31) How do Anther Carpel Pistil Pollen Seed flowe ring plants ng plants reduce resource competition between parent and progeny 32) The desired pollinating specles probably would Yellow petals Red petals Green petals Sweet scents Putrid scents not be attracted by - e flowers pollinated? 33) The flowers of a local plant species emit scents at night. How are these flowers pollin Rain at night Self-pollination at night Animals at night Wind at night None of the above 34) Which characteristic would be expected for the seeds of a flowering plant species dispersed by wind? Red fruit tissue No fruit tissue Relatively large size Nutritious fruit tissue Purple fruit tissue 35) A local flowering plant species surrounds its seeds with fruit tissue. These seeds are dispersed by Ocean currents Mechanical ejection Animal species Wind currents River currentsExplanation / Answer
Please find the answers below:
Answer 31: Choice 5: The parent and the progeny have reproduction as a common link which join them to each other. During the course of reproduction, the progeny have to compete with the parent generation for food and othe resources. Thus, the only strategy available for the parent generation is to limit the number of seeds produced and developing a strategy that limits the extent of germination of these seeds. For example, generation of light weight seeds will require wind-blowing in order to promote germination. Thus, the seeds help in developing natural strategies to limit mutual competetion for resources between the parent and progeny.
Answer 32: Choice 5 (Putrid or unpelasant smell will attract only non-pollinating insects and bacteria/fungi which dwell upon decaying organic matter. This will not help in cross-pollination)
Answer 33: Choice 3 (The nocturnal animals dwell actively during night and get attracted towards the sweet-smelling plants and thus proximate them. This helps in cross-pollination during night)
Answer 34: Choice 2 (If a plant requires to be pollinated by wind, the seeds must be very light weight in size. This can be possible only if the seeds are not covered by fruits or the fruit-pulp decays/dries up with time.)
Answer 35: Choice 3 (The fruiting plants are highly palatable to animals and birds which eat them and disperese the seeds around the nearby locations. This helps the plants to germinate their seeds)
