Tissues Flashcards
what is the function of apical meristems
increase length of plant and making new cells
what is the location of apical meristems
at the tip of stems, roots and axillary buds
protoderm produces
dermal tissue
ground meristem produces
ground tissues
provascular produces
vascular or transport tissues
what is the function of lateral meristems
increase diameter of stem/root and produce secondary tissues
what is the location of lateral meristems
sides or in between two types of tissues
vascular cambian produces
secondary vascular tissue
cork cambian produces
periderm
what is the function of intercalary mersistem
increase plant in length continuous (blades of grass)
what is the location of intercalary meristem
nodes
what are parenchyma cells
cells with an evenly thin primary wall
aerenchyma
air space
chlorenchyma
chloroplasts
storage parenchyma
food
what separates ground tissue from transport tissue
endodermis
collenchyma cells have an
unevenly thick primary wall
sclerenchyma have secondary walls that are
thick
the gridiness of pears is due to the
sclerids
what is the function of schlerenchyma
to protect the softer tissue and makes the seed hard
what type of tissue is xylem
vascular tissue
what is the function of xylem
transport water
what are the two types of xylem cells that are involved with water transport
tracheid and vessels
what do ray cells do?
transport material from side to side
all plants have ____ but not all have ____
tracheids , vessels
tracheids have end ___ and are long and ____
walls, thin
vessels either are ____ opened or have ______
fully, perforated plates
what is the downside to vessels
cavitation
what is cavitation
when the water column is broken due to tension from water being pulled
cavitation results in a ___ (bubble)
embolism
what prevents air bubbles from entering into adjacent cells
pits
what tissue system does phloem belong to
vascular
what is the function of phloem
transport photosynthates, food, dissolved carbs
what are transporting cells
sieve tube
companion cells
support
what cells are outside or move material side to side
parenchyma
what tissue system is the epidermis a part of
dermal
what is the function of the epidermis
prevent drying out
the epidermis is usually ___ cell thick
one
pavement cells
plain
guard cells
stomata
