tissue that conducts water and nutrients through the plant body in higher plants
Specialized cells to conduct water, key cells in xylem.
a transport subsystem that carries water upward from the roots to every part of the plant
transports solutions of nutrients and carbohydrates produced by photosynthesis
underground organs that absorb water and minerals
photosynthetic organs that contain one or more bundles of vascular tissue
vascular tissue that is gathered
supporting structures that connect roots and leaves, carrying water and nutrients between.
creeping or underground stems
large leaves found on ferns
haploid spores on the underside of their fronds in tiny containers that are sporangia
clusters of sporangia
multicellular eukaryotes that have cell walls made of cellulose.
develop from multicellular embryos and carry out photosynthesis using the green pigments chlorophyll a and b.
Diploid (2N) phase
the sporophyte, or spore-producing plant.
The haploid (N) phase
the gametophyte, or gamete-producing plant.
In order to survive, plants need:
water and minerals
transport of water and nutrients throughout the plant body
Plants are divided into groups based on these features:
Bryophytes or nonvascular plants
do not have vascular tissues, or specialized tissues that conduct water and nutrients.
The three groups of bryophytes
adapted to life in wet habitats and nutrient-poor soils, can tolerate low temperatures, and are clumps of gametophytes growing together.
can be cut from the ground and used as fuel.
specialized to conduct water and nutrients throughout the plant.
a transport subsystem that carries water from the roots to every part of a plant.
transports solutions of nutrients and carbohydrates produced by photosynthesis.
vascular tissues, strong roots, underground stems found in ferns
bear seeds directly on the surfaces of cones.
Angiosperms or flowering plants
bear seeds within a layer of tissue that protects the seed.
are the seed-bearing structures of gymnosperms.
are the seed-bearing structures of angiosperms.
a tiny structure where the male gametophyte is contained.
the process for the transfer of pollen where sperm does not need water to fertilize eggs; instead the pollen grain is carried to the female reproductive structure by wind, insects, or small animals.
an embryo of a plant that is encased in a protective covering and surrounded by a food supply.
an organism in its early stage of development.
surrounds and protects the embryo and keeps contents of the seed from drying out.
palmlike plants that reproduce with large cones.
include pines, spruces, firs, cedars, sequoias, redwoods, junipers, and yews.
a wall of tissue that surrounds a seed.
the first leaf or the first pair of leaves produced by the embryo of a seed plant.
Three categories of plant life spans
annual, biennial, and perennial.
plants that complete a life cycle in one growing season.
complete their life cycle in two years. In the first year, they germinate and grow roots, short stems, and sometimes leaves.
live for more than two years.
