Nutrients in Aquatic Ecosystems

Source: Laboratories of Margaret Workman and Kimberly Frye - Depaul University Nitrogen and phosphorus are essential plant nutrients found in aquatic ecosystems and both are monitored as a part of water quality testing because in excess amounts they can cause significant water quality problems. Nitrogen in water is measured as the common form nitrate (NO3-) that is dissolved in water and readily absorbed by photosynthesizers such as algae. The common form of phosphorus measured is phosphate...

A schema is a mental framework that helps individuals organize and interpret information. Schemata, formed from previous experiences, influence how we process new information: how we encode it, the inferences we make, and how we retrieve it. For instance, a schema for what a typical classroom looks like might include desks, a teacher's desk, a whiteboard, and students in such an environment. This expectation helps us quickly understand and navigate new classrooms without needing to analyze each...

Here, we present an easy-to-follow protocol to establish a successful hydroponic system for plant nutrition studies. This protocol has been extensively tested in Arabidopsis and can easily be adapted to other plant species to study specific nutritional requirements or the effect of non-essential elements on plant growth and development.

Absorption of Nutrients

Absorption refers to taking dietary nutrients from the intestinal lumen for transportation throughout the body. After digestion in the small intestine, carbohydrates, proteins, and fats are broken down into simpler forms. These essential macronutrients and other vital substances, such as vitamins, minerals, and water, are then prepared for absorption into the bloodstream. Enterocytes, which are specialized polar epithelial cells, line the mucosa of the small intestinal walls. These cells...

Soil Nutrient Analysis: Nitrogen, Phosphorus, and Potassium

2023
Source: Laboratories of Margaret Workman and Kimberly Frye - Depaul University In this experiment, three soil macronutrients are chemically extracted, combined with color-based reagents, then analyzed using color to determine the nutrient concentration present in the soil sample. Nitrogen, phosphorus, and potassium are the main components of soil fertilizer. These methods isolate each nutrient from the soil into a solution that can be analyzed using turbidity and color to determine the...
FAQs
The key mechanistic step is converting excess nutrients into stable forms that cells can retain without immediately using them. Glycogen, starch, and triglycerides represent distinct storage forms for different biological contexts. When energy or materials become limited, these reserves can be mobilized, linking storage with continued cellular function, growth, reproduction, and survival.
Storage forms match the organism and the nutrient being retained. Animals store carbohydrates as glycogen and lipids as triglycerides, while plants store carbohydrates as starch. Specialized structures, including vacuoles and lipid droplets, help sequester these materials and support their later mobilization. This organization connects chemical storage with the needs of particular cells and organisms.
Changing food or environmental conditions can alter the balance between retaining nutrients and using reserves. During periods of limited food, stored materials provide resources that support metabolism and other essential functions. This capacity gives organisms a way to cope with fluctuating resource availability while preserving the materials needed for growth, reproduction, and survival.
Examining nutrient storage can show how organisms manage energy beyond immediate consumption. Researchers can relate stored carbohydrates, lipids, and minerals to energy balance, cellular function, and the later use of reserves. These observations help connect nutrient handling with broader biological questions about metabolism and how organisms remain functional when resource conditions change.
In plants, starch storage provides a biological context for examining how retained carbohydrates relate to productivity. Studying where and how these reserves are maintained can connect nutrient handling with plant growth and changing environmental conditions. The comparison with animal glycogen and triglyceride storage also highlights how different organisms organize resources for later biological use.
A study of nutrient storage can assess relationships among stored reserves, metabolism, growth, reproduction, and survival. It may also examine how vacuoles, lipid droplets, or other storage arrangements contribute to retaining and mobilizing nutrients. These outcomes provide context for understanding metabolic disease, plant productivity, and adaptations to limited or variable resources.
