1 “Stationary Animals that Eat Sunlight!!”
Plants!!! “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!

9

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 with 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

21

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

23

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

28

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.

35 Stomata/Guard Cells

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)

39 Plant Classification Plants Non-flowering Flowering 1 seed-leaf
2 seed-leaves Spore-bearing Naked seeds Monocots Dicots Gymnosperms No roots with roots Mosses Ferns
