Basic Processes of Reproduction Bacteria: Bacteria reproduce asexually, under positive environment settings this process is carried out through the method binary fission, where the most bacterial reproduction occurs in prokaryotic cells. The second method is through mitosis in eukaryotic cells except gametes (Pruitt & Underwood, 2006). Binary fission is asexual by nature and involves the splitting of the parent cells into two equal parts which once the split can be capable of independent

(Glucose + 6O2 + 6H2O + Energy) Breaking down process. Is the capacity LO have to break-down food to obtain energy. Most need oxygen. (p. 19) Excretion: Breaking down process. Is the capacity LO have to respire and other chemical changes in the cells that produce waste products such as Carbon Dioxide. Irritability: Irritability is an excessive response to stimuli. The term is used for both the physiological reaction to stimuli and for the pathological, abnormal or excessive sensitivity to stimuli;

process where cell division takes place equaling into a different phases where the cell is being replicated into two identical groups. Interphase, Prophase, Prometaphase, Metaphase, Anaphase and Telophase are nuclear division including cytokinesis that supports the cell division in the cell cycle. Meiosis is similar process to Mitosis but its more special, which segregates one cope of each homologous chromosome into new gametes, which contains a single copy of chromosome. Each cell after cell division

of reproduction for yeasts is asexual reproduction through budding. In this process, the parent cell’s nucleus splits and forms a daughter nucleus. The daughter cell grows on the parent cell until it is large enough to separate. Through cytokinesis, this ‘bud’ then forms a new cell. Less common is the method of sexual reproduction in which spores are formed. In this lab, I will be culturing four yeast samples under different conditions. The goal is to study the effects of limited reproduction, additional

a prokaryotic and a eukaryotic cell. ANSWER: Prokaryotic and Eukaryotic organisms: are composed of cells, the basic unit of life, with each cell surrounded by a cell membrane while membranes are composed of phospholipids, proteins and carbohydrates arranged in a fluid mosaic structure. The main different between the both cell organism is nucleus: Prokaryotic cells are smaller and simpler organisms without no nucleus but most are unicellular, while eukaryotic cells are larger organisms with a nucleus

development and growth, reproduction, homeostasis, regulation and processing energy. When we view these together the eight items define life. Organisms and creatures are organized and coordinated structures that consist of one or more cells. Even the very simple, single-celled organisms and creatures are complex. Inside each cell atoms make up molecules, these atoms and molecules in turn make up organelles and other inclusions. In a multicellular organism or creature similar cells from tissues. These

Mitosis results in daughter cells that are genetically identical * That have the same number of chromosomes as the parent cell * The division allows the production of cells that are genetically identical to the parent and so gives genetic stability * By producing new cells, mitosis is important in growth of an organism * And also allows for repair of tissues and the replacement of cells and repair to wounds etc * Mitosis is an Asexual reproduction, this

substances in excess. 3. Respiration: Chemical reactions that break down nutrient molecules in living cells to release energy. 4. Sensitivity: The ability to detect or sense changes in the environment and to make responses. 5. Reproduction: Progresses that make more of the same kind of organism. 6. Growth: The permanent increase in size and dry mass by an increase in number of cells, cell size, or both. 7. Movement: An action by an organism or part of an organism that changes position

living organisms have a definite shape and size as well as physical and chemical composition inherited from their parents. This is possible because of a high degree of organization. The molecules of which an organism is made up are organized into cells, which in turn are organized into tissues, organs and organ systems making the whole individual. This kind of complex organization is not found in non-living things. Metabolism Green plants obtain their nourishment from the environment in the form
