Worksheet 2- Brittani Wright 1. a) Define a cell. A cell is the basic unit of life b) What is a unicellular organism? An organism that consists of only one cell c) Can a cell be multicellular? No because a cell is the smallest unit of life‚ cells can however join together to start forming something else 2. a) What is a difference between prokaryotic and eukaryotic cells? b) What is one significant similarity? Prokaryotic cells do not have a neucleus and Eukaryotic cells do have a nucleus

NATIONAL CENTER FOR CASE STUDY TEACHING IN SCIENCE The Mystery of the Seven Deaths: A Case Study in Cellular Respiration by Michaela A. Gazdik Biology Department Ferrum College‚ Ferrum VA Part I – The Symptoms Imagine that you work at the medical examiner’s office for a major metropolitan city. As Chief Medical Officer‚ you investigate suspicious deaths and provide toxicology services for the county. Unfortunately‚ it’s been a busy week. In the past five days‚ seven people have died‚ all with similar

plants transform radiant solar energy into chemical energy that gets stored as potential energy in carbohydrates‚ and conduction of nerve impulses which is when chemical energy is transformed into electrical energy. An example of energy transfer is; respiration when the chemical energy stored in respiratory substrates is transferred to ADP and is stored in ATP. The ATP molecules transfer energy to other biological molecules. ATP‚ which stands for adenosine tri-phosphate‚ is an energy rich compound having

the rate of aerobic cellular respiration in aquatic organisms which are Elodea (aquatic plant)‚ Snail‚ and Goldfish‚ by measuring carbon dioxide production. Because ectothermic organisms (Elodea‚ snail‚ and goldfish) were placed in completely covered beaker‚ each organism would produce different amount of carbon dioxide. The objective of the experiment is to measure carbon dioxide production in three aquatic organisms‚ and to determine and compare the rate of cellular respiration in each organism.

A cyclist rides her bike up a very steep hill. Which choice below properly describes this example in energetic terms? Both a) and d) are correct. Every time a source of energy is converted from one form to another: some of the energy is converted to heat‚ which is not a very usable form of kinetic energy. A green plant will grow if given nothing more than: water‚ light‚ and carbon dioxide The leaves of plants can be thought of as "eating" sunlight. From an energetic perspective this makes

rely on their seeds and pollen or spores for reproduction. Plants use photosynthesis and cellular respiration. “Photosynthesis is the process used by plants‚ algae and certain bacteria to harness energy from sunlight into chemical energy‚” said by Science Live. Photosynthesis uses carbon dioxide and creates oxygen. Living creatures including plants get their energy from cellular respiration. Cellular respiration changes oxygen and glucose to carbon dioxide and water into energy. Plant cells work just

Energy is essential for making new cells to enable growth‚ repair‚ and development to ensure the proper functioning of the body. Energy can be obtained from the food we eat (mainly from carbohydrates and fats) a process called respiration. Respiration is the chemical process whereby energy is obtained from the body of a living organism with or without the use of oxygen. Energy is also essential in the body to enable breathing and take in oxygen. Carbohydrates are broken down into glucose
