Life Processes Class 10 MCQ PDF Download Term 1




Introduction




Life processes are the basic functions that are performed by living organisms to maintain their life. They include nutrition, respiration, transportation, and excretion. These processes are essential for the survival, growth, and development of living beings. In this article, we will learn about the different types of life processes, their importance, and how to practice multiple-choice questions (MCQs) on them for class 10 term 1 exam.

What are life processes?




Life processes are the physical and chemical activities that take place in living cells or organisms. They involve the intake, conversion, utilization, and removal of materials and energy. Some examples of life processes are photosynthesis, digestion, breathing, circulation, and excretion.


Why are life processes important for living organisms?




Life processes are important for living organisms because they enable them to:


  • Maintain their internal environment or homeostasis



  • Obtain and use energy for various activities



  • Grow and repair damaged tissues



  • Respond to stimuli or changes in the environment



  • Reproduce and pass on their genetic information



Types of life processes




The four main types of life processes are nutrition, respiration, transportation, and excretion. Let us understand each of them in detail.


Nutrition




Nutrition is the process of obtaining and using food by living organisms. It involves two steps:


  • Ingestion - taking in food from the environment



  • Digestion - breaking down food into simpler substances that can be absorbed by the cells



Nutrition can be classified into two types based on the source of food:


Autotrophic nutrition




Autotrophic nutrition is the process of making food by using light or chemical energy. Autotrophs are organisms that can synthesize their own food from simple inorganic substances like carbon dioxide and water. Examples of autotrophs are green plants, algae, and some bacteria. They perform photosynthesis or chemosynthesis to produce organic compounds like glucose.


Heterotrophic nutrition




Heterotrophic nutrition is the process of obtaining food from other organisms or organic sources. Heterotrophs are organisms that cannot make their own food and depend on other living or dead matter for nourishment. Examples of heterotrophs are animals, fungi, and most bacteria. They perform different modes of feeding like holozoic, saprophytic, parasitic, or symbiotic.


Respiration




Respiration is the process of releasing energy from food by breaking it down into simpler substances. It involves two steps:

  • Oxidation - combining the broken down substances with oxygen to release energy, carbon dioxide, and water



Respiration can be classified into two types based on the presence or absence of oxygen:


Aerobic respiration




Aerobic respiration is the process of releasing energy from food by using oxygen. It is the most efficient and common mode of respiration in most living organisms. It takes place in the mitochondria of the cells and produces a large amount of energy (36 ATP molecules) per glucose molecule. The equation for aerobic respiration is:


C6H12O6 + 6O2 6CO2 + 6H2O + Energy


Anaerobic respiration




Anaerobic respiration is the process of releasing energy from food without using oxygen. It is a less efficient and rare mode of respiration in some living organisms. It takes place in the cytoplasm of the cells and produces a small amount of energy (2 ATP molecules) per glucose molecule. The end products of anaerobic respiration vary depending on the type of organism. For example, in yeast and some bacteria, anaerobic respiration produces ethanol and carbon dioxide. In some animal cells, anaerobic respiration produces lactic acid. The equations for anaerobic respiration are:


In yeast and some bacteria:


C6H12O6 2C2H5OH + 2CO2 + Energy


In some animal cells:


C6H12O6 2C3H6O3 + Energy


Transportation




Transportation is the process of moving substances from one part of the body to another or from one cell to another. It involves two components:


  • Circulatory system - a network of vessels that carry blood or sap throughout the body or plant



  • Lymphatic system - a network of vessels that collect excess fluid from the tissues and return it to the blood stream



Transportation can be classified into two types based on the type of organism:


Transportation in animals




Transportation in animals is the process of moving substances like oxygen, carbon dioxide, nutrients, hormones, and wastes through blood. Blood is a fluid connective tissue that consists of plasma (liquid part) and blood cells (solid part). Blood cells include red blood cells (carry oxygen), white blood cells (fight infections), and platelets (help in clotting). Blood is pumped by the heart through arteries, veins, and capillaries. The heart has four chambers: two atria and two ventricles. The circulation of blood can be divided into two types: systemic circulation (between heart and body) and pulmonary circulation (between heart and lungs).


Transportation in plants




Transportation in plants is the process of moving substances like water, minerals, food, and hormones through sap. Sap is a watery solution that flows in specialized tubes called xylem and phloem. Xylem transports water and minerals from the roots to the leaves. Phloem transports food and hormones from the leaves to other parts of the plant. The movement of sap is driven by osmosis, transpiration, root pressure, and capillary action.
