Living Systems
Vocabulary -- Investigation 1
Living Cells
Part 1
• cell – basic unit of life
• oxygen – atmospheric gas needed by most living things
• carbon dioxide – waste gas produced by living cells
• heart – muscular organ that contracts rhythmically, producing a pulse with each contraction
• blood – liquid tissue that flows to and from cells
• pulse – produced with each contraction of the heart
• blood vessel – blood flows to and from cells in blood vessels
• capillary – smallest blood vessel; gases, nutrients, and wastes are exchanged between capillaries and cells; capillaries carry blood rich with oxygen, food, and other nutrients to every cell and carry all waste materials away
• artery – blood vessel that carries blood away from the heart to the body
• vein – blood vessel that carries blood back to the heart
• circulatory system – includes tissues (blood and blood vessels) and organs (heart) that transport life-support substances to cells and removes waste.
• right atrium – one of the 4 chambers of the heart
• right ventricle – one of the 4 chambers of the heart
• left atrium – one of the 4 chambers of the heart
• left ventricle – one of the 4 chambers of the heart
• tissue – a group of cells of the same kind, working together to perform a function. In the circulatory system: blood and blood vessels (types of tissues include muscle tissue, bone tissue, nerve tissue)
• respiratory system – includes tissues and organs (lungs) that provide gas exchange between the blood and atmosphere
• lung – organ of the respiratory system. Organ in animals where gases, such as oxygen and carbon dioxide pass between the atmosphere and the blood
Part 2
• digestive system – system of organs and structures responsible for the digestion of food. the digestive system includes the teeth, mouth, esophagus, stomach, small intestine, large intestine, and colon.
• digestion – process of breaking down food into nutrients that can be used by cells
• mouth and teeth – where food is taken in and what is used to moisten (by saliva), chew and bite, and cut it; first step in the digestion process
• esophagus – tube connecting the mouth and the stomach
• stomach – organ where food is reduced to mush by acid and muscle activity
• small intestine – part of the digestive system between the stomach and large intestine that absorbs nutrients from digested food.
• large intestine – part of the digestive system between the small intestine and the rectum where water is removed from the solid waste
• colon – large intestine where solid waste is compacted and dehydrated in preparation for elimination
• waste – what the body does not use
• kidney – an organ that filters and cleans the blood
• urine – liquid waste produced by the kidneys
• bladder – organ that holds urine until it is eliminated
• excretory system – the system which includes the kidneys, and bladder, that eliminates waste
• cellular waste – chemical produced by cells that must be removed
Part 3
• The respiratory system moves gases between the atmosphere and the blood
• The circulatory system carries resources and wastes to and from the cells
• The digestive system breaks food into sugar and other chemicals that can be used by cells
• The excretory system filters the blood and carries cellular waste materials out of the body
Vocabulary -- Investigation 2
Vascular Plants
Part 1
• cross section – cuts across an object and exposes its internal structure
• vascular plants – a multicellular plant that has vessels for transporting water, minerals, and sugar to all the cells.
• xylem- vascular plants have these tubes to transport water
• phloem- these tubes transport sugar to the plant cells
• sap- the sugar rich liquid that flows from the phloem
Part 2
• classify – putting things in groups based on similar properties or behaviors.
• palmate- Several large veins extending from the place where the leaf stem attaches to the leaf. Think of the palm of your hand and your fingers as the main veins.
• pinnate- One large vein extending the length of the leaf with smaller leaves branching off. Pinna means feather so a pinnate leaf resembles a feather in a way.
• parallel- Many small veins running the length of the leaf. Long, narrow leaves, like blades of grass, tend to have parallel veins.
Vocabulary -- Investigation 3
Sugar and Cells
Part 1
• food – the source of energy and building materials for living cells
• photosynthesis – is a chemical process in which cells produce energy-rich sugar molecules and release oxygen
• fat – a group of nutrients that provides energy and building blocks for growth and development
• protein – a group of nutrients that provides energy and building blocks for growth and development
• mass – a quantity of matter
• sunlight – light from the sun or solar energy
• starches – chemicals produced by plants to store food
• molecule – a particle made of two or more atoms. A sugar molecule is made of carbon, hydrogen, and oxygen atoms.
Part 2
• yeast – single celled organism
• cellular respiration – process by which plant and animal cells break down sugar to get energy, releasing carbon dioxide in the process.
Part 3
• chlorophyll – a molecule that absorbs light energy.
• photosynthesis – process by which green plants make sugar from carbon dioxide and water in the presence of light.
• sunlight – light from the sun
• glucose – the sugar made during photosynthesis
• cellular respiration – the process by which plants and animals break down sugar molecules for energy
