antherium
male reproductive structure where sperm develops in the male gametophyte
vascular plant
contain vascular tissues specially adapted to transport water and dissolved nutrients
vascular plant
contain vascular tissues specially adapted to transport water and dissolved nutrients
archegonium
female reproductive structure that develops eggs in the female gametophyte
stomata
openings in leaf epidermis to release H2O and O2 and take in CO2 for respiration and photosynthesis
cuticle
waxy coating on outer surface of epidermis of most fruits, stems and leaves
stem
plant structure that provides support for leaves and reproductive structures
leaf
plant organ that provides surface area for trapping sunlight and exchanging gases through stomata during photosynthesis
root
plaant organ normally found below ground that anchors the plant
nonvascular plant
plants that lack vascular tissue to efficiently transport water and nutrients
cone
woody strobili of gymnosperms
xylem
tissue composed of dead tubular vessels or tracheids laid end to end transports water and minerals
cotyledon
storage organ of the embryo of an angiosperm (flowering plant)
vascular tissue
tissue that transports water, food and other nutrients throughout the plant
deciduous plant
looses all leaves at the same time so can no longer perform photosynthesis and remains dormant during winter
rhizome
underground horizontal stem of vascular plalnts for food storage
embryo
early stage of growth and development of a plant or animal that followed fertilization of an egg by a sperm cell and the formation of a zygote
pollen grain
found in seed plants, the protective structure in which the male gametophyte develops, contains nutrients for sperm cell
evergreen plant
plant that retains its leaves year round
phloem
found in vascular plants; transports sugar
frond
leaflike organ of a fern that grows upward from the rhizome
gymnosperm
non-flowering vascular plants with seeds that form on woody reproductive structures that form cones
angiosperm
flowering plants whose seeds are contained in fruit
transpiration
evaporation of H2O from the stomata of leaves
apical meristem
terminal growth tissue of roots and stems that add new cells for growth in length (the tips of branches)
petiole
leaf part that joins leaf blade to stem
bark
outer layer of a woody stem that includes phloem tissue
perennial
a flowering plant that lives for several years
cambium
mytotic growth layer in vascular plants that can produce both xylem and phloem cells
monocotyledon
plant with flower parts in multiples of three seeds with one cotyledon and parallel leaf veins such as grass and orchids
dicotyledon
plant with flower parts in multiples of 4 or 5, seeds with 2 cotyledons, and branching network of veins in the leaves such as garden fowers and herbs
anther
pollen bearing part of the stamen in a floweringplant male reproductive structure in which sperm containing pollen grains develp and burst from when mature
stamen
a flower's male reproductive organ that produces male gametophytes and pollen grains
petal
leaflike flower organs
pistil
flowering plants female reproductive organ that produces female gametophytes and is attached to the top of the flower stem
