Biology is a natural science concerned with the study of life and living organisms‚ including their structure‚ function‚ growth‚ evolution‚ distribution‚ and taxonomy.[1] Modern biology is a vast and eclectic field‚ composed of many branches and subdisciplines. However‚ despite the broad scope of biology‚ there are certain general and unifying concepts within it that govern all study and research‚ consolidating it into single‚ coherent field. In general‚ biology recognizes the cell as the basic unit

development research | 1.) Tiny Genome- Therefore it is easy to study the genes and also to manipulate the genes.2.) Short Life Cycle- Experiments conducted on the A.thaliana will have observable results fast as the development of the plant is rapid.3.) Small size-can be cultivated in a tiny space and this is vital because research areas usually have space limitations.4.) Male and female sex organs available on the same flower- vital for plant genetic mating research | 1.) Pests- Pests are easily

Learning about Cells. First thing I want to show you is two beautiful pictures of a Cell. Imagine all of this is in something so small we cannot see it with our naked eyes. About 10‚000 average-sized human cells can fit on the head of a pin. There are a few exceptions‚ but the average cell is very tiny. Here are a few beautiful examples of a cell structure to kind of give you an idea of its beauty‚ and how they fit together. Plasma Membrane (cell membrane) First we are going to learn about

Page 1 of 8 BIOLOGY 12- CELL STRUCTURE & FUNCTION Chapter Notes THE CELL THEORY • Although different living things may be as unlike as a violet and an octopus‚ they are all built in essentially the same way. The most basic similarity is that all living things are composed of one or more cells. This is known as the Cell Theory. • our knowledge of cells is built on work done with microscopes • English scientist Robert Hooke in 1665 first described cells from his observations of cork slices

Human Biology Unit 1 Assignment. A cell is a small membrane enclosed structure filled with an aqueous solution where the organelles are found. Organelles are small structures within cells that perform dedicated functions. All eukaryotic cells have the following organelles: Nucleus‚ Ribosomes‚ Lysosomes‚ Cytoplasm‚ Nucleolus‚ Cell Membrane‚ Mitochondria‚ Endoplasmic Reticulum (ER) and Golgi Body. Insulin is a protein compound made up of more than one chain of amino acids. Amino acids are the building

between the structure and function of four specialised human cells. The human body is made up of trillions of different cells; all play a huge role in the running and function of the body. They are the foundation of all living things. Each different cell has its own exclusive job. Without cells the human body would simply fail. All cells contain organelles which are the structures of the cells itself‚ organelles have individual functions. This essay will investigate the structure and function of four

Prokaryotic – no organelles; no nucleus; bacteria and Achaea; spherical‚ rodlike/corkscrew-shaped; cell wall; Eukaryotic – has nucleus; has organelles Commonalities – contain DNA that stores genetic information What is the main component of cellular membranes? What function(s) do membranes serve in cells? Made of phospholipids; defines
