Pick the correct match.

cellulose: membrane or cell wall

phospholipids and protein: membrane or cell wall

gives strength to cell: membrane or cell wall

selective membrane: membrane or cell wall

The correct matches are given below:

cellulose- cell wall

phospholipids and protein- plasma membrane

gives strength to cell - cell wall

selective membrane- plasma membrane

Explanation:

The plasma membrane and the cell walls are the structures that lines the cells. The cell wall is the outer most layer present in some cells. In the plants, the cell wall is made up of cellulose. It gives strength to the and provide the turgidity.

The plasma membrane is a selectively permeable membrane made up of phospholipids. The phospholipids forms bilayer around the cell and have protein channels embedded in it. These protein channels help in transport of molecules across the membrane.

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
