Plant Tissues Flashcards
(18 cards)
What is the function of vascular tissue?
○ Long distance transport
○ Provides structure & support (secondary function … result of protecting this special type)
What is the overall function of xylem tissue?
Water & minerals
ROOTS to SHOOTS!
What are the 4 cell types that compose xylem tissue?
- Xylem parenchyma
- Xylem fibers
- Tracheids
- Vessel elements
Tracheids and Vessel elements are classified as what type of cells?
Conducting cells
Describe Tracheids.
long, narrow, tapered ends
Location=Xylem
Describe Vessel Elements.
Wider, Stacked, Open end walls
Location=Xylem
What is the overall function of phloem tissue?
Carbohydrate transport via multi-directional movement
What 4 cell types compose phloem tissue?
- Phloem parenchyma cells
- Phloem fibers
- Sieve tube elements
- Companion cells
Describe sieve tube elements.
– Conducting
– Alive (barely)
– No nuclei, mitochondria, ribosome
Location=Phloem
What is the function and location of the companion cells of phloem tissue?
-Adjacent to each sieve-tube element and Helps it.
-Alive!
Location=Phloem
What are the two types of meristem?
> Primary Meristem
>Secondary Meristem
Describe 1° meristem: Purpose? Location? Type of growth? Type of plants?
§ All plants
§ Increase of Length
§ 1*growth = herbaceous (dermal, ground, and vascular)
§ Located at growing tips (apical)
Describe 2° meristem: Purpose? Location? Type of growth? Type of plants?
§ Lateral meristems
§ Increase of width
§ Some plants (not all)
§ Woody growth is produced – woody 2* growth
In meristem, where is the zone of cell division located?
@ the core of the meristem
What composes the zone of cell elongation?
- protoderm
- ground meristem
- Pro cambium
In the zone of cell differentiation, what does the protoderm turn into?
Trichome…. guard cell…
In the zone of cell differentiation, what does the ground meristem turn into?
Ground tissue
In the zone of cell differentiation, what does the pro cambium turn into?
Xylem or Phloem
