The cell is the most basic unit of life. In the human body, cells compose of all the tissues and organs and are in constant communication with each other to maintain the functions needed to grow and survive. Thi
Is the major site of cellular metabolism. 12 organelles: a general term for various subcellular structures with specific functions in the cytoplasm. 13, cell wall: plant cells outside the cell wall, the main chemical components are cellulose and pectin, its role is to support and protect. Its...
The precise location of cells in the multicellular organisms and the location of intracellular organelles within cells are vital in the normal development and function. In the simplest forms of life, such as the bacteria, cellular organization and biochemical functions are relatively uncomplicated and ...
Structure and Function of Cells Organelle –“little organ” these are the structures found in cells that carry out the activities of life within the cell Cell Membrane Outer boundary of cell Protects the cell Controls what enters and leaves the cell Also called – plasma membrane Is semi-permea...
Cytoplasm A thick, clear, gel-like fluid that fills the regions between the cell membrane and the organelles of Eukaryotic cells. Organelles are tiny cell structures that carry out specific functions with-in the cell. 8 Nucleus The nucleus is the cell’s control center, directing all of the ...
Diffusion and Cell Membranes Purpose: The purpose of this lab is to test the effects of osmosis on eggs in hypertonic solutions and hypotonic solutions. Hypothesis: If the corn syrup is a hypertonic solution‚ then the egg’s size will shrink. If the water is a hypotonic solution‚ then...
Knowledge of cell chemistry is also important in the diagnosis of disease and developing drugs to counteract adverse medical conditions e.g. anti-cancer drugs. What is a cell? A cell is the smallest unit of life able to control its own activities, BUT, it relies on the rest of the organi...

Human Biology Unit 1 Assignment. A cell is a small membrane enclosed structure filled with an aqueous solution where the organelles are found. Organelles are...
The major determinant of small RNAs that functions as specific triggers of gene silencing is the A-form helical geometry of RNA. The A-form helix and high-resolution structural studies provide a context for discussing the importance of phosphate groups at the 5′ end of the guide strand. ...
