We love our plants!
How Scientist Classify Plants
• They classify plants by asking really important question
Questions 1
• Does it have roots, a stem, and leaves?
Question # 2
• Does it have tube-like structures inside it to help transport water?
Q#3 Does it produce cones or flowers?Cones
Flowers
Groups of Plants
• Based on these three questions we can classify plants in four main groups
• Mosses• Hornworts• Liverworts• Ferns – which have
relatives that include conifers and flowering plants
Mosses
• No true roots • No true stems• No true leaves• Depend on direct
contact with water• Thrive in moist places
Hornworts
• No true roots • No true leaves • Depend on direct
contact with water• Live in moist places
Liverworts
• Similar characteristics as the other to but
• Can be found on rocks and trees
• Thrive in moderate or deep shade
Ferns
• Have a vascular system with roots to help anchor the plant securely to the soil
• Main root with smaller roots to obtain water and nutrients
How Plants Reproduce
• How do plants reproduce to ensure the species of the plant continues?
• Take 2 minutes and discuss with your group?
All Living Things Reproduce
• Plants reproduce • 3 ways• With Spores• Seeds from cones • Seeds from flowers
With Spores
• Ferns, moss and hornworts reproduce with spores
• They look like soft fluff are scattered by the wind fall to the ground and sprout
Cones
• Conifers produce cones• Seeds are inside these
cones and when the cone opens the seeds are scattered by the wind and animals
Flowering Plants
• Flowering plants produce seeds in a flower or a fruit
• These plants include trees, shrubs, vines and flowers. Fruits and vegetables as well
