Root Hair Cell Labelled Diagram Simple

The root hairs are where most water absorption happens. A root hair or absorbent hair the rhizoid of a vascular plant is a tubular outgrowth of a trichoblast a hair forming cell on the epidermis of a plant root as they are lateral extensions of a single cell and only rarely branched they are visible to the naked eye and light microscope. The structure of a root hair cell differs from other root cells in that it has a long thin extension supported by the central vacuole which greatly increases its surface area.

As you read please refer the words in bold to the basic hair structure and hair follicle diagrams below.

Root hair cell labelled diagram simple. Each hair arises from an indentation on the epidermis. Since h air growth is basically just a collection of dead cells being pushed along a pouch follicle in the skin it s important to learn about skin structure and function too. Hair is made up of two parts the hair follicle and the hair shaft. The latter lubricates the passage of root through the soil.

The hair bulb is the structure formed by actively growing cells. They are long and thin so they can penetrate between soil particles and they have a large surface area for absorption of water. Plants absorb water from the soil by osmosis. Directly behind the root cap is the root meristem which is where cell division occurs this means that when the root grows the new cells come from the root meristem.

The terminal part of the hair follicle within the skin is called a hair bulb. Behind this growing region is 3 the root hair or piliferous region. This is the part of the root which actually grows. A look at the structure and function of the root hair cell an example of a specialised plant cell.

Root hair cells are adapted for this by having a large surface area to speed up osmosis. Like other root cells it has a thick cell wall huge central vacuole and is separated from other root cells by a thin layer of cytoplasm. It is a thimble shaped or cap like parenchymatous multicellular structure which covers the root meristem. They are found only in the region of maturation of the root.

The cells of the root cap secrete mucilage. Without it the tender root would be unable to penetrate the hard soil. Some parts of the hair follicle diagram are also color coded to highlight their importance. Just behind the root cap is 2 the very short growing region.

This is a labelled diagram of a root hair cell. Cells of the root cap also possess starch grams. This region may be further subdivided into the zones of division and elongation according to the stage of growth of the cells. Key stage three bitesize revision.

This clip is from. The hair follicle is the point from which the hair grows. The function of the root hair cell is to obtain water from the ground and transport this to the xylem.
