Nutritional requirements The composition of medium for the tissue culture is the most important key factor in the successful culture of plant cells. The medium should be accurately defined of inorganic and organic chemical additives so as to provide i) the nutrients for the survival of the plant cells‚ tissues and organs under culture and ii) the optimal physical condition of pH‚ osmotic pressure‚ etc. In the culture of plant cells formulating optimum type of medium favorable for in vitro

curved‚ with a yellow‚ purple‚ or red rind covering soft starchy fruit (Merriam-Webster). Banana plants are often mistaken for trees‚ because their “false stem” or pseudostem resembles a tree trunk. However‚ trees are dicots with organized vascular bundles while banana plants are monocots‚ which have scattered vascular bundles. The average cultivated banana plant stands at 16 feet tall‚ although they may range from 10 to 23 feet (Nelson 26). A mature banana plant forms an inflorescence at the top of

this case density can effect growth and development‚ nutritional output‚ and overall structure of the plant (Casal‚ 1985). Observing the effect of density in mung bean plants (Vigna radiata) allows the effect to be seen occurring in dicot plant‚ rather than a monocot plant such as corn. Mung bean is most commonly used as a food source for the sprouts they produce. When grown as a crop‚ these plants can grow anywhere between twenty four and thirty inches tall‚ and they can flower after about fifty

Gene Cloning of Cucumber Mosaic Virus and Some Related Viral Agents 1.1 Introduction Cucumber mosaic virus (CMV) is a typical member of the genus Cucumovirus. It has infected more than 1‚000 species of monocots and dicots‚ including many economically important crops (Palukaitis and García-Arenal‚ 2003; Palukaitis et al.‚ 1992). In China‚ CMV is commonly detected as the principal virus infecting field crops in the families Solanaceae (including tobacco‚ tomato‚ potato‚ pepper‚ etc.)‚ Brassicaceae

Agrobacterium tumefaciens Agrobacterium tumefaciens (updated scientific name: Rhizobium radiobacter) is a gram-negative rod-shaped bacteria closely related to nitrogen-fixing bacteria which dwell at root nodules in legumes and unlike most other soil-dwelling bacteria‚ it infects the roots of plants to cause Crown Gall Disease of the family Rhizobiaceae‚ which includes the nitrogen fixing legume symbionts. Unlike the nitrogen fixing symbionts‚ tumor producing Agrobacterium are pathogenic and do

Abstract This lab activity aims to provide us a comprehensive familiarity with the proper use and handling of the optical microscope‚ which is a significant instrument in viewing‚ inspecting and studying the different parts‚ structures‚ and components of various botanical specimens. In this particular experiment‚ we will study the cross section of a monocot root. In the process‚ we will become familiar with the parts of the monocot root such as the stele

Respiration is gas exchange (Oxygen and Carbon Dioxide) with the external environment. All living things respire. Gas exchange is important so that cellular respiration can take place and energy can be made for the cells. 2.
