The Chemistry of Life 3.1 Chemical Elements and Water 3.1.1 State that the most frequently occurring chemical elements in living things are carbon‚ hydrogen‚ oxygen and nitrogen. Carbon‚ hydrogen‚ oxygen and nitrogen are the most frequently occurring chemical elements in living things. 3.1.2 State that a variety of other elements are needed by living organisms‚ including sulphur‚ calcium‚ phosphorus‚ iron and sodium. Other elements are needed by living organisms including sulphur‚ calcium

which are organisms without a nucleus and a single chromosome (a double-stranded DNA located in an area of the cell) instead. In the lab‚ organism one is a very small dark green leaf from a small plant. Under the microscope‚ there is a lot of chlorophyll‚ floating around inside the rectangular cells. Organism one

Class IX: Biology Chapter 5: The fundamental unit of life. Chapter Notes Key learnings: 1) In 1665‚ Robert Hooke first discovered and named the cells. 2) Cell is the structural and functional unit of all living organisms. 3) Organisms may be unicellular or multicellular. A single cell constitutes the unicellular organism whereas many cells coordinately function in case of multicellular organism. 4) The size‚ shape and volume of the cell are related to the specific function that they

Prokaryotic cells are single celled organisms that were formed at the formation of the earth‚ so are the most basic life forms. The prokaryotes are organised in the ‘three domain system’ and include bacteria and blue-green algae. Prokaryotes live in many environments including extreme habitats such as hydrothermal vents‚ hot springs‚ swamps‚ wetlands‚ and the guts of animals. This is a diagram of a prokaryote cell and it shows that they are not very complex cells. They do not contain any membrane

One of the most essential and proven methods to lose weight is to reduce caloric intake. Consuming fatty foods each day will not help you to meet your weight loss goals. Instead‚ focus on eating foods that are not only healthy but will help you to maintain your ideal weight. What are they? Raw‚ nutritional foods are more beneficial for the health of the body because they contain a high level of nutrients that are easily assimilated once consumed. Healthy Foods to Eat For Weight Loss When you are

during cellular respiration‚ these sugars are converted into ATP. ATP is the fuel that is used by all living organisms. The conversion of the unused sunlight energy into usable chemical energy is associated with the actions of the green pigment chlorophyll. In this process‚ water is used and oxygen is released that we absolutely need to stay alive. we can write the over all reaction of this process as: 6 Water molecule’s + 6 CO2 molecule’s + light → 1 Glucose molecule + 6 oxygen molecule’s How

One aspect of nutrition that is vital is protein. Protein is one of four major building materials in the human body. Proteins are composed of carbon with Hydrogen‚ Oxygen‚ and Nitrogen attached. Some proteins also have Sulfur‚ Phosphorus‚ and Iron. Proteins are made up of sub-units called amino acids‚ of which there are twenty. These are just the basics of what proteins are composed of. Amino acids‚ which are the sub-units of Proteins‚ can be divided into two groups. Eleven of the twenty amino
