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.
A vascular bundle is a part of the transport system in vascular plants. The transport itself happens in vascular tissue, which exists in two forms: xylem andphloem. Both these â¦ tissues are present in a vascular bundle, which in addition will include supporting and protective tissues. vascular bundle is a strand of vascular tissue in leaves, young plants, and nonwoody stems. The strand is the xylem and phloem.
