Plant sterols can block the absorption of cholesterol and are found in fruits, vegetables, nuts, seeds, legumes, and grains. They are often added to food to help reduce the risk of coronary heart disease, but consuming more than three grams per day may not increase their benefits. It is recommended to use other methods of […]
Becoming a gas plant operator requires a high school diploma and related courses, with a technical degree or online program increasing chances. Experience and certifications, such as OSHA’s Operator Qualification courses, can also help. On-the-job training covers gas properties, plant safety, and emergency procedures, with factory training covering equipment maintenance and repair. Becoming a gas […]
Becoming a chemical plant operator requires attention to detail, problem-solving skills, and on-the-job training. A high school diploma and courses in chemistry, math, physics, and industrial arts are helpful. The job involves monitoring systems, adjusting equipment, quality control, and emergency response. Chemical plants are located worldwide, and operators can specialize in different types of chemicals. […]
Plant estrogen, or phytoestrogen, is a non-steroidal compound found in plants that has similar effects to human estrogen. It is not considered a nutrient but is found in foods like soybeans and flaxseeds. Research has shown potential benefits for menopausal symptoms and diabetes, but its effects on breast cancer are still unclear. Plant estrogen, also […]
Chemical plants produce a variety of chemicals using different processing techniques, with safety being a major concern. Chemical engineers design and manage these plants, while environmental regulations have led to increased scrutiny. Petrochemical plants run on petroleum-derived chemicals and are often located next to oil refineries. A chemical plant is an industrial facility designed for […]
Plant ecology studies plant populations and their interactions with the environment, including animals and soil conditions. It encompasses topics such as climate change, plant evolution, and diseases. Fieldwork is important for researchers to understand plants in context. Plants are vital to ecosystems, providing food, shelter, soil protection, shade, water conservation, and oxygen production. Plant ecology […]
Plant cells have a rigid cellulose-based cell wall and a large central vacuole. They have three types of tissue: surface, basic, and vascular. Epidermal cells can be specialized as guard cells or for water absorption. Basic tissue types include parenchyma, collenchyma, and sclerenchyma. Xylem and phloem are the two types of vascular tissue. Plant cells […]
Plant mitosis is the process of cell division that creates two identical daughter cells. The phases are interphase, prophase, metaphase, anaphase, telophase, and cytokinesis. During interphase, the cell prepares for mitosis. In prophase, chromatin condenses into chromosomes. In metaphase, chromosomes move to opposite ends of the cell. In anaphase, pairs of chromosomes separate. In telophase, […]
Plants include 375,000 species, with 297,326 identified, and are photosynthetic with chloroplasts. They consist of green algae and terrestrial plants, with vascular plants being the most dominant and bryophytes being less advanced. Seeds allowed plants to colonize drier areas, and flowering plants evolved to involve mobile animals in pollination. There are an estimated 375,000 plant […]
A pig plant slaughters, processes, and prepares pigs for sale, and may also process other animals. Pigs are led through a route to reduce stress before being stunned and slaughtered. The carcass is then cleaned, cut, and prepared for sale. A pig plant is a facility where pigs are slaughtered, cleaned, processed and prepared for […]
Meatpacking plants process and distribute animals to buyers worldwide, but animals are not slaughtered inside the plants. Working conditions have improved since the early 1900s, and unions protect workers from unfair conditions. Kosher and halal packing plants must be separate from other facilities, and farm-killed meat is becoming more popular. A meatpacking plant is a […]
Petrochemicals are products made from oil or gas and are traded internationally, with various types and uses. Petrochemical plants use different methods and configurations, but all require specialized equipment and highly trained personnel. They are often located near oil and gas refineries, but proximity to raw materials does not always guarantee maximum production. Petrochemicals are […]
Gas turbine plants use natural gas to produce electricity by heating water to create steam that turns a turbine. It is the third most common way of producing electricity, with environmental benefits. A hybrid plant, using centralized gas turbines, can increase efficiency by up to 60%. Gas turbine plants produce less carbon dioxide, mercury, and […]
Wastewater treatment plants remove harmful contaminants from liquid waste before releasing it back into the environment. Jobs range from entry-level to supervisory positions, with certification and continuing education required. Small municipal plants require a full range of tasks, while larger facilities have more focused tasks. Wastewater treatment plants remove harmful contaminants from liquid waste before […]
Plants rely on their vascular system to transport water and nutrients, with xylem transporting water and phloem moving organic nutrients. The system is found in vascular bundles and includes a layer called the vascular cambium, which segregates xylem and phloem and is responsible for stem cell differentiation. The plant vascular system, filled with tube-like vascular […]
Gas production plants converted coal or oil into gas for lighting, heating, and cooking. They were common from the late 1800s to mid-1900s, but were replaced by natural gas. The plants relied on carbonization or gasification to create gas and produced useful by-products. Most sites have been dismantled due to toxins, but Gas Works Park […]
Cement mills grind clinker, a hard material produced by sintering aluminosilicate and limestone in a kiln, into fine particles. Ball mills are the most common type of cement mill, using steel balls to crush and grind the material. High-pressure roller mills are occasionally used but less widely accepted. The main constituent of Portland cement is […]
