Nodes, buds, meristems and crowns

See it

Nodes contain attachment points and often axillary buds; shoot tips include actively growing tissue; meristematic regions contain actively dividing cells; crowns are compact growing regions in some plants such as strawberry. These terms are related but not interchangeable.

Understand it

A nodal explant can include an axillary bud positioned to develop into a shoot.
Meristem culture can be used for specialized objectives and is not the same as ordinary nodal culture.
Crown-based material in strawberry has a different morphology from a simple woody stem node.
Important boundary

Use the exact anatomical term supported by the source or protocol.

Try it

Explain the concept in your own words, then identify what plant, explant, stage, units, source, or observation context would need to be preserved before applying it.
