Colton Ramstrom Mrs. Fulton Intro to Botany 4/11/12 Oddities of Kingdom Plantae Through evolution plants have acquired complex and unique characteristics. Some of these characteristics may be deemed bizarre. Plants have come a long way since their shift to terrestrial habitats from aquatic habitats millions of years ago. From the development of the cuticle to prevent water loss to the evolution of vascular tissues to provide for efficient internal transportation‚ all evolutionary changes took

Imagine a world without crops like apples‚ coffee‚ broccoli‚ and cocoa. We consume these products often‚ and just expect them to always be around. A world without bees is a world without these crops and many‚ many more because they are our main pollinators. When people eat a meal‚ not much thought goes into how that food is produced. Bees play a part in the production of one-third of all the food we eat. The harsh reality is that honey bees are dying and rapidly. Researchers have been scrambling

When the bee visits the next flower‚ some of this pollen is rubbed off onto the stigma‚ or tip of the pistil- the female reproductive organ of the flower. When this happens‚ fertilization is possible‚ and a fruit‚ carrying seeds‚ can develop (Pollination). Pesticides also stick to the bees hairs which results in it spreading to other plants‚ including wild plants. Once in the soil‚ pesticides leach into the water system

Environmental News Article 2 According to the article “A Bumblebee Gets New Protection on Obama’s Way Out‚” rusty-patched bumblebees‚ which were once prevalent across the United States‚ have now been put on the endangered species list (Schlossberg and Schwartz 2017). The population of these rusty-patched bumblebees has declined roughly ninety percent since the 1990s‚ as a result from pesticide exposure‚ climate change‚ disease‚ and habitat loss. Once common across twenty eight states‚ the District

include species like Oncidium‚ Maxillaria etc. These are native species found abundantly in Costa Rica. Ultimately‚ hybrid species are found profusely in the last phase of exploration. These are scientifically produced species in labs by cross pollination and under a controlled environment‚ hence‚ resulting in wonderful new combinations. This short tour through the wonderful jungle filled with orchids is a never forgetting experience and a golden jewel in memory

reproductive tissues of the parental sporophyte generation. Nutrient exchange also occurs between gametophytes and their parents. In contrast‚ the free-living gametophytes of seedless vascular plants must fend for themselves. In gymnosperms‚ pollination is the transfer of pollen (Fig. 2) from male cones (where pollen is produced) to female cones‚ which house eggs. In these plants‚ pollen is carried from male cones to female cones by wind - gymnosperms were the first plants to evolve that did not

Research paper: Honey Bees’ disappearance Bees are flying insects that are related to wasps and ants. Those insects are mostly known for their role of pollination and for producing honey and beeswax. There are about 20‚000 different species of bees around the world‚ and every single species of bees live in colonies where there are three types of bees: the queen‚ the worker‚ and the drone. However‚ a lot of scientists and beekeepers noticed since 2006 that the population of bees in world started

China pollinates by hand now A third of global farm output depends on animal pollination‚ largely by honey bees. These foods provide 35pc of our calories‚ most of our minerals‚ vitamins‚ and anti-oxidants‚ and the foundations of gastronomy. Yet the bees are dying – or being killed – at a disturbing pace.

Colony Collapse Disorder is the phenomenon that occurs when the majority of worker bees in a colony disappear and leave behind a queen. The crazy part of this is that there is plenty of food and a few nurse bees left to care for the remaining immature bees and the queen. There has been theory upon theory of why this is happening but no one has the for sure answer. You may be asking why is this such a big deal?! Well CCD (Colony Collapse Disorder) causes significant economic losses because many agricultural
