Cells and Tissues

The first chapter of the ICSE syllabus of biology class 7 introduces the concepts of cells and tissues. These topics form the fundamental platform for the living system present on this planet. The students will learn the properties of the cell and several exciting features of it. The students will know about the cell organelles, their properties, and function. They will also know the differences between an animal and a plant cell. They will also be trained to make diagrams of different kinds of cells.  


In this segment of class 7th biology ICSE syllabus, the students will learn several exciting concepts about plants. They will learn about how plants extract resources from their surroundings and make their food by photosynthesis. They will learn about the different parts of the plants’ bodies and the functions performed by each of them. They will also know about some diseases that plants suffer from. They will learn about the plant’s contribution to the ecosystem. The students will learn about a variety of plants in this chapter. 


In this chapter, the students will learn about the different kinds of animals found in this world. They will have a brief idea about the organ systems of the animals in brief. They will learn the basic differences between a plant and an animal. The students will be provided with an introductory understanding of the impact of climate on various animals found in a place. 


The concept of microorganisms might prove to be new to the students, and therefore, an introductory approach is taken for microorganisms in this syllabus. The students will learn about different bacterias, viruses, protozoa, etc., their shape, mode of transmission, and effect. They will learn about the good microbes and the pathogenic microbes. The students will also learn about the different diseases caused by microbes upon infection in humans.


In this part, the students will learn about the different food components that we eat every day. They will be introduced to individual nutrients and how they affect our bodies, along with the concept of a balanced diet. The students will be taught about the ill effect of some food components as well. 

Our Environment

In this part, the students will know about the relationship every animal has with its environment. They will also learn about symbiosis, the food chain, the food web, and the food pyramid. Finally, they will understand the need to contribute to nature to maintain the ecosystem’s balance and harmony.

Why Vedantu?

ICSE Class 7 Biology syllabus has been adequately designed to include introductory notes about essential biology concepts. The students will find it understandable and exciting as they start scoring high marks in any Biology examination.  

FAQs on ICSE Syllabus for Class 7 Biology

1. Give an overview of allergy or hypersensitivity mentioned in ICSE Syllabus for Class 7 Biology 2024-25 Examination.

Although our immune system defends us from infections, it can also cause damage to our own cells and tissues. In this unfavorable situation, our immune system behaves as if it were a foreign virus attacking our bodily cells, resulting in a variety of health problems known as Allergy or Hypersensitivity.

Hay fever, asthma, dermatitis, and food allergies are the most frequent allergic reactions. Allergens are chemicals that cause allergic reactions. Pollen, for example, or household dust. Mouth, nose, and skin are the entry points for allergens.

Allergy symptoms vary depending on where part of the body the allergens contact. The following are a few signs and symptoms: -Coughing, itching, fever, and watery eyes.

2. What are neurons according to the ICSE Syllabus for Class 7 Biology 2024-25 Examination?

A neuron, often known as a nerve cell, is made up of three parts:

  • Dendrites - receive nerve impulses from sensory receptors or from other neurons.

  • Dendrite input is processed by the cell body.

  • Axon–this nerve carries impulses away from the body.

Neurons are classified into three categories based on their function in nerve impulse propagation.

  • Sense neuron – transmits nerve impulses from sensory organs to the brain.

  • Motor neurons – sends nerve impulses from the central nervous system to the body's effector organs.

  • Relay neuron - establishes a connection between other neurons (intermediate neurons)

3. Give an overview of the excretory system according to ICSE Syllabus for Class 7 Biology 2024-25 Examination?

Excretion is the process of removing waste or nitrogenous compounds from the body since they are harmful and can create serious problems in the human body if they build up. The consequence of the body's metabolism is excretory products. Organs that aid in waste disposal include:

  • Skin – sweat glands eliminate salt, excess water, urea, and other waste products.

  • Lungs– are in charge of removing gaseous waste from the body during respiration.

  • Large intestine– assists in the removal of solid waste via anus.

  • Kidney– urinary elimination of nitrogenous waste such as urea.

It regulates the volume and composition of bodily fluids as well as the clearance of nitrogenous waste. A pair of kidneys, bean-shaped and weighing roughly 150 grams, are found in the human body. The nephron is the functional and structural unit of the kidney; each kidney includes between 800,000 and 1000,000 nephrons.

4. What is the significance of the excretory system mentioned in ICSE Syllabus for Class 7 Biology 2024-25 Examination?

The significance of the excretory system is given below:

  • The importance of the excretory system - When the excretory system fails, waste products build up, causing problems with osmoregulation, ionic regulation, acid-base balance, and eventually mortality.

  • Urine is a translucent yellowish aqueous fluid with a strong odor. Ammonia, uric acid, creatinine, and hippuric acid make up the majority of it. In a typical 24-hour period, 800 mL to 1500 mL of urine is produced. Waste products will get collected in the body if the volume is less than 500 ml each day.

5. Give a brief overview about respiration mentioned in ICSE Syllabus for Class 7 Biology 2024-25 Examination

Breathing and oxidation of food in cells are both part of respiration. Respiration is divided into three stages: Food has been depleted. Energy is generated. Oxygen is inhaled and CO2 is expelled via a gas exchange (breathing). Food can be oxidized in the presence or lack of oxygen, resulting in two forms of respiration: 



In the presence of oxygen, aerobic respiration occurs. Glucose is totally broken down into Co2 and H2OEnergy is stored in the form of ATP.

Anaerobic respiration occurs when there is no oxygen available. Glucose is broken down into carbon dioxide (CO2) and ethanol, which releases energy. Yeast and other microorganisms are commonly affected. To get free study materials, access the Vedantu website.
