Biology Quiz for Year 8

cellular respiration

• process that releases energy by breaking down glucose and other food molecules in the presence of oxygen

• an organelle found in plant and algae cells where photosynthesis occurs

• organelle where cellular respiration occurs in both plants and animals (makes ATP)

• a living thing

chloroplast

• fats

• nutrients that are made up of long chains of amino acid

• an organelle found in plant and algae cells where photosynthesis occurs

• a nutrient in food that gets broken down into glucose to provide energy

mitochondria

• organelle where cellular respiration occurs in both plants and animals (makes ATP)

• a unit used to measure the amount of energy contained in foods

• the human body system that contians the heart, blood, and all of the blood vessels. It delivers all the nutrients to the cells

• exchange of gases (oxygen and carbon dioxide) at the lung capillaries (external respiration) and at the tissue capillaries (internal respiration)

organism

• the process by which plants use the sun's energy to convert water and carbon dioxide into sugars;oxygen and water are released

• the human body system that contians the heart, blood, and all of the blood vessels. It delivers all the nutrients to the cells

• a nutrient in food that gets broken down into glucose to provide energy

• a living thing

proteins

• a unit used to measure the amount of energy contained in foods

• building blocks of life

metabolism

• condition that results from having narrow or blocked blood vessels that can lead to a heart attack

• condition where the body produces too little or no insulin or where insulin produced cannot be used normally by the body

• A form of potential energy that is stored in chemical bonds between atoms.

• all of the chemical reactions that occur within an organism

circulatory system

• all of the chemical reactions that occur within an organism

• exchange of gases (oxygen and carbon dioxide) at the lung capillaries (external respiration) and at the tissue capillaries (internal respiration
