Plant Tissues and Organs Flashcards
3 basic cell type of plant tissue
- Parenchyma
- Collenchyma
- Sclerenchyma
Most common plant cell type
Parenchyma cell
Parenchyma are found where?
cortex of roots, ground tissue in stems and mesophyll of leaves
Parenchyma function
- store starch, oils and water
What type of cell help heal wound to the plant?
Parenchyma cells
Have a thin flexible walls
Parenchyma cells
Plant cell that provide support to a growing plant
Collenchyma cells
Collenchyma cells have unevenly thick cell walls
True
Collenchyma cells are not strong and flexible
False
Collenchyma cells are found where?
under the epidermis, young stems, petioles, and leaf veins
The strongest plant cell type
Sclerenchyma cells
Sclerenchyma cells are found where?
Cortex of leaves and in stems
The second cell wall are hardened by what
Lignin
Sclerenchyma cells die when they reach maturity
True
What do humans make out of the sclerenchyma cells
Linen and rope
Plant organs are made out of three tissue systems
- Dermal Tissue
- Ground Tissue
- Vascular tissue
Tissue system that covers the outside of a plant
Dermal tissue
Dermal tissues forms the what of a plant?
Outer bark of trees
Dermal tissue function
- protects the plant
- secretes cuticle of leaves
Tissue system that is found inside a plant
Ground tissue
Where do ground tissues stores materials
in roots and stems
Ground tissue provides supports
True
Ground tissue is most commonly made of parenchyma cells
True
The tissue system that transports water, minerals and organic compounds.
Vascular tissue
Vascular tissue has one network of hollow tube
FALSE (two networks)
Two types of specialized tissue that compromises the vascular tissue
- Xylem
2. Phoem
Type of specialized tissue that transports water and minerals
Xylem
Type of specialized tissue that transports photosynthetic products
Phloem
A system that allows for the transport of water, minerals, and sugars.
Vascular system
Xylem contains 3 specialized cells which are?
- Vessel elements
- Tracheid cells
- Xylem cells
Type of xylem specialized cell that are long and narrow
Tracheid cells
Type of xylem specialized cell that dies at maturity
Xylem cells
Type of xylem specialized cell that are short and wide
Vessel elements
Cohesion-tension theory
Explains water movement
It is the tendency of water molecules to bond with each other.
Cohesion
