∙ 13y agoThe tracheids, fibres, and vessels present in the xylem, become lignified during development, losing their living contents. This makes the tissue impermeable (to water) so none is lost as water is transported via the xylem. The tracheids' bordered pits allow for the rapid movement of water from cell to cell.
As is with tracheids, the lignification of vessels can occur as rings, spirals, scalariform or reticulate. In the first formed xylem, rings and spirals occur more frequently. This allows for a limited amount of stretching which may occur in young structures.
Both tracheids and vessels provide a pathway for the transportation of water, whilst also contributing to support.

Function of phloem parenchyma?
The parenchyma cells in between the sieve tubes of the phloem, and functions primarily for food storage.
Epithelial cells are specialized for all the following functions?
Without knowing what the functions are a person will have difficulty knowing which are specialized for epithelial cells. Including the functions would insure that a person will provide the correct answer.
Why are animal cells specialized?
Both animals and plants normally begin life as a single cell, the zygote, because that is how sexual reproduction takes place. (Asexual reproduction can happen in different ways.) Since the organism starts with one cell, the various specialized types of cells must necessarily form in the course of embryonic development (except in the case of unicellular organisms which, having only one cell, also have only one kind of cell). The purpose of specialized cells is also clear. By specializing, it is possible for a cell to do a specific function more efficiently than an unspecialized cell could. An organism made up of specialized cells is a much more effective organism, with greater capabilities.
Through what process do cells become specialized so they can perform specific functions within organisms?
Through what process do cells become specialized so they can perform specific functions within organisms?
The cells of multicellular organisms are often?
specialized to perform particular functions
What tissue in plants is made of specialized cells that transports nutrients from the leaves to other areas of the plant?
Phloem is made of sieve tubes, companion cells and phloem parenchyma. These are specialized cells to transport nutrients from leaves to other area of the plant.
Which structures make up phloem?
Phloem tissue consists of: conducting cells, generally called sieve elements; parenchyma cells, including both specialized companion cells or albuminous cells and unspecialized cells; and supportive cells, such as fibres and sclereids.(attribution: wikipedia, Phloem)
What are Cells that have their own unique structures and functions?
It is called a differentiation
Function of phloem parenchyma?
The parenchyma cells in between the sieve tubes of the phloem, and functions primarily for food storage.
What are two examples of tissue found in plants?
xylem and phloem are the two tissues of plants. 2. lignins and cellulose perhaps.
What two kinds of cells that perform specialized functions in humans?
Neurons, sarcomeres, osteoblasts, and cardiac muscle cells all have specialized functions performed by no other cells.

Examples of specialized animal cells?
Specialized animal cells are cells found in animals that perform specific functions and only those specific functions. Examples include nerve cells, muscle cells and red blood cells.
Why is it good to have specialized cells?
It is good to have specialized cells because it gives a more wide variety of functions to perform. :) :) :) :) :) :) :) :) :) :) :)
