Q3. Which of the following is known as pond silk?
Solution
(a) The cells of are longer than their breadth. The cell wall is two layered. The inner wall is made up of cellulose and outer of pectose, when pectose comes in contact with water it gives the filament slimy or slippery. Hence, the alga is called pond silk.

Q10. In the life cycle of mosses, the gametophyte has two stages (A and B). These stages can be called
Solution
(a) The predominant stage of the life cycle of a moss is the gametophyte, which consists of two stages. The first stage is protonema stage, which develops directly from a spore. The second stage is the leafy stage which develops from the secondary protonema as a lateral bud. They consist of upright slender axe bearing spirally arranged leaves. They are attached to the soil through multicellular and branched rhizoids. This stage bears the sex organs
