Universal is more precise
Uses litmus paper/Universal indicator
Igneous, sedimentary, and metamorphic
Igneous are hardest, sedimentary are softer,
Day and night: caused by rotation of axis

Orbit and rotate are better terninologies
Most remember planets
Movement, Respiraiton, Sensitivity, Growth, Reproduction, Excretion and Nutrition = MRSGRENS
Cells make tissue, tissue makes organs, orgarns make organ system, organ system make organisms,.
Food Chains
Plant cells have cell wall, chloroplast and vacuole, while animals don't have it. Chloroplast are used to make photosynthesis.
Unicellular and multicellular. Uni: one cell organisms. Multi: many cell organism.
Eukaryotic = cell with nucleus
Prokaryotic = cell without nucleus
Cells with a unique purpose are called specialised cells.
Subatomic Particles
Protons, electrons and neutrons
A group of cells make up a tissue, many tissue makes an organ, multiple organs make an organ system, and multiple organ systems make an organism.
