Biology Ch. 6.2

Kingdom Plantae

Mosses and Relatives Have no roots. Instead have small root-like structures called rhizoids. Grow in mats of low, tangled vegetation that can hold water like a sponge.
Bryophytes Common in moist, shady areas. Sphnagum moss is valuable as it is highly water absorbent and nutrient rich (peat moss).
Ferns and Relatives Have vascular tissue. Grow taller and live in a wider range of habitats compared to mosses. Whisk fern, club mosses, horsetails.
Cone-bearing Plants They have roots, stems and leaves. They have seeds exposed on the surface of cones.
Angiosperms Grow and develop seeds that are enclosed within a fruit. Trees, shrubs, grasses, etc.
Pistil Female reproductive organ.
Pollination Adaptation Most methods involve birds, insects, bats, etc. Colour, shape and scent of the flower helps the pollinator recognise the source of food.
Self-Pollination Produces genetically identical offspring.
Seed Structure The hard case of the seed allows the embryo inside to survive adverse conditions such as dry & hot conditions.
