3. b
4. d
5. a
Section B: Short Answer Questions (1 mark each)
1. Photosynthesis is the process by which green plants use sunlight to convert carbon dioxide and water into glucose (energy-rich sugar) and oxygen. It is important in the natural environment as it supplies oxygen for respiration and serves as the primary source of energy for all organisms.
2. The three main types of rocks are igneous, sedimentary, and metamorphic. Igneous rocks are formed from the cooling and solidification of molten lava or magma. Sedimentary rocks are formed from the accumulation of sediment or organic materials over time. Metamorphic rocks are formed when existing rocks undergo extreme heat and pressure, causing a change in their composition and structure.
3. A physical change involves a change in physical properties without altering the substance's chemical composition. For example, melting ice is a physical change. A chemical change, on the other hand, involves a reaction that leads to the formation of new substances with different properties. Combustion is an example of a chemical change.
4. Mitosis is the process by which a cell divides into two identical daughter cells. It consists of four main stages: prophase, metaphase, anaphase, and telophase. During prophase, the nuclear membrane dissolves, and the chromosomes become visible. In metaphase, the chromosomes line up along the center of the cell. In anaphase, the chromosomes separate and move to opposite poles. Finally, in telophase, the nuclear membrane reforms, and the cytoplasm divides. Mitosis is significant in cell division as it ensures the accurate distribution of genetic material.
5. The three states of matter are solid, liquid, and gas. In a solid, particles are tightly packed and have a fixed shape and volume. In a liquid, particles are loosely packed and can flow to take the shape of their container with a fixed volume. In a gas, particles are widely spaced and can freely move and spread, occupying the entire space available to them without a fixed shape or volume.
