Animal cell — key features?
Nucleus, cytoplasm, membrane, mitochondria.
Plant cell — extra structures?
Cell wall, chloroplasts, vacuole.
Mitochondria — role?
Releases energy during respiration.
Cell respiration — equation?
Glucose + oxygen → CO2 + water + energy.
Photosynthesis — equation?
CO2 + water + light + chlorophyll → glucose + O2.
States of matter — particle movement?
Increases with heat, solids fixed shape, gases no fixed shape or volume.
Solid — shape and volume?
Fixed shape and volume.
pH indicator — purpose?
Changes colour based on solution's pH.
Elements vs compounds?
Elements are one atom type; compounds are chemically bonded elements.
Mixtures — bonding?
Components are not chemically bonded.
Speed formula?
Speed = distance ÷ time.
Energy transfer — principle?
Energy moves but is not created or destroyed.
