No.06 Determining water potential of potato tuber cells: the weighing method If a plant cell is in equilibrium with an external solution of such a concentration that there is not net loss or gain of water‚ the water potential of the external solution will be equal to the water potential of the cell. Use of this fact can be made in estimating the water potential of a plant tissue. Samples of tissue are immersed in a range of external solutions of different strengths. The solution that induces

Potato is vegetative propagated‚ meaning that a new plant can be grown from a potato or piece of potato‚ called a “seed”. The new plant can produce 5 through 20 new tubers‚ which will be genetic clones of the mother seed plant. Potato plants also produce flowers and berries that contain 100-400 botanical seeds. Potatoes can have white‚ yellow‚ pink‚ red‚ purple‚ and even blue flesh color. Yellow is primarily due to

states that “the passive diffusion of water molecules across a selectively permeable membrane down a concentration gradient” (Taylor and Bruenn‚ 2009)‚ moving water from a high to a low concentration‚ so in this case water would move from the potato tuber to the sucrose solution reducing the weight of potatoes.

esculenta). Cassava tubers were gathered‚ ground and squeezed to extract starch. Cassava (Manihot esculenta)‚ also called manioc‚ tapioca or yuca‚ is one of the most important food crops in the humid tropics‚ being particularly suited to conditions of low nutrient availability and able to survive drought (Burrell‚ 2003). The plant grows to a height of 1 to 3 m and several roots may be found on each plant. Although cassava leaves are sometimes consumed‚ the major harvested organ is the tuber‚ which is actually

Hydrilla: An Invasive Species Hydrilla verticillata‚ otherwise known as Hydrilla is an aggressive water weed and is said to be one of the world’s worst invasive aquatic plants. Hydrilla in temperate places around the globe and somehow made its way to the United States. Hydrilla has a special advantage; it grows under lower light conditions than nearly any other species‚ it only needs about 1% of sunlight. This advantage allows hydrilla to grow underneath other plants and survive greater depths;
