Plants show flower in specific season of summer and winter.

Make a table showing organ specific and tissue-specific manifestation of diseases.

Plants which behave as mesophytes in rainy season and xerophytes in summer are:

Pendulum clocks may run slow in summer and fast in winter .Why?

A plant with red flowers was crossed with another plant with yellow flowers. If F_1 showed all flowers orange in colour, explain the inheritance.

A habitat with long severe winter and growing season of a few months of Summer forms

Define growing season and flowering season.

Transfer of pollen grains from the anther of flower of one plant to stigma of flower of another plant is called

Two Antirrhinum plants, one with red flowers and the other with white flowers were crossed. Show the possible genotypes and phenotypes of the progeny of F_1 and F_2 generations using the Punnette square. Explain the pattern of inheritance.

In monohybrid cross of red and white flower, Mendel got only red flower. On setting the F_1 plants having red flower he got both plants with red and white flower. Explain the basis of using RR and rr symbols to represent the genotype of plants of parental generation.
