Is the plant wilted in picture 2?
Is the plant wilted in picture 3?
Homework Answers
THE WILTED PLANT IS PICTURE 3
Wilting occurs when the turgor pressure in plant cells falls towards zero, as a result of diminished water in the cells.during this time the rate of loss of water will be more than the rate of absorption of water.
the epidermis of the leaf is characterised by the presence of small opening called stoma,through which gaseous and water exchnage tookplace. This stoma is protected by GUARD cell.
The opening and closure of stoma is controlled by the guard cell. when water enter the guard cell is will swell up and move away from the stoma resulting in the opening of the stoma.
Ath the time of wilting the amount of water in the plant is very low, so the guard cell cant swell up and it cause the closure of the stoma and protect the plant from further loss of water in the form of evaporation.

Total leaf conductance was measured on two plants. One plant was in Los Angeles where the air temperature was 36 °C and relative humidity was 30%. The other plant was in Miami at an air temperature of 36 ° C and a relative humidity of 85%. If the leaf temperature was 38 ° C and if total leaf conductance was 400 mmol m-2 s-1, and assuming standard atmospheric pressure at sea level, calculate the transpiration rates (in units of mmol...

At first, use the microscope's 10x objective, then switch to the 43x objective. With the 10x objective in place, note the variation in size and orientation of the veins (vascular bundles), which contain the two vascular (conducting) tissues, xylem and phloem. The centrally located largest vein is the midvein. The midvein and...

The weight of fruit in a plant is determined additively by 3 genes. A plant having all recessive alleles has a fruit weight of 2 g. A plant having all dominant alleles has a fruit weight of 8 g. Determine the range of weights (minimum and maximum) for the offspring of the following cross: AA Bb CC x aa Bb Cc 4 – 7 grams 2 – 8 grams 4 – 8 grams 2 – 5 grams
