Diversity in Living Organisms

Kingdom Animalia consists of multicellular, eukaryotic, heterotrophic organisms that lack a cell wall and typically exhibit complex body organization.

Kingdom Plantae consists of multicellular, eukaryotic, photosynthetic organisms that possess cell walls made of cellulose.

Aplanospores are non-motile spores that lack flagella, whereas zoospores are motile spores that possess flagella.

Fungi thrive in warm and humid environments, which is why they are often found on bread or rotting fruit in such conditions.

Chitin is a polysaccharide that forms the structural component of fungal cell walls. It provides rigidity and protection. Desmids have cellulose cell walls, euglenoids (note: typo in option) have proteinaceous strips, and dinoflagellates have cellulose plates. Chitin is also found in arthropod exoskeletons.

Entamoeba is a genus of amoeboid protozoa. It is a parasite that lives in the intestines of humans and other animals.

Protozoa are considered to be primitive relatives of animals because they are heterotrophic and move to capture food, similar to animals.

Protozoa are heterotrophs that live as predators or parasites. They are classified based on their mode of locomotion.

Under suitable conditions, slime molds aggregate to form a structure called plasmodium, which can grow to several feet in length.

Slime molds are saprophytic protists. They feed on decaying twigs and leaves by engulfing organic material.

Euglenoids are mixotrophic; they are photosynthetic in the presence of sunlight but behave as heterotrophs in the absence of light.

Euglenoids are mostly fresh water organisms found in stagnant water. They possess a flexible body due to the pellicle.

Instead of a cell wall, euglenoids have a protein-rich layer called a pellicle, which makes their body flexible.

Dinoflagellates are mostly marine, photosynthetic, and possess two flagella, making all the provided statements correct.

The cell walls of diatoms are embedded with silica, making them indestructible and forming 'diatomaceous earth' after they die.
