Difference between endosperm seeds and non-endosperm seeds

Main difference

The main difference between Endospermous Seeds and Non-Endospermous Seeds is that Endospermous Seeds have seeds with endosperm, while Non-Endospermous Seeds have seeds without endosperm.

Endosperm seeds vs. non-endosperm seeds

Endosperm seeds are dicotyledonous and monocotyledonous, while non-endosperm seeds are dicotyledonous. In endosperm seeds, seed food is stored in the endosperm, while in non-endosperm seeds, seed food is stored in cotyledons. The cotyledons of endosperm seeds are thin and papery; conversely, the cotyledons of non-endosperm seeds are thick and fleshy.

Endosperm seeds have endosperm; on the other hand, the seeds of the non-endosperms have no endosperm. The perisperm of endosperm seeds does not grow from nucellus; in contrast, non-endosperm seed perisperm grows from nucellus. The haustoria and the suspensor of the endosperm seeds do not retain the endosperm present in the seeds; on the other hand, the haustoria and the non-endosperm seed suspensor protect the endosperm.

Endosperm seeds take their nutrients and food from the endosperm, while non-endosperm seeds take their nutrients and food from the outside. Examples of endosperm seeds are corn, castor bean, etc .; On the other hand, some examples of non-endosperm seeds are beans, peas, cucurbita, squash, etc.

What are endosperm seeds?

The term endosperm seeds refers to seeds that have seeds within their seeds. In other words, seeds that at maturity express the existence of endosperm in their seeds are known as endosperm seeds. In many seeds, the endosperm is absorbed by the endosperm seeds at maturity. Endosperm seeds get their nutrients and food from the endosperm.

When plant embryos grow, the supply of basic food and nutrients is vital to them. So, in many plants, various tissues are present that act as a food store for the plants by absorbing most of the seed. This store is generally known as an endosperm. As endosperm seeds grow and mature, the embryonic leaves, which are produced by endosperm seeds, feed on the endosperm for growth and nutrition. A common example of an endosperm is found in wheat.

Cotyledons also help nourish the embryo when it germinates. The cotyledons of endosperm seeds are thin and papery and help absorb stored food from the endosperm. The haustoria and the suspensor of the endosperm seeds do not retain the endosperm present in the seeds.

The perisperm of endosperm seeds does not grow from nucellus. Endosperm seeds are dicotyledonous and monocotyledonous. Endosperm seed types are monocots and dicots. Examples of endosperm seeds are corn, castor bean, etc.

What are non-endosperm seeds?

The term non-endosperm seeds generally refers to seeds that do not have seeds within their seeds or seeds that, when mature, do not show the presence of endosperm in their seeds are known as non-endosperm seeds. Non-endosperm seeds take their nutrients and food from the outside. Embryonic leaves, generally called cotyledons (stores non-endosperm seed food), are produced by non-endosperm seeds.

They cover most of the space in the seed and as these cotyledons are stored, the food takes up nutrients that will help nourish the growing embryo, which means that the endosperm seed food is present in the cotyledons, not in its seeds. The haustoria and the suspensor of the non-endosperm seeds protect the endosperm. The perisperm of non-endosperm seeds generally grows from nucellus.

The seeds of the non-endosperm are dicotyledonous. The non-endosperm seed type is only dicotyledonous. Some common examples of non-endosperm seeds are beans, peas, cucurbita, squash, etc.

Key differences

  1. Dicots and monocots are considered endosperm seeds, while dicots are non-endosperm seeds.
  2. The endosperm is the food reservoir in endosperm seeds, while the cotyledons are the food reservoir in non-endosperm seeds.
  3. Cotyledons are thin and papery in endosperm seeds; conversely, cotyledons are thick and fleshy in non-endosperm seeds.
  4. The endosperm is present in the seeds of endosperms; on the other hand, there is no endosperm present in the seeds of endosperms.
  5. The perisperm of endosperm seeds does not usually develop directly from nucellus; in contrast, the non-endosperm seed perisperm develops directly from nucellus.
  6. The haustoria and suspensor endosperm seeds do not take their energy from the endosperm found in the seeds; on the other hand, the seeds not haustoria and suspensor endosperms do not take energy from the endosperm found in the seeds.
  7. Endosperm seeds get their nutritious food from the endosperm core, while non-endosperm seeds get their nutritive food from other than the endosperm core.
  8. Examples of endosperm seeds are corn, castor bean, etc .; On the other hand, some examples of non-endosperm seeds are beans, peas, cucurbita, squash, etc.
Final Thought

The above discussion concludes that endosperm seeds have seeds with endosperm and seed food is stored in the endosperm, while non-endosperm seeds have seeds without endosperm and seed food is stored in cotyledons.
