The rudimentary spermatophyte contained within a viable seed. |
|
embryo sac |
< megagametophyte |
STRUCTURE |
|
The multinucleate generative cell of an ovule, within which fertilization and zygote formation occur; resulting from meiotic division of a megaspore mother cell within the nucellus, and thus genetically haploid; its contents generally considered to represent an evolutionarily reduced gametophyte. |

STRUCTURE |
|
The innermost tissue layer of a pericarp. |
|

habit |
|
Growing within some portion of another, unrelated, living plant. |
|
endosperm |
= albumen |
STRUCTURE / SUBSTANCE |
|
A genetically triploid (3n chromosomes) nutritive tissue in a seed; containing stored carbohydrate and/or oil utilized by the embryo prior to and especially upon germination; derived from fusion of the two polar nuclei (n + n chromosomes) of the embryo sac with a sperm nucleus from the pollen tube (n chromosomes). See also perisperm. |
|
enlarged |
|
size |
|
Unusually or unexpectedly large. |
|

prefix |
|
Indicating presence of or constitution by nine entities of the type denoted by the term's stem; as in enneandrous, enneafoliolate, enneastylous. |
|
ensate |

plane shape |
|
Elongate and moderately slender, broadest at the base and gradually attenuate to a short, more strongly attenuate, acute apex; like the outline of the lateral face of a broadsword blade. |
|
ensiform |
= sword-shaped |
solid shape |
|
Elongate and moderately slender, strongly compressed, the opposite faces plane, parallel, broadest at the base and gradually attenuate to a short, more strongly attenuate, acute apex; like a broadsword blade. |
|
entire |
|
margin |
|
Uninterrupted; not deviating significantly from its general line, thus lacking any localized convexities or concavities. |
