Organization & Cells

2.1
describe the levels of organisation within organisms: organelles, cells, tissues, organs and systems

 

Organelles - intracellular structures that carry out specific functions within a cell
Cells - the basic structural and functional unit from which all biological organisms are made
Tissues - a group of specialized cells, which are adapted to carry out a specific function
Organs - a collection of two or more tissues, which carries out a specific function or functions
Organ Systems - a group of two or more organs working togthere

describe cell structures, including the nucleus, cytoplasm, cell membrane, cell wall, chloroplast and vacuole

describe the functions of the nucleus, cytoplasm, cell membrane, cell wall, chloroplast and vacuole

animal cell structure: 

Nucelus an organelle which contians genetic material that controlls the cells activity and is surrouned by its own membrane 

cell membrane  this membrane forms the outer surface of the cell and controls the substances that move in and out of the cell 

cytoplasm; gel like substance where most of the cell's chemical reaction take place, it also contians enzymes which control these reactions 

plant cell structure 

chloroplast is where photosyntheisis takes palce  which makes food for the
