Their role may be simply thought of as extending the surface area of the root to facilitate absorption of nutrients and water. However, as you will see in this book, the root hair is far more than that. To an increasingly larger number of plant biologists, the root hair is a model ...
25 Which features adapt root hair cells for efficient absorption of water?D1 a large number of mitochondria2 a large number of protein carriers in the cell surface membrane3 a large surface are a to volume ratio A 1, 2 and 3 B 1 and 2 only C 2 and 3 only D 3 only 相关知识点:...

Root hairs are single cells specialized in the absorption of water and nutrients from the soil. Growing root hairs require intensive cell-wall changes to accommodate cell expansion at the apical end by a process known as tip or polarized growth. We have recently shown that cell wall ...
Root water uptake refers to the process in which plant roots absorb water from the soil, which is a crucial aspect of plant physiology and ecosystem functioning.This process involves multiple mechanisms, including osmosis, root hAIr absorption, and the role of aquaporins.Among these, osmosis plays...
the epidermal cells proximal to the root tip develop hair-like extensions calledroot hairs(Figure 10.12A; seeFigure 4.9A); root hairs function togreatlyincrease thesurface areaavailable for water and mineral absorption. Third, roots have no exogenous (externally developing) organs; alllateral roots ...
mentioned, hair 15000000000, if connected, a total length of 10000 kilometers, is the Beijing distance to Paris.So a plurality of wool, significantly increased the total absorption area of root hair zone of epidermal cells. The root hair cell skin is thin, a little cytoplasm,...
Root hairs perform multiple key functions in the plant growth and developmental process, notable among which is absorption and subsequent transfer of water, nutrients, and minerals from soils, plant-microbe interactions, and sequestration of toxic metals in selected cases (Datta et al., 2011). A ...
Root hairs are tiny, hair-like structures that grow on the surface of the plant roots. Their main function is to increase the area available for water absorption and that of minerals and other nutrients. Root hairs are delicate structures that can only survive for a couple of days. They do...
Plant Root Hair Tissue Specimen As a plant biologist, I have had the opportunity to study various plant tissues, including root hair tissue specimens. Root hair tissue is a crucial part of the plant's root system, as it plays a significant role in the absorption of water and nutrients from...
