Aquatic plants: Fixed plants Fixed plants are held in place by their roots which grow in the water-bed. The Water Lily and Lotus are such plants. Their stems are long‚ hollow and light. These stems reach the surface of the water. The leaves and flowers‚ which grow from the top end of the stems‚ float upon the water. The leaves are broad with stomata on the top surface so that the water does not block them. Lotus The roots of lotus are planted in the soil of the pond or river bottom‚ while

Transport in Plants Matthew H. 9A 131002 Today I will be discussing our experiment and the basics of transport of minerals and water in plants. Transport in plants are called transpiration. Water evaporates from the leaves which cause a type of suction that draws water from the roots. The water travels up via the vascular bundles. This flow of water is called transpiration stream. Some pressure is created forcing some water out of the cells in into the spaces between the cells
