Function of Cytoplasm in Bacterial cell

Concentrated deposits of certain substances which are presented/located in the cytoplasm of certain bacteria are known as cytoplasmic granules or inclusion bodies.They serves as storage areas for nutrients, e.g. volutin granules are reserve of high energy stored in the form of polymerized metaphosphate. The number and nature of the inclusions vary depending on…

Part I: The critical role of spatial organization in bacterial cell function Lecture Overview Most bacterial cells are many, many times smaller than eukaryotic cells. Since they have no membrane-bound internal organelles, their cellular organization also appears much simpler. Over the last decade, however, scientists have come to understand that that bacterial…

Cell membrane Function in Bacteria

Mechanical Structure (a) Defines / encloses the Cell A cell membrane encloses and defines the cell. There are different ways to express this, e.g. The cell membrane maintains the physical integrity of the cell. It s most obvious in the cases of animal cells (because they don t have cell walls) that the cell membrane holds the cell together by enclosing the cytoplasm…

Function of Cytoplasm in Human cells

All living organisms on earth consists of cells which are the basic units of life. Based on their function, cells are categorized into different types of cells, the somatic cells and the reproductive cells. Each cell has a nucleus and a jellylike watery substance that is 80% water that occupies the remaining part of the cell. This is called Cytoplasm. The cytoplasm…

Human cell Functions and Parts

I remember being in Mr. Farnsworth’s 7th grade science class when we first really began learning about cells. His room looked like the typical high school lab—high, hard tables with Bunsen burners and gas jets that no one was allowed to touch, and a cabinet full of dead things suspended in fluid in jars. My favorite thing about the room was the giant poster of…

Function of Ribosome in Bacterial cells

Ribosomes are small particles, present in large numbers in all the living cells. They are sites of protein synthesis. The ribosome word is derived - ribo from ribonucleic acid and somes from the Greek word soma which means body . The ribosomes link amino acids together in the order that is specified by the messenger RNA molecules. The ribosomes are made…

Prokaryotic cells Parts and Functions

Prokaryotic cells are simpler and smaller than the eukaryotic cells. The term prokaryote is derived from the Greek word- “prokaryote” meaning before nuclei. These cells lack membrane bound organelles. Prokaryotic cells are unicellular organisms, which reproduce through binary fission. In some cases few prokaryotic organisms also reproduce by budding. Prokaryotic…

Functions of soil organic matter

Effect on soil physical condition, soil erosion and soil buffering and exchange capacity Humus has a profound effect on the structure of many soils. The deterioration of structure that accompanies intensive tillage is usually less severe in soils adequately supplied with humus. When humus is lost, soils tend to become hard, compact and cloddy. Aeration, water-holding…

Parts of Prokaryotic cells and their Functions

Prokaryotic cells are one of the most basic kinds of cells that are out there in Biology. They are the cells of bacteria, so let s take a look at what makes up the key characteristics of a prokaryote. Now their name tells you one of their most important things; pro means before kary means nucleus, so this tells you that this is what cells that evolved before…

The Golgi Apparatus Model. David Gunn / Getty Images The following are examples of structures and organelles that can be found in typical plant cells: Chloroplast - the sites of photosynthesis in a plant cell. They contain chlorophyll, a green pigment that absorbs energy from sunlight. Endoplasmic Reticulum (ER) - extensive network of membranes composed of both…

Function of pili in Bacterial cell

Found mainly in Gram negative organisms, Fimbriae or pili ( singlular: pilus ) are hair like filaments (tiny hollow projections) that extend from the cell membrane into the external environment. A pilus is composed of subunits of the protein pilin. Bacteria use adherence fimbriae (pili) to overcome the body’s defense mechanism and cause disease. Pili are small…

Plasma membrane- The membrane enclosing a cell is made up of two lipid layers called a bilipid membrane. The lipids that are present in the plasma membrane are called phospholipids. These lipid layers are made up of a number of fatty acid building blocks. The fatty acid that makes up this membrane has two different parts to it- a small water loving head…

Functions of Parts of the cell

All living things are made up of cells. The structures of different types of cells are related to their functions. Animal cells and plant cells have features in common, such as a nucleus, cytoplasm, cell membrane, mitochondria and ribosomes. Plant and algal cells also have a cell wall, and often have chloroplasts and a permanent vacuole. Bacterial and yeast cells…

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 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…
