Science General Knowledge Questions for All Ages
1. What is the difference between a plant and an animal cell? Plant cells have a cell wall, chloroplasts, and a large central vacuole, while animal cells do not. Plant cells are rectangular, while animal cells are more irregularly shaped. Both types of cells have a nucleus, mitochondria, and other organelles, but plant cells also contain extra structures that allow them to perform photosynthesis and store water more efficiently.
2. How do vaccines work to protect against diseases? Vaccines contain a small amount of a weakened or inactive version of a virus or bacteria that causes a specific disease. When a person is vaccinated, their immune system is exposed to these antigens and creates antibodies to fight off the pathogen. If the person is exposed to the actual disease in the future, their immune system will recognize it and be able to mount a faster and more effective response, preventing the person from getting sick or reducing the severity of the illness.
3. What is the process of photosynthesis and why is it important for life on Earth? Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to produce glucose (sugar) and oxygen. This glucose is used as energy for the plant to grow and carry out cellular functions, while the oxygen is released into the atmosphere, which is essential for all aerobic organisms, including humans, to breathe. Without photosynthesis, plants would not be able to survive, and there would be a lack of oxygen in the atmosphere, making it impossible for many living things to exist on Earth.

Brush Up on Your Science General Knowledge: Questions and Answers
1. What is the process by which plants make their food using sunlight?
Photosynthesis is the process by which plants use sunlight to produce their food. In this process, plants use the energy from sunlight to convert carbon dioxide and water into glucose, a type of sugar that provides the plant with energy. Photosynthesis takes place in the chloroplasts of plant cells and is essential for the survival of plants and other organisms that rely on plants for food.
2. What is the smallest unit of matter that retains the properties of an element?
The smallest unit of matter that retains the properties of an element is an atom. Atoms are made up of protons, neutrons, and electrons. Protons have a positive charge, neutrons have no charge, and electrons have a negative charge. The number of protons in an atom determines the element it represents, while the number of neutrons and electrons can vary.
3. What is the Earth’s natural satellite called?
The Earth’s natural satellite is called the Moon. The Moon orbits the Earth and is about one-sixth the size of the Earth. The gravitational pull of the Moon is responsible for the tides on Earth. The Moon also plays a role in stabilizing the Earth’s rotation and provides the only natural satellite for humans to study up close.
