1. Import substitution means?
a. Opening up of the industry of a country to outside competition
b. Protecting the industry of a country from outside competition
2. Consider following statements regarding photosynthesis?
a.CO2 and H2O are converted to sugar (CH2O) and oxygen (O2) in the presence of light
b. Only CO2 is converted to sugar (CH2O) and oxygen (O2) in the presence of light
c. CO2 is converted to sugar and oxygen (O2) in the presence of light
Which of the above statements are true?
3. What is the difference b/w respiration and transpiration?
4. Consider the following statements regarding photosynthesis
a. There are 3 variants of photosynthesis namely C3, C4 and CAM
b. C3 happens in plants which grow in dry and arid conditions where as C4 and CAM occur in plants which grow in wet conditions
which of them are true?
5. What does carbon sequestration mean?
6. Carbon capture and storage (CCS) is an important technique of carbon sequestration? what is done in this process?

3.Respiration - digestion of sugar in plants for energy. Transpiration - loss of water through leaves
4.
5.Storing CO2 for a longer period!
Transpiration serves three essential roles:
DeleteMovement of minerals up from the root (in the xylem) and sugars (products of photosynthesis) throughout the plant (in the phloem). Water serves as both the solvent and the avenue of transport.
Cooling – 80% of the cooling effect of a shade tree is from the evaporative cooling effects of transpiration. This benefits both plants and humans.
Turgor pressure – Water maintains the turgor pressure in cells much like air inflates a balloon, giving the non-woody plant parts form. Turgidity is important so the plant can remain stiff and upright and gain a competitive advantage when it comes to light.
1. import substitution=Protecting not opening up
Delete2.a
3.transpiration=loss of water through leaves (stomata)
respiration=breakdown of sugars into energy
sounds similar but not at all related
4. Imp topic. Read more on this.
C4, CAM= effective, even in dry climates these plants can survive eg: MIllets, succulents
C3=rice and wheat, need high water for photo synthesis
5. Imp. Carbon sequestration= removal of CO2 from atmosphere
6. CCS is one such technique where CO2 is stored underground! search for other means of carbon sequestration. Very Imp topic
