An organism is unicellular, reproduces asexually, and lives in a hot hydrothermal vent at the bottom of the ocean. This organism most likely belongs to the kingdom —
A. Eubacteria.
B. Animalia.
C. Archaea.
D. Protista.
What characteristic distinguishes members of the kingdom Plantae from members of the kingdom Fungi?
All plants are organisms composed of many cells, whereas all fungi are organisms composed of only one cell.
Plants are prokaryotic; fungi are eukaryotic.
Plants are producers; fungi are decomposers.
All plants are organisms that reproduce sexually, whereas all fungi are organisms that reproduce asexually.
Some members of the kingdom Protista are said to be plantlike. What characteristic distinguishes members of the kingdom Protista from members of the kingdom Plantae?
Protists mostly live in wet, moist environments, whereas plants can live in a large range of terrestrial habitats.
All protists are autotrophic, and all plants are heterotrophic.
Protists are made of cells that are considered prokaryotic, whereas plants are made of cells that are considered eukaryotic.
Protists are multicellular, and plants are unicellular.
Green algae, ferns, and pine trees are classified in the plant kingdom. These organisms share certain characteristics. Which of the following is a characteristic used to classify these organisms as plants?
They have an immune system.
They can be found in many different regions on Earth.
They engage in photosynthesis.
They produce flowers.
Some kingdoms contain organisms that can cause infection. Diseases that cause strep throat and malaria are from organisms in the –
A. kingdoms Archaea and Animalia.
B. kingdoms Protists and Fungi.
C. kingdoms Bacteria and Protists.
D. kingdoms Bacteria and Fungi.
Lithops optica is a species of succulent that belongs to the kingdom Plantae and
looks like a rock. What is a characteristic of Lithops optica that allows it to be
placed in this kingdom?
Lithops optica produces energy through photosynthesis.
Lithops optica is composed of cells that do not contain membrane-bound organelles.
Lithops optica is found mainly in dry environments.
Lithops optica must ingest other organisms to survive.
