Facts About Leaves: Welcome to FactsCrush.Com. In this article we will know some facts related to Leaves. We have done a lot of research on this topic. We hope that you will definitely get the information you need related to Leaves here.

Leaf is the main lateral organ of the upper part of the plant whose main function is photosynthesis. A leaf is a part of a plant that has a constant volume. Leaf blades are generally flattened and thin to allow sunlight to pass through the cells and reach all the cells in the leaf that contain chloroplasts. Apart from this, physiological functions such as respiration, evaporation etc. are done in the leaves. Leaves can also serve as food and water reservoirs. In some plants, the shape of the leaves may change due to special needs. Also some plants have different colors due to weather conditions.

Fun Facts about Leaves for Kindergarten

  • In the winter months, plants and trees will be bare and have no leaves. There are exceptions, plants classified as evergreens contain leaves all year round.
  • In some plants, young leaves may be reddish, because they still have little chlorophyll. Growing, the leaves turn green, as they begin to produce more chlorophyll.
  • Veins, which can be seen in the thickness of the leaf, in their functionality are similar to blood vessels in the human body, only they do not carry blood, but water.
  • Sheaths are leaves that grow out from grass plants (Poaceae). An example of a grass plant is the common wheat (Triticum aestivum) and Kentucky blue grass (Poa pratensis).
  • Conifer are leaves that grow out from coniferous trees (Pinophyta). An example of a coniferous trees is the Atlas cedar (Cedrus atlantica) and the mountain pine (Pinus mugo).
  • The leaves of the aquatic common duckweed plant (Lemna minor) have some of the smallest leaves in the plant kingdom. Their leaves only reach a length between 0.04 and 0.4 inches.
  • Fronds are leaves that grow out from fern plants (Polypodiopsida). An example of fern plants is the royal fern (Osmunda regalis) and the western sword fern (Polystichum munitum).
  • They are mostly green in color. This is due to the presence of a compound called chlorophyll. This compound is essential for photosynthesis as it absorbs light energy from the sun.
  • Stipules (and lamina) are leaves that grow out from flowering plants (Angiospermae). An example of a flowering plant is the prairie rose (Rosa blanda) and the common daisy (Bellis perennis).
  • The needles of conifers and shrubs are also leaves, just such a peculiar shape. They live on average from 6 to 12 years with ordinary spruce, after which they die and are replaced by new ones.

  • Clovers feature alternate compound leaves, usually with three toothed leaflets. Clovers occasionally have four leaflets, instead of the usual three. These four-leaf clovers, like other rarities, are
  • For example, the Japanese Red Maple has red leaves. They’re red because they contain the red pigment anthocyanin. They do contain chlorophyll, but the higher levels of anthocyanin give the leaves a red hue.
  • Koalas, Greater Gliders and Ringtail Possums, are only mammals which can survive on a diet of eucalyptus leaves. Eucalyptus leaves are very fibrous and low in nutrition, and to most animals are extremely poisonous.
  • Leaves vary tremendously in shape and in size: from the tiny leaves (less than 1 millimeter across) of the floating aquatic plant duckweed to the giant leaves (25 m (82 ft) long and 3 m (9.8 ft) wide) of the raffia palm.
  • In Chile, a unique goblet plant grows, noteworthy in that it mimics other plants, along which the goblet’s shoots creep up to the sunlight. On one shoot of a goblet, leaves of different colors and different shapes can grow.
  • In the fall months, plants and trees start to absorb nutrients from their leaves in preparation for the winter months. Leaves will start to turn into many different colors, including but not limited to yellow, red and brown.
  • During the autumn, deciduous trees change color and then lose their leaves. This is in preparation for the winter season. Because it gets so cold, the trees have adapted to the winter by going into a period of dormancy or sleep.
  • It is claimed that there are approximately 10,000 three-leaf clovers for every four-leaf clover. However, an actual survey of over 5 million clovers found the real frequency to be closer to 5,000 to 1, twice the said probability.
  • Tea is an aromatic beverage commonly prepared by pouring hot or boiling water over cured leaves of the Camellia sinensis, an evergreen shrub (bush) native to East Asia. After water, it is the most widely consumed drink in the world.
  • In the world there is such an amazing long-lived plant as velveteen. It can live up to hundreds of years, while it has only two sheets, with which velveteen is inextricably linked. If the leaves are damaged, the plant will inevitably die.
  • Clovers can also have five, six, or more leaflets, but these are rarer still. The record for most leaflets is 56, set on 10 May 2009. This beat the “21-leaf clover”, a record set in June 2008 by the same discoverer, who had also held the prior Guinness World Record of 18.
  • Certain organs that are superficially very different from the usual green leaf are formed in the same manner and are actually modified leaves – among these are the sharp spines of cacti, the needles of pines and other conifers, and the scales of an asparagus stalk or a lily bulb.
  • Without leaves there would be no trees, and without trees there would be no oxygen, which means there would be no life on Earth in its usual form. Some trees get rid of leaves for the cold, or, conversely, arid and hot seasons, to reduce the costs of nutrients to maintain them, while others keep them year-round.
  • The longest-lived leaves of all plants belong to the welwitschia, named after botanist, Dr Friedrich Welwitsch (Austria), who discovered the plant (looking like a “stranded octopus”) in 1859 in its native Namib Desert of Namibia and Angola. The welwitschia has an estimated lifespan of between 400 and 1,500 years, with some specimens carbon-dated to 2,000 years old. Each plant produces two leaves per century, and never sheds them. Ancient individuals sprawl out over 10 m (33 ft) in circumference, with enough foliage to cover a 400-m (1,312-ft) athletic field.
