name for young plant that is able to survive without its cotyledons
seedling
plants that have nonwoody stems
herbaceous
this part of the stamen produces pollen grains
anther
the transfer of pollen from the stamen to the top of the pistil
pollination
this type of plant reproduction does not involve flowers, seeds, or fruit
vegetative (reproduction)
the parts of a flower that attract pollinators
petals
tiny one-celled reproductive structures found on plants such as ferns
spores
the place where a leaf attaches to the stem
node
this forms after a pollen grain reaches a flower, and sperm cell travels to egg cell
pollen tube
this carries water from root hairs upward to the leaves
xylem
the type of flowers usually found in the center of a composite flower head
disk
water is absorbed through the cell membrane of the root hairs by…
osmosis
the storage cells that surround a root’s transport tubes form the…
cortex
birds and other animals can aid in this type of dispersal of seeds
agent (dispersal)
plants without vascular systems are called…
bryophytes

seed coat
growth of a plant in length is this type of growth
primary
the upward force in the transport tubes produced by water entering the root hairs
root pressure
essay: contrast the four major characteristics of monocots (M) and dicots (D)
- M=one cotyledon; D=two
- M=long, slender leaf; parallel veins
D=broad leaves with branching veins - M= petals in groups of 3
D= petals in groups of 4 or 5 - M=fibrous root system
D=taproot system
