Plant cells Chromosomes Function

Chromosomes are the thread-like structure found in the nuclei of both animal and plant cells. They are made of protein and one molecule of deoxyribonucleic acid (DNA). As the genetic material passes from parents to child, the chromosomes are responsible for containing the instructions that make the offspring unique while still carrying traits from the parent…

Bacterial Infections

Coughing and sneezing. Contact with infected people, especially through kissing and sex. Contact with contaminated surfaces, food, and water. Contact with infected creatures, including pets, livestock, and insects such as fleas and ticks. Microbes can also cause: Acute infections, which are short-lived. Chronic infections, which can last for weeks, months, or…

Cell flagella Function

Centrioles function as the major micro tubule organizing centers which is an important event in two major cellular processes - cell division and cilia and/or flagella formation. Given below is a description of the precise role of centrioles in each of these processes. Cell Division The pair of centrioles within a cell duplicates, and the two pairs migrate to…

Capsule Function in Prokaryotic cell

A prokaryote is a simple, unicellular organism that lacks an organized nucleus or other membrane-bound organelle. Learning Objective Describe the structure of prokaryotic cells Key Points Prokaryotes lack an organized nucleus and other membrane-bound organelles. Prokaryotic DNA is found in a central part of the cell called the nucleoid. The cell wall of a prokaryote…

Bacterial cells Function

Bacteria cells function quite differently from human cells, from the function of the cell as a whole, right down to the individual structures in each cell. Bacteria exist in nature as individual cells. While some bacteria work together in a group, no bacteria forms multicellular tissues. Bacteria have organized structures within the cell, but do not have membrane-bound…

Parts and Functions of a Prokaryotic cell

Prokaryotic cells fall into a size range of about 1–5Вµm and hence can be observed clearly by microscopes. However, some prokaryotic cells may be larger than this. A prokaryotic cell contains external and internal structures. Capsule, flagella, axial filaments, fimbriae, and pili are present external to the cellwall, while interior of the bacterial cell contains…

Flagella Function in Animal cells

Cilia and flagella are motile cellular appendages found in most microorganisms and animals, but not in higher plants. In multicellular organisms, cilia function to move a cell or group of cells or to help transport fluid or materials past them. The respiratory tract in humans is lined with cilia that keep inhaled dust, smog, and potentially harmful microorganisms…

Functions of Pili in Bacteria

This is clearly beneficial to the F-plasmid, since its genes get replicated, but why is it useful to the bacteria? The F-plasmid often contains useful genes that deal with stressful situations that have recently arisen, for will spread this resistance to other bacteria. Since the F-plasmid can integrate into the host s chromosomal DNA it can, upon leaving, take…

Bacterial cell Parts and Functions

The bacterial cell surface (or envelope) can vary considerably in its structure, and it plays a central role in the properties and capabilities of the cell. The one feature present in all cells is the cytoplasmic , which separates the inside of the cell from its external environment, regulates the flow of nutrients, maintains the proper intracellular milieu…

Cell Component and their Functions

The cell body (soma) is the factory of the neuron. It produces all the proteins for the dendrites, axons and synaptic terminals and contains specialized organelles such as the mitochondria, Golgi apparatus, endoplasmic reticulum, secretory granules, ribosomes and polysomes to provide energy and make the parts, as well as a production line to assemble the parts…

Summary: A new study reaffirms the link between intestinal bacteria and altered gut and brain function. Source: McMaster University. Finding may lead to new microbiota-directed therapies for gastrointestinal upset and brain disorders. Research from McMaster University has found that bacteria in the gut impacts both intestinal and behavioural symptoms in patients…

Bacterial cell wall Function

There are different types of cells, including animal cells, plant cells, fungal cells and bacteria cells. They vary in structure, depending on the type of cell and its function. Cell walls can be flexible, like those in plant cells, or rigid, like those in bacterial cells. The main job of the cell wall is to prevent the cell from over-expanding when water enters…

Function of Bacterial plasmid

A plasmid is a small, circular, double-stranded DNA molecule that is distinct from a cell s chromosomal DNA. Plasmids naturally exist in bacterial cells, and they also occur in some eukaryotes. Often, the genes carried in plasmids provide bacteria with genetic advantages, such as antibiotic resistance. Plasmids have a wide range of lengths, from roughly one thousand…

The crystal structure of the membrane-integrated nitric oxide reductase cNOR from Pseudomonas aeruginosa was determined. The smaller NorC subunit of cNOR is comprised of 1 trans-membrane helix and a hydrophilic domain, where the heme is located, while the larger NorB subunit consists of 12 trans-membrane helices, which contain heme b and the catalytically active…

Major Functions of Cytoplasm

Cytoplasm, a jelly like substance (called cytosol or cytoplasmic matrix or hyaloplasm) and composed of mainly water is found between the cell membrane and nucleus. It contains the structures and substances needed to decode the instruction of DNA and carry on the activates of the cell. Cytoplasmic structures comprises three groups: organelles, cytoplasmic inclusions…

Function of pili in Prokaryotic cell

Cell wall: Protects the cell from the outside environment and maintains the shape of the cell. It also prevents the cell from bursting if internal pressure rises. Plasma membrane : Semi-permeable membrane that controls the substances moving into and out of the cell. It contains integral and peripheral proteins. Substances pass through by either active or passive…

Bacterial cells Organelles and their Functions

There is compelling evidence that mitochondria and chloroplasts were once primitive bacterial cells. This evidence is described in the endosymbiotic theory. How did this theory get its name? Symbiosis occurs when two different species benefit from living and working together. When one organism actually lives inside the other it s called endosymbiosis. The endosymbiotic…

Cell Functions and Parts

The nucleus is where the DNA is kept and RNA is transcribed. RNA is moved out of the nucleus through the nuclear pores. Proteins needed inside the nucleus are transported in through the nuclear pores. The nucleolus is usually visible as a dark spot in the nucleus, and is the location of ribosome formation. Ribosomes are where RNA is translated into protein. This…

All living things are made up of a cell or cells, and all cells are either prokaryotic or eukaryotic. A eukaryotic cell is a complex cell with a nucleus and many organelles. Eukaryotic cells are the building blocks of all animals, plants and fungi. Prokaryotic cells are very simple cells with fewer structures than eukaryotic cells; one primary difference is that…
