Explanation

The NCERT text states: 'During the course of evolution, the eggs of the parasitic bird have evolved to resemble the hostâ€™s egg in size and colour to reduce the chances of the host bird detecting the foreign eggs and ejecting them from the nest.'

Cuscuta is an example of a plant parasite. What is a key feature that allows it to be parasitic?

A. It produces excessive chlorophyll. B. It has abundant leaves to photosynthesize efficiently. C. It has lost chlorophyll and leaves, deriving nutrition from a host plant. D. It forms a mutualistic relationship with its host.

Explanation

The NCERT text describes Cuscuta as having 'lost its chlorophyll and leaves in the course of evolution. It derives its nutrition from the host plant which it parasitises.'

Which category of protozoan includes parasitic forms that cause diseases like sleeping sickness?

A. Amoeboid protozoans B. Flagellated protozoans C. Ciliated protozoans D. Sporozoans

Explanation

The NCERT text mentions: 'Flagellated protozoans: The members of this group are either free-living or parasitic. They have flagella. The parasitic forms cause diaseases such as sleeping sickness. Example: Trypanosoma.'

Which of the following statements correctly distinguishes gaseous exchange in plants from animals?

A. Plants have specialized organs like lungs for gaseous exchange, while animals lack them. B. Plants exhibit a high rate of gas exchange compared to animals due to their larger surface area. C. Plants do not possess specialized organs for gaseous exchange, relying on structures like stomata and lenticels. D. Animals perform gas exchange only during respiration, whereas plants continuously exchange gases.

Explanation

According to the NCERT text, 'Plants, unlike animals, have no specialised organs for gaseous exchange but they have stomata and lenticels for this purpose.' Animals, on the other hand, typically possess specialized respiratory organs.

Why do plants not require extensive transport of gases from one part to another, unlike larger animals?

A. Because plant cells are less metabolically active than animal cells. B. Each plant part takes care of its own gas-exchange needs. C. The larger size of plants negates the need for long-distance gas transport. D. Plants primarily exchange gases through their roots, eliminating aerial transport.

Explanation

The NCERT states, 'First, each plant part takes care of its own gas-exchange needs. There is very little transport of gases from one plant part to another.' This localized gas exchange minimizes the requirement for extensive transport systems.

Which of the following is NOT a reason why plants can manage without specialized respiratory organs?

A. Each plant part handles its own gas-exchange requirements. B. Plant respiratory rates are significantly lower than those of animals. C. The availability of O2 is always sufficient due to photosynthesis in all plant cells. D. Most living cells in a plant are located close to the surface, facilitating gas diffusion.

Explanation

The NCERT states that 'Only during photosynthesis are large volumes of gases exchanged and, each leaf is well adapted to take care of its own needs during these periods. When cells photosynthesise, availability of O2 is not a problem in these cells since O2 is released within the cell.' However, not all cells, tissues, and organs photosynthesise, meaning that other parts still require oxygen which is not internally produced.

During which process in plants is the availability of O2 not a problem in photosynthetic cells?

A. Transpiration B. Respiration in roots C. Photosynthesis D. Seed germination
