Plants require water and nutrients to live. Most plants also require light, temperature, space, time, healthy soil and clean air. Plants perform chemical and physical processes similar to other living organisms that allow them to sustain life.Know More
Plants use a process called photosynthesis to create their own food. This process requires sunlight and a cell pigment called chlorophyll, which gives plants their green hue. A lack of adequate sunlight often causes plants to produce less fruits or flowers, and it can weaken the plant. Poor air quality can also prevent photosynthesis, as plants need to be able to take in carbon dioxide from the air to complete the photosynthesis process.
Plants require healthy soil in order to receive nutrients that are necessary for survival. The soil also keeps the plant firmly grounded. Providing fertilizer helps to keep plants healthy by providing additional nutrients not found in the soil. Nitrogen, phosphorous and potassium are the most essential nutrients required by the majority of plants.
Plants are affected by temperatures, and many plants die if subjected to extreme cold or hot temperatures. Plants require ample space to grow and live. If they are confined, plants are often subject to diseases due to a lack of proper airflow.Learn more about Botany
Plants that live in cold climates include saxifrages, willows and ranunculus. Other types of plants that do well in cold climates are pinks and whitlow-grass.Full Answer >
Tall and short varieties of grass and some flowering perennials dominate grasslands, including the prairies of North America. Big bluestem grass, blue grama grass, buffalo grass and Indian grass are abundant. Flowering perennials like milkweeds, goldenrods, asters, blazing star, sweet coneflower and purple coneflower bloom where rainfall is sufficient. These plants survive cold winters and fires in grasslands by developing underground storage organs and thick stem bases.Full Answer >
The different plant species that live in the ocean include phytoplankton, diatoms, dinoflagellates, sea-grasses, kelp and algae. These plants have special adaptation features that help them survive in the water.Full Answer >
Both floating and rooted plants grow in the ocean, but single-celled floating phytoplankton are the most common. Most of the ocean floor is covered in darkness, so rooted plants do not grow there.Full Answer >
