From Quiz A Partridge in a Pear Tree

Answer: California

Its nickname is Methuselah and in 2012 was estimated to be 4843 years old. Pinus Longaeva, which is a bristlecone pine tree was estimated by experts to be the oldest tree in the world and is in the Californian Inyo National Forest. Its whereabouts are kept secret for fear of vandalism and disturbance of the ecosystem. Prior to Methuselah, another bristlecone pine tree named Prometheus, estimated to be in excess of 5000 years old, came to a tragic end in 1964 when a geography student named Donald Currey was given permission to cut down an old tree for his research. Unfortunately, he chose poor old Prometheus!

Answer: Poison hemlock

Poison hemlock thrives in damp ground and thus can often be found near streams or near roads. Although it is native to Europe it has found its way all around the world, and every part of it is toxic to humans to some degree when ingested. It should not be mistaken for water hemlock (cicuta), which, although similarly named, has different toxic components. Poison hemlock's main chemical, coniine, causes paralysis by acting on the brain and blocking neural pathways which trigger muscular movements. This can eventually affect and block the respiratory system and cardiac systems and become fatal - if we cannot breathe or circulate blood, we will die. However, if caught reasonably quickly, it can be treated by flushing the gastrointestinal system and administering activated charcoal. Socrates' famous poisoning is a well-known story. It is said that he, as a moral and social critic, disagreed with the Athenian political system at the time. He believed he was wiser than the general Athenian populace because he knew he was ignorant, and claimed they did not, which inspired their ire. For this and his beliefs on religion, he was tried and sentenced to death by majority vote. Although it is believed he could have escaped death, as his comrades could have broken him free, it is said he embraced it, freely drinking the concoction of poison hemlock that gradually numbed his body and sent him to the grave.

A caryopsis is a dry fruit (a fruit with a hard texture) that is indehiscent (fruit does not open when it matures) and is composed of a single carpel (female reproductive organ of the flower) in which the pericarp (tissue surrounding the seed) sticks tightly to the seed. Wheat and rice are other plants that have caryopsis fruits.

Answer: Baobab

The Baobab tree, Latin name Adansonia digitata, which is widely grown throughout many countries in Africa, is known as the "upside down tree" because of its strange way of growing. It is deciduous and when it is bare of leaves, the branches look like roots growing up in the air. The baobab produces fruits which contain an edible pulp known as monkey bread. The height of the Baobab ranges from 5 metres to 20 metres and the hollow trunks have been known to have been used as prisons, housing, storage barns, bus shelters and even "Loos with Views".

From Quiz Not Just For Decoration

Answer: Oleander

Despite its toxicity, this plant was, perhaps surprisingly, reported to be the cause of 'only' three human deaths between 1985 and 2005. Nonetheless, it can cause unpleasant symptoms such as vomiting, circulatory problems and irregular heartbeat. Plus, it is reported to have an acrid, unappealing taste, so it is not a gastronomic pleasure to consume. However, it's not all bad news - the plant has been considered for use in treating certain cardiac conditions such as atrial fibrillation, and it has been used as a folk medicine for many years. In addition, oleander can make an aesthetically appealing ornamental shrub, as long as it is handled with care.

From Quiz Redwood Adaptations

Answer: Fairy ring

Pretty cool, huh? When a redwood dies, (of natural or not so natural causes) the roots grow into new trees, creating what is dubbed a fairy ring around the site of the original tree. Visit a redwood forest sometime and check out these beautiful natural cathedrals. Redwoods also reproduce in other ways. They have seed-bearing cones like other coniferous trees. (hence the name CONiferous) Also, they can reproduce through burl. Burl is a growth on the side of a redwood tree that holds all of the 'blueprints', if you will, for a new tree. Tourist shops will sell burl that need only be placed in water to sprout. So you can have your own little redwood tree. These trees won't last very long in the wrong climate, though, so buyer beware.

From Quiz Not Just For Decoration

Answer: Ricin

The seeds of the castor oil plant contain most of its poison; however, it is also this seed which contains its highly useful oil. Unfortunately, compounds on the plant's surface can cause permanent nerve damage to the workers who handle these plants. One means of extracting the oil involves hulling (removing the outer covering) of the seeds, cooking them (which denatures the ricin) and then crushing and pressing them under high pressure and often low temperature. After this process, it can be utilised commercially. Ricin is highly toxic, but most humans will not chew their way into consuming the majority of the ricin, because the shells of the seeds are hard and indigestible, and it is those seeds which contain most of the poison. Ricin's toxicity comes from the fact that it inhibits protein synthesis. As proteins are involved in cell growth and repair, such inhibition kills cells. Whilst, for the above reasons, ricin is rarely fatal when ingested as a castor oil seed, it can still cause damage to the stomach and intestines, and can cause permanent damage to these and other organs. No antidote was found for ricin in the 20th century, meaning that simply avoiding it was the best treatment. After all, prevention is often better than the cure.
