- Identify the plant structure specified by a protocol
- Explain why tissue selection matters
- Document intentional tissue substitutions

Tissue culture begins with real plant structures. Nodes, buds, shoot tips, leaves, roots, embryos, crowns, and meristematic regions differ in developmental role and regenerative behavior. Learning where these structures are located helps a grower understand why a protocol specifies a particular explant.
Understand it
Identify the plant structure specified by a protocol
Anatomy gives meaning to protocol language.
Anatomy connects a protocol's tissue description to the actual structure selected from a plant.
Explain why tissue selection matters
Young actively growing tissues may behave differently from mature tissues.
Developmental state can affect regenerative behavior; tissues should not be treated as equivalent solely because they share a plant name.
Document intentional tissue substitutions
The visible plant structure selected should be recorded clearly.
A tissue-specific method begins by identifying its specified structure, not by substituting an easier piece silently.
Worked example
A grower has a leaf and a shoot tip available. The source describes a shoot-tip method. The grower first identifies the required structure; using the leaf would be a different test, not the same method.
Explain your decision before opening the worked reasoning below.
Show the worked reasoning
Documenting an intentional substitution keeps the changed biological material visible in later comparisons.
Structure and tissue state are relevant biological differences that a plant name alone cannot describe.
Do not substitute a different tissue merely because it is easier to collect unless the protocol or experiment intentionally tests that change.
