Question

what is what is the difference between an embryo and a seed

Answer 1

A seed is a small embryonic plant enclosed in a covering called the seed coat, usually with some stored food. It is the product of the ripened ovule of gymnosperm and angiosperm plants which occurs after fertilization and some growth within the mother plant.

An embryo is a multicellular diploid eukaryote in its earliest stage of development, from the time of first cell division until birth, hatching or germination. In humans, it is called an embryo until about eight weeks after fertilization (i.e. ten weeks after the last menstrual period or LMP), and from then it is instead called a fetus.
