FAQ
Frequently Asked Questions
No. Meristem is the undifferentiated, dividing cell region (the 'factory'). Primary tissue is the differentiated product (e.g., epidermis, primary xylem) that results from meristem activity.
The term is less common in animal anatomy but can be used to refer to tissues derived directly from the three primary embryonic germ layers (ectoderm, mesoderm, endoderm).
In a young plant undergoing only primary growth, yes, essentially all tissues are primary tissues. Once secondary growth begins (e.g., in tree trunks), secondary tissues like wood and bark are added.
The direct antonym is 'secondary tissue', which is tissue produced later from lateral meristems (like the vascular cambium), leading to thickening in plants.
