| Questão | Responda |
| Dermal Tissue | •Single OUTER layer of tightly packed epidermal cells – covers entire plant •Protects against water loss and pathogens *Cuticle & Periderm |
|
Vascular Tissue
Image:
Dermal (binary/octet-stream)
|
•INNER layer, Transports between roots & shoots Xylem cells – transport water up from roots Phloem cells – transports food from leaves to other parts |
| Ground Tissue | MIDDLE layer, particularly parenchyma, collenchyma, & sclerenchyma cells |
| Periderm | Protective, dermal tissues; replaces epidermis in woody plants |
|
Parenchyma cells
Image:
Rad (binary/octet-stream)
|
Most abundant; throughout plant Large, central space Perform most metabolism; synthesizes and stores organic products Ex. chloroplasts; fleshy tissue of fruit |
|
Collenchyma cells
Image:
Cel (binary/octet-stream)
|
Grouped in strands; supports young parts Thick, flexible; lack secondary cell walls Ex. “Strings” of a celery stalk |
|
Sclerenchyma cells
Image:
Nut (binary/octet-stream)
|
Fiber like cells; mechanical support for older, non growing parts of plants Rigid, thick secondary walls Ex. Hemp, flax, nut shells |
|
If stomata is CLOSED...
Image:
Stoma2 (binary/octet-stream)
|
•No H2O lost, BUT CO2 not available, so NO photosynthesis •Typically occurs when temps are HIGH, or at NIGHT when CO2 is HIGH from respiration |
|
If stomata is
OPEN...
Image:
Stoma1 (binary/octet-stream)
|
•CO2 can enter, BUT H2O is lost (transpiration), so risk of desiccation •Typically occurs during the DAY to provide enough CO2 for photosynthesis |
|
Monocots
Image:
Lil (binary/octet-stream)
|
•Single cotyledon (seed leaf) •Parallel leaf veins •Flowers = multiple of 3 Ex. Lilies, orchids, grasses |
|
Eudicots
Image:
Rose (binary/octet-stream)
|
•Two cotyledons (seed leaves) •Net leaf veins •Flowers= multiples of 4 or 5 Ex. Roses, peas, beans, oaks |
