Answer:
Option C, The cell membrane allows water to enter and leave the cell.
Explanation:
Options for the question are –
A. The cell membrane is an impermeable barrier that prevents water from entering the cell.
B. The cell membrane allows solutes to enter the cell, which causes the cell to shrink.
C. The cell membrane allows water to enter and leave the cell.
D. The cell membrane removes solutes from the environment.
Solution -
The cell membrane is semi permeable to water and some other substances. Whenever there is a difference in concentration or volume on the two sides of the membrane, either the solute or the solvent starts moving till equilibrium is reached. In few cases, the flow continues uninterrupted thereby increasing the cell size to its maximum extent and hence bursting it.
Hence, option C is correct
Correct answer: A) Both cell walls provide structural support but fungi is made of polysaccharides and chitin and plants are made of cellulose.
The plant cell wall is made up of cellulose. It is a complex carbohydrate that is used for the protection and provides structural support to plants. The cell wall of plants has chloroplast.
While the cell wall of fungi does not have chloroplast, they possess a rigid layer of complex polysaccharides called as chitin. It is also known to be found in the exoskeleton of insects and it is known to provide strength to the fungal cell wall.
Hence, the correct answer would be option A.
Answer:
The faster the particles are moving, the more energy they have. Why is convection more important than conduction in the troposphere? The air doesn't conduct heat well so only the first few meters of the troposphere are heated with conduction
