Biology questionpls tell anyone the three parts
Answers
Answer:
a) Osmosis
(b) Osmosis is the diffusion of water molecules across a semi-permeable membrane from a more dilute solution (with a lower solute concentration) to a less dilute solution (with a higher solute concentration).
(c) After an hour or so, the level of sugar solution in the thistle funnel will rise and the level of water in the beaker will drop slightly.
(d) For control experiment, the beaker will contain the water. At the same time, instead of the sugar solution; the thistle funnel with the cellophane paper tied on its mouth and inverted in the beaker will also contain water. (e) (1) concentrated sugar solution Cell sap (of higher concentration than that of the surrounding water) within the root hair.
(2) parchment paper cell membrane of root hair.
(3) water in the beaker water in soil.
(f) cellophane paper, egg membrane, animal bladder (any one)
(g)
(i) The roots of plants absorb water and minerals from surrounding soil due to osmosis.
(ii) Osmosis allows plants to absorb water from the soil which helps plants to keep cells alive in roots, stems and leaves.
(iii) Osmosis is also important in the opening and closing of stomata which is an important feature for the processes like transpiration and photosynthesis.
