Gut microbiota - Wikipedia

Gut microbiota, gut flora, or microbiome are the microorganisms including bacteria, archaea and fungi that live in the digestive tracts of humans and other animals including insects.The gastrointestinal metagenome is the aggregate of all the genomes of gut microbiota. The gut is the main location of human microbiota.

Cell (biology) - Wikipedia

The cell (from Latin cella, meaning "small room") is the basic structural, functional, and biological unit of all known organisms.Cells are the smallest units of life, and hence are often referred to as the "building blocks of life". The study of cells is called cell biology, cellular biology, or cytology.. Cells consist of cytoplasm enclosed within a membrane, which contains many biomolecules ...

Apr 05, 2021· T cell-selective coating and protection strategy with a flexible DNA network promotes T-cell aggregation and activation for anti-tumor therapy. (A) T cell selective protection strategy by constructing a flexible DNA network on T cell surface using in situ RCA reaction and a T cell-targeted trivalent TDN scaffold. (B) Schematic diagram of T cell ...

Eukaryote - Wikipedia

Eukaryotic cells are typically much larger than those of prokaryotes, having a volume of around 10,000 times greater than the prokaryotic cell. They have a variety of internal membrane-bound structures, called organelles, and a cytoskeleton composed of microtubules, microfilaments, and intermediate filaments, which play an important role in defining the cell''s organization and shape.

Lipids - Chemistry

2. Soaps and Detergents. Carboxylic acids and salts having alkyl chains longer than eight carbons exhibit unusual behavior in water due to the presence of both hydrophilic (CO 2) and hydrophobic (alkyl) regions in the same molecule ch molecules are termed amphiphilic (Gk. amphi = both) or amphipathic. Fatty acids made up of ten or more carbon atoms are nearly insoluble in water, and because ...

Internal Structure of Stem (With Diagram)

ADVERTISEMENTS: The below mentioned article provides an outline of internal structure of stem of both dicotyledons and monocotyledons type. The embryo develops into a plant with root-stem axis and the appendages. In fact, three important organs of a plant are the stem, the leaves and the root. The continuity of the tissues, and particularly the […]

Signals stimulate cell multiplication of both the plant cells and the bacteria. This repeated division results in a mass of root cells containing many bacterial cells. Some of these bacteria then change into a form that is able to convert gaseous N into ammonium nitrogen (they can "fix" N).

Top 4 Historical Models of Plasma Membrane | Cell | Biology

ADVERTISEMENTS: The following points highlight the top four historical models of Plasma Membrane. The models are: 1. Lipid and Lipid Bilayer Models 2. Unit Membrane Model (Protein-Lipid Bilayer-Protein) 3. Fluid Mosaic Model 4. Dannelli Model. 1. Lipid and Lipid Bilayer Model: This model to explain the structure of plasma membrane was given by Overton, Gorion […]

sources. Natural colors are obtained from mineral, plant and animal sources. Mineral colors (also called as pigments) are used to color lotions, cosmetics, and other external preparations. Plant colors are most widely used for oral suspension. The synthetic dyes should be used within range of 0.0005 % to 0.001

Modifications of Stem (Explained with Diagram)

ADVERTISEMENTS: Some of the most important types of modifications of stem are as follows: I. Underground modifications of Stem II. Subaerial modifications of Stem III. Aerial modifications of Stem. I. Underground modifications of Stem: ADVERTISEMENTS: Many plants produce underground stems for perennation and food storage. They produce aerial shoots annually. Although they resemble roots ...

What Do All the Parts of a Cell Do? | Sciencing

Aug 31, 2018· The cell membrane, also called the plasma membrane, is a physical boundary between the cell''s internal environment and the outside world. Do not, however, mistake this basic assessment for the suggestion that the cell membrane''s role is merely protective, or that the membrane is merely some kind of arbitrary property line.

Auxin accumulates on the downwards-facing side of the stems and the roots. In the shoots, the increased auxin promotes greater cell-elongation, causing the tip of the stem to bend upwards. In the roots, the increased auxin inhibits cell-elongation, causing the tip of the root to bend downwards.
