Transcript Structure of Seed Plants

Structure of Seed
Plants
Vascular Tissues
What is a Vascular Tissue?
Specialized tissues that conduct nutrients
and water from one part of the plant to
another.

2 Types of Vascular Tissues
1) Xylem
2) Phloem
Xylem

Xylem type of tissue that provides support and
conducts water and nutrients from the roots.
Phloem

Phloem The tissue that conducts food in vascular
plants.
The Roots!
Root Functions
1) Supply plants with water and minerals.

2) Hold plants securely in soil.
3) Help store surplus food in some plants.
Ex: Carrots, potatoes, onions.
Root Structure
Root cap release a substance that helps the root grow
through soil.
Root Systems
2 type of root systems
1) Taproot, one main root that grows downward.

2) Fibrous, several roots that spread out from the
base of a plant’s stem.
What type of roots do these plants
have?
Stem (Shoot)
Stem Functions
1) Stems support the plant’s body (flowers/leaves).

2) Stems support materials (via xylem and phloem)
between the roots and leaves.
3) Some stems store water/materials
Ex: Cactus have adapted to store water in their
stems.
2 Types of Stems
Herbacious
Stems that are soft,
thin, and flexible.
Woody
Rigid stems made of
wood and bark.
Leaves

The main function
of leaves is to make
food for the plant.
1.
Chloroplast in leaves
capture sunlight.
Leaves absorb CO2
