Description : (a) Draw a diagram of human respiratory system and label the following: (i) part where air is filtered by fine hair and mucus (ii) part which terminates in balloon - like structures (iii) ... (b) Why is the rate of breathing in aquatic organisms much faster than in terrestrial organisms? -Biology
Last Answer : (a) (b) Quantity of dissolved oxygen is fairly low in water as compared to the amount of oxygen in air. Aquatic organisms therefore have to breath faster than terrestrial organisms to absorb the required amount of oxygen from the water.

Last Answer : Faster rate
Description : Photosynthesis generally takes place in which parts of the plant?
Last Answer : Leaf and other chloroplast bearing parts
Description : During photosynthesis, energy is absorbed by chlorophyll, therefore it is: (a) exothermic reaction (b) endothermic reaction (c) neither exothermic nor endothermic reaction (d) the process takes place in plants only
Last Answer : (b) endothermic reaction

Description : The bulk fixation of carbon through photosynthesis takes place in
Last Answer : The bulk fixation of carbon through photosynthesis takes place in A. Crop plants B. Tropical rain forests C. Ocean D. Both (1) and (2)
Description : The exchange of gases takes place in the leaves through these pores for the purpose of photosynthesis. These pores are called – (1) Guard Cells (2) Stomata (3) Chloroplast (4) None of the above
Last Answer : (2) Stomata Explanation: Stomata are tiny pores present on the surface of the leaves via which exchange of gases takes place in the leaves for the purpose of photosynthesis. However, exchange of gases also occurs across the surface of stems, roots and leaves as well.
Description : Photosynthesis takes place inside plant cells in ______. (1) Ribosomes (2) Chloroplasts (3) Nucleus (4) Mitochondria
Last Answer : (2) Chloroplasts Explanation: In plants, the process of photosynthesis takes place in the mesophyll of the leaves, inside the chloroplasts.
Description : Maximum photosynthesis takes place in— (A) Blue light (B) Red light (C) Violet light (D) Green light
Last Answer : (D) Green light

Last Answer : (b) 15°C – 40°C
Description : What causes a green plant exposed to the light, on only one side, to bend towards the source of light as it grows? (a) Light stimulates plant cells on the lighted side to grow ... Green plants need light to perform photosynthesis. (d) Green plants seek light because they are phototropic.
Last Answer : (b) Auxin accumulates on the shaded side, stimulating greater cell elongation there
