1 The structure of an egg An egg is a reproductive cell from which a new organism develops. 2  This will occur only if the egg has been united with a male sperm cell (fertilized). 3  A chick will hatch from a fertile egg if the egg is incubated at 100.5 degrees F for 21 days.
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.All the vascular tissues within a particular plant together constitute the vascular tissue system of that plant. The cells in vascular tissue are typically long and slender.Since the xylem and phloem function in the conduction of water, minerals, and nutrients throughout the plant, it is not surprising that their form should be similar to pipes.he vascular tissue in plants is arranged in long, discrete strands called vascular bundles. These bundles include both xylem and phloem, as well as supporting and protective cells. In stems and roots, the xylem typically lies closer to the interior of the stem with phloem towards the exterior of the stem.
Hyponyms (each of the following is a kind of vascular plant): nonflowering plant; pteridophyte (plants having vascular tissue and reproducing by spores). ligneous plant; woody plant (a plant having hard lignified tissues or woody parts especially stems).eronyms (parts of vascular plant): vascular system (the vessels and tissue that carry or circulate fluids such as blood or lymph or sap through the body of an animal or plant). duct (a continuous tube formed by a row of elongated cells lacking intervening end walls).
