Answers
Answer:
a.Root pressure:Root pressure, in plants, force that helps to drive fluids upward into the water-conducting vessels (xylem). It is primarily generated by osmotic pressure in the cells of the roots and can be demonstrated by exudation of fluid when the stem is cut off just aboveground. b.
Anti transpirants:Antitranspirants are compounds applied to the leaves of plants to reduce transpiration. They are used from Christmas trees, on cut flowers, on newly transplanted.
c.idiogram:Idiogram is the diagrammatic representation of karyotype showing all the morphological feature of the chromosomes grouped on the basis of position of centromere and ordered in a series of decreasing size. Chromosome banding and painting technique are used to identify each chromosome.
d.active transport:Active transport is the process of moving molecules across a cellular membrane through the use of cellular energy. ...
e . crossing over:Crossing over is the swapping of genetic material that occurs in the germ line. During the formation of egg and sperm cells, also known as meiosis, paired chromosomes from each parent align so that similar DNA sequences from the paired chromosomes cross over one another.
