Chemistry of Life

This is the most important element in the human body. It is found in water and in the lungs and blood due to respiration. oxygen
This element is found in every organic molecule in the body. It is also found in the waste product in respiration. carbon
This is the element found in water molecules. It is also found in many compounds found in various types of tissue. hydrogen
This element is very common in proteins and organic compounds.. It is also found in nucleic acids, RNA and DNA. nitrogen
This element is needed for strong teeth and other bones in the skeletal system. calcium
This element is found in blood. It helps to transport oxygen. Iron
This theory states that all living things are made of one or more cells, the cell is the smallest unit of life, and all new cells come from preexisting cells. cell theory
A membrane-surrounded component of a cell that has specialized functions. organelle
The part of an eukaryotic cell that directs cell activities andcontains genetic information found in DNA. nucleus
A network of threadlike proteins that are joined together. cytoskeleton
A fluid inside a cell that contains salts and other molecules where chemical reactions take place to provide energy for the cell. cytoplasm
A stiff structure outside the cell membrane found in plant, bacterial, fungal, and some protist cells. cell wall
A flexible covering that protects the inside of a cell from the environment outside the cell. cell membrane
A membrane-bound organelle that uses light energy and make food, glucose, from water and carbon dioxide in a process called photosynthesis. chloroplast
This cell has genetic information surrounded by a membrane. Animal, plant, fungi, and protist cells are all examples. The cell is separated from the outside environment by a cell membrane. eukaryote cell
This cell does not contain a nucleus. Many of these organisms are unicellular organisms. prokaryote cell
helps to digest food or to break down worn or dead cell parts; built in the Golgi bodies lysosome
protein synthesizers of the cell; help to make protein ribosome
the whip-like tail that allow Protista like the Euglena to move in water environments flagellum
tiny hair-like structures to move back and forth to move in a water environment cilia
takes in food particles and breaks them down to convert them to energy for the cell to complete processes mitochondria
used for storage of water, food, and waste; larger in the plant because of photosynthesis vacuole
