Definition

Describing something that is fixed in one place and does not move, often used in biology to refer to plants or animals that are attached directly to a surface without a stalk.

Example

The sessile leaves of the plant grow directly from the stem without any stalks.

Conversation

Have you seen those plants with sessile leaves in the garden?

Yeah, they look interesting! I wonder how they grow like that.

I read that sessile plants are usually more stable in windy conditions.

That makes sense! Being low to the ground helps them survive better.

Root Explanation

Sessile → It is derived from the Latin "sessilis" (meaning sitting or settled), which comes from "sedere" (meaning to sit). The term describes organisms that are fixed in one place and do not move, as if they are sitting.

Memory Tip

Think of something that is 'sitting' in one place — that's why 'sessile' refers to organisms that are fixed and do not move.
