Assignment 4: Bataan Nuclear Power Plant The Bataan Nuclear Power Plant (BNPP) is located in Morong‚ Bataan and was constructed under the administration of President Ferdinand Ferdinand Marcos during the Martial Law period. Westinghouse was contracted to build the light water reactor‚ deign to produce 621 megawatts of electricity. This power plant was constructed under loan $600 million for two units but controversially it ballooned up to $2.3 billion. After The Marcos’ was thrown to Hawaii‚ the

Plant and animal cells have several differences and similarities. For example‚ animal cells do not have a cell wall or chloroplasts but plant cells do. Animal cells are round and irregular in shape while plant cells have fixed‚ rectangular shapes. Animal Cell Plant Cell Cell wall Absent Present (formed of cellulose) Shape Round (irregular shape) Rectangular (fixed shape) Vacuole One or more small vacuoles (much smaller than plant cells). One‚ large central vacuole taking up 90% of cell volume

Chapter 35 Plant Structure‚ Growth‚ and Development Lecture Outline Overview: Plastic Plants? • The fanwort‚ an aquatic weed‚ demonstrates the great developmental plasticity that is characteristic of plants. o The fanwort has feathery underwater leaves and large‚ flat‚ floating surface leaves. o Both leaf types have genetically identical cells‚ but the dissimilar environments in which they develop cause different genes involved in leaf formation to be turned on or off.

The Effect of Gasoline Fumes on plants Introduction: This science fair project was conducted to study the effect of gasoline fumes on plants. The testing was done by placing plants beside a gasoline-filled container for different periods of time and temperatures. Hypothesis: Gasoline fumes cause plants to die - the longer the exposure to the fumes‚ the quicker the plants will die. Our second hypothesis is that exposure to fumes‚ at higher environmental temperatures‚ will result in quicker

Functions and structure of plant terpenes Terpenes are an enormous class of organic compounds‚ that are produced by a wide variety of plants and fungi‚ especially conifers. Terpenes are also produced by some of the living organisms‚ like swallowtail butterflies. They emit terpenes from their osmeterium. Terpenes are important materials for a plant as components of its body and as a material to protect it from external enemies since it has a strong smell and colorless. Terpenes are found in biological

similarities between plant and animal cells are as follows: 1. Both are constructed from eukaryotic cells. 2. Both contain a defined nucleus. 3. Both have mitochondria. 4. Both have Golgi bodies. 5. Both are surrounded by a cell membrane. Three differences are: 1. Plants cells have a cell wall‚ whereas animal cells do not. 2. Animal cells have lysosomes‚ whereas plant cells do not. 3. Animal cells contain centrioles and a cytoskeleton‚ whereas most plants do not. Five
