For comparison, Earth is about 4.5 billion years old, and multicellular organisms developed relatively recently compared to unicellular, microbial life [source: Nature]. Classifying Extremophiles These depictions of single-celled organisms fall in the Monera kingdom, home of prokaryotes. Harnett/...
Studies in yeast have provided some clues to how cell size might be determined in unicellular eukaryotes; yet little attention has been paid to this issue in multicellular organisms. Reproducible cell sizes might be achieved in the dividing cells of multicellular organisms by the coordination of grow...
What do all complex multicellular organisms have in common? Organisms: An organism is considered a living form, such as an animal, plant, fungi, or bacteria. As of this point, Earth is the only planet in the Solar System that contains a variety of organisms from tiny, unicellular organisms...
Human beings are multicellular organisms. Using examples from two different body systems, explain the different levels of cell organization within those systems. What are the unique characteristics of chemical substances and macromolecules utilized by living systems?
Multicellular organisms have a hierarchical structural organization, in which any one system is made up of numerous parts and is itself a component of the next level. HS-LS1-2.Develop and use a model to illustrate the hierarchical organization of interacting systems that provide specific functions ...
How do trees develop a healthy root system? What influences axillary bud growth? How do non-green plants carry out photosynthesis? How do spore-bearing plants survive? How does phytoplankton grow? Why did plants become multicellular? How does soil pollution affect plant growth?

and organs,2inflammation by efferocytosis,3and tissue regeneration.4,5,6Indeed, regulated cell death can only be an evolutionary selected process when it serves the selectable benefit of the whole organism in case of multicellular organisms. This implies a prerequisite that cell death should have ...
Five kingdom classification is done on the basis of5 factors- cell structure, body organization, mode of nutrition, mode of reproduction, and phylogenetic relationship. It also puts unicellular and multicellular organisms into different groups. ...
Why is density dependence important in multicellular organisms? What is biology? Why is biology important in the real world? Is the element phosphorus required by plants? Why or why not? Why is the ovule so important for the development of a plant?
