Requirements Land plants need to …
Requirements Land plants need to … • Provide support (so they don’t collapse)
Requirements Land plants need to … • Provide support • Obtain water + minerals
Requirements Land plants need to … • Provide support • Obtain water + minerals • Transport materials (food, water + minerals)
Requirements Land plants need to … • Provide support • Obtain water + minerals • Transport materials • Prevent water loss
Requirements Land plants need to … • Provide support • Obtain water + minerals • Transport materials • Prevent water loss • Get sperm & egg together!
Kinds of Land Plants 1. Non-vascular (primitive)
Kinds of Land Plants Non-vascular (primitive) • Simple structures
Kinds of Land Plants Non-vascular (primitive) • Simple structures • Must live in moist areas
Kinds of Land Plants Non-vascular (primitive) • Simple structures • Must live in moist areas • Absorb water through all body parts
Kinds of Land Plants Non-vascular (primitive) Ex. Mosses, liverworts, hornworts
Kinds of Land Plants Non-vascular (primitive) Ex. Mosses, liverworts, hornworts Human uses: used for fuel (burning) & diapers (primitive cultures)
Kinds of Land Plants 2. Vascular
Kinds of Land Plants 2. Vascular - land plant with vascular tissue
Kinds of Land Plants 2. Vascular - land plant with vascular tissue Vascular tissue – a system of tiny tubes
2 Kinds of Vascular Tissue Phloem -
2 Kinds of Vascular Tissue Phloem – transports food - movement is up & down
2 Kinds of Vascular Tissue Xylem -
2 Kinds of Vascular Tissue Xylem – transports water & minerals
2 Kinds of Vascular Tissue Xylem – transports water & minerals • Movement only upwards
2 Kinds of Vascular Tissue Xylem – transports water & minerals • Movement only upwards • Thick cell walls
Vascular Plants Vascular Plants have roots, stems, and leaves
Roots • Anchor plant in ground
Roots • Anchor plant in ground • Absorb water & minerals from soil
Roots • Anchor plant in ground • Absorb water & minerals from soil • Store materials (food) for plant for later use
Roots 2 Types of roots:
Roots 2 Types of roots: 1. Fibrous (tangled mass) (ex. grass)
Roots 2 Types of roots: 2. Tap (deep & penetrating) (ex. carrots)
Stems - Provide support
Stems • Provide support • Transport materials (between roots & leaves)
Stems 2 Kinds of stems: 1. Herbaceous (green & soft) (Ex. dandelions)
Stems 2 Kinds of stems: 2. Woody (hard & rigid) - made of layers of xylem (ex. trees & shrubs)
Stems Outer bark (hard & protective) Typical structure: Phloem Vascular cambium (new growth area) Layers of xylem (growth rings) Pith (soft core)
Leaves - Produce food through photosynthesis
Leaves Typical Structure:
Leaves Photosynthesis:
Types of leaves Needle-shaped (ex. Pine, spruce, hemlock, larch)
Types of leaves Simple (one main stem; blade in one piece) (ex. Oak, maple, apple, cherry)
Types of leaves Compound (leaf blade contains many stems; blade in several pieces) (ex. Locust, hickory, ash, walnut)
