Detailed explanation-1: -Plant cells are autotrophs which acquire nutrients and create energy from sunlight transforming light into glucose in their chloroplasts (speciallized plastids). Plants also have cell walls outside their membranes which provide a rigid frame for the cell.

Detailed explanation-2: -Multicellular Algae True multicellular forms are characterized by having separate cells, each with its own nucleus, plasma membrane, and cell wall. Streptophytes and many multicellular chlorophyte algae are organized in this manner.
