Chapter 4 Test

Which best describes a main difference between organisms in kingdom Fungi and organisms in kingdom Plantae?

• Organisms in kingdom Plantae are always multicelled, while organisms in kingdom Fungi are always single-celled.

• Organisms in kingdom Plantae can be motile for most of their lives, while organisms in kingdom Fungi are non-motile.

• Organisms in kingdom Plantae are heterotrophs, while organisms in kingdom Fungi are autotrophs.

• Organisms in kingdom Plantae have chloroplasts in their cells, while organisms in kingdom Fungi do not.

The kingdom Fungi and the kingdom Bacteria are both useful to the recycling of inorganic nutrients because both contain

• parasitic organisms

• decomposers.

• digestive lysosomes

• mitochondria

A genus is a taxonomic grouping that identifies a collection of species. When a scientist discovers a new species, how is this species assigned to a genus?

• It is put with the species with which it shares the most physical characteristics

• It is put with the species that live in similar climate zones

• It is put into a new genus until more information can be gathered

• It is put with the species that live in the same geographical region

Which level of organization do the dragonflies and lily pads, Z, that are interacting in this environment represent?

• an organism

• a community

• a population

• an ecosystem

Which of the following refers to the place where a species lives?

• niche

• habitat

• ecosystem

• biome

Ecologists study the interaction of organisms at five different levels. Which best places the levels in order from smallest to largest?

• population→ ecosystem→ organism→community→ biome

• community→ organism→ population→ biome→ecosystem

• organism→ population→ community→ecosystem→ biome

• ecosystem→ organism→ community→ biome→population

Of the six kingdoms now recognized,

• four are plants, and two are animals

• four are bacteria, and two are eukarya

• two are prokaryotes, and four are eukaryotes

• two are eukaryotes, and four are prokaryotes

All organisms in the kingdom Plantae

• are multi-celled, photosynthetic, and contain membrane-bound organelles.

• reproduce sexually, contain membrane-bound organelles and photosynthetic

• are multi-celled, heterotrophic, and do not contain membrane-bound organelles

• reproduce asexually, do not contain membrane bound

  organelles and photosynthetic.

Daniel found an organism that is multicellular, heterotrophic and has a cell wall made of chitin. In what kingdom does this organism belong?

• Eubacteria

• Plantae

• Fungi

• Protista

Unlike organisms in the taxonomic group Animalia, organisms classified as Fungi often digest their food

• by engulfing the food source

• with the assistance of microbes

• internally by absorbing the nutrients through

  root-like structures

• externally by excreting digestive enzymes and

  then absorbing the nutrients
