Viruses have their own peculiarities. They are a group of very simple and very small organisms, which consists of a strand of nucleic acid surrounded by a coat of protein. All are now known as parasites, which are capable of reproducing in the living cells of host animal, plant, or microorganism. They cannot be cultivated on artificial media as many bacteria can. These peculiarities, together with the production of crystal like forms, are unusual in living organisms and have led some investigators to regard viruses as lying athwart the line dividing the inanimate from the animate. 1.  A virus can be cultured in an artificial media to study its life cycle. a.

The outer membrane is fairly smooth. But the inner membrane is highly convoluted, forming folds called cristae. The cristae greatly increase the inner membrane's surface area. It is on these cristae that food (sugar) is combined with oxygen to produce ATP - the primary energy source for the cell. Mitochondria's main role is the production of ATP (adenosine tri-phosphate) which is the principal energy storage molecule of the cell (it is also a component for the synthesis of nucleic acids (RNA and DNA) and it can act as a neurotransmitter) ATP is produced in the electron transport chain which uses products of the Krebs cycle which is itself linked to the metabolism of sugars, fats and amino acids. Mitochondria contain their own DNA which codes for some but not all the proteins found in mitochondria. It is believed that originally mitochondria were independent organisms that early on in evolutionary history have entered a symbiotic relationship with unicellular organisms. Mitochondria are inherited only through the mother line (the sperm does not contribute mitochondria to the egg) 4.  Mitochondria is inherited through: a. Maternal side b. Paternal side c.

Please describe the changes made by you   This Question is based on the following passage:   The three major functions that are basic to plant growth and development are: Photosynthesis – the process of capturing light energy and converting it to sugar energy, in the presence of chlorophyll using CO2 and H2O,Respiration – the process of metabolizing (burning) sugars to yield energy for growth, reproduction and other life processes, and Transpiration – the loss of water vapor through the stomata of leaves. Photosynthesis and respiration are complementary processes in the living world. Photosynthesis uses the energy of sunlight to produce sugars and other organic molecules. These molecules in turn serve as food for other organisms. Many of these organisms carry out respiration, a process that uses O2 to form CO2 from the same carbon atoms that had been taken up as CO2 and converted into sugars by photosynthesis. In the process, the organisms that respire obtain the chemical bond energy that they need to survive. 6.  Which molecules are the available source of energy in all living cells? a. Glucose b.

Protein molecules are essential to us in variety of different ways. Much of the fabric of our body is constructed from protein molecules. Muscle, cartilage, ligaments, skin and hair - these are all mainly protein materials. The protein in the food we eat is our main source of the chemical building blocks we need to build our own protein molecules. The primary structure of a segment of a polypeptide chain or of a protein is the amino-acid sequence of the polypeptide chain(s), without regard to spatial arrangement (apart from configuration at the alpha-carbon atom). The sequence and properties of side chains determine all that is unique about a particular protein, including its biological function and its specific three-dimensional structure. 8.  The colors of light in the visible range in a spectrum from longest wavelength to shortest are ______.   a.
