You have a plant that doen't produce seeds. Explain any two methods of artificial vegetative reproductiopn ofr this plant to propegate.

Explain two vegetative reproduction process in plant.

Name tow plants which have been produced byt erh artificial selection.

A computer producing factory has only two plants T_(1) "and" T_(2) "Plant" T_(1) produces 20% and plant T_(2) produced 80% of the total computers produced. 7% of computers produced in the factory turn out to be defective. It is known that P (computer turns out to be defective, given that it is produced in plant T_(1) = 10 P (computer turns out to be defective, given that it is produced in plant T_(2) )where P(E) denptes the probability of an event E. A computer produced in the factory is randomly selected and it does not turn out to be defective. Then the probability that it is produced in plant T_(2) is

It is known that P (computer turns out to be defective givent that it is produced in plant T_(1)) = 10 P ( computer turns out to be defective given that it is produced in plant T_(2)), where P (E) denotes the probability of an event E. A computer produced in the factory is randomly selected and it does not turn out to be defective. Then the probability that it is produced in plant T_(2) is

You have brought a rose twig your friend's house and planted it in you garden? Discuss the method you have adopted and why? How will you differentiate between the cell division of a somatic cell and a reproductive mother cell on the basis of- nature of chromosome division

Tall plant with round seeds (TTRR) is crossed with dwarf plant having wrinkled seeds (ttrr). F_(1) plants are tall with rounded seeds. Types of gametes produced by them would be

A cross between a red flower bearing plant and a white flower bearing plant of Antirrhinum produced all plants having pink flowers. Work out a cross to explain how this is possible.

In Garden Pea, round shape is dominant over wrinkled shape. A pea plant heterozygous for round shape of seed is selfed and 1600 sedds produced during the cross are subsequently germinated. How many offspring will have parental phenotype

Identify the wrong pair of statements I. Number of stamens in 5 flowers of Allium is equal to those in 5 flowers of Solanum II. The microporangia of Hibiscus and Asparagus are having 80 pollen grains each. Then the ratio of number of pollen grains produced from each stamen of these two plants in 1:1 III. The ratio of number of stamens in the flowers of Pisum and Datura is 2:1 IV. The number of carpels in a flower of Smilax is equal to carpels in cyathium inflorescence.

In the atmosphere, carbon dioxide is found in two forms, i.e., ^12CO_2 and ^14CO_2 . Plants absord CO_2 during photosynthesis in presence of chlorophyll, plants synthesise glucose 6CO_2 +6 H_2O rarr C_6H_12O_6 + 6O_2uarr Half life of ^14CO_2 is 5760 years. The analysis of wooden artifacts for ^14C and ^12C gives useful information for determination of its age. All living organisms, because of their constant exchange of Carbon dioxide with the surroundings have the same ratio of C-14 to C-12, i.e. 1.3xx10^-12 . When an organism dies, the C-14 in it keeps on decaying as follows: 6^14Crarr7^14N+(-1)^0e +Energy Thus, the ratio of C-14 and C-12 decreases with the passage of time. We can measure the proportion of C-14 in the remains of dead organism and determine how long ago it died. The method of carbon dating can be used to date anything made or organic matter, e.g., bone, skeleton, wood, etc. Using carbon dating, materials have been dated to about 50,000 years with accuracy. C-14 exists in atmosphere due to:
