    Above ground‚ shoot systems evolved. Their stems and leaves captured energy form the sun and carbon dioxide from the air. Stems became erect‚ taller‚ and branched when plants developed a capacity to make and incorporate lignin‚ a glue-like polymer‚ in their cell walls. Lignin-strengthened walls supported the stems as they grew upward and outward‚ in patterns that increased the light-intercepting surface of leaves. Vascular tissues‚ xylem and phloem‚ first appeared in plants called rhyniophytes

    i n f o a b s t r a c t Ethanol production from lignocellulosic materials is often conceived considering independent‚ standalone production plants; in the Brazilian scenario‚ where part of the potential feedstock (sugarcane bagasse) for second generation ethanol production is already available at conventional first generation production plants‚ an integrated first and second generation production process seems to be the most obvious option. In this study stand-alone second generation ethanol production

    xylem is a tubular shape that has no cross walls which allows a continuous column of water and minerals a more rapid transport within the xylem‚ there are two types protoxylem first formed xylem and metaxylem mature xylem which depends on pattern of lignin‚ the phloem is an elongated tubular shape with thin walled sieve tubes. The sieve tubes have pores at each end in the cross walls and microtubules that extend between sieve elements allowing longitudinal flow of material. Xylem sap contains water

    Evolution of land animals THE LARGEST genetic study ever performed to learn when land plants and fungi first appeared on the Earth has revealed a plausible biological cause for two major climate events: the Snowball Earth eras‚ when ice periodically covered the globe‚ and the era called the Cambrian Explosion‚ which produced the first fossils of almost all major categories of animals living today. According to the authors of the study‚ Science‚ plants paved the way for the evolution of land

    microscopy revealed characteristics features of C. spinosa. Preliminary phytochemical screening of flower buds of C. spinosa L. revealed the presence of alkaloids‚ reducing sugars‚ carbohydrates‚ saponins‚ phenolic compounds‚ tannins‚ anthraquinones and lignins in aqueous extract. The nutraceutical and chemical compositions exposed the presence of good measures of studied parameters. Strong anti-oxidant activity was noticed in aqueous extract based on the results of DPPH radical scavenging and lipid peroxidation

    soil biota that contributes to the decomposition of organic matter. Wood decomposition is also influenced by the fungal species that break it down. Some of these species form brown rot (where only cellulose and hemicellulose are broken down leaving lignin which is brown)‚ while others form white rot where all three are broken down). The majority of fungi are white rotters‚ but brown rot fungi are ecologically important because they form long-lived nurse
