Solutions

S1.Ans. (b)
Sol. The site of cellular respiration is mitochondrion as it involved in generation of energy, (ATP). Nucleus consists of genetic material which is transferred from one generation to another, ribosome helps in protein synthesis and Golgi apparatus helps in glycosylation.

S2.Ans. (a)
Sol. Xylem is responsible for transporting water and various mineral salts. Phloem is responsible for transportation of sucrose, cambium helps in secondary growth which gives rise to xylem and phloem and cortex is a ground tissue present in the plant organ, usually consisting of vascular bundles.

S3.Ans. (b)
Sol. The products of photosynthesis in green plants are made in leaves (mesophyll cells). Sugar molecules are synthesized, which are generally called as photosynthates. Phloem tissue carries these photosynthates to distant plant organs. Unlike conduction in xylem, the transport through phloem is multidirectional.

S4.Ans. (d)
Sol. The gravitational force is a force that attracts any objects with mass. This is called Newton’s Universal Law of Gravitation. The gravitational force on Earth is equal to the force the Earth exerts on you. At rest, on or near the surface of the Earth, the gravitational force equals your weight.

S5.Ans. (c)
Sol. Whether an object will float or sink in a liquid, depends on difference in the densities of the object and liquid.

S6.Ans. (a)
Sol. A ball balanced on a vertical rod is an example of unstable equilibrium.

S7.Ans. (d)
Sol. Tomato is red in colour due to the presence of lycopene pigment found in the chromoplasts.

S8.Ans. (d)
Sol. Psammophytes is a plant that grows in shifting sands, primarily in deserts. They are marked by a number of adaptations which enable them to exist on wind-blown sands for e.g. Haloxylon persicum, Calligonum, Ammondendron, Eremosparton, Smirnowi.

S9.Ans. (b)
Sol. Insectivorous plants are plants that derive some or most of their nutrients from trapping and consuming animals or protozoans, typically insects and other arthropods. They have adapted to grow in places where the soil is thin or poor in nutrients, especially nitrogen.

S10.Ans. (c)
Sol. The production of naked seeds or ovules without fruits is one of the main characteristic features of Gymnosperms. Cycas sp. is a gymnosperm.
