Difference Between Endospermous Seeds and Non-Endospermous Seeds

ADVERTISEMENT

Main Difference

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

Endospermous Seeds vs. Non-Endospermous Seeds

The endospermous seeds are dicots and monocots, while the non-endospermous seeds are dicots. In endospermous seeds, the food of seeds is stored in the endosperm, whereas in non-endospermous seeds, the food of seeds is stored in cotyledons. The cotyledons of endospermous seeds are thin and papery; on the contrary, the cotyledons of non-endospermous seeds are thick and fleshy.

The seeds of endospermous have endosperm; on the other hand, the seeds of non-endospermous are without endosperm. The perisperm of endospermous seeds does not grow from nucellus; conversely, the perisperm of non-endospermous seeds grow from nucellus. The haustoria and suspensor of endospermous seeds do not standby the endosperm present in seeds; on the flip side, the haustoria and suspensor of non-endospermous seeds standby the endosperm.

The endospermous seeds take their nutrients and food from the endosperm, while non-endospermous seeds take their nutrients and food from outside. The examples of endospermous seeds are maize, castor, etc.; on the other hand, some examples of non-endospermous seeds are bean, pea, Cucurbita, squash, etc.

What are Endospermous Seeds?

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

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

The cotyledons also help in nourishing the embryo when it germinates. The cotyledons of endospermous seeds are thin and papery and aids in absorbing the stored food from the endosperm. The haustoria and suspensor of endospermous seeds do not standby the endosperm present in seeds.

The perisperm of endospermous seeds does not grow from nucellus. The seeds of endospermous are dicots and monocots. Types of endospermous seeds are monocots and dicots. The examples of endospermous seeds are maize, castor, etc.

What are Non-Endospermous Seeds?

The term non-endospermous seeds generally refer to the seeds that do not have seeds within their seeds or the seeds that, when gets mature, do not show the presence of endosperm in their seeds is known as non-endospermous seeds. Non-endospermous seeds take their nutritious and food from outside. The embryonic leaves, usually called cotyledon (stores the food of non-endospermous seeds), are produced by non-endospermous seeds.

They cover most of the space in the seed, and as these cotyledons store, the food becomes occupied with nutrients that will help in nurture the growing embryo, which means that the food of endospermous seeds is present in cotyledons not in their seeds. The haustoria and suspensor of non-endospermous seeds standby the endosperm. The perisperm of non-endospermous seeds usually grows from nucellus.

The seeds of non-endospermous are dicots. The type of non-endospermous seeds is only dicots. Some common examples of non-endospermous seeds are bean, pea, Cucurbita, squash, etc.

Key Differences

  1. Dicots and monocots are considered as the endospermous seeds, while dicots are the non-endospermous seeds.
  2. The endosperm is the food reservoir in endospermous seeds, whereas the cotyledons are the food reservoir in non-endospermous seeds.
  3. The cotyledons are thin and papery in the endospermous seeds; on the contrary, the cotyledons are thick and fleshy in the non-endospermous seeds.
  4. The endosperm is present in the seeds of endospermous; on the other hand, no endosperm is present in the seeds of endospermous.
  5. The perisperm of endospermous seeds usually not develop directly from the nucellus; conversely, the perisperm of non-endospermous seeds develops directly from nucellus.
  6. Endospermous seeds haustoria and suspensor do not take its energy from the endosperm found in the seeds; on the flip side, non-endospermous seeds haustoria and suspensor do not take energy its energy from the endosperm found in the seeds.
  7. The endospermous seeds obtain their nutritious food from the endosperm nucleus, while, non-endospermous seeds obtain their nutritious food from other than the endosperm nucleus.
  8. The examples of endospermous seeds are maize, castor, etc.; on the other hand, some examples of non-endospermous seeds are bean, pea, Cucurbita, squash, etc.

Conclusion

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