A Correct answer
Explanation

The seed which store food material in cotyledons are called exalbuminous seed.

A. Pea-exalbuminous  seed.
B. Castor- albuminous  seed.
C. Bean- albuminous  seed.
D. Gram- albuminous  seed.
So, the correct answer is 'Pea'.

Multiple choice botany pollination, fertilization and development of endosperm and embryo fruits and seeds fruit and its type fertilization events

In exalbuminous seed, the food is generally stored in

  1. Endosperm initially but hypocotyl later on.

  2. Cotyledons

  3. Endosperm from the beginning

  4. Testa

B Correct answer
Explanation

1. Seed store reserve food for the use of embryo at the time of germination in their cotyledons or in endosperm.

2. The seeds, which store food materials in their cotyledons are called non- endospermic or exalbuminous seeds( e.g., Gram, Pea).
3. The seeds, which store food materials in endosperm are called  endospermic or albuminous seeds( e.g., Castor, Maize).
4. Testa- The outer coat of seed is called testa.
So, the correct answer is 'Cotyledons'.

Multiple choice botany pollination, fertilization and development of endosperm and embryo fruits and seeds fruit and its type fertilization events

In exalbuminous seeds, there is :

  1. Non formation of endosperm

  2. Abundant formation of endosperm

  3. Abundant protein

  4. Consumption of endosperm during development of speed

D Correct answer
Explanation

Seed store reserve food for the use of embryo at the time of germination in their cotyledons or in endosperm.

The seeds, which store food materials in their cotyledons are called non- endospermic or exalbuminous seeds( e.g., Gram, Pea).
The seeds, which store food materials in endosperm are called  endospermic or albuminous seeds( e.g., Castor, Maize).
So, the correct answer is 'Consumption of endosperm during development of embryo'.

Multiple choice botany pollination, fertilization and development of endosperm and embryo fruits and seeds fruit and its type fertilization events

Which one is monocot albuminous seed?

  1. Maize

  2. Wheat

  3. Rice

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Seeds, which store food materials in their cotyledons are called non- endospermic or exalbuminous seeds.(e.g., Gram, Pea, Bean, Almond, Groundnut).

Seeds, which store food materials in their endosperm are called endospermic or albuminous seeds. (e.g., Castor, Maize, Wheat, Barley, Grasses).

Monocot seed- one cotyledon.

Dicot seed- Two cotyledons.

A. Maize- Monocot albuminous seed.

B. Wheat- Monocot albuminous seed.

C. Rice- Monocot albuminous seed.

So, the correct answer is 'All of the above'.

Multiple choice botany pollination, fertilization and development of endosperm and embryo fruits and seeds fruit and its type fertilization events

Aleurone layer takes part in

  1. Protein of delicate embryo

  2. Enzyme synthesis

  3. Transfer of food to cotyledons

  4. Transfer of food from cotyledons to embryo tips
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In monocotyledonous endospermic seed, endosperm is surrounded by a special one- cell thick layer, called aleurone layer. Its main function is to nourish the embryo enclosed in the seed.It is protein rich coat formed by the outermost layer of endospermic cells. It actively secretes few enzymes which help in the process of seed germination.
So, the correct answer is 'Enzyme Synthesis'.

Non-albuminous seeds occur in

  1. Maize

  2. Wheat

  3. Rice

  4. <p>Vallisneria</p>
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Seeds, which store food materials in their cotyledons are called non- endospermic or exalbuminous seeds.(e.g., gram, pea, bean, almond, groundnut, mustard, sunflower).

Seeds, which store food materials in their endosperm are called endospermic or albuminous seeds. (e.g., castor, maize, wheat, barley, grasses, rice).

Vallisneria is a genus of freshwater aquatic plant, commonly called eelgrass, tape grass or vallis.  It has a non albuminous seed.

So, the correct answer is 'Vallisneria'.

Seed of castor is

  1. Non-endospermic exalbuminous

  2. Endospermic albuminous

  3. Endospermic exalbuminous

  4. Non-endospermic albuminous
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Seeds, which store food materials in their cotyledons are called non- endospermic or exalbuminous seeds.(e.g., Gram, Pea, Bean, Almond, Groundnut).

Seeds, which store food materials in their endosperm are called endospermic or albuminous seeds. (e.g., Castor, Maize, Wheat, Barley, Grasses).

So, the correct answer is 'Endospermic albuminous'.
