Question
Plants and animals are ________.
- Unicellular
- Multicellular
- More cellular
- Photo cellular
Hint:
All species of animals, land plants and most fungi are multicellular, as are many algae, whereas a few organisms are partially uni- and partially multicellular, like slime molds and social amoebae such as the genus Dictyostelium.
The correct answer is: Multicellular
Kingdom Monera [10,000 species]: Unicellular and colonial--including the true bacteria (eubacteria) and cyanobacteria (blue-green algae).
Eukaryotic Cells With Nuclei And Membrane-Bound Organelles:
2. Kingdom Protista (Protoctista) [250,000 species]: Unicellular protozoans and unicellular & multicellular (macroscopic) algae with 9 + 2 cilia and flagella (called undulipodia).
3. Kingdom Fungi [100,000 species]: Haploid and dikaryotic (binucleate) cells, multicellular, generally heterotrophic, without cilia, and eukaryotic (9 + 2) flagella (undulipodia).
4. Kingdom Plantae [250,000 species]: Haplo-diploid life cycles, mostly autotrophic, retaining embryo within female sex organ on the parent plant.
5. Kingdom Animalia [1,000,000 species]: Multicellular animals, without cell walls and without photosynthetic.
