Question
Which specific part of the plant is used to produce
'haploid' plants in tissue culture?Solution
Pollen grains and anthers contain gametic (n) cells rather than somatic (2n) cells. Culturing these results in haploid plants, which are invaluable for plant breeding and creating pure lines.
What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)...
2720.03 ÷ 79.98 x 39.9 = ? + 40.32
√2401 × (√2116 ÷ 23) × 21 ÷ 3 = ?
29.98% of 549.99 = ? - 254.97 + 79.98% of 74.99
What approximate value will come in place of the question mark (?) in the following question?
(1963.33 ÷ 6.5 - 193.99)/? = 753.02 ÷ 26.98
63.981 + 64.001 + 65.08019 + 63.11112 =?
`sqrt(1297)` + 189.99 =?
[(2/3 of 599.77) + (39.69% of 450.14)] ÷ [(5/8 of 399.79) - √120.91] = ?
44.78% of 715.62 + 1785% of 42.98 = ?
