Name the type of respiration in which the end products are: (a) C2H5OH and CO2 (b) CO2 and H2O (c) Lactic acid Give one example of each case where such a respiration can occur.

The end products are C2H5OH and CO2, hence it is anaerobic Example: Yeast The end products are CO2 and H2O, hence it is the aerobic Example: Humans The end product is lactic acid, hence it is the anaerobic Example: Muscles in human beings

BiologyClass 10ICSE

What type of respiration takes place in human muscles during vigorous physical exercise? Give the reason for your answer.

Anaerobic respiration takes place in human muscles during vigorous physical exercise. During exercise our body needs more energy and aerobic respiration is not sufficient. Hence muscles start anaerobic respiration to meet the energy needs.

BiologyClass 10ICSE

Name the final product/products obtained in the anaerobic respiration, if it takes place: (a) In a plant (like yeast). (b) In an animal tissue (like muscles).

Ethanol, carbon dioxide and energy are the final products during anaerobic respiration in plants (like yeast). Lactic acid and energy are the final products during anaerobic respiration in an animal tissue (like muscles).

BiologyClass 10ICSE

Explain why, a land plant may die if its roots remain waterlogged for a long time.

The roots of plant cannot respire if they remain waterlogged for a long time. The water molecules block the stomatal pores present on the leaves and makes the plant difficult to respire, which leads to death of the plant.

Fill in the following blanks with suitable words: (a) The organs of respiration in man are the (b) The actual exchange of gases takes place in the of the lungs. (c) in the lungs provide a very large surface area for gaseous exchange. (d) Yeast undergoes respiration whereas Amoeba undergoes.respiration. (e) Gills are the breathing organs in

The organs of respiration in man are the lungs. The actual exchange of gases takes place in the alveoli of the Alveoli in the lungs provide a very large surface area for gaseous Yeast undergoes anaerobic respiration, whereas Amoeba undergoes aerobic Gills are the breathing organs in aquatic animals.

BiologyClass 10ICSE

State whether the following statements are true or false: (a) During respiration, the plants take CO2 and release O2. (b) Energy can be produced in cells without oxygen. (c) Fish and earthworm exchange gases during respiration in the same way.

False During respiration, the plants take oxygen and release carbon dioxide. The exchange of gases take place the stomatal pores present on leaves of the plant. True Energy can be produced in the cells even without oxygen. Anaerobic respiration also produces energy and uses glucose, but it produces less energy and does not require oxygen. False Fish breathe through the organ called gills and earthworms breath

BiologyClass 10ICSE

In the lungs: (a) What substance is taken into the body? (b) What substance is removed from the body?

Oxygen is taken into the The oxygen is transported to all parts of the body through blood. Carbon dioxide is removed from the The impure blood containing carbon dioxide is brought back to the lungs and then exhaled.

BiologyClass 10ICSE

What organs are attached to the two bronchi?

The two lungs are attached to the two bronchi. The lungs are a pair of spongy, air-filled organs located on either side of the chest. These are the vital organs of the respiratory system.

BiologyClass 10ICSE

What is the other name of the wind-pipe?

Wind-pipe is also known as a trachea. The trachea, is a cartilaginous tube that connects the larynx to the bronchi of the lungs which allows the passage of air.

BiologyClass 10ICSE

What is the name of tiny air-sacs at the end of smallest bronchioles in the lungs?

Alveoli are the tiny air sacs at the end of smallest bronchioles in the lungs. These are tiny, balloon- shaped air sacs sit at the very end of the respiratory tract and are arranged in clusters throughout the lungs. Gas exchange takes place in the alveoli of the lungs.

BiologyClass 10ICSE

Where in the lungs does gas exchange take place?

Gas exchange takes place in the alveoli of the lungs. These are tiny, balloon-shaped air sacs sit at the very end of the respiratory tract and are arranged in clusters throughout the lungs.

BiologyClass 10ICSE

Name the red pigment which carries oxygen in blood.

Hemoglobin is the red pigment that is present in red blood cells. The main purpose of hemoglobin is to transport oxygen to all parts of the body from lungs.

BiologyClass 10ICSE

Which gases are exchanged in your lungs?

Carbon dioxide and oxygen are exchanged in the lungs. Lungs purifies the inhaled air and transport to all parts of body. The impure air containing carbon dioxide is exhaled.

BiologyClass 10ICSE

The trachea divides into two tubes at its lower end. What is the name of these tubes?

The trachea divides into two tubes at its lower end, which are known as bronchi. These are the airways that lead from the trachea into the lungs, and then branch into smaller bronchioles.

BiologyClass 10ICSE

Where does the blood absorb oxygen in the human body?

Blood absorbs the oxygen in the small organelles also known as Alveoli (singular name is Alveolus). These are present in the lungs.

BiologyClass 10ICSE

Name two animals which breathe through gills.

Aquatic animals like sharks and tadpoles breathe through gills. Aquatic animals may breathe air or extract oxygen that dissolved in water through specialized organs called gills, or directly through the skin.

BiologyClass 10ICSE

Name the organs of breathing in fish.

In fish, gills are the organs of breathing. Aquatic animals may breathe air or extract oxygen that dissolved in water through specialized organs called gills, or directly through the skin.

BiologyClass 10ICSE

Name an animal that depends on simple diffusion of gases for breathing.

Spongilla depends on simple diffusion of gases for breathing.

BiologyClass 10ICSE

Name an animal which absorbs oxygen through its moist skin.

Frog absorb oxygen through their moist skin. These come under the class of amphibians. Almost all amphibians have thin, moist skin that helps them breathe.

BiologyClass 10ICSE

Out of photosynthesis and respiration in plants, which process occurs: (a) all the time? (b) Only during daytime?

Respiration occurs all the Respiration is the process through which plants breathe and it happens all the time. Photosynthesis occurs only at daytime as it can take place only in the presence of
