“Stationary Animals that Eat Sunlight!!”

2. What is a plant?
Plants are multicellular Eukaryotes that have cell walls made of cellulose and carry out photosynthesis using green pigments called chlorophyll.

3. Overview of the Plant Kingdom
Four Main groups of Plants:
Mosses
Ferns
Gymnosperms - cone bearers
Angiosperms - flowering plants

4. Overview of the Plant Kingdom!!!

5. Overview of the Plant Kingdom
Four Main groups of Plants:

6. Have spores, not seeds - Have no roots
Mosses!!
Have spores, not seeds
- Have no roots

7. Also have spores not seeds Have roots
Ferns!!
Also have spores not seeds
Have roots

8. Are cone bearing plants like Pine trees Their seeds are naked!
Gymnosperms!
Are cone bearing plants like Pine trees
Their seeds are naked!

10. Angiosperms! Are flowering plants!!
Their seeds are surrounded by a fruit.
They make up 90% of all plants alive today

13. Plant Classification Plants Non-flowering Flowering 1 seed-leaf
2 seed-leaves
Spore-bearing
Naked seeds
Monocots
Dicots
Gymnosperms
No roots

Mosses
Ferns

14. Angiosperms! Monocots Dicots
Angiosperms are divided into 2 distinct groups named for their number of seed leaves:
Monocots
Dicots

15. Monocots vs. Dicots

20. Angiosperms! Stems can be:
Herbaceous – green and soft stemmed. Ex: dandelions
Woody – tough and strong stemmed. Ex: trees and roses

22. Angiosperms! Lifespan can be: Annuals – live ONLY one year
Biennials – live ONLY two years
Perennials – live many years

24. Plants have three main organs: Roots Stems Leaves
Plant Parts!!!
Plants have three main organs:
Roots
Stems
Leaves

25. Plant Parts!!! Plant Organ Function Roots Absorbs water and nutrients.
Anchors plant to the ground.
Stems
Supports the plant body.
Transports water and nutrients.
Leaves
Capture sunlight for photosynthesis
Gas exchange (stomata)

26. Plant Vascular (transport) Systems!
A plant’s vascular system (think veins) carries water and sugary sap all the way through the plant from roots to stem to leaves.

27. Plant Vascular (transport) Systems!
Two types:
1. Xylem – carries water from roots to rest of the plant
2. Phloem – carries sugars (called sap) from the leaves to the rest of the plant

29. Plant Roots! Two Main Types:
Fibrous Roots – fine, branching roots (Ex.: grasses)
Tap Roots – one large root (Ex: carrots!)

30. Tap vs. Fibrous Roots

31. I want you to be aware of: Rhizomes - a specialized underground stem.
Plant Stems!
I want you to be aware of:
Rhizomes - a specialized underground stem.

32. Rhizomes

33. Rhizome vs. Rhizoid

34. Stomata are opened and closed by guard cells that surround the stoma.
Plant Leaves!
Stomata (opening on underside of leaves for gas exchange) are found here.
Stomata are opened and closed by guard cells that surround the stoma.
Closing stomata prevents water loss and keeps the plant from drying out.

36. Plant Kingdom
Non-flowering Plants
Flowering Plants

37. Non - flowering Plants Do NOT produce flowers
. 3 groups
Non - flowering Plants
Mosses
Ferns
Gymnosperms
Do NOT produce flowers

38. Flowering Plants . 2 groups Monocotyledons Dicotyledons
. roots, stems, leaves
. vascular tissues (transport)
. flowers, fruits (contain seeds)
