Organelles
1. all living organisms are made up of cells
2. cells are the basic structural unit of all organisms that perform life functions
3. all cells come from pre-existing cells
Identify the name of the type of cell found in multicellular organisms
Eukaryotic cells
Describe the function of the respiratory system
To diffuse and exchange gases such as oxygen and carbon dioxide into the bloodstream
Describe the function of the circulatory system
The function is to transport oxygen, carbon dioxide, nutrients and wastes around the body to cells
Describe the function of the red blood cells
To carry oxygen and carbon dioxide around the body
The nucleus is an organelle that houses what?
Describe the structure and function of the cell membrane
The cell membrane is a thin outer layer of a cell that allows for nutrients and waste to pass in and out of the cell
Identify the components in the circulatory system
Heart, Blood and blood vessels (arteries, veins and capillaries)
Identify the names of the four chambers in the heart
Right atrium, Right ventricle, Left atrium, Left ventricle
Describe the structure of a nerve cell and their function (what they do)
Nerve cells are long and carry electrical messages
This is the organelle that is responsible for producing ATP (Energy) in a cell
Mitochondria
The mitochondria is also known as the.....
powerhouse of the cell
It has a large surface area with a lot of blood supply from capillaries in order to diffuse gases quickly in and out of the bloodstream.
Describe the function of the digestive system
To break down food chemically and mechanically into smaller pieces to be absorbed by the body
Identify the three types of muscle cells
1. Cardiac muscles,
2. skeletal muscles,
3. smooth muscle
Identify the colour of a chloroplast and describe their function
Chloroplasts are green in colour and allow the production of a cells own energy using the sun and photosynthesis
Describe the cell wall's structure and function and identify the type of cell they are only found in
They are only found in plant cells and provide the cell more structure and greater protection from movement in and out of a cell
Describe the role of the white blood cells in the body
To act as part of the immune system that defend the body against pathogens like viruses, parasites and bacteria
In a cell the vacuole is responsible for
Storing waste, nutrients and water
Describe the differences between a vacuole in a plant cell vs an animal cell
Describe the impact of an intestinal issue on the villi's structure and function
An intestinal issue would cause the villi to be shortened and would result in reduced surface area. With a lower surface area, poorer nutrient absorption happens in the intestines.
Describe the impacts of vaping on the airways
Vaping causes inflammation and scarring on the lungs which leads to reduced surface area, reduced diffusion and lower blood oxygen levels.
Identify the name of the specialised cells that line the airways and have tiny hair-like structures call cilia that move mucus and dirt away from the lungs
Ciliated Epithelial Cells
