What is the structure of root hair cell?
What is the structure of root hair cell?
The root hair cell is roughly rectangular in shape with a cytoplasmic extension on its lateral end (the root hair). It has the following cellular components: A cell wall with intercellular spaces. A semi-permeable cell membrane.
What is the function of root hair cell?
Root hair cells (black arrow pointing at one of the root hair cells) are single tubular root cells. Their distinctive lateral elongation increases the surface of exchange between the plant’s root system and the soil. The main function of root hairs is the uptake of water and nutrients from the rhizosphere.
What is P in the above diagram biology?
The label P is the nucleus of the cell which is placed at the periphery due to the presence of the large vacuole.
Why is the root hair cell that shape?
Root hair cells have a very large surface area due to them being very long and having hair like projections. This allows more active transport of mineral ions to take place so the plant is able to take in as many important mineral ions as possible e.g. nitrates.
What is the structure of the roots?
Typical roots contain three different sections, or zones: the meristematic zone, the zone of elongation, and the zone of differentiation. In the meristematic zone, named after the apical meristem, the plant cells undergo rapid mitotic division, creating new cells for root growth.
What root hair means?
n. The part of a hair that is embedded in a hair follicle.
What is antibody structure?
An antibody has a Y-shaped structure, made up of four polypeptide subunits. Each subunit has two identical light and heavy chains. The N-terminus of each heavy chain forms an antigen-binding domain with a light chain. There are two antigen-binding domains forming the arms of the “Y” shape.
How many cells are in root hair?
Because the Arabidopsis primary root always possesses eight files of cortical cells, there are eight root-hair cell files and approximately 10 to 14 non-hair cell files (Dolan et al., 1994; Galway et al., 1994).
Are root hairs multicellular?
Difference between Root Hair and Stem Hair
| Root Hair | Stem Hair |
|---|---|
| It is a unicellular structure. | It is a multicellular structure. |
| Structure | |
| It is an elongation that arises from the epidermis of the root cells. | It is an outgrowth of the epidermis formed by division of the epidermal cells. |
| Cutinization |
What are the 5 antibodies?
5 types of antibodies, each with a different function There are 5 types of heavy chain constant regions in antibodies (immunoglobulin) and according to these types, they are classified into IgG, IgM, IgA, IgD, and IgE. They are distributed and function differently in the body.
