area of high water potential to an area with low water potential. This water potential is affected by pressure‚ gravity‚ and solute concentration

Water lab Research Question: How many drops of water can fit on a coin? (Water properties involved are cohesion and surface tension. Cohesion plays a consequential role in the transport of water within plants specifically within the phloem. Surface tension also dictates an important role within the transpirational pull of the xylem.) Variables: Variables | Type of Variable | How it was manipulated | Independent | Water drops‚ different types of water | Determining how many drops of the
