Quick Answer: Which Of The Following Is An Endospermic Seed?

Why are non Albuminous seed so called?

Solution : The seeds in which the endosperm is used up during embryo development are called exalbuminous seeds such as bean , pea and gram.

These seeds usually store food materials in cotyledons..

Where is food stored in Albuminous seeds?

Answer: (1) The endosperm is not completely consumed during embryo development, and it is the nourishing tissues in seeds. In beans, peas, gram seeds, the endosperm is completely absorbed during development and food is stored in two cotyledons. They are called exalbuminous seeds.

Is Orchid Endospermic seed?

Answer: (b) Orchid seed is a non-endospermic seed, i.e., endosperm is absent in it. … Nourishment for germinating seed is provided by the food material present in cotyledons. Rest of the options are examples of endospermic seeds.

How many of these are not example of Endospermic seeds?

Non-endospermic seeds are Jack fruit, Mustard, and Sunflower. In these seeds, the cotyledons contain the reserve food.

What is Endospermic seed?

Endosperm, tissue that surrounds and nourishes the embryo in the seeds of angiosperms (flowering plants). In some seeds the endosperm is completely absorbed at maturity (e.g., pea and bean), and the fleshy food-storing cotyledons nourish the embryo as it germinates.

Which one of the following is an Endospermic or Albuminous seed?

castor beanHence, ‘castor bean’ with others, are called ‘endospermic’ or ‘albuminous’ seeds. In wheat the ‘endosperm’ is selectively retained in food processing (commonly called wheat flour) and the ’embryo’ (germ) and seed coat (bran) are removed, while castor bean is the source of castor oil (uses in medicine).

Which Monocot seed is non Endospermic?

Mostly monocots have endospermic or albuminous seed and dicots have non-endospermic seed. But one of the exceptions is Alisma seed which is a monocot plant but with non-endospermic seed. Thus, the correct answer is ‘Alisma.

Which one of the following is non Endospermic seed?

Non-endospermic seeds or exalbuminous seeds have no residual endosperm as it is completely consumed during embryo development. Gram, pea, bean and groundnut have non-endospermic seeds.

Is Pea Endospermic seed?

Most species of the legume family (Fabaceae) including pea (Pisum sativum) and diverse beans have non-endospermic seeds. The cotyledons serve as sole food storage organs as in the case of pea (Pisum sativum). During embryo development the cotyledons absorb the food reserves from the endosperm completely.

Is Rice a monocot or dicot?

Monocotyledons or monocots commonly refer to the flowering plants or angiosperms in which the seeds typically contain only one embryonic leaf or cotyledon….MonocotDicotRicePumpkinMaizePea1 more row

What are Albuminous seeds?

Seeds with an endosperm at maturity are termed albuminous seeds. Most monocots (e.g. grasses and palms) and many dicots (e.g. brazil nut and castor bean) have albuminous seeds. All gymnosperm seeds are albuminous. The seed coat develops from the tissue, the integument, originally surrounding the ovule.

Are all Dicot non Endospermic?

Seeds having endosperm is called as endospermic seed. Seeds without endosperm is called as non-endospermic seed. Example of plant having endospermic dicot seed is Ricinus communis (Castor). Example of plant having non-endospermic dicot seed is Pisum sativum (Pea).

What is Albuminous and non Albuminous?

Albuminous seeds refer to those seeds that retain or restores some part of the endosperm during embryonic development. Examples include maize, barley, castor, and sunflower. Non-albuminous seeds refer to those seeds that consume the entire endosperm during the embryonic development. Examples include peas and groundnut.

What is Endospermic and non Endospermic seed?

Endospermic seeds are those which seed enosperm is located outside of cotyledons and cotyledons are tiny or leafy, ex: castor bean seeds. Cotyledon seeds or non-endospermic seeds are those which seed endosperm is absorbed by cotyledons and hence cotyledons are swollen, ex: bean seed.

Which one of the following seed is Albuminous?

Solution : Albuminous seeds are found in wheat, maize, barley, castor and sunflower.

What is Endospermic seed examples?

Here are the examples of endospermic and non-endospermic seeds:Monocotyledon endospermic seed. – Zea mays. – Barley. – Rice. – Wheat. … Dicotyledonous endospermic seed. – Castor. – Cotton. – Coffee.Monocotyledon non-endospermic seeds. – Potthos sp. – Vallisnaria sp.Dicotyledonous non-endospermic seeds. – Pea. – Bean. – Gram. – Bean.

Is wheat a Endospermic seed?

In most monocots and some dicot seeds, the food reserve remains in the endosperm. They are called endospermic or albuminous seeds. e.g., maize, wheat, castor bean, coconut, barley, rubber. … They are called nonedospermic or exalbuminous seeds.

Is not an Endospermic seed?

In most monocots and some dicot seeds, the food reserve stays in the endosperm. They are known as endospermic or albuminous seeds, e.g., maize, wheat, castor bean, coconut, barley, rubber. … They are called non-endospermic or exalbuminous seeds. So, the right answer is (a) ‘Pea’.

What is non Albuminous seed?

Non albuminous seeds are the seeds which have the stored food and the cotyledons in a special structure called as kernel. It does not remain until the embryo is mature. e.g. Pea seed.

Which of the following is Monocot seed?

Corn, wheat and rice, are examples of monocot seeds or monocotyledons. Embryos of a monocotyledonous seed possess only one large cotyledon called scutellum.

Is coconut Dicot or Monocot?

Botanically, the coconut palm is not a tree since there is no bark, no branches, or secondary growth. A coconut palm is a woody perennial monocotyledon with the trunk being the stem.
