task 1 – INTRODUCTION INSTRUCTIONS: Please provide a flow diagram with commentary (including specific examples) on the organisation of the human body. You must include cells, tissues, body organs and systems. Any images used must be sourced. The human body is extremely complex and contains different systems which work alongside each other but complete diverse tasks to keep our body’s functioning. Chemical level– is the simplest level within the structural hierarchy. The chemical level

ymbiosis – What is it? The term symbiosis relates to close interactions between different biological organisms and the interdependent relationships between living things, in which completely different forms of life depend upon each other for existence. One example of beneficial symbiosis (or mutualism) is found between algae and the fungus of lichens. While fungi provide vital protection and moisture to algae, the algae nourish the fungi with photosynthetic nutrients that keep them alive. Another

The cell is the basic functional in a human meaning that it is a self-contained and fully operational living entity. Humans are multicellular organisms with various different types of cells that work together to sustain life. Other non-cellular components in the body include water, macronutrients (carbohydrates, proteins, lipids), micronutrients (vitamins, minerals) and electrolytes. A collection of cells that function together to perform the same activity is known as tissue. Masses of tissue work

of organisms whose cells lack a membrane bound nucleus. They are unicellular organisms, although a few such as myxobacteria have multicellular stages in their life cycles or create large colonies like cyanobacteria. Prokaryotes do not have a membrane bound nucleus, mitochondria,or any other membrane bound organelles. In other words, all their intracellular water soluble components(proteins, DNA, and metabolites) are located together in the same volume enclosed by the cell membrane, rather than

Travel Brochure of a Cell Create a travel brochure that describes an animal or plant cell as if it were a museum or amusement park. Your brochure must attract visitors to spend money to visit a plant or animal cell. You can think of it as a huge amusement park or a small roadside attraction. Your attractions will “delight and amaze” your potential visitors. You must accurately DRAW, DESCRIBE and EXPLAIN THE FUNCTION of the required organelles (marked with *). Required organelles are

signal sequence from its primary amino acid sequence. Devise an approach that can be used to ascertain the mechanism of IL-1 secretion. Overview • Eukaryotic cells are structurally and functionally compartmentalized. • This provides a favorable chemical environment for specialized reactions to take place in a large cell. • Specialization is provided by proteins that are sorted (localized) to these compartments. Signal sequences for secretion Organelles are specific for

major components of cell theory. Q1. All organisms are made up of cells. When we observe organisms, we are seeing a collection of cells work together in a highly organized and regulated manner to create life; also old cells are the building blocks for new cells to copy. Q2. Evaluate why a cell and a whole organism are both examples of biological systems. A cell and a whole organism are both examples of biological systems because Organisms are composed of cells; both cells and organisms are

How We Study Cells Describe the principles, advantages, and limitations of the light microscope, transmission electron microscope, and scanning electron microscope. Electron microscopes reveal organelles that are impossible to resolve with the light microscope. However, electron microscopes can only be used on dead cells. •Light microscopes do not have as high a resolution, but they can be used to study live cells. •Transmission electron microscopes (TEMs) are used mainly to study the internal
