+Summary: Validates if the ARC contains the necessary metadata to describe conditions for plant growth.
+Description: |
+    Validates if the ARC contains an annotation table with protocol type "Plant Growth Protocol" and if it exists, whether it contains the following fields:
+
+        Critical fields:
+        - organism (OBI:0100026)
+        - growth day length (DPBO:0000041)
+        - light intensity exposure (PECO:0007224)
+        - humidity day (DPBO:0000005)
+        - temperature day (DPBO:0000007)
+        - temperature night (DPBO:0000008)
+        - watering exposure (PECO:0007383)
+
+        Non critical fields:
+        - genotype (EFO:0000513)
+        - study type (PECO:0007231)
+        - Reference Time Point (NCIT:C82576)
+        - growth plot design (DPBO:0000001)
+        - plant growth medium exposure (PECO:0007147)
+        - humidity night (DPBO:0000006)
+        - plant nutrient exposure (PECO:0007241)
+        - abiotic plant exposure (PECO:0007191)
+        - biotic plant exposure (PECO:0007357)
