2.6 The Plant Kingdom

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
