Sympathetic Nervous System The sympathetic nervous system is often called the fight or flight division. It results in increased alertness and metabolic activities to prepare the body for an emergency situation. It regulates responses during physical activity or emotional stress such as increased heart rate, dry mouth, cold skin and blood supply to arteries.

The cell wall is freely permeable allowing the substances in solution to enter and leave the cell without hindrance 12 The plant cell shown in Fig. 2.6 also shows portions of the cril walls of six surrounding cells. A thin middle layer (shown as a thick grey line) holds the two adjacent cells together. Cotton, jute and coconut fibres are the cell walls of their dead cells 2.8.2 Cytoplasm Cytoplasm is a semi-liquid substance. It occuples most part of the cell within the cell membrane. Under a compound microscope, it appears to be colourless, partly transparent and somewhat watery Many chemical reactions take place in the cytoplasm. Living cytoplasm is always in a state of some movement. The following are the cell organelles embedded in the cytoplasm : 1. Endoplasmic reticulum The endoplasmic reticulum (ER) is so fine in structure that its existence is revealed only through an electron microscope (Fig. 2.6). It is an irregular network of double membranes distributed over the entire cytoplasm in a cell. At its outer end, endoplasmic reticulum is connected with the cell membrane. . At its inner end it is connected with the nuclear membrane. It appears rough when small granules called ribosomes are attached to it and appears smooth without them. It forms the supporting framework of the cell and also serves as a pathway for the distribution of the materials from one part of the cell to the other. 2. Ribosomes - The sites of protein synthesis The ribosomes are numerous small granules either scattered freely in the cytoplasm or attached to the membranes of the endoplasmic reticulum. These are the 'factories for the synthesis of proteins. PARTS OF A CELL Living Parts Cell membrane In the Cytoplasm 1. Endoplasmic reticulum 2. Mitochondria 3. Golgi apparatus 4. Ribosomes 5. Lysosomes 6. Centrosome (only in animal cells) 7. Plastids (only in plant cells) Non-living Parts Cell wall (only in plant cell) 1. Nuclear membrane 2. Nucleoli 3. Chromatin fibres 1. Granules 2. Vacuoles 3. Fat droplets In the Nucleus 1. Nucleoplasm 3. Mitochondria - The cell's energy producers The mitochondria (sing: mitochondrion) are spherical or rod-shaped bodies. These are minute double-walled bags with their inner walls produced into finger-like processes projecting inwards (called cristae). Mitochondria are the sites where cell respiration occurs to release energy. This energy is stored in the form of an energy-rich compounc ATP (adenosine triphosphate) and is used in variou metabolic functions of the cell, and in turn, of the body. Because they store ATP, mitochondria an called "power houses of the cell". Mitochondr contain their own DNA which can replicate. 4. Golgi apparatus - The delivery system of th cell The golgi apparatus occurs in the form of granul filaments or rods which are supposed to be origina from endoplasmic reticulum. These are very sm vesicles of different shapes, and are generally loca near the nucleus. The golgi complex consists of m small groups of hollow tubular structures membranous walls, called cisternae, and is assoc with some minute vesicles and vacuoles. C CONCISE BIOLOGY
