Germination Seed grows into new plant NEEDS Water Oxygen Warmth (correct temp)
Experiment to show conditions needed for germination
Gamete A sex cell Sperm or egg Fuse to form a zygote
Geotropism How a plant grows in response to gravity (growth response of a plant to gravity) Roots – grow down no matter how seed is planted Shoots always grow up
Genetics Study of inherited characteristics / traits
Geothermal Energy Heat energy from under the surface of the Earth
Group Vertical column on Periodic table Group number = number of electrons in outside shell All elements in group have similar properties
Groups Group One = Alkali Metals Group Two = alkaline earth metals Group Seven = halogens Group Eight (Zero) = Noble Gases
Group One Alkali Metals (Li, Na, K) One electron in outer shell – valency =one Form positive ions – give electron away Highly reactive – water Stored under oil
Group 8 Halogens Seven electrons in outer shell Valency = one Cl 2 and F ions in water treatment Group 7 Noble Gases Eight electrons in outer shell Valency = zero STABLE Unreactive (role model for all the others – they “want” to be like nearest Noble gas)
