Question

What factors contribute to the varying degrees of endosperm consumption in dicotyledons and monocotyledons during post-fertilization events in angiosperms? Is the involvement of suspensor cells, particularly in pushing the developing embryo into the endosperm, a determining factor, or are there other influences at play?

Answer 1

The varying degrees of endosperm consumption in dicotyledons and monocotyledons during post-fertilization events in angiosperms are influenced by factors such as the involvement of suspensor cells and whether the plant is endospermic or non-endospermic. In endospermic dicots, the food reserves are stored in the endosperm and are absorbed by the cotyledons during germination, while in non-endospermic dicots, the endosperm is quickly remobilized and the food reserves are directly moved into the developing cotyledon for storage.

Step-by-step explanation:

The varying degrees of endosperm consumption in dicotyledons and monocotyledons during post-fertilization events in angiosperms can be attributed to several factors. One important factor is the involvement of suspensor cells, which provide a route for nutrition to be transported from the mother plant to the growing embryo. The suspensor cells also play a role in pushing the developing embryo into the endosperm. Another factor that influences endosperm consumption is whether the plant is endospermic or non-endospermic. In endospermic dicots, the food reserves are stored in the endosperm and are absorbed by the cotyledons during germination. In non-endospermic dicots, the endosperm is quickly remobilized and the food reserves are moved into the developing cotyledon for storage.
