Is an northern white cedar a angiosperm?

No, the northern white cedar (Thuja occidentalis) is not an angiOSperm; it is a gymnosperm. AngiOSperms are flowering plants that produce seeds enclosed within a fruit, whereas gymnosperms, like the northern white cedar, produce seeds that are not enclosed and typically develop in cones. Northern white cedar is part of the cypress family and is known for its coniferous characteristics.
