Final answer:
The statement is true. Plants are multicellular, eukaryotic organisms that perform photosynthesis and have evolved adaptations to live on land, including vascular tissues and reproductive structures.
Step-by-step explanation:
The statement is true: Plants are indeed multicellular, photosynthetic eukaryotes that have adapted to a land existence.
Plants, which perform photosynthesis, are multicellular organisms that evolved from freshwater green algae. Their cells are eukaryotic, containing a nucleus and various membrane-bound organelles such as chloroplasts.
Chloroplasts are essential for photosynthesis, the process by which plants use sunlight to convert carbon dioxide and water into glucose, which serves as their food. Unlike algae, which is mostly unicellular, all plants are multicellular.
Land adaptations in plants include features such as a protective cuticle to minimize water loss, stomata for gas exchange, and vascular tissues for transporting water and nutrients. Other key adaptations are the development of seeds, which protect and provide nourishment for the embryo, and flowers, which aid in reproduction. These adaptations have enabled plants to thrive on land across a variety of ecosystems, making them a pivotal component of life on Earth.
