Class 10th Science Sample Paper Solution - Why is it Essential?

Before delving into the solutions, let's understand the importance of practicing with sample papers. Sample papers serve as a valuable tool for students to assess their understanding of concepts and identify areas that require more attention. By solving sample papers, students can:

1. Familiarize themselves with the exam pattern: Sample papers are designed to mimic the actual exam pattern, enabling students to become familiar with the types of questions and their weightage.
2. Improve time management skills: By solving sample papers within a stipulated time frame, students can develop effective time management skills, which are crucial during the actual examination.
3. Identify weak areas: Through regular practice with sample papers, students can identify their weak areas and take corrective measures to strengthen their understanding of those topics.
   Now that we understand the significance of solving sample papers, let's explore the solutions to some of the common questions you may encounter.

Sample Paper Solution - Question 1

Question: Explain the process of photosynthesis, highlighting the role of chlorophyll.
Solution: Photosynthesis is a vital process in plants, enabling them to convert sunlight, water, and carbon dioxide into glucose and oxygen. The process can be summarized in the following steps:

1. Absorption of sunlight: The first step of photosynthesis involves the absorption of sunlight by chlorophyll, a pigment present in the chloroplasts of plant cells.
2. Conversion of light energy: Chlorophyll utilizes the energy from sunlight to convert carbon dioxide and water into glucose and oxygen. This process takes place in the chloroplasts.
3. Release of oxygen: As a byproduct of photosynthesis, oxygen is released into the atmosphere, contributing to the replenishment of the Earth's oxygen levels.
   The role of chlorophyll in photosynthesis is crucial as it absorbs light energy and initiates the process. Chlorophyll molecules are responsible for capturing photons from sunlight and transferring the energy to other molecules involved in the synthesis of glucose.

Sample Paper Solution - Question 2

Question: What is the law of conservation of energy? Provide an example to illustrate this law.
Solution: The law of conservation of energy states that energy cannot be created or destroyed but can only be transformed from one form to another. The total amount of energy in a closed system remains constant.
To better understand this law, let's consider an example:
Imagine a pendulum swinging back and forth. At the highest point, the pendulum has maximum potential energy, which is then converted into kinetic energy as it moves towards the lowest point. As the pendulum reaches the lowest point, all the potential energy is converted into kinetic energy. The pendulum then swings back, converting kinetic energy back into potential energy. Throughout this process, the total energy of the system remains constant, adhering to the law of conservation of energy.

Sample Paper Solution - Question 3

Question: Differentiate between ruminants and non-ruminants.
Solution: Ruminants and non-ruminants are two distinct categories of mammals that differ in their digestive systems.

1. Ruminants: Ruminants, such as cows and sheep, have a unique digestive system that allows them to extract maximum nutrition from plant-based food. They possess a four-chambered stomach, including the rumen, reticulum, omasum, and abomasum, which work together to break down cellulose through fermentation. Ruminants have the ability to regurgitate partially digested food for further chewing and digestion.
2. Non-ruminants: Non-ruminants, including humans and dogs, possess a simple single-chambered stomach. Their digestive system is less efficient in extracting nutrients from plant material compared to ruminants. Non-ruminants rely on enzymes and acids in their stomach to break down food for digestion.
   Understanding the differences between ruminants and non-ruminants is important in comprehending their dietary requirements and digestive processes.
