Which group do I belong to?
Boys vs. Girls.One boy and one girl will go head to head in the ‘Which group do I belong?’ to game show!
I will read out a number of clues; when you think you know which group the animal (vertebrate) belongs to, you must call out your buzzer noise!
Girls – bang!Boys – pop!
Then the whole class will be asked a question.Then, we start again with a different boy and girl.

Mosses: They have simple leaves and shallow roots, with no proper vascular systems. The leaves are very small and are not covered with a waterproof, waxy cuticle layer. Mosses, Angiosperm and Lichen are often found in damp areas as they dry out easily. They reproduce using spores.
Ferns: They have proper roots and stems, and leaf-like fronds. The leaves are not covered in a waterproof, waxy cuticle layer and so they dry out easily and are generally found in damp places. They do have a vascular system. They reproduce using spores.
Conifers: They have vascular tissues. They are large plants with proper roots and stems and needle-shaped leaves with a waxy cuticle. They are good at surviving in dry or cold climates. They reproduce using seeds found in cones.
Flowering Plants: They have vascular tissues. They have proper roots and stems and have flowers. Their leaves are large and flat and have a waxy cuticle. They reproduce using seeds found in fruits.
