dermal tissue
protects, lets the plant retain or release water. Aids in absorbtion in roots.
vascular tissue
transortation system. Two types: Xylem and Phloem
ground tissue
Producing sugar, storing materials, and support.
meristematic tissue
ability to regenerate. Full of undiffientiated cells (Stem cells). CRitical in asexual reproduction.
cuticle
protective dermal layer, transparent (photosynthesis), keeps bacteria out
stomata
small pores on underside of leaf for gas exchange
guard cells
Modified epidermal cells. Responsible for opening and closing stomata.
palisade mesophyll
column shaped, tightly packed, contains chloroplast, location is ideal for photosynthesis
spongy mesophyll
Loosely arranged and creates an airy layer for gas exchange.
upper/lower epidermis
Outermost layer of dermis. Protection, secretes cuticle.
xylem
water, minerals, dead cells
phloem
vascular tissue, food, living cells
vascular bundle
vascular system (transport) for food/water
male reproductive parts
stamen: anther and filament
female reproductive parts
pistil: stigma, style, ovule, ovary
monocot
One cotyledon, parallel veins, random vasc bundles, fibrous roots, mult of 3
dicot
Two cotyledon, branch veins, ring vb, taproot, mult of 5
taproot vs fibrous root
Taproot is one main vein with other ones off of that one, and fibrous is more random and sprawled out
alternation of generation
sexual reproductive cycle of all plants
pollination vs. fertilization
Pollination is when pollen transfers, and fertilization is after pollination has sucessfully happened
transpiration
The process when plants take in water through the roots and it diffusing from the leaves. Light intensity, temperature increase, and wind speed can make transpiration increase. High humindy can make the process of transpiration slow.
photosynthesis
Light Reaction / Electron Transport Chain / Calvin Cycle
