Flashcards in 10/20 Plant Anatomy Deck (63):
plants organized in what?
root is the same as what in a human?
tissue is the same as what in a human?
composed of several types of tissues that carry out a particular function.
composed of a group of cells with a common function and structure
what are the three basic plant organs?
roots, stems and leaves
shoot system needs....
water and minerals
root system needs....
photosynthetic products from shoot sys
have one cotyledon
have two cotyledon
what are the 3 types of tissues?
dermal, vascular and ground
dermal tissue fx?
protects against dehydration, insects, animals, and pathogens
one single layer
waxy coating on leaves and stems
fx of cuticle
prevent dehydration and pathogens
tiny openings on leafs that allows plants to breathe
vascular tissue transport materials between what?
leafs and roots (photosynthetic products)
transports water and dissolves minerals
transport organic nutrients (sugars)
made up of cellulose
filled up with water (firmness) makes up cell rigid
have vascular tissue in the center (pith)
have vascular tissue in the edges "ring" (cortex)
plant cells have 3 unique parts
chloroplast, the sites of photosynthesis, central vacuole
alive(Y), 1cellwall(Y), 2cellwall(N), fx photosynthesis, storage, metabolic process
alive(Y), 1CW(Y), 2CW(N), fx flexible support, elongate, "string of celery"
alive(N), 1CW(Y), 2CW(Y), fx support
secondary cell wall location
primary cell wall
xylem (water conducting cells)
alive(N), 1CW(Y), 2CW(Y), fx support and water transport (diff, xylem wider and tracheids thinner opening)
tracheids (water conducting cells)
alive(N), 1CW(Y), 2CW(Y), fx support water tansport (similarities openings for water transport)
sieve tube members (sugar conducting cell)
alive(Y), 1CW(Y), 2CW(N), fx transport sugar
companion cell (sugar conducting cell)
alive(Y), 1CW(Y), 2CW(N), fx transport and production of proteins
carrot, radishes, potato
does not have a endodermis
cactus spine and not leafs
too much sun, too much surface area, less water loss
anchors plant in the soil, absorb&transport minerals and water, stores food
thin roots spread out shallowly in the soil
have one main vertical taproot with many small secondary lateral roots growing outward
is an extension of an epidermal cell
ex of prop roots
ex aerial roots
ex of climbing roots
ex of aquatic roots
ex sucker root
ex food storage root
why would farmers harvest carrots, beets or sweet potatoes befor plant's flower (veggie)
make the flower sweeter
support the leaves and flowers
green stem fx
what are buds?
stolons or runners
grow horizontal along the ground surface, reproduce asexually
store food and have buds, they spread and form new plants
peeling onion is removing what?
leaves attached to a short stem
photosynthesis, composed of lamina (blade) and petiole (stalk)
types of leaves
simple leaf, and compound leaf
one blade per leaf, has bud by stem
many distinct blade per leaf, no bud but has bud wher the rachins meet the stem (branch)
epidermis covered by waxy coat?
cuticle and prevents water loss but also prevents gas exchange
leaves covered with hairs, fx catch water, reduce airflow and produce wax
tightly packed cells on the upper surface
