Biomes and Plants
In this lab we will look at plants and adaptations they have made to live in particular biomes.
Points to consider:
- An environment is defined by abiotic and biotic factors. Abiotic factors include temperature, light, water and nutrients. Biotic factors are other organisms in the environment.
- Soils are a product of the environment in which they are forming. The climate of an area favors formation of particular soils.
- Biomes are defined as extensive communities classified by the predominant vegetation type and characterized by the adaptations of organisms to their environment.
- Plants in a biome adapt to the abiotic and biotic factors found there.
Plants are multicellular eukaryotes that are photosynthetic autotrophs.
Summary of the Plant Kingdom
After Wallace, Sanders and Ferl. Biology - the Science of Life. 4th edition. Table 25.1
|Non-vascular Plants (bryophytes)||liverworts, mosses||Little or no supporting or vascular tissue|
|Seedless Vascular Plants||horsetail, club moss, ferns||· A root system that absorbs water and nutrients
· A shoot system of above ground photosynthetic parts, stems and leaves, covered in a waxy cuticle to reduce water loss.
· Specialized tissues which conduct water and nutrients through the roots, stems and leaves.
|Seeded Vascular Plants||· Gymnosperms
|· Cone bearing plants (naked seeds)
· Flowering plants
