The first leaf or leaves in the seed. In some plants the cotyledons remain underground in the seedcoat.

(Gr., hollow of a cup) one of the rounded parts into which the uterine surface of the placenta is divided.

The hard outer case of the seed which holds the embryo (baby part of the plant) and gives it a food supply.

the initial leaves on a plant germinant.

A rudimentary leaf of the embryo.

a leaf-forming part of the embryo of a seed plant. Monocotyledons have one and dicotyledons have two cotyledons in each seed.

The first seed leaf to appear after germination of a seed.

The one (monocot) or two (dicot) seed leaves of an angiosperm embryo.

The endosperm of the seed, one in monocotyledons two or more in dicotylendons.

The fetal portion of the placenta in animals such as cattle and sheep.

In dicotyledonous plant species, the initial growth stage characterized by the presence of "seed leaves." These leaves initially contained in the seed and provide food for seed germination.

The seed leaf of a plant embryo. Monocots have one cotyledon and dicots have two cotyledons.

the part of a seed that forms the first leaves.

The seed leaves of the embryo which serve as a food reserve used during germination, and may act as leaves before the development of the first true leaves.

the first leaves on a seedling providing the new seedling with food until it can produce its own

(Greek, kotyle = a deep cup) In the embryos of seed plants, the "seed leaves," in which nutrients are stored for use after germination. Used also to describe the structure of the placenta. (More? Placenta Notes) cr - cy

the embryo leaf or leaves of seed plants that absorbs nutrients packaged in the seed, until the seedling is able to produce its first true leaves and begin photosynthesis. "The number of cotyledons present in an embryo is an important character in the classification of flowering plants (angiosperms). Monocotyledons (such as grasses, palms, and lilies) have a single cotyledon, whereas dicotyledons (the majority of plant species) have two. In seeds that also contain endosperm (nutritive tissue), the cotyledons are thin, but where they are the primary food-storing tissue, as in peas and beans, they may be quite large. After germination the cotyledons either remain below ground (hypogeal) or, more commonly, spread out above soil level (epigeal) and become the first green leaves. In gymnosperms there may be up to a dozen cotyledons within each seed." Tiscali. Image from the Online Biology Book by Dr. Mike Farabee of Estrella Mountain Community College.

One of the rounded portions into which the placenta's uterine surface is divided, consisting of a mass of villi, fetal vessels, and an intervillous space.

The first or "seed" leaf of a seed plant. [AV

a type of seed leaf

part of seed surrounding the embryo, the cotyledon serves as a source of nutrients for the germinating plant. The number of cotyledons in the seed serves as a basis for classifying angiosperms into monocotyledons, with one cotyledon, and dicotyledons, with two.

An embryo leaf that usually serves as the major food reserve for dicot seedlings May absorb food for seedling growth

seed leaves first leaves that appear on a plant.

A seed leaf; the first leaf of a germinating seed

The first developing leaves produced by a germinating seed.

the embryo leaf or leaves of seed plants that usually stores or absorbs food in a young seedling; in angiosperms (flowering plants) the following distinction is made with respect to the cotyledons: di cots have two cotyledons and mono cots have one cotyledon

seed leaf; a modified leaf present in the seed, often functioning for food storage.

one of the first pair of leaves in an embryo, seen following germination (seed leaf)

first seedling leaf or leaves

The first leaf or leaves to be carried by a seedling after germination. Cotyledons are often different in appearance from subsequent and adult leaves.

A leaf-like structure that is present in the seeds of flowering plants; appears during seed germination and sometimes is referred to as a seed leaf. PICTURE

n. (Gr. kotyle, a hollow or cavity) the first leaf or leaves of a seed plant, found in the embryo of the seed which may form the first photosynthetic leaves or may remain below ground.

a leaf of the embryo of a seed plant, which upon germination either remains in the seed or emerges, enlarges, and becomes green. Also called seed leaf

A primary leaf; generally stores food in dicotyledons and absorbs food in monocotyledons.

the placenta is divided into 15-20 by septa (invaginations of maternal decidua), but are not thought to represent discrete functional placental units

The "seed leaf" or first leaf which emerges from the seed.

the primary leaf (or one of two or more primary leaves) of an embryo.

kot i le don A seed leaf (Greek kotyledon, from kotyle a cup)

First leaf-like structures that appear after germination; seed leaves.

One of the first leaves to appear after germination (there may be one, two, or more); the foliar portion of the embryo as found in the seed. See also: true leaf.

Seed leaves; the first pair of leaflike structures, usually paired, appearing above ground in most dicotyledonous plants.

The seed leaves, which are present before germination, as distinct from true leaves, which develop after germination.

( kòt´l-êd´-n) - The first leaf that appears on a seedling. Also known as a seed leaf.

Embryonic leaf.

the endosperm in a seed that develops into a seedling.

n. The "seed leaves" produced by the embryo of a seed plant that serve to absorb nutrients packaged in the seed, until the seedling is able to produce its first true leaves and begin photosynthesis; the number of cotyledons is a key feature for the identification of the two major groups of flowering plants.

the first leaf of a seed plant. It is already formed in the seed but may or may not appear above ground, depending on the species.

Part of the seed from which the seedling draws food. In some cases it is a storage organ, in others it absorbs food from the endosperm for use by the seedling. See Seed Starting: Germination

first leaf of a plant from seed.

A "seed leaf" of a plant, which either stores or absorbs food. Whether a species has one or two marks the great division of the flowering plants ( Angiosperms) into the Monocots and Dicots.

Portions of the stratum compactum persist and are condensed to form a series of septa, which extend from the basal plate through the thickness of the placenta and subdivide it into the lobules or cotyledons seen on the uterine surface of the detached placenta.
