Question

What provides a food reserve in dicot (eudicot) seeds?

Answer 1

Endosperm, all flowing plants have this food reserve in their seeds.

- Dicots are plants that have two embroyonic leaves that sprout from the seed and they are all flowering plants.

- Monocotyledons are plants that have 1 embroyonic leaf that sprouts from the seed.

- Eudicots or tricolpates. These may be distinguished from all other flowering plants by the structure of their pollen.

According to Wikipedia:  

"The form of the stored nutrition varies depending on the kind of plant. In angiosperms, the stored food begins as a tissue called the endosperm, which is derived from the parent plant via double fertilization. The usually triploid endosperm is rich in oil or starch and protein."

According to Wikipedia:

"Dicotyledons, or "dicots", is a name for a group of flowering plants whose seed typically has two embryonic leaves or cotyledons. There are around 199,350 species within this group. Flowering plants that are not dicotyledons are monocotyledons, typically having one embryonic leaf."

According to Wikipedia:

"The flowering plants or angiosperms are the most widespread group of land plants. The flowering plants and the gymnosperms comprise the two extant groups of seed plants. The flowering plants are distinguished from other seed plants by a series of apomorphies, or derived characteristics."

According to Wikipedia:  

"Monocotyledons or monocots are one of two major groups of flowering plants (angiosperms) that are traditionally recognised, dicotyledons or dicots being the other. "
