Cellular Respiration Photosynthesis Organelles Mitochondria Chloroplast Organelle Structures The double-membraned mitochondrion can be loosely described as a large wrinkled bag packed inside of a smaller‚ unwrinkled bag. The two membranes create distinct compartments within the organelle‚ and are themselves very different in structure and in function. Two membranes contain and protect the inner parts of the chloroplast. The stroma is an area inside of the chloroplast where reactions occur and starches

of the specialized underlying structures of these life-forms. In order for us to appreciate these special adaptation‚ we first need to know how a typical plant or an animal cell organelle behaves in different water and solute concentrations. In this lab‚ we will determine the effects of hypertonic‚ isotonic and hypotonic solutions on plant and animal cells. In general when an animals cell’s placed in hypertonic solution it shrivels; a plant cell on the other hand undergoes plasmolysis. When an animal

ASPECTS OF MATERIALS CONTROL The main aspects of materials control are the physical control or safeguarding of materials. Physical control protects materials from misuse or misappropriation. Maintaining an appropriate level of raw materials inventory is one of the most important objectives of materials control. An inventory of sufficient size and variety for efficient operations must be maintained‚ but the size should not be excessive in relation to scheduled production needs. Every business requires

Smart and modern materials Textiles Home Learning Project Year 8 Estelle Crossley Smart materials Smart materials have properties that react to changes in their environment. This means that one of their properties can be changed by temperature‚ light‚ pressure or electricity. This change is reversible and can be repeated many times. There are a range of different smart materials. Each offer different properties that can be changed. Modern materials with new properties are excellent

these can be characterized‚ and how quality teaching can be achieved and maintained. a. Teaching Model and Principles This book has emphasized the curriculum as a network of interacting system involving teacher‚ learners‚ materials‚ school‚ administrator‚ and curriculum planners‚ and choices ay one level affect other elements in the system. Thus the choice of a particular curriculum philosophy or ideology implies a particular model of teaching. Roberts (1998‚ 103) compares

Metallic element gives up valence electrons to the nonmetallic elements. Attractive forces from positive and negative ions Ceramic materials: high melting temperatures‚ hard‚ poor conductors Covalent Bonding Electrons are shared between adjacent atoms resulting in stable electron configurations. Many nonmetallic elemental molecules are covalently bonded. Polymeric materials have this bond. Crystal Structure Describe the crystal structure using an array of points or lattice.
