cotyledon etymology

Etymology:

The word "cotyledon" is derived from the Greek words:

• kotyledon ("cavity")
• -on (diminutive suffix)

Meaning and Origin:

The term "cotyledon" refers to an embryonic leaf found in the seeds of most flowering plants. It is typically the first leaf to emerge from the seed during germination.

The original Greek word "kotyledon" was originally used to describe the cavity or hollow part of a cup or bowl. Over time, it came to be applied to the seed leaf because it often has a concave or "hollow" shape. The diminutive suffix "-on" indicates that it is a small or secondary leaf.

Usage:

Cotyledons are important in plant classification and identification. The number, shape, and arrangement of cotyledons can vary among different plant families and species.

• Dicotyledons (Dicots): Plants that have two cotyledons in their seeds.
• Monocotyledons (Monocots): Plants that have a single cotyledon in their seeds.
