Vascular Tissue
• Type of plant tissue specialized to conduct water and nutrients throughout a plant.
![Page 3: Biology 22 3[1]](https://reader033.fdocuments.net/reader033/viewer/2022061119/546a6de7af7959842c8b64c7/html5/thumbnails/3.jpg)
Tracheid
• Hollow plant cell in xylem tissue with thick cell walls that resist pressure.

Xylem
• Vascular tissue that carries water upward from the roots to every part of a plant.

Phloem
• Vascular tissue responsible for the transport of nutrients and the carbohydrates produced by photosynthesis.

Lignin
• Substance in vascular plants that makes cell walls rigid.

Root
• Underground organ in plants that absorbs water and minerals.

Leaf
• Photosynthetic organ that contains one or more bundles of vascular tissue

Vein
• In plants, a cluster of vascular tissue in leaves; in animals, a blood vessel that returns blood to the heart

Stem
• Supporting structure that connects roots and leaves and carries water and nutrients between them

Rhizome
• Creeping or underground stem in ferns

Frond
• Large leaf of a fern

Sporangium
• Structure in ferns and some fungi that contains spores
![Page 14: Biology 22 3[1]](https://reader033.fdocuments.net/reader033/viewer/2022061119/546a6de7af7959842c8b64c7/html5/thumbnails/14.jpg)
Sorus
• Cluster of sporangia on the underside of a fern frond
![Page 15: Biology 22 3[1]](https://reader033.fdocuments.net/reader033/viewer/2022061119/546a6de7af7959842c8b64c7/html5/thumbnails/15.jpg)
Key Concept
• Both forms of vascular tissue—xylem and phloem—can move fluids through the plant body, even against the force of gravity.

Key Concept
• Seedless vascular plants include club mosses, horsetails, and ferns.

Key Concept
• Ferns and other vascular plants have a life cycle in which the diploid sporophyte is the dominant stage.
