Which of the following can be made into crystal?

A bacterium An Amoeba A virus A sperm

Chromosomes are made up of

DNA Protein DNA and protein RNA

Which of these is not related to endoplasmic reticulum?

It behaves as a transport channel for proteins between nucleus and cytoplasm. It transports materials between various regions in the cytoplasm. It can be the site of energy generation. It can be the site for some biochemical activities of the cell.

A cell will swell up if

The concentration of water molecules in the cell is higher than the concentration of water molecules in the surrounding medium.

The concentration of water molecules in the surrounding medium is higher than water molecules concentration in the cell.

The concentration of water molecules is same in the cell and in the surrounding medium.

Concentration of water molecules does not matter.

Osmosis is a process by which molecules of a solvent tend to pass through a semipermeable membrane from a less concentrated solution into a more concentrated one. Can you pick out the option among the following which does not belong to this process?

The movement of water across a semipermeable membrane is affected by the amount of substances dissolved in it. Membranes are made of organic molecules such as proteins and lipids. Molecules soluble in organic solvents can easily pass through the membrane. Plasma membranes contain chitin sugar in plants.

You must have observed that a fruit when unripe is green but it becomes beautifully coloured when ripe. According to you what is the reason behind this colour change.

Chloroplasts change to chromosplasts Chromosplasts change to chromosomes Chloroplasts change to chromosomes Chromosplasts change to chloroplasts
