While hiking through the forest, a student finds an unusual plant-like organism. The student takes a sample of the organism. When he observes the sample later under the microscope, he sees cells with a nucleus and cell wall, but no chloroplasts. Without chloroplasts, he knows the organism cannot be autotrophic. The organism is most likely a member of what kingdom?
A
animalia
B
plantae
C
fungi
D
archaebacteria
Explanation: 

Detailed explanation-1: -If a specimen shows the presence of a living cell under the microscope, then it is considered a living organism.

Detailed explanation-2: -Answer and Explanation: If you observed a species’ cells under a microscope and saw both cell walls and mitochondria, you could conclude that it was a eukaryote from either the Kingdom Plantae, Fungi, or Protista (specifically an alga). The species cannot be a prokaryote because prokaryotes do not have mitochondria.

Detailed explanation-3: -In order for something to be classified as living, it must grow and develop, use energy, reproduce, be made of cells, respond to its environment, and adapt. While many things meet one or more of these criteria, a living thing must meet all of the criteria.

Detailed explanation-4: -Final answer: Cell wall distinguishes a plant cell from an animal cell.
