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 .
What else can I help you with?
Do seeds and spores have both multicellular and embryos?
While they have the same function- to reproduce- the main difference between seeds and spores is that seeds come from flowering plants (they are the ripened ovules of the plants) and spores are produced by non-flowering plants (they are tiny reproductive bodies). Seeds, since they are ripened ovules, have plant embryos with a food store and a protective covering around all of that. On the other hand, spores do not have stored food resources and can be made of one or many cells. So, seeds are multicellular while spores are usually unicellular, and seeds contain embryonic plants while spores do not (they themselves are the tiny reproductive bodies).
Where are embryo located in flowering plants?
Embryos in flowering plants are located within seeds, which develop from the fertilized ovules within the ovary. The embryo is typically located within the embryo sac of the seed and consists of the plant's future root, shoot, and cotyledons.
What are artificial seeds?
Artificial seeds are encapsulated plant tissue cultures that behave like seeds. They are produced by encapsulating somatic embryos, shoot buds, or any other tissues that can be induced in vitro. These artificial seeds provide a means for handling, storing, and transporting plant materials efficiently.
What exactly is a seed and how do they help plant success?
seed consists of an embryo packaged along with a store of food within a protective coat. seeds contributed to the embryos to be dispersed without drying out.
Why are seeds and spores different sizes?
Seeds are typically larger than spores because seeds contain nutrients to support the growth of a new plant, while spores are smaller and designed for dispersal over long distances. Seeds are essentially plant embryos, enclosed in protective coats, while spores are single cells that can develop into a new organism under suitable conditions.
Do seeds and spores have multicellular embryos?
no
What the fertilization?
the seeds and embryos and pollen
How many embryos do the seeds of monocots have?
1 embro
What fertilize the ovule?
SEED
Why do seeds contain embryos?
Seeds contain embryos to provide an energy source for the plant when it starts to shoot out of its seed. Think of it like the yoke for a chicken inside an egg. The yoke is the embryo of the egg.
What are undeveloped seeds in a flower?
Ovules before fertilzation, embryos after fertilization
What type of embryos have pharngeal slits?
All chordates embryos have pharngeal slits.
What two things do all growing embryos need?
the 2 things that ALL growing embryos need are food and oxygen
What are undeveloped seeds in a flower called?
Ovules before fertilzation, embryos after fertilization

Do all organisms start out as embryos?
No, not all organisms start out as embryos. Embryos are typically seen in higher animals that undergo sexual reproduction, where a fertilized egg develops into an organism. Organisms like bacteria and protists reproduce asexually and do not have an embryonic stage in their life cycle.
Do early chick and pig embryos have a similar structure and appearance?
The early embryos of all animals have a very similar appearance. This is no different for chicken and pig embryos.
