Primary General Studies: Classifying Plants and Animals and Biodiversity (Paper 1 (basics))

Paper one builds the basics: the two large groups of plants and animals, vertebrates and invertebrates, six legs on insects, gills in fish, bird and mammal features, and flowering versus non-flowering plants.

Direct answers　Link each group with one clear feature and one example so groups do not get mixed up.

03　Answers and one-line notes

#	Answer	One-line note
1	Plants and animals.	Plants make their own food while animals eat other living things, so these two groups come first.
2	Six legs.	Six legs is the fixed feature of insects; spiders have eight and are not insects.
3	Gills.	Gills take oxygen from water, so a fish runs out of oxygen out of water.
4	60 per cent.	15 divided by 25 times one hundred gives 60 per cent.
5	10 kinds.	25 minus 15 is 10.
6	For example fish, amphibians and reptiles.	The other two are birds and mammals; all five share a backbone.
7	Feathers and a beak.	Feathers keep birds warm and the beak replaces teeth for feeding.
8	Hair on the body, giving birth to live young, and feeding young with milk.	All three appear together in mammals, including whales that live in water.
9	Ferns and mosses do not flower and reproduce by spores.	Non-flowering plants have no flowers or fruits and spread by spores, so they grow in damp places.
10	A spider has eight legs and an insect has six, so a spider belongs with the arachnids.	Counting the legs is the quickest way to tell them apart.

04　What to do after marking

After marking, redo only the wrong items and write down which step went wrong (formula, unit, or misread number).
Repeat the same item two days later; move to the next paper only when both attempts are correct.
Parents only need the answer and note columns; there is no need to explain every item.

After paper one, take paper two and sort out series against parallel in one pass.Tutor Registration →
