lendospermo

Lendospermo is a term that may appear in some botanical writings as a nonstandard spelling or regional variant of endosperm, the nutritive tissue inside seeds of flowering plants. In contemporary English-language botany, the preferred term is endosperm.

Endosperm is produced after double fertilization: one sperm fertilizes the egg to form the embryo, while another sperm fuses with the two polar nuclei to form a triploid tissue that nourishes the developing embryo during seed formation. The endosperm can serve as the primary storage tissue in many seeds and varies in its persistence and degree of development among major plant groups.

Structure and development: Endosperm development can be cellular, nuclear, or cellularized, depending on the species. In many monocots, the endosperm remains substantial in the mature seed and provides a large reservoir of starch and other nutrients. In many dicots, the endosperm is reduced or absorbed by the embryo before seed maturation.

Function and composition: The primary role of the endosperm is to supply nutrients during germination and early seedling growth. Its composition typically includes carbohydrates (especially starch), along with lipids and proteins. Some seeds store most nutrients in the embryo itself rather than in the endosperm.

Distribution and terminology: Endosperm is widespread among angiosperms but is not uniform across all seeds; some seeds have little or no persistent endosperm. Because lendospermo is not a standard term, readers should verify usage against a reliable source, as it may reflect a typographical error or regional spelling.
