Which of the following are monoecious and dioecious organisms ? (a) Earthworm........... , (b) Chara ........... (c) Marchantia ................ , (d) Cockroach ............. |
|
Answer» (a) Earthworm - Monoecious animal , (b) Chara - Monoecious plant (c) Marchantia - Dioecious plant , (d) Cockroach - Dioecious animals Note In several fungi and plants, terms such as homothallic and monoecious are used to denote the bisexual condition (male and female reproductive structures in the same plant) and heterothallic and dioecious are the terms used to describe unisexual condition (male and female reproductive structures on different plants). But in animals, individuals are either male or female (unisexual) or possess both the reproductive organs (bisexual). |

Is it possible to consider vegetative propagation observed in certain plants like Bryophyllum, water hyacinth, ginger, etc., as a type of asexual reproduction? Give two three resons. |
|
Answer» The formation of new plants from vegetative units (vegetative propagules) such as buds, tubers, rhizomes. etc., is called vegetative propagation (vegetative reproduction). It can be considered as a type of asexual propagation as it involves the production of new individuals.

Assertion: Bacteria divide by mitotic division. Reason : Meiosis occurs in Rhizobium.A. Both Assertion and Reson ae true and Reason is the correct explanation of AssertionB. Both Assertion and Reason are true, but Reason is not the correct explanation of AssertionC. Assertion is true, but Reason is falseD. Assertion is false, but Reason are false |
|
Answer» Correct Answer - C c. Bacteria divide by binary fission, it is a mitotic division, each bacterialcell is divided into two identical daughter cellsl Rhizobium is a nodule forming bacterium present in roots of leguminous plants. These bacteria divide by binary fission. Meiosis does not take place in bacteria because all bacteria are haploid in Nature. They contain only single set of chromosomes. |

Which one of the following generates new genetic combinations leading to mutationsA. Vegetative reproductionB. ParthenougensisC. Sexual reproductionD. Nuclear polyembryony |
|
Answer» Correct Answer - C The sexual reproduction brings about variation through genetic recombination first of all genetic recombination occurs in non-homologous chromosomes during crossing over of pachytene stage in meiotic cell division. Secondly, the random union of gametes also contributes in forming new combinations of characters. in the formation of progenies with new variations. Vegetative reproduction occurs through vegetative parts of organisms (plants). without fertilisation (e.g.frog). |
|
| 138. |
Which of the following statements is not correct?A. Offsprings produced by the asexual reproduction are called cloneB. Microscopic, motile asexual reproductive structures are called zoosporesC. In potato, banana and ginger, the plantlets arise from the internodes presenta in the modified stemD. Water hyacinth, growing in the standing water, drains oxygen from water that leads to the death of fishes |
|
Answer» Correct Answer - C Stastement c is in potato, banana and ginger new lantlets always arise from the nodes of the modified stem. Internodes are area between the two nodes. |

Which one of the following generates new genetic combinations leading to mutationsA. Vegetative reproductionB. ParthenogensisC. Sexual reproductionD. Nucellar polymebryony |
| Answer» Correct Answer - C | |
| 140. |
Which one of the following generates new genetic combinations leading to variation ?A. Vegetative reproductionB. ParthenogenesisC. Sexual reproductionD. Nucellar polyembryony |
|
Answer» Correct Answer - C The sexual reproduction brings about variation through genetic recombinations. First of all, genetic recombination occurs in non-homologous chromosomes during crossing over of pachytene stage in meiotic cell division. Secondly, the random union of gametes also contributes in forming new combinations of characters. Other options a, b and d do not contribute in the formatioinfo progenies with new variations. |
