Passage 1

What is commonly called pepper in reality comes from two very different families of plants. Black and white pepper both come from the fruit of the piper nigrum, a vine with fruits called peppercorns. The peppercorns turn from green to red as they ripen and finally blacken as they dry out. The dried-out peppercorns are ground to obtain black pepper. White pepper, which has a more subtle flavor than black pepper, comes from the same peppercorns as black pepper; to obtain white pepper, the outer hull of the peppercorn, the pericarp, is removed before the peppercorn is ground. Red and green peppers, on the other hand, come from a completely different family from black and white pepper. Red and green peppers are from the genus Capsicum. Plants of this type generally have tiny white flowers and fruit which can be any one of a number of colors, shapes, and size. These peppers range in flavor from very mild and sweet to the most incredibly burning taste imaginable. Bell peppers are the most mild, while habaneras are the most burning. Christopher Columbus is responsible for the present-day confusion over what a pepper is. The piper nigrum variety of pepper was highly valued for centuries, and high demand for pepper by Europeans was a major cause of the fifteenth-century push to locate ocean routes to the spice-growing regions of Asia.When Columbus arrived in the New World in 1492, he was particularly interested in finding black pepper because of the high price that it would command in Europe. Columbus came across plants from the Capsicum family in use among the people of the New York World and he incorrectly identified them as relatives of black pepper. Columbus introduced the spicy Capsicum chili peppers to Europeans on his return from the 1492 voyage, and traders later spread them to Asia and Africa. These Capsicum peppers have continued to be called peppers in spite of the fact that they are not related to the black and white pepper of the Piper nigrum family.

Algae is a primitive form of life, a single-celled or simple multiple-celled organism that is able to conduct the process of photosynthesis. It is generally found in water but can also be found elsewhere, growing on such surfaces as rocks or trees. The various types of algae are classified according to their pigmentation

, or coloration Blue-green algae, or cyanophyta, can grow at very high temperatures and under- high intensity light. 

This is a microscopic type of algae, and some species consist of only one cell. Blue- green algae is the oldest form of life with photosynthetic capabilities, and fossilized remains of this type of algae more than 3.4 billion years old have been found in parts of Africa.

Green alga, or Chlorophyta, is generally found in freshwater. It reproduces on the surfaces of enclosed bodies of water such as ponds or lakes and has the appearance of a fuzzy green coating  on the water. In large quantities, this type of algae may reproduce enough to give a green color to an entire lake. 

Brown alga, or Phaeophyta, grows in shallow, temperate water. This type of algae is the largest in size and is most recognizable as a type of seaweed; kelp is a type of brown algae that has grown to lengths of up to 200 feet. Its long stalks can be enmeshed on the ocean floor, or it can float freely on the ocean's surface.

Passage 2

Algae is a primitive form of life, a single-celled or simple multiple-celled organism that is able to conduct the process of photosynthesis. It is generally found in water but can also be found elsewhere, growing on such surfaces as rocks or trees. The various types of algae are classified according to their pigmentation

, or coloration Blue-green algae, or cyanophyta, can grow at very high temperatures and under- high intensity light. 

This is a microscopic type of algae, and some species consist of only one cell. Blue- green algae is the oldest form of life with photosynthetic capabilities, and fossilized remains of this type of algae more than 3.4 billion years old have been found in parts of Africa.

Green alga, or Chlorophyta, is generally found in freshwater. It reproduces on the surfaces of enclosed bodies of water such as ponds or lakes and has the appearance of a fuzzy green coating  on the water. In large quantities, this type of algae may reproduce enough to give a green color to an entire lake. 

Brown alga, or Phaeophyta, grows in shallow, temperate water. This type of algae is the largest in size and is most recognizable as a type of seaweed; kelp is a type of brown algae that has grown to lengths of up to 200 feet. Its long stalks can be enmeshed on the ocean floor, or it can float freely on the ocean's surface.
