Question: Not all cells in a multicellular plant contain chloroplasts. All green parts of a plant contain chloroplasts—the chloroplasts, or more specifically, the chlorophyll in them are what make the photosynthetic parts of a plant green. The plant cells which contain chloroplasts are usually parenchyma cells, though chloroplasts can also be found in collenchyma tissue. A plant cell which contains chloroplasts is known as a chlorenchyma cell. A typical chlorenchyma cell of a land plant contains about 10 to 100 chloroplasts.

Answer: What parts of plants have chloroplasts?


Question: Since the Peace of Westphalia, the Upper Rhine formed a contentious border between France and Germany. Establishing "natural borders" on the Rhine was a long-term goal of French foreign policy, since the Middle Ages, though the language border was – and is – far more to the west. French leaders, such as Louis XIV and Napoleon Bonaparte, tried with varying degrees of success to annex lands west of the Rhine. The Confederation of the Rhine was established by Napoleon, as a French client state, in 1806 and lasted until 1814, during which time it served as a significant source of resources and military manpower for the First French Empire. In 1840, the Rhine crisis, prompted by French prime minister Adolphe Thiers's desire to reinstate the Rhine as a natural border, led to a diplomatic crisis and a wave of nationalism in Germany.

Answer: What was the name of the time the Upper Rhine form a border between France and Germany?


Question: Doctor Who originally ran for 26 seasons on BBC One, from 23 November 1963 until 6 December 1989. During the original run, each weekly episode formed part of a story (or "serial") — usually of four to six parts in earlier years and three to four in later years. Notable exceptions were: The Daleks' Master Plan, which aired in 12 episodes (plus an earlier one-episode teaser, "Mission to the Unknown", featuring none of the regular cast); almost an entire season of seven-episode serials (season 7); the 10-episode serial The War Games; and The Trial of a Time Lord, which ran for 14 episodes (albeit divided into three production codes and four narrative segments) during season 23. Occasionally serials were loosely connected by a storyline, such as season 8 being devoted to the Doctor battling a rogue Time Lord called The Master, season 16's quest for The Key to Time, season 18's journey through E-Space and the theme of entropy, and season 20's Black Guardian Trilogy.

Answer:
How many seasons did the original Doctor Who run?
