Question

which one dose develop into fruit after fortilization ?

Answer 1

Seeds and Fruits

The seeds and fruits are the results of fertilization or sexual reproduction in plants. The ovary in angiosperms develops into the fruit whereas the ovules become the seeds enclosed within the fruit. Seeds are found both in gymnosperms and angiosperms. Let us individually learn about seeds and fruits.

Fruits

One of the many healthy things available in the world today is fruits. They are mostly sweet to taste, are filled with nutrients and some of them are like tomatoes are considered as vegetables. The fruit is broadly divided into the pericarp which is the various covering layers of the fruit and the seed or seeds which are present inside it. The pericarp of a fruit can be further divided including

Exocarp– It is the outermost layer which is formed from the outer layer or the epidermis

Mesocarp– Is the second or the middle layer which is often juicy and varies in thickness in different fruits

Endocarp– It is the innermost layer and also is different in different fruits.

Development of a Fruit

As mentioned earlier, once pollinationand fertilization occur, the zygote is formed and the ovary begins to differentiate into the fruit. The outer wall of the ovary begins to differentiate into the pericarp whereas the seed develops within the fruit itself.

Types of Fruits

Fruits can be classified in many ways.

True and False Fruits

Simple, Aggregate, and Multiple Fruits

Simple fruits are further classified as fleshy and dry fruits depending on their appearance

True and False Fruits

True Fruits- True fruits are those that are formed solely from the ovary with ovules inside it. No other flower parts form a part of this type of fruit.

False Fruits-False fruits are formed from the ripened ovary along with some other flower parts like the base or receptacle, the perianth etc.

Simple, Aggregate, Multiple and Accessory Fruits

Simple Fruits

These fruits are formed from a single pistil only. They are further divided into Fleshy and Dry fruits based on the nature of their pericarp and its layers.

I. Fleshy Fruits

Fleshy fruits, as the name mentions, have a fleshy and juicy pericarp. They are further of many different types:

Drupe- In this type of fleshy simple fruit, the exocarp is thin, the mesocarp is thick and juicy while the endocarp is stony. Examples of such fruits are mango, plum, and coconut.

Berry- In this type of fleshy fruits, the endocarp is absent and the seeds are scattered in the mesocarp. Examples are grapes, banana, tomato.

Pome- Is a false fruit as the thalamus forms a part of the fruit. Examples of this type of fruit are apples, pears.

II. Dry fruits

Dry fruits do not have juicy or thick pericarps and are of two types.

Dehiscent dry fruits

These fruits burst on their own to release the seeds.  They are of many types:

Follicle- These fruits are formed from a single carpel and dehisce along one suture or margin only. Ex: Calotropis

Legume- These fruits are formed from a single carpel and dehisce along both sutures. Ex: legumes, beans

Capsule- Is formed from multiple carpels. It has many pores or chambers in it and it dehisces by splitting into many parts to release seeds. Example: Lady’s Finger

Siliqua-It is formed by two carpels and dehisces from the base upwards with the seeds attached to the base itself. Example: mustard

Indehiscent dry fruits

These fruits do not dehisce or burst to release the seeds.  They are of many types:

Achene: Is single-seeded and the seed coat is separate from the fruit coat or pericarp. Example: Magnolia

Caryopsis: Is similar to the achene except that the seed coat and the fruit coat are united or fused. Example: Maize

Samara: One-seeded fruit with wings. Example: Hiptage, Ash

Nut:  One-seeded fruit with a stony pericarp. It may contain husk on its wall as well. Example: Oak, Chestnut

Cypsela: Is formed from a bicarpellary inferior pistil. It is also one-seeded. Example: Sunflower

Aggregate Fruits

These fruits are developed from an aggregate or cluster of multiple separate pistils that are borne on a single flower. This aggregate or group of fruits that are developed from a single flower are known as an etaerio. Example: Raspberry.

Multiple Fruits

When an entire inflorescence develops into a single fruit, it is called a multiple fruits.  Example: Pineapple, figs, mulberry, jackfruit.
