Answer» 1. Ans.Nephrons are the filtration units of kidney. Each kidney has a large no. of nephrons. The process starts with filteration of urine. 2. Ans.Plants get rid of:1. of water by transpiration.2. waste products may be stored in vacuoles or may be stored in leaves which fall off.3. resine and gums are stored in xylem.4. some waste substance may be excreted in the soil.5. as by products move out of the plants by diffusion through stomata. Ans 3. The amount of urine produced depends on the amount of excess water and dissolved wastes present in the body.
