11. Cytoplasmic matrix: the part of the cytoplasm that is liquid and the stroma. 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 ...
The fundamental unit of structure in biology is the living cell. Regardless of whether an organism is single celled or multicellular, it must carry out the same basic functions in order to survive, both as an individual and as a species. These functions include acquisition of nutrients and ...
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. This chapter will focus on the mechanisms relevant to cell signaling and cell divi...

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...
Cell is the basic functional unit that makes up all living organisms. All organisms, including ourselves, start life as a single cell called the egg. Cells are small microscopic units that perform all essential functions of life and are capable of independent existence. ...

The Mitochondrion (mitochondria plural) is a rod-shaped organelle that is functions as the cells’ power generator that converts oxygen and nutrients into adenosine triphosphate or ATP. ATP is the chemical energy of the cell that powers all the metabolic activities of the cell. Such process is ...
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 ...
