Having a comprehensive grasp of the ICSE Class 10 Biology Syllabus 2024-25 is essential for any student who is getting ready for the ICSE Class 10 Board Exams. The syllabus establishes the basis for the course and enables students to comprehend the concepts they should learn and the educational goals they need to reach. This article will delve into the ICSE Class 10 Biology Syllabus for the 2024-25 academic year.
The ICSE Class 10 Biology Syllabus is divided into two parts: Theory and Practical. The Theory paper carries 80 marks, while the Practical paper carries 20 marks. The Theory paper is further divided into four parts: Sections 1 and 2.
Section I carries 40 marks, all questions are compulsory, and it mainly contains short answer questions on the entire syllabus.
Section II carries 40 marks, which contains six questions and students are required to answer any four out of six questions.

The Practical paper assesses the student's practical skills in Biology. The ICSE Class 10 Biology Syllabus will help you prepare for the exam which consists of experiments based on the syllabus and carries a total of 20 marks. The experiments include:
Study of the external morphology of the cockroach.
Analysis of the internal structure of the earthworm.
Identification of tissues in animals and plants
Study of the mitotic and meiotic stages of cell division.
Observation of stomata in plants.
Analysis of the rate of respiration in germinating seeds.
The ICSE Class 10 Biology Syllabus covers a wide range of topics that are important for students to understand. The topics covered in the syllabus are as follows:
The cell theory is one of the fundamental principles of biology, which states that all living organisms are composed of one or more cells, that cells are the basic unit of structure and function in living organisms, and that all cells come from pre-existing cells. This theory was proposed by Matthias Schleiden and Theodor Schwann in the early 19th century and was later refined by Rudolf Virchow.
The structure of a cell can vary depending on its function, but all cells share some common features. The plasma membrane is a phospholipid bilayer that surrounds the cell and regulates the movement of materials in and out of the cell. The cytoplasm is the region within the plasma membrane that contains various organelles, including the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, lysosomes, and peroxisomes.
The nucleus is the control centre of the cell, containing the genetic material in the form of DNA. The mitochondria are the energy factories of the cell, producing ATP through cellular respiration. The endoplasmic reticulum is involved in protein synthesis and lipid metabolism, while the Golgi apparatus is responsible for the processing and sorting of proteins. Lysosomes and peroxisomes are involved in the breakdown of waste materials and detoxification, respectively.
Cell division is the process by which a single cell divides into two or more daughter cells. This process is essential for growth and repair in multicellular organisms. There are two types of cell division: mitosis and meiosis. Mitosis is the process by which a cell divides into two identical daughter cells, while meiosis is the process by which a cell divides into four daughter cells with half the number of chromosomes.
There are two main types of cells: prokaryotic and eukaryotic.
Prokaryotic cells are simple cells that lack a nucleus and other membrane-bound organelles. They are typically found in bacteria and archaea. Eukaryotic cells, on the other hand, are more complex cells that have a nucleus and other membrane-bound organelles. They are found in all other forms of life, including plants, animals, fungi, and protists
Photosynthesis is the process by which green plants and some other organisms convert light energy into chemical energy in the form of glucose. This process takes place in the chloroplasts of plant cells and involves the absorption of light by pigments such as chlorophyll. The chemical reactions of photosynthesis produce oxygen as a byproduct.
Respiration is the process by which cells convert glucose into ATP, which is the primary energy source for cellular activities. This process takes place in the mitochondria of cells and involves the breakdown of glucose through a series of chemical reactions. The chemical reactions of respiration produce carbon dioxide and water as byproducts.
Transpiration is the process by which plants lose water through their leaves. This process is essential for the transport of water and nutrients from the roots to the rest of the plant. It also helps to cool the plant and maintain a proper balance of water and nutrients.
Excretion is the process by which waste materials are eliminated from the body. In plants, waste materials are eliminated through transpiration and the shedding of leaves and other parts. In animals, waste materials are eliminated through various organs, including the kidneys, lungs, and skin.
The digestive system is responsible for breaking down food into nutrients that can be absorbed by the body. It consists of various organs, including the mouth, oesophagus, stomach, small intestine, large intestine, and liver.
To succeed in the ICSE Class 10 Biology Syllabus, students must follow a systematic study plan and practice regularly. They must make notes while studying and revise the topics regularly to ensure that they have a good understanding of the concepts. Students must also solve previous year's question papers and sample papers to understand the exam pattern and the type of questions asked in the exam.
