Final answer:
All plant species have a common structure consisting of stems, roots, and leaves, a cell wall made of cellulose, and the ability to perform photosynthesis using chloroplasts. They require light, water, carbon dioxide, and soil nutrients to carry out photosynthesis, grow, and support ecosystems as primary producers.
Step-by-step explanation:
Characteristics Common to All Plant Species
There are specific characteristics that all species belonging to the plant kingdom share. First, each plant species consists of the basic structure that includes stems, roots, and leaves. These structures facilitate the transport of water, minerals, and sugars that are produced through photosynthesis. Additionally, all plant species respond similarly to environmental factors such as light, gravity, competition, temperature, and predation.
Secondly, plants are characterized by the presence of a cell wall made of cellulose which provides additional support and protection. Lastly, the ability to conduct photosynthesis is an essential characteristic of plants. This process occurs in specialized organelles called chloroplasts, which contain the pigment chlorophyll. Photosynthesis allows plants to convert light energy into chemical energy, which is stored as sugars and used for growth and development.
Requirement of Plants and Their Role in Ecosystems
Plants require certain key elements to thrive, such as light, water, carbon dioxide, and nutrients from the soil. These items are crucial because they are used in photosynthesis and for maintaining plant cell structure and function. Furthermore, plants play a vital role in ecosystems as producers, forming the base of the food chain and supporting life for a variety of organisms, including humans.
