True grasses all belong to the Poaceae family of plants.There are approximately 10,000 species of grasses that belong to the Poaceae family. It has been found that grass is the most widely found species of plant life, as different types of grasses can be found in all habitats and climates.Grass species are known for having the largest variety among all plants on our planet. This mostly happens due to the ability of grass to adapt to its changing habitat and its structure helps it to grow faster and spread over a large area.Grass usually has a hollow stem between its joints and blade-like leaves. Grasses have an intricate root system where roots are fibrous and branch out in several directions in order to find any nutrients present in the soil. Grass is the basic food for many animals, especially herbivores.Grass also provides shelter for many animals and birds, and tough grass-like giant bamboo is used in construction materials and furniture. Many people grow grass on an expensive lawn as grass can also be grown ornamentally, and it also helps to prevent erosion.Grass helps in improving air quality by absorbing carbon dioxide and releasing oxygen. Oxygen is produced as a by-product of the photosynthesis process which helps grass grow.The reason behind your lawn grass appearing green in color is the presence of chlorophyll which is a pigment that absorbs blue and red light but reflects green light.Did you know that the largest species in the grass family is giant bamboo which can attain average heights of 98 ft (29.6 m)?Read on to know more facts about lawn grass and the Poaceae family. Afterward, also check out Suriname fun facts and creepy but true facts.Grass ClassificationGrass belongs to the Poaceae family, which includes all plants which are recognized for being short, in various shades of green, and without any wood.The grass family also comes under the Gramineae family much like Poaceae family, which is a family of monocotyledonous flowering plants. This grass family includes various grasses like giant bamboo and all species of bamboo, cereal grasses like oats, barley, and more.All grass species are found in grasslands around the world as well as domesticated or cultivated grass species used for pastures or decorating a perfect lawn.Grass species of the Poaceae family are the fifth largest in quantity among all the other plant families, with about 780 genera and more than 12,000 species. All lawn grasses have an adaptation wherein the leaf of the grass grows from the base of the blade, which allows it to grow even after being grazed frequently by animals.Significance Of Grass In The EcosystemGrass is said to be one of the major ecosystems in the world which covers almost one-third of the terrestrial surface of the Earth.Grass can be found almost everywhere, with huge grasslands in the middle of most continents of the world, like pampas in South America, prairies in North America, steppes in Eurasia, and the veld in Africa.Most grasses are food for animals, but there are several varieties of grass that form cereals, legumes, shrubs, and even trees in some species.Surprisingly, out of 15 major crops found all around the world which form a staple in many countries and help humans survive, 10 of them are grasses.Due to their ability to adapt to any climate they grow in, grass species are found in most environmental habitats like hot tropical zones near the equator and deserts to the coldest regions in Siberia, as well as in saltwater and freshwater aquatic habitats.Grass plays a very significant role in the ecosystem because it is an extremely important source of food for most herbivorous animals as well as for birds and insects, both in the wild as well as domesticated ones. Grass also plays an important part in the human diet, as more than 70% of the agricultural land around the world cultivates grass crops.Grasses produce edible grains, which are used as cereals in our diet and form almost 50% of the world’s calories. These cereals are a rich source of carbohydrates and are harvested all over the world. Many of these grass crops were only wild grass in the past, like corn and rice, but have now been domesticated and cultivated by humans to suit their palate.Many members of the grass family are also used as building materials but the most popular ones are straw and bamboo.Types Of GrassDue to the huge diversity found in the grass family, there are thousands of various species of grass from the Poaceae family all around the world. Most of the grass found in grasslands is classified by its height.Grass generally grows in tropical grasslands which are called savannas, and grasses which grow in temperate regions are known as prairies or steppes. One can find various grasses at almost every temperature and precipitation range.Types of giant grass include giant bamboo, while there are several varieties of short grasses which are found in different types of climates. Switchgrass grows up to 7 ft (2.13 m) in height, which is a variety of tall grasses. It can be found in prairies with ample sunlight and moist soil. Switchgrass also has a very high drought tolerance which allows it to grow in less moisture.Blue gamma grass is one of the grasses most fed on by wildlife animals. This grass is found in steppe grasslands. This grass grows throughout the year and can grow amply in low organic soils like gravel and sandy loams.Rhodes grass can reach up to 5 ft (1.5 m) in height and is mainly found in savanna grasslands. This grass can survive in areas with very little rainfall and warm temperatures, making it resistant to harsh climate and drought.Did you know that various varieties of grass grow across all continents, even in polar regions?Grasses for pastures and lawns are divided into categories like warm-season grasses and cool-season grasses. Warm-season grasses include Bermuda grass which has pointy leaves in shades of dark green. This grass is generally grown to achieve a dense, grassy lawn. Another one is St. Augustine grass which has soft round ends and coarse leaves. It grows very slowly and is extremely resilient to heat. This grass needs to be watered often to achieve a healthy lawn.Cool-season grasses are found in the northern parts of the USA and Canada, where these grasses tend to survive in colder climates and dry weather. One of the most popular grasses grown on lawns is the Kentucky bluegrass. This grass often is very dense and beautiful, giving you a properly covered, perfect lawn to walk on to enjoy an improved air quality.Long blades of this grass are resilient to lawnmowers and any foot traffic which may occur, so it is also termed as self-repairing grass. Another type of cool-season grass is fine fescue grass, which has thin, pointed leaves. This grass can grow well in fluctuating amounts of sunlight and temperature changes. This grass is often mixed with bluegrass to create the perfect lawn cover which feels soft and looks bright green.Does cutting grass make it spread?Yes, mowing your lawn or cutting the grass regularly makes the grass spread more effectively and cover any patchy areas in the ground.This happens mainly because grass usually grows from the tip of each blade, where a hormone is secreted which suppresses any horizontal growth. Hence, cutting this part allows the grass to spread everywhere by growing thicker.While mowing your lawn, there are certain things that you must keep in mind so as to not destroy your carefully pruned grass lawns. Only one-third of the top half of the grass should be cut as cutting more than necessary might give rise to other weeds which compete for nutrients with the grass.This helps maintain the balance which grasses have between their blades and their root systems which provide the grass stalk with strength and help it to cope with drought and environmental changes.Here at Kidadl, we have carefully created lots of interesting family-friendly facts for everyone to enjoy!
