Sentences with phrase «root hair cells»

Firstly water is absorbed by the root and moves through root hair cells via the process of osmosis (we will look at this another day!).

«This suggested that the negatively charged indole acetic acid hormone molecule is absorbed into the root hair cell together with an excess amount of positive ions,» Hedrich says.

To define the proteomic response of the soybean root hair cell to variations in temperature and water availability, the researchers will use mass spectrometers housed at EMSL, a DOE scientific user facility located at PNNL.

By micro-injecting IAA directly into the root hair, Julian Dindas also demonstrated that an auxin - treated cell does more than send a calcium signal.

Julian Dindas, a PhD student at Hedrich's department, used microelectrodes that register the electric voltage of the root hair's cell membrane, the so - called membrane potential, to study the early responses of the cell to a hormone pulse.

«Skin cells found at root of balding, gray hair.»

Within a hair follicle, there are stem cells that reside in an area called the hair follicle «bulge,» which is a small compartment located where the outer root sheath meets the arrector pili muscle (see Hair Follicle figuhair follicle, there are stem cells that reside in an area called the hair follicle «bulge,» which is a small compartment located where the outer root sheath meets the arrector pili muscle (see Hair Follicle figuhair follicle «bulge,» which is a small compartment located where the outer root sheath meets the arrector pili muscle (see Hair Follicle figuHair Follicle figure).

To confirm, evaluate, and quantify the extent of such exponential behavior in individual plant roots, we analyzed root epidermal (trichoblast, to be able to recognize root hair) and cortex cell files of wild ‐ type Col ‐ 0 ecotype, from day 1 to 10 postgermination (Materials and Methods, Dataset EV1).

Morphologically, the DZ in the wild type (WT) is marked by the appearance of epidermal root hairs on the external surface of outer cell files (trichoblast) and the existence of fully differentiated xylem for internal cell files (Dolan et al, 1993; Ishikawa & Evans, 1995; Beemster et al, 2003; Verbelen et al, 2006; Zhang et al, 2010; Mähönen et al, 2014).

The cells are held close to the base of the epidermal derived cells that produce the hair fiber and root sheaths but there is a thin layer, called the basement membrane (or basement lamina, or glassy membrane) that separates the DP cells from the hair fiber / sheath cells.

The cells then clump together on your scalp and form flakes which become dislodged and hang around at the roots of your hair.

The four main stages of the hair cycle are: anagen (characterized by rapid growth and proliferation), catagen (a period of cell apoptosis), telogen (a resting period) and exogen (hair loss from the root)[9].
