Describe the proposed relationship between prokaryotes and the organelles in eukaryotes?
The endosymbiotic theory proposes that organelles such as mitochondria and chloroplasts in eukaryotic cells were once independent prokaryotic organisms that were engulfed by a host cell. Over time, these organelles formed a symbiotic relationship with the host cell, eventually becoming integrated as essential components of eukaryotic cells. This theory is supported by evidence such as the presence of DNA and ribosomes in these organelles, similar to prokaryotic cells.
What is the term that is used to describe organisms that do not have an organism?
The term used to describe organisms that do not have a nucleus is "prokaryotes." Prokaryotes include bacteria and archaea, which are characterized by their simpler cellular structure compared to eukaryotes, which do have a nucleus. Prokaryotic cells lack membrane-bound organelles and typically have a single circular chromosome.
How would you describe the relationship between the original prokaryotic?
The original prokaryotic cells are believed to have arisen around 3.5 billion years ago and are the ancestors of all modern life. They exhibit a simple structure, lacking a nucleus and membrane-bound organelles, which distinguishes them from eukaryotic cells. The relationship between prokaryotes and eukaryotes is fundamental to understanding evolution, as eukaryotes are thought to have evolved from a symbiotic relationship between different prokaryotic species. This endosymbiotic theory suggests that certain organelles in eukaryotic cells, like mitochondria and chloroplasts, originated from absorbed prokaryotic cells.
What are the three names of cell oragelles and describe their function?
Mitochondria: Produce energy for the cell through cellular respiration. Nucleus: Contains the cell's genetic material (DNA) and controls cellular activities. Chloroplasts: Found in plant cells and are responsible for photosynthesis, converting sunlight into chemical energy.

Describe how eukaryotes evolved?
Although there is no fossil evidence for the evolution of eukaryotes from prokaryotes, scientists have inferred this through studying modern organisms. Scientists believe that eukaryotes evolved from prokaryotes because both have RNA and DNA as genetic material, contain ribosomes, and also utilize the identical 20 amino acids.
Which of these words describe humans eukaryote prokaryote protist fungus?
Humans are eukaryotes, meaning they have cells with a true nucleus and other membrane-bound organelles. Prokaryotes are simpler cells without a true nucleus, such as bacteria. Protists are a diverse group of eukaryotic organisms that are not plants, animals, or fungi. Fungi are also eukaryotes but are distinct from plants and animals, including mushrooms, yeasts, and molds.
Does eukaryote describe humans?
Indeed, humans Homo sapiens are eukaryotes. They are animalians from the Domain Eukarya. Being eukaryotes means their cells have their genetic material contained within a nucleus. There are many membrane-bound organelles to compartmentalise cellular activities and increase the efficiency of cell work.
Describe the basis for R H whittaker's five kingdom system?
R.H. Whittaker's five kingdom system was based on differences in cell structure, mode of nutrition, and reproduction in organisms. The five kingdoms were Monera (prokaryotes), Protista (unicellular eukaryotes), Fungi (non-photosynthetic eukaryotes), Plantae (photosynthetic eukaryotes), and Animalia (multicellular eukaryotes). This system aimed to reflect the diversity of life forms and their evolutionary relationships more accurately than previous classification systems.

Does both mendelian and non-mendelian law applicable to prokaryotes?
Yes, both Mendelian and non-Mendelian laws are applicable to prokaryotes. Mendelian laws, such as the law of segregation and the law of independent assortment, describe the inheritance patterns of genes in prokaryotes similarly to how they do in eukaryotes. Non-Mendelian laws, such as incomplete dominance or co-dominance, can also be observed in prokaryotes. However, it is important to note that prokaryotes have different mechanisms of gene transfer, such as horizontal gene transfer, which can give rise to non-Mendelian inheritance patterns.
What term is used to describe prokaryotes that can only get energy without oxygen?
Anaerobes
