[Answer] Water will move from the _____ to the _____ by _____.

Answer: Hypotonic
Water will move from the _____ to the _____ by _____.
Transpiration is the process of water movement through a plant and its evaporation from aerial parts such as leaves stems and flowers. Water is necessary for plants but only a small amount of water taken up by the roots is used for growth and metabolism. The remaining 97–99.5% is lost by transpiration and guttation. Leaf surfaces are dotted with pores called stomata (singular “stoma”) and in most pl…
Transpiration is the process of water movement through a plant and its evaporation from aerial parts such as leaves stems and flowers. Water is necessary for plants but only a small amount of water taken up by the roots is used for growth and metabolism. The remaining 97–99.5% is lost by transpiration and guttation. Leaf surfaces are dotted with pores called stomata (singular “stoma”) and in most plants they are more numerous on the undersides of the foliage. The stomata are bordered by guard cells and their stomatal accessory cells (together known as stomatal complex) that open and close the pore. Transpiration occurs through the stomatal apertures and can be thought of as a necessary “cost” associated with the opening of the stomata to allow the diffusion of carbon dioxide gas from the air for photosynthesis. Transpiration also cools plants changes osmotic pressure of cells and enables mass flow of mineral nutrients and water from roots to shoots. Two major factors influence the rate of water flow from the soil to the roots: the hydraulic conductivity of the soil and the magnitude of the pressure gradient through the soil. Both of these factors influence the rate of bulk flow of water moving from the roots to the stomatal pores in the leaves via the xylem. Mass flow of liquid water from the roots to the leaves is driven in part by capillary action but primarily driven by water potential differences. If the water potential in the ambient air is lower than the water potential in the leaf airspace of the stomatal pore water vapor will travel down the gradient and move from the leaf airspace to the atmosphere. This movement lowers the water potential in the leaf airspace and causes evaporation of liquid water from the mesophyll cell walls. This evaporation increases the tension on the water menisci in the cell walls and decrease their radius and thus the tension that is exerted on the water in the cells. Because of the cohesive properties of water the tension travels through the leaf cells to the leaf and stem xylem where a momentary negative press… Read more on Wikipedia
Plants regulate the rate of transpiration by controlling the size of the stomatal apertures. The rate of transpiration is also influenced by the evaporative demand of the atmosphere surrounding the leaf such as boundary layer conductance humidity temperature wind and incident sunlight. Along with above ground factors soil temperature and moisture can influence stomatal opening and thus transpi…
Plants regulate the rate of transpiration by controlling the size of the stomatal apertures. The rate of transpiration is also influenced by the evaporative demand of the atmosphere surrounding the leaf such as boundary layer conductance humidity temperature wind and incident sunlight. Along with above ground factors soil temperature and moisture can influence stomatal opening and thus transpiration rate. The amount of water lost by a plant also depends on its size and the amount of water absorbed at the roots. Transpiration accounts for most of the water loss by a plant by the leaves and young stems. Transpiration serves to evaporatively cool plants as the evaporating water carries away heat energy due to its large latent heat of vaporization of 2260 kJ per litre. • The effect of temperature on the transpiration rate of plants. • The effect of wind velocity on the transpiration rate of plants. • The effect of humidity on the transpiration rate of plants. During a growing season a leaf will transpire many times more water than its own weight. An acre of corn gives of…
