34 Cards in this Set

  • Front
  • Back
flowering plants
oak trees, rose bushes
nonflowering plants
moss, algae
2 types of higher plants
gymnosperms and angiosperms
gymnosperm
higher plant

"naked", have uncovered seeds

ex pine tree, Xmas tree
angiosperm
higher plant

covered seeds

ex: peaches, apples

2 kinds:
monocotyledon
dicotyledon
2 kinds of angiosperm: monocotyledon
one seed leaf or cotyledon

ex: cornseed

1 single vein //
1 coty embryo
scattered stem, vascular bundles of water

fibrous roots, not 1 root
flowers in multiples of 3
2 kinds of angiosperm: dicotyledon
2 seed leaves or cotyledons

ex: peanut, bean, can't break in 1/2

netlike veins
2 coty embryos
ring for stem
tap root: carrots
flowers multiples of 4/5
fiber cells
don't move food --> rigidity
phloum
vascular plants

transports sugars/others to roots

cell has dividng nucleus X 2, --> 2 new cells, transports food

big --> ploum condcuting cell
--- not alive, but some features can move food

small --> companion cell, has nucleus
xylum cells
moves H20 and minerals

when mature, cell wall broken down and just cytoplasm

lots of these cells = HOLLOW TUBE moves H20

moves by cohesion and adhesion,

NO PUMPS IN PLANTS!

pits - H20 leak out horizontally

transport water:
vessels - larger, perforated end walls

tracheids - conductive and supporting cell, <er, pitted (not perforated) walls
sieve tube
moves organic material to roots

transports food material, usually in flowering plants
sieve plates
holes in the cell wall
node
where find bud
internode
d. b/t 2 nodes, not standarad
vegetative branch
own plant
leaf
find bud, everything above = leaf
simple leaf
blade, petiole (stalk of leaf), auxiliary bud
compound leaf
leaflet, auxillary bud
stoma
small hole on top layer of plant

releases gas

regulated by osmosis
types of plant tissue: meristematic
happy b/c having 'sex'

apical and lateral
types of plant tissue
meristematic
surface
fundamental
vascular
types of plant tissue: surface
exterior

epidermal - stem, root, leaf, etc, living cell layer thick

cutin - waxy part of leaf

root hairs - longer extension of epidermal cells on root, WATER ABSORP

stomatal appartaus - hole/pore in root/stem

triochomes - hairs, extensions of epidermal

bark - trees
suberin - prevents water getting in, found in cell walls, cork
types of plant tissue: fundamental
tissue makes up plants, 3 cell types

parenchyma - basic living plant cells, how others derived, no 2ndary walls

collenchyma - parenc w/ wall thicks in corners, more rigid a little

sclerenchyma - MOST RIGID ex: wood
types of plant tissue: vascular
tissues transport food and H20

phloem - food moving tissue

xylem - H20 moving tissue
meristematic types
apical - cell divison on TOP of plant, plant grows vertically

lateral - --> plants >er in diameter
meristematic: apical
cell divison on TOP of plant, plant grows vertically

shoot - caueses plant to grow upwards

root - grow down into soil
meristematic: lateral
plants >er in diameter

vascular cambium - -->es vascular tissue (wood and phloem)

cork cambium -->es cork (not living, floats in H20 b/c suberin)
cambium
meristem that -->es rows in cells in stem and root
how does cell increase in lenghth by division?
apical meristem
procambium cells
will eventually change to vascular cells
parts of apical meristem
apical meristem - how increases in length

protoderm - changes to epidermis
leaf promordia - main leaf

procamibum - eventual change to vascular (phloem and xylem)

ground meristem --> ground tissue

2nd part----primary tissue

ground tissue (from ground meristem)

ptih cortex - tissue b/t vascular and epidermis -->es cork cambium

primary xylem and primary phloem (from procambium)

also procambium to vascular camibum

epidermis (from protoderm)

3rd part ----lateral meristem

vascular cambium (from procamibum of primary meristem)- -->es vascular tissue, (2ndary phloeum and xyleum)

cork camibum --> cork in periderm


pith - composed of parinkama cells (basic plant cells

ALL PLANTS ARE *PRIMARY TISSUES* - CAME FROM APICAL MERISTEM
can distinguish b/t leaves b/c of ______
arrangement
arrangement of leaves
alternate
opposite
whirl - 3+ at 1 node
3 major parts of a plant
vascular tissue - has conducting cells (xylem and phloem) may be fibers and dividing cells

ground tissue - support tisue or differentiation

dermal tissue - layer cells exterior, epidermis
