Consider the diagram of a eukaryote and a prokaryote. According to cell theory, answer choices. both are examples of primitive cells that are not capable of reproduction. both are examples of cells with a nucleus to direct the functions of life. both are single cells that carry out the functions of life.

The structures that make up a Eukaryotic cell are determined by the specific functions carried out by the cell. Thus, there is no typical Eukaryotic cell. Nevertheless, Eukaryotic cells generally have three main components: A cell membrane, a nucleus, and a variety of other organelles. THE CELL MEMBRANE 1. A cell cannot survive if it is totally ...

Consider the diagram of a eukaryote and a prokaryote. according to cell theory,

During the 1950s, scientists postulated the concept of prokaryotic cell and eukaryotic cell, with earlier groundwork being laid by Edouard Chatton, a French Biologist in 1925. Anatomically, cells vary with respect to their classification, therefore, prokaryotic cells and eukaryotic cells differ from each other quite drastically. The endosymbiotic theory is the accepted mechanism for how eukaryotic cells evolved from prokaryotic cells. It involves a cooperative relationship between two cells which allow both to survive—and eventually led to the development of all life on Earth. A prokaryote is a unicellular organism that lacks a nuclear membrane-enclosed nucleus. The word prokaryote comes from the Greek πρό (pro, 'before') and κάρυον (karyon, 'nut' or 'kernel'). In the two-empire system arising from the work of Édouard Chatton, prokaryotes were classified within the empire Prokaryota. But in the three-domain system, based upon molecular analysis ...

Add answer + 5 pts. report flag outlined. bell outlined. Eukaryotic cells have a nucleus enclosed within the nuclear membrane and form large and complex organisms. Protozoa, fungi, plants, and animals all have eukaryotic cells. They are classified under the kingdom Eukaryota. They can maintain different environments in a single cell that allows them to carry out various metabolic reactions. Endosymbiosis. The origin of eukaryotic cells was largely a mystery until a revolutionary hypothesis was comprehensively examined in the 1960s by Lynn Margulis. The endosymbiotic theory states that eukaryotes are a product of one prokaryotic cell engulfing another, one living within another, and evolving together over time until the separate ... Answer: The genetical composition (circular doble helix structure DNA and the genes themselves) and the types of rybosomes are similar between mitochondria and heterotrophic prokaryotes and between the chloroplasts and autotrophic prokaryotes. This similarities are actually the basis of the endo...

In prokaryote cell organization there is a nucleoid containing genomic DNA but it is not surrounded by membranes such as what defines the eukaryote nucleus (Martin & Koonin 2006). Eukaryotes such ... Endosymbiotic theory, which is often referred to as "symbiogenesis," is an evolutionary theory that attempts to explain the origin of eukaryotic cells. It is a hypothesis which essentially postulates that prokaryotes were what gave rise to the first eukaryotic cells and, if true, would rank amongst the most important evolutionary events in our history. Eukaryotic … A prokaryotic cell is a simple, single-celled (unicellular) organism that lacks a nucleus, or any other membrane-bound organelle. We will shortly come to see that this is significantly different in eukaryotes. Prokaryotic DNA is found in the central part of the cell: a darkened region called the nucleoid (Figure 1). Describe the origin of eukaryotic cells according to the endosymbiotic theory. (4 marks) ... Outline the cell theory (3 marks) ... 2. cells are the basic unit of life 3. cells come from pre-existing cells. Draw a labelled diagram of the ultrastructure of Escherichia coli as an example of a prokaryote. (4 marks) a. cell wall

3. The nucleus. The nucleus is a defining feature of eukaryotes [].Theories for the evolution of the nucleus are usually based (i) on invaginations of the plasma membrane in a prokaryote or (ii) on endosymbiosis of an archaeon in a eubacterial host or (iii) on an autogenous origin of a new membrane system including the nuclear envelope in a host of archaeal origin after acquisition of ... Thus, the origin of the eukaryotic cell is considered one of the most critical evolutionary events in the history of life on Earth. Had it not occurred sometime between 1.6 and 2 billion years ago, our planet would be a far different place, populated entirely by prokaryotes, single-celled organisms such as bacteria and archaea. Eukaryotic cells, which basically include every cell type except bacteria, are characterized by internal organelles surrounded by a membrane, which helps to increase their organization and efficiency. In contrast to prokaryotes, in eukaryotes the chromosomes are made of distinct lengths of DNA and are stored within a nuclear membrane. Consider the diagram of a eukaryote and a prokaryote. According to cell theory, Answer Choices A) both are single cells that carry out the functions of life. B) both are examples of primitive cells that are not capable of reproduction. C) both are examples of cells with a nucleus to direct the functions of life.

Eukaryotic cells are typically much larger than those of prokaryotes, having a volume of around 10,000 times greater than the prokaryotic cell. They have a variety of internal membrane-bound structures, called organelles, and a cytoskeleton composed of microtubules, microfilaments, and intermediate filaments, which play an important role in defining the cell's organization and shape.

Eukaryotic cells contain a nucleus (nuclear membrane). Eukaryotic cells include: plants, animals, fungi and protists ( a very heterogeneous group that are neither animals, plants or fungi and are often single cell and small e.g., protozoa).

Prokaryotes were around for a long, long time before eukaryotic cells appeared around 1.8 billion years ago. This has led us to think that the ancestor of all eukaryotic cells was a prokaryote. But to get from a prokaryote to a eukaryote, the cell needed to become a lot more complicated.
