Scientists debate how many kingdoms there are, but manyagree there are five. Here is how the five kingdoms are organized. Or, seehow some other scientists categorize life into sixkingdoms. Monera are single-celled organisms that don? Bacteria make up the entire kingdom. There are more forms of bacteria than any other organism on Earth. Some bacteria are beneficial to us, such as the ones found in yogurt. Others can cause us to get sick. Protists are mostly single-celled organisms that have a nucleus.
They usually live in water. Some protists move around, while others stay in one place. Examples of protists include some algae, paramecium, and amoeba. They decompose organic matter and acquire nutrients through absorption. While some fungal species contain toxins that are deadly to animals and humans, others have beneficial uses, such as for the production of penicillin and related antibiotics. Plants are extremely important to all life on earth as they provide oxygen, shelter, clothing, food, and medicine for other living organisms.
This diverse group contains vascular and nonvascular plants , flowering and nonflowering plants, as well as seed-bearing and non-seed bearing plants. As is true of most photosynthetic organisms, plants are primary producers and support life for most food chains in the planet's major biomes. This kingdom includes animal organisms. These multicellular eukaryotes depend on plants and other organisms for nutrition. Most animals live in aquatic environments and range in size from tiny tardigrades to the extremely large blue whale.
Most animals reproduce by sexual reproduction, which involves fertilization the union of male and female gametes. Actively scan device characteristics for identification. Use precise geolocation data. Select personalised content. Create a personalised content profile. Measure ad performance.

All of these pines are native to the state of California, USA. Monterey Pine P. Bishop Pine P. Santa Cruz Island Pine P. Whitebark Pine P. Limber Pine P. Beach Pine P. Lodgepole Pine P. Western White Pine P. Knobcone Pine P. Bristlecone Pine P. Foxtail Pine P.
Four-Leaf Pinyon P. Two-Leaf Pinyon P. One-Leaf Pinyon P. Ponderosa Pine P. Coulter Pine P. Digger Pine P. Torrey Pine P. Jeffrey Pine P. Sugar Pine P. Another species left image called the Washoe Pine P. In addition, the Beach and Lodgepole Pines are now recognized as subspecies of P. According to R. Lanner Conifers of California , , there may be other significant changes in the pines of California. Allozyme studies in two-leaf pinyons Pinus edulis of the New York Mountains indicate that these populations are biochemically and genetically consistent with nearby one-leaf pinyon Pinus monophylla , and that P.
The unusual New York Mountains population appears to be a 2-needle variant of P. According to Lanner, the latter species has five needles per fascicle and occurs in San Diego County.
The hybrid hypothesis might explain the perplexing variation in needle number for P. Foxtail pines Pinus balfouriana on the 11, ft m slopes of Alta Peak. The 13, ft. Left: Seed cones of cypress Cupressus from groves in southern California. Tecate cypress C.
