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.

What is the most basic difference between autotrophs and heterotrophs?
Heterotrophs remain in one place, while autotrophs move around.
Heterotrophs get nutrition by eating, while autotrophs make their own food.
Heterotrophs respond to their surroundings, while autotrophs do not.
Heterotrophs excrete waste products, while autotrophs do not.
How do scientists classify the millions of organisms on Earth?
By placing them into a hierarchical system based on shared traits and characteristics
By placing them into an alphabetical system based on the discovering scientist
By placing them into a system based on population size and location
By placing them into a chronological system based on date of discovery
