Chp.29 Plant Cell Types Flashcards
What are the 3 plant cell types?
Parenchyma
Sclerenchyma
Collenchyma
Describe Parenchyma
Typical photosynthetic cell
Thin c/w
Describe Collenchyma
Thicker cell wall than parenchyma young plant (seedling)
Describe Sclerenchyma
Thickest c/w
lignin in the cell wall
Dominate when major growth has stopped
What is the significance of collenchyma’s thicker cell wall (thicker than parenchyma)?
provides more support
What is the significance of sclerenchyma’s very thick c/w (the thickest c/w)?
Provides the most support for the plant
What are the major tissue systems of plants?
Dermal Tissue
Vascular Tissue
Ground Tissue
Meristem Tissue
What do vascular tissue systems do and examples?
Transport Fluids
Ex. xylem and phloem
What cells make up vascular tissue?
Parenchyma
Sclerenchyma
What does dermal tissue do?
forms outer coverings of plants
What cells make up dermal tissue?
Parenchyma
What does ground tissue do?
Form roots, stems and leaves
What cells make up ground tissue? (remember the different parts of this type of tissue)
Roots= Collenchyma and Sclerenchyma
Stems and leaves= parenchyma
What does meristem tissue do?
It is where there is the fastest growth
Where is the fastest growth in plants?
Meristem tissue
