11/30/12 IB Biology 2‚ Period 1 Transpiration Lab Background Information- Transpiration is the loss of water from a plant. Plants transpire water out of the stomata in their leaves at a different rate in every environment. The amount of transpiration is affected by the environment‚ how developed the plant is to not lose as much water‚ the surface area of the leaves‚ and how affected the plant is by its environment (Von Bargen). For this experiment‚ the plant we used was (Viola tricolor subsp.

BGY 2001 CONCEPT OF BIOLOGY Laboratory Report PRACTICAL 8 TRANSPIRATION Tittle: Transpiration Objectives: 1. To measure transpiration rates by using photometer. 2. To determine the factors that influences the rate of water loss from a plant through transpiration Introduction: Most of the water a plant absorbs is not used for a plant’s daily functioning. It is instead lost through transpiration‚ the evaporation of water through the leaf surface and stomata‚ and through guttation

Transpiration Formal Lab Report By Jessica Tran Introduction When water is transported from the roots to the mesophyll cells in the leaves‚ it is evaporates out the stomates‚ called transpiration‚ to create a lower osmotic potential. Osmotic potential is the part of the water potential of a tissue that results from the presence of solute particles. Even though the stomates open to release water‚ it also brings in carbon dioxide to produce sugar and oxygen through a process of photosynthesis
Premium Plant physiology Osmosis Xylem
HYPOTHESIS 1: Plants transpire the most when the environment has light and less humidity JUSTIFICATION: Water evaporates more readily because light stimulates the opening of the stomata and photosynthesis would occur. HYPOTHESIS 2: Transpiration would occur the second most when there’s light and lots of humidity. JUSTIFICATION: The light would allow photosynthesis to occur and the stomata to open but little if any diffusion of water out the leaf would occur. HYPOTHESIS 3: Plants transpire

Transpiration Lab Write-up. Introduction Transpiration is the evaporation of water from plants. It’s not simply a hazard of plant life but it’s the engine that pulls water from the roots to cool the leaf and supply photosynthesis. The concentration of water vapor in the atmosphere is lower than that in the leaf. Because of this difference‚ water vapor diffuses from the spaces of the leaf‚ through the stomata in the epidermis. Stomata are in the lower epidermis; the lower surface receives less

Transport in Plants Introduction In this lab experiment‚ we set out to examine the different transpiration rates of a plant system in certain environments. Water is transported in a plant by the process of transpiration‚ which is the loss of water through evaporation from the surface of leaves. The stomata in leaves are responsible for the diffusion of water vapor. Transpiration brings water upward through the xylem in the plant. There are certain factors that can affect transpiration rates in

study the transpiration of a leafy shoot using the bubble potometer * Materials and apparatus: * Bubble potometer * Leafy shoot * Scissors * Basin with water * A fan * Plumbing tape * Method: Normal Condition: 1. The bubble potometer was filled with water. 2. The stem of a leafy shoot was cut under water. 3. The bottom of the stem was wrapped by plumbing tape. 4. The stem was fitted onto the photometer under the water. 5. The plant was allowed

Transpiration and Leaf Resistance By: Bernina Berber Introduction Transpiration is a part of the water cycle process‚ and it is the loss of water vapor from parts of the plants. It is a process similar to evaporation. Evaporation and diffusion cause the plant tissue to have negative water potential. If you were to compare transpiration it would be like saying it is close to sweating (but in plants)‚ especially in leaves but also in stems‚ flowers and roots. Stomata are dots with openings on
