Trachea. 12. Consider a cell with cilia beating on its surface. Identify one other organelle that would be expected to assist in the action of these cilia. a. Mitochondria would be present to assist the action of the cilia because energy is needed. 13. List four cell organelles that are involved in the process of making protein. What is the contribution of each organelle to this process? a. Four cell organelles involved in the process of making protein are: i. Nucleus: has coded instructions

History of microorganisms’ discovery Anton van Leeuwenhoek was the one of the first people to observe microorganisms‚ and used a microscope of his own design‚ and made one of the most important contributions to biology. [18] Robert Hooke was the first to use a microscope to observe living things; his 1665 book Micrographia contained descriptions of plant cells. Before Leeuwenhoek’s discovery of microorganisms in 1675‚ it had been a mystery why grapes could be turned into wine‚ milk into cheese

The cell is the basic functioning unit of organisms in which chemical reactions take place. These reactions involve an energy release needed to support life and build structures. The cell consists of membrane bound organelles‚ which are responsible for the division of labour. There are two main classes of cells- Prokaryotes which are cells without a nucleus‚ where the DNA is spread around the cytoplasm of the cell‚ an example of a prokaryote is a bacterium (See Figure 1). The other class is the Eukaryotes

a Hospital Cameron Browne The main organelle is the nucleus. I think the nucleus is like the hospital administration because the nucleus is the core of the cell that handles everything‚ and the hospital administration handles everything that goes on in the hospital. Without the “cores” for both the hospital and the cell‚ neither could properly functions. The nucleolus is the center of the nucleus‚ and it basically sends out all of the other organelles that work within the cell. I compared the

General Biology (BI131 01) The Cell Structure and function Abstract In this lab the structures of various cells were viewed through a compound microscope. The bacteria in yogurt was viewed a long with a slice of potato‚ and a thin skin of red onion. The potato was dyed with iodine while the red onion was dyed with methane blue. The students had to assemble the first three slides. Two more slides were provided these are the yeast and protozoa cells

and altered organelles‚ which turns into toxicity for the muscle cells (Sandri). 5. Conversely‚ excessive activation of proteolytic machinery‚ including lysosomal-dependent degradation‚ contributes to muscle loss‚ weakness‚ and finally to death (Sandri). 6. These findings will help to define the role of the lysosomal system in muscle homeostasis during physiological or pathological conditions (Sandri). 7. Lysosomes control the half-life of long-lived proteins and the turnover of organelles and therefore
