Review Which layer of the leaf contains the cuticle? Which layer of the leaf has the most chloroplasts in its cells? Which layer of the leaf contains vascular tissue? What are stomata? How do stomata open and close?

Review What is the purpose of stems? What purposes do roots serve?

Vascular Tissue/ Angiosperms & Gymnosperms Study Pack #6

Today’s Goals… I can describe the different types of vascular tissue. I can distinguish between angiosperms and gymnosperms.

Vascular Tissue Vascular system -Tube-like structures that carry water, nutrients, and other substances through the plant Three tissues make the vascular system in a seed plant Xylem Phloem Cambium

Vascular Tissue Xylem tissue Made up of hollow, tubular cells that are stacked one on top of the other to form a vessel Transport water and dissolved substances through the plant Thick walls of xylem provide support Runs from roots to leaves

Vascular Tissue Phloem tissue Made of cells that are stacked to form tubes Move food from where it is made to other parts of the plant where it is used or stored Runs from leaves to roots

Vascular Tissue Cambium Between xylem and phloem Produces xylem and phloem cells These new cells make the stems and roots thicker

Gymnosperms Vascular plants that produce seeds not protected by fruit Do not have flowers Leaves are needlike or scalelike Evergreens Examples – pines, firs, spruces, redwoods

Angiosperms Has flowers and produces fruits with one or more seeds Example: peaches
