Vascular plants
Vascular plants
Vascular plants (pronunciation: /ˈvæskjʊlər plɑːnts/), also known as tracheophytes (pronunciation: /ˈtrækiːəˌfaɪts/), are a large group of plants that are defined by the presence of vascular tissue. The term "vascular" comes from the Latin word "vasculum", meaning "small vessel".
Etymology
The term "vascular" is derived from the Latin word "vasculum", which means "small vessel". This refers to the plant's vascular tissue, which includes the xylem and phloem. These tissues are responsible for the transport of water, nutrients, and sugars within the plant.
