Vascular plants are any plant thatAproduces seeds.Bcan grow taller than 10 m.Ccontains xylem and phloem.Dpassively absorbs water from the environment.

The correct answer is C. Vascular plants are defined by the presence of specific tissues, known as xylem and phloem, which are used for the transportation of water, nutrients, and sugars throughout the plant. This system allows vascular plants to grow larger and live in a wider range of environments compared to non-vascular plants.

Option A is incorrect because not all vascular plants produce seeds. For example, ferns and clubmosses are vascular plants that reproduce via spores.

Option B is incorrect because the height of a plant is not a defining characteristic of being a vascular plant. There are many small vascular plants, such as certain types of ground cover and flowering plants.

Option D is incorrect because while vascular plants do absorb water from their environment, they do not do so passively. The xylem and phloem systems actively transport water and nutrients from the roots to the rest of the plant.
