In dicot root, cambium develops from secondary meristem. First to happen during secondary growth is
1. cambium becomes active below phloem
2. conjunctive tisse inner to pheloem gets active
3. cambium develops from pericycle opposite to protoxylem
4. a wavy ring of cambium develops.

All of the following are secondary meristems except 1. Intercalary meristems 2. Lateral meristems 3. Inter Fascicular cambium 4. Cork cambium

Read the following four statements (A-D) (A) Both, photophosphorylation and oxidative phoshorylation involve up hill transport of protons across the membrane (B) In dicot stems, a new cambium origanets from the cell of pericycle at trhe time of secondary growth (C ) Stamens in flowers of Gloriosa and Petunia are polyandrous (D) Symbiotic nitrogen-fixers occur in the free-living state also in soil How many of the above statements are right

Read the following four statements (A-D) - (A) Both, photophosphorylation and oxidative phosphorylation involve uphill transport of protons across the membrane - (B) In dicot stems, a new cambium originates from cells of pericycle at the time of secondary growth - (C) Stamens in flowers of Glorisa and Petunia are polyandrous - (D)Symbiotic nitrogen-fixers occurs in free-living state also in soil- How many of the above statements are right?

Go through the following statements (i) The cambium is generally more active on the inner side than on the outer. (ii) The autumn wood is darker and has a higher density than spring wood. (iii) In stem, the secondary xylem shows distinction into protoxylem and metaxylem and occurs in the from of patches. (iv) The tracheids and vessels of the sapwood get plugged by the ingrowth of the adjacent parenchyma cells into their cavities called tyloses. Which of theses are correct ? a. (i), (ii) & (iii) b. (i), (ii) & (iv) c. (i) and (ii) d. (i), (iii) & (iv)
