NEET BIOLOGY

Detailed explanation-1: -The main reason is that they contain chloroplasts and produce food through photosynthesis. However, they lack many other structures of true plants. For example, algae do n ot have roots, stems, or leaves. Some algae also differ from plants in being motile.

Detailed explanation-2: -One of the main characteristics that differentiates macroalgae from plants is their structure. They may appear similar, but the macroalgae do not have specialized organs and tissues, and they are not vascularized. They also do not have the capacity to form a structure with flowers, leaves, roots or a stem.

Detailed explanation-3: -Algae, along with plants and some bacteria and fungi, are autotrophs. Autotrophs are the producers in the food chain, meaning they create their own nutrients and energy. Kelp, like most autotrophs, creates energy through a process called photosynthesis.

Detailed explanation-4: -Why are algae considered plant-like? The main reason is that they contain chloroplasts and produce food through photosynthesis.

Detailed explanation-5: -Most plants also have vascular structures (xylem and phloem), which carry nutrients throughout the plant. While algae contain chlorophyll (like plants), they do not have these specialized structures 8. Algae are sometimes considered protists, while other times they are classified as plants or choromists.
