CO, +HCL+H0+ sunlightCOH.0)+ Minute pores in the leaves of plants that regulate the flow of gases to the interior of the leaf are called A. sporophytes 25. B. stoma C. xylemm D. phloem 26. The Gel-ike material between the nucleus and plasma membrane is considered the A. cytoplasm B. cytosol C cytogel D. cytomembrane The larger a cell becomes: A. it's surface area to volume ratio decreases 27. it's surface area to volume ratio increases it's surface area to volume does not change the less efficient it becomes at transporting nutrients across the membrane B. C. D. 28. DNA is usually found in an area of the cell in bacteria called A. nucleus B. nucleolus C. nucleoid D. prokaryotes do not have DNAExplanation / Answer
Ans 20. (d) the reflect green wavelengths of light.
Explaination:- leaves contain chlorophyll a green pigment and hence leaves doesnot absorp the green light and reflect the green light thus they appear green in colour.
Ans 21. (c) a stack of thyllakoid membrance structures
Explaination:- grana is the stack of thyllakoids which are embedded in the chloroplasts and are just like a stack of disks.
Ans 22. (c) Thyllakoid membrane.
Explaination :- light dependent reactions take place in the thylllakoid membranes
Ans 23. (a) Stroma
Explaination:- The light independent reactions take place in the stroma
Ans 24. (c) 6CO2 + 6H2O + sunlight ----------->C6H12O6 + 6O2
Explaination:- glucose and oxygen is the final product of the photosynthesis.
Ans 25. (b) stoma
Explaination:- stoma also called as stomata are the small pores found on and below the surface of leaves essential for gaeous exchange.
Ans 26. (a) cytosol
Explaination:- is a jelly like material foung around the nucleus upto the plasma membrane into which the organalles are present. sometimes we often confuse cytoplasm as cytosol but cytoplasm is present in the orgalles however cytosol is present only outside the organalles in which they are suspended.
Ans 27. (a) its surface area to volume ratio decreases.
Explaination:- as cells increase the volume increase more than the surface area.
Ans 28. (c) nucleoid
