An organism or cell having two sets of chromosomes
An organism or cell having only one complete set of chromosomes
Alternation of Generations
The alternation between the haploid gametophyte and the diploid sporophyte in a plant's life cycle
A process used by plants and other autotrophs to capture light and energy and use it to power chemical reactions that convert carbon dioxide and water into oxygen and energy-rich carbohydrates, such as sugars and starches.
A moss, liverwort, or hornwort; a nonvascular plant that inhabits the land but lacks many of the terrestrial adaptations of vascular plants (vascular tissue).
Spore-producing plant; the multicellular diploid phase of a plant life cycle
Spore capsule in which haploid spores are produced by meiosis
The stage in the life cycle of a plant in which the plant produces gametes, or sex cells.
Threadlike structures that anchor nonvascular plants in place
Produced by meiosis. Grow into haploid organisms by mitosis.
Female reproductive part of nonvascular and seedless vascular plants
Structures in plants that produce male gametes
Nonliving vascular tissue that carries water and dissolved minerals from the roots of a plant to its leaves
Living vascular tissue that carries sugar and organic substances throughout a plant
Plants that have transport vessels, xylem and phloem - term for the seedless vascular plants
Structures that, along with tracheids, make up xylem
A water-conducting and supportive element of xylem composed of long, thin cells with tapered ends and walls hardened with lignin.
A type of cell found in phloem
Make up phloem vessels, along with sieve tube elements
The leaf of a fern plant
Young fern sporophyte that has its fronds curled up
Horizontal stems in club mosses and ferns, can periodically reproduce (asexual)
Sporangia at tip of club mosses
Structures found on sperm sporophytes that contain clusters of sporangia
Group of plants that includes the gymnosperms and angiosperms and is characterized by the production of seeds.
Group of seed plants that produce 'naked seeds'
3 phyla of gymnosperms
Gingkophyta, Cycadophyta, Coniferaphyta
Phylum of gymnosperms characterized by fan-shaped leaves
Phylum of gymnosperms that are palm-like trees that produce cones
Largest phylum of gymnosperms that are typically evergreen, softwood, cone-bearing species.
Waxy outerlayer of leaves that prevents water loss found in the seed plants.
The transfer of pollen from the male parts of a plant to the female parts of the plant (not the same thing as fertilization).
Haploid nutritious tissue that nourishes the developing embryo. Haploid in gymnosperms and triploid in angiosperms.
Female cone of conifers.
Male cone of conifers
Common term for the male gametophyte in conifers
Diploid part of a seed that provides protection to the developing embryo and is derived from the integument of the ovule.
Parts of a gymnosperm seed
Embryo (diploid), endosperm (haploid, derived from female gametophyte), seed coat (diploid, derived from integument)
Refers to the shape of the leaves on conifers. Their thin shape helps them survive the snowy winters and the dry, windy conditions.
The group of plants that produce covered seeds.
Often brightly coloured flower structures that serve to attract pollinators.
Often green petals that form the outer layer of a flower and protect the developing bud.
Sticky upper lip that captures pollen.
Structure that supports the stigma.
Collective term for the female parts of a flower.
Collective term for the male parts of a flower.
Structure that supports the anther.
Pollen-producing structure on a flower.
Structure that surrounds the seed that develops from the ovary.
Structures within the ovary in which the egg develops. Turns into a seed.
Term for the male gametophyte in gymnosperms and angiosperms.
Term for the female gametophyte in angiosperms.
The ploidy of the endosperm in angiosperms.
Refers to the fertilization of the egg by one sperm and the polar nuclei of another sperm that occurs in angiosperms.
Refers to the two central nuclei within the embryo sac. These fuse with a sperm to produce the endosperm.
Term for the outer layer of the ovule, which develops to form the seed coat after fertilization occurs.
Swollen structure at the base of the pistil. Develops into the fruit.
The process in which the next generation of plants are transported away from the parent plant. Achieved by spores in mosses and ferns and by seeds in the seed plants.
