Suppose all external factors necessary for photosynthesis are available at optimum level , but temperature is as low as `20^(@)C` , how will it effect the rate of photosynthesis.

Text Solution

Verified by Experts

The photosynthesis reaction will proceed at slow speed because enzymatic action slow down . It is an established fact that enzymes act best at a temperature between `25^(@) C " to "35^(@)C` and at low temperature their action slows down and rate of photosynthesis decreases.

Figure shows the effect of light on the rate of photosynthesis. Based on the graph, answer the following questions . (a) At which point /s (A,B or C) in the curve is light a limiting factor ? (b) What could be the limiting factor/ s in region A ? (b) What could be the limiting factor /s in region A ? (c) What do C and D represent the following .

An external pressure P is applied on cube at 0" "^(@)C so that it is equally compressed from all sides. K is the bulk modulus of the material of the cube and alpha is its coefficient of linear expansion. Suppose we want to bring the cube to its original size by heating. The temperature should be raised by

In the atmosphere, carbon dioxide is found in two forms, i.e., ^12CO_2 and ^14CO_2 . Plants absord CO_2 during photosynthesis in presence of chlorophyll, plants synthesise glucose 6CO_2 +6 H_2O rarr C_6H_12O_6 + 6O_2uarr Half life of ^14CO_2 is 5760 years. The analysis of wooden artifacts for ^14C and ^12C gives useful information for determination of its age. All living organisms, because of their constant exchange of Carbon dioxide with the surroundings have the same ratio of C-14 to C-12, i.e. 1.3xx10^-12 . When an organism dies, the C-14 in it keeps on decaying as follows: 6^14Crarr7^14N+(-1)^0e +Energy Thus, the ratio of C-14 and C-12 decreases with the passage of time. We can measure the proportion of C-14 in the remains of dead organism and determine how long ago it died. The method of carbon dating can be used to date anything made or organic matter, e.g., bone, skeleton, wood, etc. Using carbon dating, materials have been dated to about 50,000 years with accuracy. C-14 exists in atmosphere due to:
