PSEB Class 10 Life Processes Practice

Life Processes is an important Class 10 Science chapter that explains the basic functions necessary for living organisms to survive. These processes include nutrition, respiration, transportation, and excretion. Even when an organism is at rest, these life processes continue.

Questions from this chapter may ask students to identify types of nutrition, understand photosynthesis, revise human digestion, compare aerobic and anaerobic respiration, understand blood circulation, identify the roles of xylem and phloem, and explain how kidneys and nephrons remove waste from the body.

Use this 20-question practice test before broader Class 10 Science revision. After completing the test, review every explanation carefully and repeat the test after revising weak areas such as photosynthesis, digestion, respiration, transportation, and excretion.

What to Review for Life Processes

Focus on nutrition, respiration, transportation, excretion, and their organs.

Nutrition and Digestion

Review autotrophic nutrition, heterotrophic nutrition, photosynthesis, stomata, chlorophyll, human digestive system, saliva, stomach, small intestine, bile, pancreatic juice, and villi.

Respiration and Transportation

Practice aerobic respiration, anaerobic respiration, breathing, lungs, alveoli, haemoglobin, heart, arteries, veins, capillaries, double circulation, and transport in plants.

Excretion and Plant Transport

Revise xylem, phloem, transpiration, translocation, kidneys, ureters, urinary bladder, urethra, nephron, urine formation, selective reabsorption, and dialysis.

Key Life Processes Concepts to Remember

Before repeating the test, make sure you can connect each life process with its function and related organs. Most questions become easier when you first decide whether the process is related to obtaining food, releasing energy, transporting materials, or removing waste.

Common Mistakes in Life Processes Questions

Life Processes questions often involve organs, functions, and pathways. When checking your result, see whether one of these common mistakes affected your answer:

  • Confusing nutrition with respiration
  • Forgetting that photosynthesis occurs in green plants
  • Forgetting that chlorophyll traps sunlight
  • Confusing stomata with chloroplasts
  • Thinking oxygen is a raw material for photosynthesis
  • Forgetting that saliva starts starch digestion
  • Confusing stomach digestion with small intestine digestion
  • Forgetting that bile helps in fat digestion
  • Confusing aerobic and anaerobic respiration
  • Forgetting that alveoli are sites of gas exchange
  • Confusing arteries with veins
  • Thinking xylem transports food
  • Thinking phloem transports only water
  • Confusing excretion with egestion
  • Forgetting that kidneys are part of the excretory system
  • Confusing nephron with neuron

Life processes are the basic functions that living organisms perform to maintain life, such as nutrition, respiration, transportation, and excretion.

Photosynthesis is the process by which green plants prepare food using carbon dioxide, water, chlorophyll, and sunlight.

Respiration is the process by which food is broken down to release energy needed for life activities.

Kidneys filter blood and remove nitrogenous waste products from the body in the form of urine.
