Is transpiration a necessary evil for plants?

Posted by Amal Fathima 5 years ago

CBSE > Class 10 > Science

3 answers

Priyanshu Gautam 5 years ago

Transpiration is the process of losing extra water to the atmosphere by the leaves of a plant. This leads to a loss of water but also helps in many other processes such as Ascent of Sap(transport of water) and helps in cooling of plant. Hence it is a necessary evil for the plant.

Since 1Ω and 106 Ω are connected in parallel then the equivalent resistance R will be R1=11+1061 R=106+1106 ~ 106106 R=1Ω Equivalent resistance is 1Ω (b) 1Ω and 103Ω and 160Ω are in parallel R1=11+1031+1061 R1=106106+103+1 R1=10000001001001 R=0.999Ω Therefore, equivalent resistance =0.999Ω

Both are true .. since in chemical reaction it involves change in state of matter (all though physical state could be reversed again for ex - when phenolphthalein reacts with base it turns pink and become colourless after sometimes ) as well as interaction between the atoms of the elements. Water gets decompose to produce Hygrogen and oxygen gas during electrolysis .
