-Groups of similar cells that work together to perform a specific task or function-Blood BLANK is made of simimlar (blood cells) that work together to do a job.
-Group of different tissues that work together to perform a specific task or function-Your heart is an BLANK made of blood tissue, muscle tissue, nerve tissue, and connective tissue-The different tissues work together to perform a specific task.
Organ System
-Group of different organs that work together to perform a specific task or function-your digestive system is a group of organs (mouth, esophagus, stomach, small / large intestine, liver) that work together to perform a specific task.
-Has a group of organ systems that work together to perform a specific task ( Making up the BLANK ) and sustaining life.
Robert Hooke
-Gave cells their name-Looked at dried out cork-Saw dried out cells-Reminded him of monastert cells.
-Smallest unit of life in all living things-Carries on the activities of life.
-Some animal cells have BLANK that store food, water, wastes, and other materials.
Golgi Body
-The BLANK receive materials from the endoplasmic reticulum and send them to other parts of the cell. They also release materials outside the cell.
-The BLANK is the area between the cell membrane and the nucleus. It contains a gel-like fluid in which many different organelles are found.
-Most of the cells energy is produced within these rod-shaped organelles.
Cell Membrane
-Since an animal cell does not have a cell wall, the BLANK forms a barrier between the cyoplasm and the environment outside the cell.
-These small organelles found in many animal cells contain chemicals that break down food particles and worn-out cell parts.
-Almost all animal cells contain a BLANK. The BLANK directs all of the cell's activities, including reproduction.
-These small structures function as factories to produce proteins. BLANK may be attached to the outer surfaces of the endoplasmic reticulum, or they may float free in the cytoplasm.
Endoplasmic Reticulum
-This network of passageways carries materials from one part of the cell to another.
Cell Wall
-In a plant cell a stiff wall surrounds the cell membrane, giving the cell a rigid boxlike shape.
-These organelles capture energy from sunlight and use it to produce food for the cell. Only on plants.
Characteristics of bacteria
-Live almost everywhere. 3 basic shapes round-cocci, rod-bacilli and spiral-spirilla.
Feautures bacteria use to help them survive
-Capsule, capsule and hairlike projections, slime layer and flagella.
-Different cells do different jobs-they look different (shapes and sizes)-shape and size of cell is due to it function.
Cell Theory
- (1) All living things are made of one or more cell- (2) The cell is the basic unit of life in which the activities of life occur- (3) All cells come from cells that already exist.
What is the main way bacteria reproduce
-The way BLANK is by fission. Fission is a process that produces two new cells with ,genetic material identical to each other and that of the original cell.
What is the difference between consumer bacteria or producer bacteria
-BLANK make there own foood others get it from the envirment. BLANK bacteria break down dead organisms to obtain energy. Other use living organisms as food.
Aerobic Bacteria
-BLANK bacteria can grow where oxygen is present.
Anaerobic Bacteria
-Some BLANK bacteria will grow only where there is no oxygen. Other BLANK bacteria can grow in areas with or without oxygen.
-Cyanobacteria is important because they are a source of food for some organisms im lakes, ponds, and oceans. They are blueish, greenish.
What is the difference between Archaebacteria and Eubacteria
-You would find BLANK in salty and icy enviroments. BLANK can live everywhere.
-Bacteria make food through BLANK.
Cellur Respiration
-Series of chemicals to store energy into food.
-The use of organisms to help clean up.
-Organisms that use dead organisms as food or energy.
-Cell structure that has a specific job.
