little or no cuticle (offering minimum resistance for oxygen diffusion) and dense cytoplasm studded with mitochondria at Ule tip of the root hairs, are some of the special ultrastructural adaptations of root hairs which offer an indication that at least one of their main functions involves ...
Why is active transport necessary in root hair cells? What are the adaptations of a root hair cell? Explain how water is absorbed by root hair cells. How do root cells get energy? Why is it important for cells to be able to use both active and passive transport to transport molecules ac...
How does the root hair cell have a role in the photosynthesis and gas exchange of an autotroph?Question:How does the root hair cell have a role in the photosynthesis and gas exchange of an autotroph?ROOT HAIR CELL:Root hairs are the outgrowths of epidermal ...
Roots are one of the earliest adaptations that enabled plants to colonize land (Kenrick & Crane, 1997). They perform essential functions necessary for the survival and development of plants, such as anchoring them to a substrate, providing mechanical support, storingphotoassimilates, and absorbing ...
How did the concept evolve with newly added traits and related functions? Where can the RES enhance our understanding of plant and ecosystem functioning? Support for the root economics space: a literature review To examine the present state of knowledge around the RES, we reviewed the literature ...
(such as nitrogen fixing bacteria and mycorrhizal fungi) to aid them in their quest for nutrients. Finally, some key biotic and abiotic constraints on root development and function in the soil environment are examined and some of the adaptations roots have evolved to counter such stresses ...

3. Root system development Root development can be divided in two main stages: a) embryonic development (ED) and b) post-embryonic development (PED). During the ED, through a suite of highly regulated and reproducible stages, the fertilized egg cell rises into an embryo. In the embryo, ...
Environmental stresses as major threats to global food security in the twenty-first century and improving biomass production and seed yield per area of crop plants become very critical. Plants are sessile organisms that cannot escape from environmental c
3. Lifestyle adaptations of Rhizobium from rhizosphere to symbiosis. Insertion sequencing was used to establish the role of Rhizobium leguminosarum bv. viciae 3841 (Rlv3841) genes at multiple stages of symbiosis with Pisum sativum. A. Rlv3841 transposon library was inocu- lated onto a...
