It´s name is Audrey II and it appeared in the music film “Little shop of horrors”, directed by Franz Oz in 1986 adapting the film “The Little Shop of Horrors” directed by Roger Corman in 1960. Audrey II is a […]
Nitrogen (N) is an essential nutrient for plant growth and most plants require 20-50 g of N taken up by their roots to produce 1 kg of dry biomass. Although N is one of the most abundant elements on earth, agricultural soils are deficient in N and thus, to sustain crops productivity soils require their […]
Some plants have the capacity to develop tubers. Tubers are storage organs that serve as a survival strategy to better cope with adverse environmental conditions such as dry periods and cold. Tubers are sometimes also a means of asexual reproduction. In fact, tubers can persist in the soil during unfavorable conditions and generate a new […]
This article is focused on a recent paper [PDF] written by Jo Day from the Department of Classics of the University College Dublin exploring the links between botany and archaeology using case studies from ancient Mediterranean civilizations. Archaeology is more associated with the discovery of tombs and ancient human remains than with plants. However, the […]
Seed germination can be defined as the restart of growth of the embryo of the mature seed. Germination depends on the same environmental conditions as vegetative growth does, water and oxygen must be available, the temperature must be suitable and there must not be inhibitory substances present. However, it is common that even in favorable […]
18th of May is the “Fascination of Plants Day”. This is the second year that this initiative takes place. The “Fascination of Plants Day” is coordinated by the European Plant Science Organisation (EPSO), an independent academic organization that represents more than 226 research institutes, departments and universities from 30 countries. Many different activities are being […]
Carbohydrates are molecules composed of carbon, oxygen and hydrogen. They are formed of at least three atoms of carbon. Monosaccharides are the simplest carbohydrates and they cannot be hydrolyzed to smaller carbohydrates. Among the monosccharides we find glucose or fructoses which are formed of six atoms of carbon or glyceraldehyde which is composed of three […]
Flowers are the reproductive organs of angiosperms (flowering plants) and flowering is therefore the phenomenon by which the undifferentiated cells from the meristems (similar to animal stem cells) differentiate into a floral meristem that will then produce the different components of the flower (sepals, petals, stamens and carpels). This transition from a plant vegetative to […]
All of us know that animals use camouflage and mimicry as strategies to protect themselves from predators. Many examples have become famous with many TV documentaries showing, among others, foxes and rabbits that in higher latitudes are white to be confused with the snow and thus, to become harder to be distinguished and caught. Insects […]
Symbiosis is a close relationship between two organisms that benefits both of them. Many different types of symbiotic processes exist in nature, some of them are very famous like the symbiosis between clownfish (like Nemo from the film) with sea anemone or for example lichens which consist in a symbiotic relationship between a fungus and […]
