Why do you need plants?
Plants are the backbone of life on earth. They provide us with the air we breathe, the food we eat, and the materials we use for shelter and clothing. plants provide us with fuel. Plants maintain the soil quality as when they die and decompose, they fertilise the soil, enabling other plants to grow and thrive. Plants keep the soil together preventing erosion. plants provide oxygen for us and all the other animals.Lines on Plants in English Plants are living organisms found everywhere on earth. They need sunlight, water, and air to grow healthy. Plants make their own food with sunlight (photosynthesis). They give us oxygen to breathe and take in carbon dioxide.Plants have basic needs. Plants need sunlight, water, air and nutrients from soil. Plants can survive and grow only when all their needs are met.Plants are a kingdom of life forms that includes familiar organisms such as trees, herbs, bushes, grasses, vines, ferns and mosses. Through photosynthesis, they convert water and carbon dioxide into the oxygen we breathe and the sugars that provide the primary fuel for life.Plants are essential for our survival. They provide food, fiber, building material, fuel, and pharmaceuticals. Plants also produce intangible benefits for people, such as improving our health.
What are the needs of a plant?
Plants have specific needs – light, air, water, nutrients, and space – to survive and reproduce. Without plants, animals would have no oxygen to breathe and would die. People also depend on plants for food. All animals eat either plants or plant-eating animals. Without plants there would be no food to eat!Oxygen on Earth without plants would last for 5000 years. Of course, life on the Earth can’t survive without the plants, but not because we would suffocate. We would die of hunger.Sunlight, water, air, habitat, and food are the basic needs of all living things. Without one or more of these living things will not be able to survive. These needs also extend to humans; without these five essential resources, we would perish.Without plants there wouldn’t be enough oxygen in the air to allow animals like humans to exist! We think plants evolved long before humans or large animals did, and they played a big role in changing the amounts of gases in the air. We also need plants for food.
Do we really need plants?
In the process of food production, plants release oxygen. No animal can do that. Plants not only make their own food, they also make food for us. The basic food for all organisms is produced by plants. Plants provide many useful things for humans including fruits and vegetables which we eat, wood for building, flowers for beauty, oils and perfumes, cotton for clothing, paper and medicines from plant materials, rubber and gum from plant saps, oxygen from photosynthesis, and shade from trees.They provide us with the air we breathe, the food we eat, and the materials we use for shelter and clothing. Here are some key reasons why plants are essential: Oxygen: Through the process of photosynthesis, plants release oxygen into the atmosphere, supporting the respiration of all living organisms, including humans.For starters, plants provide us with food and oxygen. They belong to a group of organisms that can produce their own food (autotrophs) through a process called photosynthesis, and since they also produce the food for most animals, including humans, they are the basis (producers) for all terrestrial ecosystems (Figure.The main function of leaves is to absorb light so plants can make food. Depending on their habitat, plants may have leaves of different sizes, shapes, textures, and colors.
What are the 6 needs of plants?
Plants need thirteen different nutrients from the soil in order to fully develop. Six of these nutrients are needed in large quantities. These six essential nutrients are nitrogen, phosphorus, potassium, magnesium, sulfur and calcium. Soil is a major source of nutrients needed by plants for growth. The three main nutrients are nitrogen (N), phosphorus (P) and potassium (K). Together they make up the trio known as NPK. Other important nutrients are calcium, magnesium and sulfur.
What are the 5 importance of plants?
Plants are essential for humans because they provide oxygen through the process of photosynthesis, supply food, medicine, raw materials for industry, and maintain environmental balance. They support life by offering shelter, improving soil quality, and regulating climate. Trees and shrubs improve soil and water conservation, store carbon, moderate local climate by providing shade, regulate temperature extremes, increase wildlife habitat and improve the land’s capacity to adapt to climate change. These are all benefits forests and shrubs offer the environment and in turn, us.Trees contribute to their environment over long periods of time by improving air quality, climate amelioration, conserving water, preserving soil, and supporting wildlife. During the process of photosynthesis, trees take in carbon dioxide and produce oxygen.
What do plants need to grow grade 5?
They need sunshine, water, and air to grow. They are not able to move around. Their cells have stiff walls made of a tough material called cellulose. All green plants use the Sun’s energy, water, and a gas called carbon dioxide to make their own food. Plants need air, light, warmth, water and nutrients to be healthy. If a plant doesn’t have one of these requirements it could affect its growth or even die.Like a human, your indoor plant has a number of basic needs to survive and grow. In addition to food, these are light, water, carbon dioxide, temperature and humidity.Plants have three main features: they are eukaryotic, photosynthetic, and multicellular. Plants capture the energy of sunlight and use carbon dioxide to make their own food through photosynthesis. Plants must be multicellular and composed of more than one cell.Plants are the eukaryotes that comprise the kingdom Plantae; they are predominantly photosynthetic. This means that they obtain their energy from sunlight, using chloroplasts derived from endosymbiosis with cyanobacteria to produce sugars from carbon dioxide and water, using the green pigment chlorophyll.Plants have specific needs – light, air, water, nutrients, and space – to survive and reproduce. Almost all plants need these five things to survive: Light.
