Chlorophyll absorbs light most effectively in the red and blue-purple regions but absorbs very little green light. As a result, green light is reflected back, and that\u2019s why we see leaves as green. According to the theory of light spectra, the light we see coming from the leaves is light that has been reflected, not absorbed. The other colors, like red and blue, are absorbed by chlorophyll, while green light is reflected and thus seen by our eyes.<\/span><\/i><\/p>\n<h4><b>V\u1eady t\u1ea1i sao m\u1ed9t s\u1ed1 c\u00e2y l\u1ea1i c\u00f3 l\u00e1 m\u00e0u \u0111\u1ecf, n\u00e2u ho\u1eb7c th\u1eadm ch\u00ed l\u00e0 v\u00e0ng?

Red leaves are primarily due to the presence of anthocyanin, a compound that creates red colors in plants. When the amount of anthocyanin in the leaf increases, it overpowers the green chlorophyll, causing the leaf to appear red.<\/span><\/p>\n<p><span style=\"font-weight: 400\">\u0110i\u1ec1u th\u00fa v\u1ecb l\u00e0 antocyan l\u00e0 m\u1ed9t h\u1ee3p ch\u1ea5t r\u1ea5t d\u1ec5 tan trong n\u01b0\u1edbc n\u00f3ng.

A simple experiment can demonstrate this: if you place a red leaf in hot water, you will see the red color gradually disappear and the leaf will change to green. This shows that although the leaf is red, it still contains chlorophyll, but because anthocyanin dominates, the red color becomes the main color.<\/span><\/p>\n<p><a href=\"https:\/\/i-clc.edu.vn\/wp-content\/uploads\/2024\/11\/hai-duong.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-20220 aligncenter\" src=\"https:\/\/i-clc.edu.vn\/wp-content\/uploads\/2024\/11\/hai-duong.jpg\" alt=\"\" width=\"554\" height=\"554\" \/><\/a><\/p>\n<p><b>Di\u1ec7p L\u1ee5c v\u00e0 S\u1ef1 Thay \u0110\u1ed5i M\u00e0u L\u00e1 V\u00e0o M\u00f9a Thu<\/b><\/p>\n<p><b><i>Chlorophyll and the Changing Colors of Leaves in Fall<\/i><\/b><\/p>\n<p><span style=\"font-weight: 400\">L\u1ee5c l\u1ea1p trong l\u00e1 c\u00e2y c\u0169ng gi\u1ed1ng nh\u01b0 nh\u1eefng &#8220;c\u1ed7 m\u00e1y&#8221; thu nh\u1ecf \u0111\u1ec3 h\u1ea5p th\u1ee5 n\u0103ng l\u01b0\u1ee3ng m\u1eb7t tr\u1eddi, nh\u01b0ng sau m\u1ed9t th\u1eddi gian ho\u1ea1t \u0111\u1ed9ng, ch\u00fang s\u1ebd tr\u1edf n\u00ean c\u0169 k\u1ef9 v\u00e0 \u0111\u01b0\u1ee3c thay th\u1ebf.

Then, other substances in the leaves are also reclaimed, and by the end of autumn, the leaves turn brown before falling off. The brown color of the fallen leaves may be a mix of the remaining colors in the leaf.<\/span><\/i><\/p>\n<p><a href=\"https:\/\/i-clc.edu.vn\/wp-content\/uploads\/2024\/11\/la-phong-do-4.jpg\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-20219 aligncenter\" src=\"https:\/\/i-clc.edu.vn\/wp-content\/uploads\/2024\/11\/la-phong-do-4.jpg\" alt=\"\" width=\"800\" height=\"600\" \/><\/a><\/p>\n<p><span style=\"font-weight: 400\">D\u00f9 l\u00e1 c\u00e2y c\u00f3 m\u00e0u xanh hay \u0111\u1ecf, t\u1ea5t c\u1ea3 c\u00e1c lo\u00e0i c\u00e2y \u0111\u1ec1u d\u00f9ng l\u00e1 \u0111\u1ec3 th\u1ef1c hi\u1ec7n qu\u00e1 tr\u00ecnh quang h\u1ee3p v\u00e0 trao \u0111\u1ed5i ch\u1ea5t, gi\u00fap c\u00e2y ph\u00e1t tri\u1ec3n m\u1ea1nh m\u1ebd v\u00e0 kh\u1ecfe kho\u1eafn.
