The student who measured water absorption would not obtain reliable results because the water absorbed by a plant can be required to replace that lost by transpiration‚ not just photosynthesis. Plants require most of the water they absorb to replace water lost by transpiration‚ not metabolism. 5. (a) Light compensation point (CO2 uptake = CO2 evolution). (b) Point A represents the light intensity at which the rate that CO2 is fixed into a carbohydrate is equal to

Gaseous exchange and transport Movement of chemicals in plants and animals -Chemicals that are being moved into the body‚ within the body or out of the body are gases‚ this movement is known as gaseous exchange. -The gases being moved in our out of the body need to move across the surface area of the body‚ in most cases a special surface area has been developed. -The surface that the gases cross is called the respiratory surface and the gases move across this surface by the process of diffusion

with groundwater and atmospheric water. - Non-saline surface water is replenished by precipitation and by recruitment from ground-water. It is lost through evaporation‚ seepage into the ground where it becomes ground-water‚ used by plants for transpiration‚ abstracted by mankind for agriculture‚ living‚ industry etc. or discharged to the sea where it becomes saline. - A watershed is an area of land that drains all the streams a rainfall to a common outlet such as out flow of a reservoir‚ mouth of

Living matters are organisms that possess the fundamental characteristics of life. This includes movement‚ respiration‚ sensitivity‚ growth‚ reproduction‚ excretion‚ and nutrition. First off‚ every single living matter is capable of movement. For instance‚ animals can move according to their will; they can change position and transfer from one place to another. Although this trait may not be as noticeable in plants‚ they also show little movements such as when leaves turn towards the direction
