Transcript of Bryophytes, Conifers and Ferns

12,000 species
Come in all sizes
Moss patches can make it's own soil from particles in the environment
Grow close together in damp or shady locations
Can grow in temperatures just above 0 degrees
Cannot survive in polluted environments
Do not have flowers or seeds
About 23,000 species
Can survive in almost any temperature but specific depending on species
All require moisture- swamps, soil, dung, antlers of deer and moose
Not large
Include mosses and liverworts
Not flowering plants
Live in damp places
Have small leaves or leaf-like structures without roots
Have chlorophyl for food making
8,000 species
Very similar to mosses
Typically grows around copper mines in damp acidic soil, on walls, rocks and mine-spoil
Reproduce sexually and asexually
• Have pine cones
• Produces its seeds within a cone and needles instead of leaves
• Survive cold, dry winters with extremely cold temperatures, conditions can be wet, hot and humid
• Are trees with needle-like leaves that make their seeds not in flowers but in cones

The world’s tallest tree, the redwood is a conifer
• Many conifers are cone shaped, which helps them she snow from their branches in winter
• The needle-like shape and waxy coating of the leaves helps the conifer to save water
• Originated from Australia
• Grow in places where there is plenty of water
• Eventually some ferns were able to figure out how to live in dry places
• stem is usually entirely below the ground and takes the form of a rhizome
• Have roots
• Collect sunlight for photosynthesis
• leaves have a waxy layer
• can live in drier conditions than mosses although ferns prefer a damp, shady environment
