At a glance, leaves appear quite simple. However, their complex organic structure and the multiple processes that take place within them are astonishing. Leaves consist of millions of tiny cells that are shaped like balloons, which are known as chloroplasts. These chloroplasts are filled with a gel-like substance known as chlorophyll. Chlorophyll imparts a lovely green hue to the leaves. One of the main functions of leaves is the absorption of the carbon dioxide that plants need from the air. This gas is absorbed into the leaves through small openings known as the stomata. The cells in the leaves then convert the carbon dioxide into sugar molecules for the plant's use. For plants, oxygen is a waste product, so during the conversion the leaves will expire oxygen. Leaves constantly absorb sunlight, carbon dioxide and water from different sources to create food for the plant. This process is known as photosynthesis.

[1] nothing that comes from the desert expresses its extremes better than the unhappy growth of the tree yuccas. tormented, thin forests of it stalk drearily in the high mesas, particularly in that triangular slip that fans out eastward from the meeting of the sierras and coastwise hills. the yucca bristles with bayonet-pointed leaves, dull green, growing shaggy with age like an old [5] man's tangled gray beard, tipped with panicles of foul, greenish blooms. after its death, which is slow, the ghostly hollow network of its woody skeleton, with hardly power to rot, makes even the moonlight fearful. but it isn't always this way. before the yucca has come to flower, while yet its bloom is a luxurious, creamy, cone-shaped bud of the size of a small cabbage, full of sugary sap. the indians twist it deftly out of its fence of daggers and roast the prize for their [10] own delectation why does the author use the words "bayonet-pointed" (line 4) and "fence of daggers" (line 9) to describe the leaves of the yucca tree? . to create an image of the sharp edges of the plant to emphasize how beautiful the plant's leaves are to explain when and where the plant grows to show how afraid the author is of the plant
