Fundamental Unit of Life. Cells are the basic structural and functional unit of life.
Cellular respiration is the process by which the food releases energy in the mitochondria. Cells absorb glucose from the food and burn it to produce energy.
Osmosis is the movement of water across a semi-permeable membrane.
Hypotonic solutions contain lesser amount of solute concentration compared to the surrounding fluid.
Hypertonic solutions contain higher concentration of solute compared to the surrounding fluid
Isotonic solutions are those which have the same solute and pH concentration
Cell Membrane
Cell membrane is the outer covering of a cell.
It is made up of phospho-lipid bilayer membrane.
It is selectively permeable in nature.
Two types of cell; Prokaryotic and Eukaryotic cells. Prokaryotic cells are primitive and lack well defined nucleus. Eukaryotic cells are more advanced and have well defined nucleus.
Endocytosis is the invagination of cell membrane
Nucleus is the processing unit of the cell.
Chromatin is a thread like structure which serves as the genetic material present inside the nucleus of the cell.
Organelles are structures present in the cytoplasm of the cell that help in several functions of the cell.
The rest of the organelles include:
ER
Lysosomes
Golgi Bodies
Mitochondria
Plastids
Vaculoues
