If vegetative growth of the plant takes place but flower production does not occur then what could be the reason for this?
1 Imbalance of hormones
2 Irregular transport of solute
3 Imbalance of sugar in water
4 Photoperiod
Explanation:
Photoperiodism is process that requires exposure to sunlight for certain period of time for flowering.

Bacteria, fungi and lower plants survive in adverse conditions by
1 Formation of thick walled spores
2 Diapause
3 Migration
4 Suspended growth
Explanation:
Certain bacteria, fungi and lower plants produce metabolically inactive forms that can survive intensely adverse conditions unharmed, these are known as spores which are thick walled.

The term 'clone' cannot be applied to offspring formed by sexual reproduction because:
1 Offspring do not possess exact copies of parental DNA
2 DNA of only one parent is copied and passed on to the offspring
3 Offspring are formed at different times
4 DNA of parent and offspring are completely different.
Explanation:
Gametogenesis takes place through meiosis and crossing over takes place during meiosis. Crossing over is responsible for some alteration in genotype. Moreover, fertilization results in gene pools from two different individuals and thus zygote has a somewhat different genotype than both the presents. Hence, the term clone cannot be applied to offspring formed by sexual reproduction.

What is common between apomixis and vegetative reproduction?
1 Both bypass flowering phase
2 Both applicable to dicots only
3 Both occur around the year
4 Both produce progeny identical to parent
Explanation:
In both forms of reproduction the progeny is identical to the parent.

Which mode of reproduction is present in Amoeba ?
1 Binary fission and multiple fission
2 Binary fission and conjugation
3 Binary fission only
4 Multiple fission only
Explanation:
Binary fission is the asexual form of reproduction in which a single celled organisms divides itself into two cells in favourable conditions. Multiple fission is the asexual form of reproduction where the parent Amoeba cells divide to give many daughter cells in unfavourable conditions.
