• All plants are EUKARYOTIC which means they all have a nucleus and MEMBRANE -BOUND organelles.
• All plants make their own food; therefore, they are considered photosynthetic AUTOTROPHS.
3
All plants are made up of many cells and are called MULTICELLULAR.Plants all have a cell wall made of CELLULOSE.

THE PLANT KINGDOM
8
Plants are grouped by:
1. The presence or absence of vascular tissue. Vascular tissues are specialized cells that transport water and other materials. Found in almost all land plants. Allows materials to be distributed more efficiently.
2. Their method of reproduction.
9
Types of Plants:Seedless Nonvascular Plants
• NONVASCULAR PLANTS – do not have a vascular system or internal network for transporting water and nutrients within their body.
• ALL nonvascular plants lack true roots, stems and leaves.
• A group of nonvascular plants is Bryophytes, which includes mosses, liverworts and hornworts.
11
Types of Plants:Key Features of Seedless
Nonvascular Plants
1. Small size – water and nutrients must enter by osmosis or diffusion (because they lack roots).
2. Require water for sexual reproduction – to allow sperm to swim to other plants and fertilize their eggs.
12
13
Types of Plants:Key Features of Vascular Plants
1. Have VASCULAR TISSUE for transporting nutrients.
2. Larger and more complex than nonvascular plants.
3. Not dependent on being close to water.
14
Seedless Vascular Plants
• Seedless vascular plants include club mosses, horsetails and ferns. The most numerous phylum of these is the fern. Ferns and their relatives have true roots, stems and leaves.
• This group of plants was the first to conduct water, so they have specialized cells for conducting water called tracheids.

Two types of Vascular Tissue1. XYLEM – transports water from the roots
to all parts of the plant, (only flows up). Made of dead material.
2. PHLOEM – transports food / nutrients down from the leaves. Made of living material.

Seedless Vascular Plants:Ferns
• Do not have seeds, have spores, found on the underside of the leaf.
• Leaves are called fronds.• 1ST appeared 400 million
years ago.• Has both male and
female reproductive structures.
• The scientific division for Ferns is Pteridophyta.

Types of Vascular Plants: Seed = Gymnosperm
• Plants whose seeds do not develop within a sealed container (fruit).
• Means “naked seed”• Sperm is carried by the
wind.• Ex. Pine trees, cycads,
conifers, palm trees.

Types of Vascular Plants: Seed = Angiosperms
• FLOWERING PLANTS• MOST SUCCESSFUL PLANT GROUP• Seeds are enclosed within a fruit or flower.
Flowers aid in attracting pollinators.Fruit protects developing seeds and
allows seeds to be dispersed at greater distances (when eaten by animals)
Seeds have a supply of stored food called the endosperm.

Types of Vascular Plants: Seed = Angiosperms
31
Types of Angiosperms:
32
Monocots vs. Dicots
Seed 1 cotyledon 2 cotyledons
Flower Parts
Multiples of three Multiples of 4 or 5
Leaves Parallel Veins Netted Veins
Roots Fibrous Tap
Vascular bundles
Scattered Arranged in a rings
