|
The female gametophyte of angiosperms (flowering plants). Same as megagametophyte. |
|
|
Embryotega
|
A small circular thickening near the seed scar on the seeds of some plants; e.g., Commelinaceae. |

Árbol del bosque cuya copa sobresale del dosel superior. Este término también se aplica a las plantas acuáticas cuyas partes y órganos emergen sobre la superficie del agua. |
|
|
Empheral
|
A temperate zone plant that sends out leaves and photosynthesizes in the spring before the leaves of the trees appear. During this time the plant produces and stores enough carbohydrate to allow it to flower the following spring. Not long after flowering, the plant wilts and remains inconspicuous until the next spring. |

|
Endosperm
|
