An embryonic leaf in seed-bearing plants that are usually the first leaves to appear from the germinating seed
Used for transferring haploid male genetic material from the anther of a single flower to the stigma of another
Cell that contains the same number of chromosomes as a zygote; two sets of chromosomes
A sporangium that produces spores that give rise to male gametophytes
Stem of a germinating seedling, found below the cotyledons (seed leaves) and above the radicle (root)
the part of a plant embryo that develops into the primary root
Used as collective term for parts of a flower that produce ovules & develop into fruit & seeds ('female' part of flower)/innermost whorl of one or more pistils/produces megaspores
Plant cells found within the mesophyll in leaves of many plants, right below the upper epidermis and cuticle, that contain numerous chloroplatsts
The process of the joining together of a single female gametophyte with two male gametes
The receptive tip of the pistil that receives the pollen at pollination
Pairs of cells that surround the stoma that help to regulate the rate of transpiration
A slim, cyclindrical flower cluster with no petals, usually wind- pollinated but somtimes insect- pollinated, and they contain many unisexual flowers along a ccentral drooping stem
The gamete-producing and usually haploid phase of the life cycle of alternation of generations that produces the zygote from which the sporophyte arises
Photosynthetic cells arranged into tightly packed casings around the veins of a leaf
Number of sets of chromosomes in the nucleus of a cell
Commonly used to describe the life cycle of plants; the alternation between a gametophyte and a sporophyte
A thread-like chain of cells that forms the earliest stage of a bryophyte
The structure that gives rise to and contains the female reproductive cells
The leaf or leaflike part of a palm, fern, or similar plant
Protective outer layer of a seed
A root that arises from any point other than the radicle or the root axis, any unusual location
cells and organisms that have three sets of paired chromosomes
The female reproductive part of a flower; composed of the stigma, style, and ovary
Cell that contains the same number of chromosomes as a gamete; one set of chromosomes
The arrangement of the veins in a leaf
A flowering plant with an embryo that bears a single seed leaf
A long, slender stalk that connects the stigma and the ovary
Any of the various kinds of hard, woody cells that serve the function of support in plants
A small, dry one-seeded fruit that does not open to release the seed
Part of a seed that acts as a food (energy) source for the developing plant embryo/triploid embryonic tissue
The asexual and usually diploid phase in the life cycle of alternation of generations that produces spores from which the gametophyte arises
Collective name for all sepals of a plant
A modified berry with a tough, leathery rind
A flowering plant with an embryo that bears two seed leaves
Non-reproductive part of the flower/structure that forms envelope around sexual organs/made up of calyx & corolla
A winged nut or achene containing one seed
Also known as murein, a polymer consisting of sugars and amino acids that forms a mesh-like layer outside the plasma membrane, forming the cell wall
Plant that grows harmlessly upon another plant and derives its moisture and nutrients from air, rain, and debris around it/have no negative effect on host(not parasitic)
Collective term for group of stamens ('male' parts) of a flower/normally surrounds the gynoecium & is surrounded by perianth
Cluster of spore-producing structures (sporangia) usually located on the lower surface of fern leaves
A fleshy fruit produced from a single flower and containing one ovary
Collective name for the petals of a flower
An indehiscent fruit in which an outer fleshy part surrounds a shell of hardened endocarp with a seed inside
A fruit consisting of a fleshy enlarged receptacle and a tough central core containing the seeds
Ususally the gametophyte stage in the life of a fernor other pteridophyte. May also be used to describe the young gametophyte of a liverwort or peat moss
Outer layer of a fleshy fruit/tissue that develops from ovary wall of flower & surrounds the seeds
Type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus
The pointed protective sheath covering the emerging shoot in monocotyledons
the tip of the stamen that contains the pollen
Type of cell division that results in four daughter cells each with half the number of chromosomes of the parent
The peripheral surface of the pericarp in citrus fruits/Composed of several cell layers that become progressively thicker
