eukaryotic
Having cells that contain a nucleus and membrane-bound organelles
photosynthesis
Process of using the sun's energy to make "food" in the form of glucose
producer
Organism that produces food, such as glucose, for itself and other organisms
angiosperm
Flowering plant with vascular tissue, seeds, and flowers
gymnosperm
Plant with vascular tissue and seeds but no flowers
nonvascular plant
Plant without vascular tissue
seedless vascular plant
Plant with vascular tissue but no seeds or flowers
bryophyte
Type of plant that lacks vascular tissues, such as a liverwort, hornwort, or moss
gametophyte
Haploid (having one set of chromosomes) generation in the life cycle of a plant
hornwort
Nonvascular plant with long and pointed sporophytes, like tiny horns
liverwort
Nonvascular plant that has leaf-like or ribbon-like bodies
moss
Tiny nonvascular plant that grows like carpets and has leaf-like structures
nonvascular seedless plant
Plant without vascular tissue or seeds
sporangium
Capsule that releases spores in mosses
sporophyte
Diploid (having two sets of chromosomes) generation in the life cycle of a plant
vascular tissue
Specialized tissue that transports water, nutrients, and food in plants
club moss
Vascular seedless plant that looks similar to the nonvascular moss, but with true roots, stems, and leaves
fern
Vascular seedless plant with large divided leaves called fronds
horsetail
Vascular seedless plant with hollow, ribbed stems; it is often found in marshes
vascular seedless plant
Plant with vascular tissue but no seeds or flowers
whisk fern
Vascular seedless plant with green branching stems, yellow spherical sporangia, and no leaves
conifer
Plant that bears seeds in cones and has evergreen needle-like or scale-like leaves
Cycad
Palm-like plant bearing large male or female cones and found in tropical regions
ginkgo
Chinese tree with broad, fan-shaped leaves
gnetophyte
Subdivision of woody plants consisting of three living genera and approximately 70 species; link between conifers and angiosperms
pollen
Powder-like substance; it contains gametophytes that produce the male gamete of seed plants
angiosperms
Plants that produce flowers and fruits
anther
Structure that contains pollen in a flower
calyx
All of the sepals together, or the outside of the flower
carpel
"Female" part of the flower; it includes the stigma, style, and ovary
corolla
Petals of a flower collectively
cross-fertilization
Pollen from one flower travels to a stigma of a flower on another plant
filament
Stalk that holds up the anther
ovary
Large, bottom part of the carpel where the ovules are contained
ovules
Part of the ovary that is the female gametophyte; after fertilization, ovules become the seed
pollen
Powder-like substance; it contains gametophytes that produce the male gamete of seed plants
pollinator
Animal, such as a bird or an insect, that carries pollen from one flower to another
self-pollination
Pollen falls on the stigma of the same flower
sepal
Green outside of the flower
stamen
Part of the flower that produces pollen
stigma
Part of the carpel on which the pollen must land for fertilization to occur
style
Tube that makes up part of the carpel
