What is often called the 'Powerhouse of the Cell'?
Explanation: Mitochondria are known as the powerhouse of the cell because they produce energy. The nucleus stores genetic information, ribosomes make proteins, and chloroplasts are involved in photosynthesis in plants.
Which macromolecule is primarily responsible for storing genetic information?
Explanation: DNA stores genetic information in all living organisms. Proteins perform many functions, lipids store energy, and starch is a carbohydrate used by plants for energy storage.
What pigment gives plants their green color?
Explanation: Chlorophyll gives plants their green color by absorbing light for photosynthesis. Hemoglobin carries oxygen in blood, melanin colors skin and hair, and keratin is found in hair and nails.
Which blood component carries oxygen throughout the body?
Explanation: Red blood cells carry oxygen using hemoglobin. Platelets help in clotting, white blood cells fight infections, and plasma is the liquid part of blood.
What process do plants use to convert sunlight into food?
Explanation: Photosynthesis allows plants to make food from sunlight, water, and carbon dioxide. Respiration releases energy, osmosis moves water, and transpiration is water loss from leaves.
What is the basic unit of life in all organisms?
Explanation: The cell is the basic unit of all living things. Atoms make up molecules, tissues are groups of cells, and organs are made from tissues working together.
Which human organ is primarily responsible for filtering blood?
Explanation: Kidneys filter waste products from the blood. The heart pumps blood, the lungs handle gas exchange, and the liver processes nutrients and detoxifies substances.
What is the basic structural unit of the nervous system?
Explanation: A neuron is the primary cell that transmits nerve impulses. Axons are parts of neurons, muscle cells enable movement, and blood vessels transport blood.
Which organ is part of the human respiratory system?
Explanation: The lungs are essential respiratory organs exchanging oxygen and carbon dioxide. The liver digests and detoxifies, the stomach digests food, and kidneys filter blood.
What is the chemical symbol for water?
Explanation: H2O represents water, with two hydrogen and one oxygen atom. HO isn't correct, O2 is oxygen gas, and CO2 is carbon dioxide.
