Labeled Plant Cell With Diagrams

Plant cells contain many organelles such as ribosomes, the nucleus, the plasma membrane, the cell wall, mitochondria, and chloroplasts. In addition, plant cells differ from animal cells in a number of key ways. Examining a diagram of the plant cell will help make the differences clearer. Let’s go over the individual components of plant cells

Photosynthesis Diagram: From Beginning To End

Photosynthesis is the process that allows plants to gather energy from the sun and transform it into energy they can use. How exactly does the process of photosynthesis work? Creating a model of a cell or examining a diagram can help you understand the process of photosynthesis. The diagram found above will give you some

Hooray For Social Diversification

Multiunit systems rely on the capacity to socially interact. For example, multicellular organisms, such as ourselves, comprise differentiated tissues that are composed of tens of billions of cells, which all have the capacity to communicate and cooperatively interact with one another, sometimes leading to a strong division of labor and interdependence. Sometimes, mutant cells may

Strange Dracula Wasp With Large Mandibles in Fossil Amber From Myanmar From Ca. 99 Mio. Years Ago Shows Features of Different Wasp Families, Questioning Current Delimitation of Taxa

Once more, an unexpected fossil insect has been discovered in fossil amber from Myanmar — commonly called Burmese amber. The wasp, which now was described as Supraserphites draculi gen. sp. nov. (see Fig. 1), shows characteristics of two different families, Serphitidae and Archaeoserphitidae. Because of several characteristics common with Serphitidae, the new genus has been placed

Devonian World Revealed

Perhaps it is Facebook or perhaps it is our current political moment, but it seems more apparent than ever that we live in intellectual silos, partly inherited from our upbringing, but also actively maintained within our tribes. Science is not immune to this tendency, as is most apparent from the two tribes of America land-grant,

How Chemical Compounds Affect Fruit Bats’ Plant Interactions

Fruit bats are known to be able to discriminate, select, and track the essential oils of their preferred fruits. A few years ago, our research group hypothesized, experimented, and confirmed that these bats can be attracted with essential oils only – concentrated volatile aromas – of their preferred fruits both in forested and open areas.

Acid Mine Drainage: A Huge Problem Around Abandoned Mines

Acid mine drainage (AMD) is an acidic mineral solution that flows out of a mine. The phenomenon in question is spontaneous and involves metal sulfides (type “M” Sx) with no economic value in mining. Indeed, during mining work (excavations and pumping), the chemical balance of these outcrops and deep deposits are disturbed by sudden changes

Are Hibernators Zombies? Not Genetically Speaking…

Consistent genetic and epigenetic regulation is required to sustain the complex homeostasis that is life, and it seems that a degree of this regulation continues into death. Recent post-mortem studies have identified a subset of genes that appear to come alive hours and days after organismal death; these so-called “zombie genes” have been implicated in

Forest “Hotspots” Of High Conservation Interest – Using The Past As A Guide For Management

The past can leave significant and surprising legacies Preserving large connected areas of valuable vegetation types in their natural, or essentially unmodified state, is a complex challenge for planning authorities at a time of rapidly changing climate. Palaeoecological data can shed light on past legacies from previous generations of trees that have influenced forest continuity,
