AP BIOLOGY

Detailed explanation-1: -Horsetail occurs in woods, fields, meadows and swamps, and moist soils alongside streams, rivers, and lakes, and in disturbed areas. It usually occurs on moist sites but can also be found on dry and barren sites such as roadsides, borrow pits, and railway embankments.

Detailed explanation-2: -Horsetail and scouring rush are most commonly found in poorly drained areas, such as roadsides, wetlands and drainage ditches. The preference for wet areas is due to the requirement for a moist environment during establishment with spores.

Detailed explanation-3: -Horsetail grows in wet conditions and can even grow in standing water. For this reason, it is commonly used to decorate water gardens or swampy areas where few other plants can survive.

Detailed explanation-4: -The energy they gather through photosynthesis goes to underground tubers for storage, allowing horsetail to survive harsh winters and periods of drought.
