General Biology 1 (Part II) Flashcards
3 parts of the Plant Tissue
Vascular Tissue
Ground Tissue
Dermal Tissue
A waxy layer that protects against ultraviolet light damage and water loss.
Cuticle
Epidermal outgrowth that can be unicellular or multicellular.
Trichomes (Hairs)
Pores that control the exchange of gases and water transpiration in plants.
Stomata (Stoma)
3 types of Ground Tissue
Parenchyma Tissue
Collenchyma Tissue
Sclerenchyma Tissue
Give the 3 Characteristics of Parenchyma Tissue
Thin cell- wall
Have intercellular spaces
Oval in shape
Parenchyma’s Locations :
Leaves
Stem
Root
3 functions of Parenchyma Tissue
•Storage
•Secretion
•Transport Photosynthesis
3 Characteristics of Collenchyma Tissue
Thick cell wall
long cell
Have intracellular Space
Collenchyma’s Locations :
Usually found in stems
Leaves
Collenchyma’s Function?
Provide structural support of the plant.
What Tissue in Plants is this?
Long and narrow cells?
Sclerenchyma Tissue
What Tissue in Plants is this?
Very Thick walls - lingin
Sclerenchyma Tissue
What Tissue in Plants is this?
Dead; cell organelles are absent
Sclerenchyma Tissue
There are 4 types of Sclerechyma’s Location
Trunk
stems
veins of leaves
nuts
What tissue is that “ Provide a lot of strength to the plant” ?
Sclerenchyma Tissue
Two types of Vascular Tissues in plants :
Xylem and Phloem
Xylem or Phloem :
One- way flow
Xylem
Xylem or Phloem :
Two- way flow
Phloem
Xylem or Phloem :
Water and minerals
Xylem
Xylem or Phloem :
Water and food
Phloem
Xylem or Phloem :
No end walls between cells
Xylem
Xylem or Phloem :
End walls with perferations
Phloem
Xylem or Phloem :
Stiffened with lignin
Xylem
Xylem or Phloem :
Photosynthesis Products
Phloem
Xylem - _____________
Transpiration
_________ in plants :
Plant’s primary water- conducting tissue
Xylem
