Correct option is A
Explanation:
Phelloderm is a type of tissue that is produced by the cork cambium, also known as phellogen. The cork cambium is a lateral meristem that produces phellem (cork) on the outside and phelloderm on the inside. It is a part of the periderm, which replaces the epidermis in secondary growth in plants. The phelloderm is a thin layer of living parenchyma cells that lies beneath the cork layer.
Information Booster:
Cork cambium produces the outer protective layer of the plant, which includes both phellem (cork) and phelloderm.
The phelloderm is typically composed of living parenchyma cells and serves to protect the plant.
Cork cambium originates from the pericycle or cortex and is responsible for the formation of the outer protective layers in woody plants during secondary growth.
Additional Knowledge:
Fascicular cambium (option 2) is responsible for the production of vascular tissues (xylem and phloem) in the vascular bundles, not for the production of phelloderm.
Interfascicular cambium (option 3) forms in the region between vascular bundles and helps produce secondary xylem and phloem, not phelloderm.
Provacular tissue (option 4) is a general term for tissue in the plant where vascular tissue develops, but it is not specifically involved in the formation of phelloderm.
