The phloem collects photoassimilates in green leaves, distributes them in the plant and supplies the plant organs. The phloem is specially designed for loading, long‐distance transport and unloading of assimilates. The conducting cells are called sieve elements. These cells are highly modified to create a simple pathway of contiguous living cells, whose long‐term viability is maintained [...]

Aren’t these roots in the picture beautiful? We wish we lived in a world where all roots looked this way, but sadly we don’t. Because we live in the real world, houseplants, trees, plants, or shrubs are often overwatered; their leaves start to get dull, turn yellow and the plants will show other signs of stress. [...]
Roots are the primary way in which plants acquire nutrients. Plant roots can penetrate to significant depths and are branched so that they can explore large volumes of soil. Some nutrients are only “weakly bound” in the soil, and can flow towards the root surface when a plant uses water. Other nutrients can be tightly bound [...]
Plants absorb water through their entire surface - roots, stems and leaves. However, the majority of water is absorbed by root hairs. Root hairs are thin-walled uni-cellular outgrowths of epidermis. They are in close contact with the thin film of water surrounding the soil particles. The cell wall of the root hair is permeable to water [...]
Roots are vital to plant life in large variety of ways. Not only do they provide stability and nutrient storage, they’re also the main source of acquiring nutrients and water. Typical roots contain many different working parts that work together to sustain and grow the plant. We have laid out each of the basic parts of [...]
If you garden, then you know vegetables are grown virtually everywhere. However, you also know that the soil those vegetables are grown in has a huge impact. Soil can simply be defined as the portion of the Earth’s surface where plant growth occurs. Even though many people call it dirt, there is a lot more to [...]
When it comes to your plants, selection of soil or growing medium is often overlooked. It is important to understand that selecting a growing medium is important to your plants’ success, so make sure you know what materials were blended into the mix you are purchasing. When the job you’re undertaking is smaller many people feel it [...]
Hydroponics is the growing of plants in a liquid nutrient solution with or without the use of artificial media. Commonly used media include expanded clay pellets, peat coir, perlite, vermiculite, brick shards, polystyrene packing peanuts and wood fiber. Hydroponics is a viable method of producing vegetables, foliage plants and other crops. The demand for locally grown produce has risen [...]
Soil serves many purposes as a medium for plant growth. It works as an anchor, a water holding tank, stores and supplies plant nutrients, influences fertility and that’s just to name a few things. The impact of soil is far reaching and is a key component of successful growing. We know of its importance, but what [...]
The word sodium is often associated with many different things in our society today. It is most commonly associated with sodium chloride, common table salt, and the major component of sea water. Many people think very negatively about sodium chloride and its value to the human body, animals and plants. Sodium was determined to be an [...]
