Biology HL Portfolio The Cell and Cell Theory [pic] The cell The word cell comes from the Latin word “cellula”‚ which means a small room. The cell is the smallest unit of a living organism‚ also known as “the building block of life”. Every living organism is consisted of a cell. There are bacteria (unicellular organisms)‚ and multicellular organisms. There are different types of cells‚ prokaryotic and eukaryotic cells. All cells come from preexisting cells. “Every cell is self-maintaining;

that store all the information that the body inbeds such as how one looks and functions. This paper will first describe the structure of DNA; second discuss how the structure of DNA allows it to serve as the basis for inheritance‚ third examine how meiosis allows DNA to be divided into gametes and finally‚ describe how this relates to Gregor Mendel’s patterns of inheritance. The structure of DNA DNA is a thread formed by two strands‚ related together to form a Double Helix. The Double Helix looks

we have learned in class new cells form from old cells through the process of meiosis and mitosis. In meiosis‚ chromosome pairs synapse‚ cross over‚ align‚ and separate twice. The crossing over results in the mixing of genetic information between the chromosome pairs. When they separate‚ they divide and form four cells with varied genetic material‚ resulting in offspring that are varied forms of their parents. In mitosis‚ chromosomes divide and form two cells with no change in genetic material‚ resulting

Before the chromosomes condense the nuclear membrane goes through meiosis which is cell division between and egg and sperm cell that determines the sex of a baby. The sex is found by the sperm which carries a X and Y sex chromosomes. Before the cell divides two sets of chromosomes pair together and swap segments. The second
