A group of plants with one embryonic leaf (cotyledon) in the seed.

A group of plants with two embryonic leaves (cotyledons) in the seed.

An embryonic leaf that is often swollen with nutrients to nourish the seed.

Specialized cotyledon of a monocot, absorbs endosperm nutrients.

Food storage tissue in a seed.

The undeveloped plant within the seed.

Grasses, including important crops like wheat and corn.

The process by which a seed begins to grow into a plant.

Plants with one cotyledon (seed leaf) per seed.

Plants with two cotyledons (seed leaves) per seed.

Leaf veins run parallel to each other.

Leaf veins form a net-like or branched pattern.

A specialized layer of cells in dicots that increases plant girth.

A mature seed from a grass plant grown for harvest.

Pronounced 'Po-A-C-E', like spelling the letters 'A', 'C', 'E'.

Three main parts: plumule (shoot), radicle (root), and scutellum (cotyledon).

The primary root of a plant embryo, first part to emerge from a seed.

A sheath-like structure protecting the radicle of grass embryo.

The root system from the radicle and lateral seminal roots in grass seedlings.

The embryonic shoot of a plant that develops above ground.

Small growth point located between embryonic leaves of the shoot.

Main sustaining root system in grass, forms from the coleoptilar node.

The dried ovary wall that forms the outermost layer of a cereal grain (caryopsis).

A layer of high-protein cells beneath the seed coat, playing a role in digesting endosperm reserves.

Protective outer covering of a seed.

Consists of radicle (embryonic root), plumule (embryonic shoot), and two cotyledons.

The combined outer layers (pericarp, testa, and aleurone layer) of a cereal grain.

The endosperm tissue in dicot seeds is absorbed into the cotyledons during seed development, leaving the cotyledons to store food.

The scar on the seed coat where it was attached to the fruit.

A small hole in the seed coat that allows moisture entry during germination.

A type of seed germination where cotyledons remain below the soil surface.

A type of seed germination where cotyledons are raised above the soil surface.

The part of the stem located directly above the cotyledons. It's responsible for pushing the plumule (first true leaves) through the soil during hypogeal germination.

The part of the stem located directly below the cotyledons. It's responsible for pushing the cotyledons up through the soil during epigeal germination.
