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
Importance of Seed Plants
Paper
Furniture
Clothing
Food
Homework…
Create a T-chart to compare
angiosperms and gymnosperms
