drupelet

/'dru:plit/

Thân thiện

A ripe blackberry is covered in tiny, juicy drupelets.

Definition

Noun: A drupelet is a small, individual unit of an aggregate fruit. Each drupelet is structurally similar to a drupe (a fleshy fruit with a single hard stone or pit surrounding the seed), meaning it typically consists of a thin skin, a fleshy middle layer, and a hard inner layer enclosing a single seed. Drupelets are clustered together to form the complete fruit.

Usage

The term "drupelet" is used specifically in botany to describe the small, seed-bearing subunits that make up certain aggregate fruits. It is a technical term.

Examples

• The surface of a raspberry is covered in many tiny, juicy drupelets.
• Each drupelet in a blackberry contains its own small seed.
• Botanists study how drupelets develop and fuse together to form the aggregate fruit.

Advanced Usage

• Botanical Description: In precise botanical terminology, an aggregate fruit like a raspberry is an aggregation of drupelets from a single flower with multiple pistils. When you pick a raspberry, the central core (the torus or receptacle) remains on the plant, leaving a hollow fruit because the drupelets separate from it.

Variants and Related Words

• Drupe (noun): The type of fruit that a drupelet resembles. A drupe is a simple fruit with one seed enclosed in a hard endocarp (e.g., a peach, cherry, or olive). An aggregate fruit is a cluster of many small drupes (drupelets).
• Aggregate Fruit (noun): A fruit that develops from a single flower with multiple separate pistils, resulting in a cluster of small fruits. The individual small fruits are the drupelets (in fruits like raspberries) or achenes (in fruits like strawberries).

Synonyms

• Particle (in a general, non-botanical sense for a very small part)
• Unit (in a structural sense)

Note: There are no direct, common-language synonyms for this precise botanical term. "Seed section" or "tiny fruit segment" are descriptive approximations but not technical synonyms.
