DENDROLOGY

Detailed explanation-1: -Protista. Protists are single-celled and usually move by cilia, flagella, or by amoeboid mechanisms. There is usually no cell wall, although some forms may have a cell wall.

Detailed explanation-2: -Animal cells are typical of the eukaryotic cell, enclosed by a plasma membrane and containing a membrane-bound nucleus and organelles. Unlike the eukaryotic cells of plants and fungi, animal cells do not have a cell wall.

Detailed explanation-3: -Unlike plants, those in the kingdom Animalia have no cell walls or chloroplasts. They are multicellular and heterotrophic and include sponges, worms, insects, fish, and mammals.

Detailed explanation-4: -Plant cells have a cell wall, as well as a cell membrane. In plants, the cell wall surrounds the cell membrane. This gives the plant cell its unique rectangular shape. Animal cells simply have a cell membrane, but no cell wall.
