Sclerenchyma
Sort the features of the various kinds of ground tissue to their correct category.
Living at maturity (1)
Living at maturity (2)
Dead at maturity
Unevenly thickened, nonlignified primary wall
Usually found in the periphery
Supports young and growing organs
Commonly occurs in strands or cylinders
Usually elongated
Commonly found under epidermis in leaves/petioles & around eudicot leaf veins
Thick, often lignified secondary cell wall
Srengthens and support plant parts that are elongating
Made of fibers and sclereids
Often metabolically active, Photosynthesis, Storage, Secretion, Regeneration
Typically only posses a primary cell wall
Has chlorenchyma, glandular, and transfer cells
Makes up the cortex and pith
Makes up the mesophyll
Organize the features of the cells that form Sclerenchymal tissue.
Short
"Cuboidal"
Inflexible & ridgid
Can form hard, impenetrable surfaces
Ex: shells of nuts & fruit pits
Long
Flexible
Found where strength and stability are important
Ex: Wood
Organize these options into the right categories
•Compactly arranged and exterior is covered in cuticle
•Function in protection and preventing water loss
cutcile
guard cells
trichomes
cork
cork cambium
Phelloderm
Lenticels
Organize the features of the epidermis.
Waterproof layer
Coats aerial cells
Consists of wax and cutin
Minimizes water loss (1)
Covers cells in either a smooth sheet, rods, or filaments that extend upward
Prevents gas exchange
Allows for gas exchange within the cuticle
Guard cells
Stromato pore
Hairs
Protective roles
Deters herbivores from eating the plant
Protects from overexposure to sunlight
Minimizes water loss (2)
Absorptive roles
Root hairs
Epiphytic plants
Which of the following are features of guard cells?
Cells swell by absorbing water, allowing the pores to open
They exist in pairs making up a single stomata
Help prevent water loss
Helps prevent getting eaten by herbivores
Plays protective and absorbative roles
