Biology 1st Group Lab Report Objective: - To study the transpiration rate of a plant (Gou Qi) by using the bubble photometer. Assumption: - The rate of transpiration is equal to the rate of water uptake of the plant(Gou Qi) . Theory: |Independent Variable |Dependent Variable |Controlled Variable | |The environmental conditions: | Rate of water uptake by transpiration of the

turned out to have the lowest average water loss per day because transpiration requires some type of driving source (light‚ wind‚ etc) for water to travel from the roots of the plant to the stomata of the leafs. 4. How did each condition affect the gradient of water potential from the stem to the leaf in the experimental

AIMS The aim of this experiment was to investigate the effect of temperature rise on the rate of transpiration of a plant (hibiscus) by measuring the plant’s water uptake in a period of time. HYPOTHESIS Transpiration is the process by which plants loses water to the atmosphere from their leaves. Water in the plant is lost to the atmosphere by evaporation. Evaporation of water can occur at any temperature. In the presence of sunlight‚ water in the plants evaporates into the intercellular air

develops many side branches that are not productive. There are new leaves growing in branches. The size of the leaves increases lengthwise and breadthwise. Leaves are oval in shape‚ deeply and palmately 4-7 lobed‚ serrated margins‚ cordate at base‚ leaf tip acute or obtuse. 1.4.3 Flowering stage: In flowering stage yellow dioecious flowers usually appear in 5 to 6 weeks. The male and female flowers are borne separately on the same plant and male flowers normally exceed the females by about 25:1. -

used to stain structures containing starch which is indicated by the color change from brown to reddish-brown or blue-black. The stem‚ leaf‚ and root cross sections all contain starch. The roots stained the darkest meaning starch is stored more in them. Sudan IV dye stains lipids into pink to red color. All cells in a plant tissue contain lipids so the stem‚ leaf‚ and root cross sections are expected to stain red. However‚ only the stem cross section was able to produce a positive result.

Photosynthesis By Sofie Inwood Aim: To determine whether chlorophyll and light is necessary for starch formation. Hypothesis: Chlorophyll and light are both necessary for starch formation. Materials: * 600mL beaker * Access to water * Safety glasses * Bunsen burner * Tripod * Gauze mat * A large white evaporating dish * Scissors and forceps | * Glass stirring rod * Test tube rack * Test-tube (30mm x 180mm) * Methylated spirits * Iodine solution * 100mL

Title: Transpiration Aim: To study the significance of the pattern of stomatal distribution in Coleus and Lucky bamboo leaf Theory: Transpiration is the loss of water vapour from the surface of the plants due to evaporation. Transpiration can help the uptake of water in the xylem due to transpiration pull. During transpiration‚ mesophyll cells lose water continuously to the air space. This decreases the water potential of the mesophyll cells. Water is then drawn from their neighbouring cells

Practical guide to detection and identification of Phytophthora Leaf blight A number of Phytophthora species cause leaf blight. These include: P. infestans on potato and tomato; P. palmivora on a large number of tropical fruit species including rubber‚ durian and macadamia; and P. colocasiae on taro. These blights on leaves are first seen as small flecks but within 3-5 days they expand to produce large lesions. Initially‚ infected tissue is water soaked but becomes necrotic (brown or black) in
