Xylem (blue) transports water and minerals from the roots upwards. Xylem is one of the two types of transport tissue in vascular plants, the other being phloem. The basic function of the xylem is to transport water from roots to stems and leaves, but it also transports nutrients.
Runcaria has all of the qualities of seed plants except for a solid seed coat and a system to guide the pollen to the ovule. [99] The first spermatophytes (literally: "seed plants") – that is, the first plants to bear true seeds – are called pteridosperms : literally, "seed ferns", so called because their foliage consisted of fern-like ...
Vascular tissue is a complex conducting tissue, formed of more than one cell type, found in vascular plants. The primary components of vascular tissue are the xylem and phloem. These two tissues transport fluid and nutrients internally. There are also two meristems associated with vascular tissue: the vascular cambium and the cork cambium.
Non-vascular plants are plants without a vascular system consisting of xylem and phloem. Instead, they may possess simpler tissues that have specialized functions for the internal transport of water. [citation needed] Non-vascular plants include two distantly related groups: treat as three separate land-plant divisions, namely: Bryophyta ...
Seed dispersal. In spermatophyte plants, seed dispersal is the movement, spread or transport of seeds away from the parent plant. [1] Plants have limited mobility and rely upon a variety of dispersal vectors to transport their seeds, including both abiotic vectors, such as the wind, and living ( biotic) vectors such as birds.
Vascular plants (from Latin vasculum 'duct'), also called tracheophytes (/ t r ə ˈ k iː. ə ˌ f aɪ t s /) or collectively tracheophyta (/ t r ə ˈ k iː. ə f aɪ t ə /; from Ancient Greek τραχεῖα ἀρτηρία (trakheîa artēría) 'windpipe', and φυτά (phutá) 'plants'), form a large group of land plants (c. 300,000 accepted known species) that have lignified tissues ...
A stem is on of two main structural axes of a vascular plant, the other being the root. It supports leaves, flowers and fruits, transports water and dissolved substances between the roots and the shoots in the xylem and phloem, photosynthesis takes place here, stores nutrients, and produces new living tissue. [1]
A leaf ( pl.: leaves) is a principal appendage of the stem of a vascular plant, [1] usually borne laterally aboveground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", [2] [3] while the leaves, stem, flower, and fruit collectively form the shoot system. [4]
