AP BIOLOGY

Detailed explanation-1: -Common club moss, also known as running pine or stag’s horn moss (Lycopodium clavatum), has creeping stems up to 3 metres (about 10 feet) long and has 10-cm-(about 4-inch-) high ascending branches. The scalelike green leaves are set closely together.

Detailed explanation-2: -Clubmoss get their name from the resemblance of their tiny leaves to leaves of mosses, and from the fact that their spores are produced in club-like branches called strobili. Like ferns, clubmosses never have flowers.

Detailed explanation-3: -The same species photographed wild in Vermont. Some club mosses go by the common name “ground pine” because they resemble miniature conifer trees with their scaly or needle-like leaves.

Detailed explanation-4: -They are not true mosses, which are non-vascular. Clubmosses are larger and taller. Clubmoss reproduction occurs through the dispersal of spores, found in sporangia, located singly or in groups, or in a yellow cone-like tip known as a strobilus. It can take up to 20 years for a clubmoss to mature and produce spores.
