Vascular plant
Vascular plant
A vascular plant (/væˈskjʊlər plænt/), also known as tracheophyte (/ˈtreɪkiəˌfoʊt/), is a type of plant that possesses specialized tissues, known as xylem and phloem, for conducting water, minerals, and photosynthetic products. The term "vascular" is derived from the Latin vasculum, meaning "small vessel".
Etymology
The term "vascular" comes from the Latin vasculum, meaning "small vessel". This refers to the plant's vascular system, which includes the xylem and phloem. The term "tracheophyte" comes from the Greek words tracheia, meaning "windpipe", and phyton, meaning "plant". This term was coined due to the resemblance of the plant's vascular system to a windpipe.
Classification
Vascular plants are part of the kingdom Plantae. They are further classified into two main groups: the seed plants, which include gymnosperms and angiosperms, and the spore plants, which include ferns and lycophytes.
Anatomy
The main distinguishing feature of vascular plants is the presence of a vascular system, which includes the xylem and phloem. The xylem is responsible for the transport of water and minerals from the roots to the rest of the plant, while the phloem transports sugars and other metabolic products from the leaves to the other parts of the plant.
Reproduction
Vascular plants reproduce either by spores or by seeds. Spore-producing vascular plants include ferns and lycophytes, while seed-producing vascular plants include gymnosperms and angiosperms.
