Specialized Tissues in Plants 23-1
Transcript of Specialized Tissues in Plants 23-1
Seed Plant Structure
roots stems leaves
Plant Tissue Systems
- outermost layer of cells, 'skin'
- transport, 'bloodstream'
- the other tissues in between, 'stuffing'
Dermal, Vascular, and Ground Tissue
Dermal Tissue- layer of epidermal cells
- waxy layer
- protect leaf and give fuzzy appearance
root hair cells
- increase surface area and absorption
- regulate water loss and gas exchange
xylem- made up of
phloem- made up of
sieve tube elements
- thin cell walls, big vacuoles, chloroplasts
- make up supportive stalks of large plants
- thick, rigid cells; make ground tissue tough & strong
Plant Growth & Meristematic Tissue
meristems- tissue responsible for continuing growth
at the tips of roots and shoots
promotes cell division
apical meristem- produces length
reproductive plant organs are also produced in meristems
Classify each vegetable as a root, stem, leaf, bud, or other plant part.
How did you classify the onion? Why?
How did you classify the potato? How is its structure related to its function?
How did you classify the artichoke? What does its structure tell you about its function?
