3.4: Unique Characteristics of Eukaryotic Cells Eukaryotic cells have evolved an endomembrane system, containing membrane-bound organelles involved in transport. These include vesicles, the endoplasmic reticulum, and the Golgi apparatus. The smooth endoplasmic reticulum plays a role in lipid biosynthesis, carbohydrate metabolism, and detoxification of toxic compounds.

Structural Biochemistry/Cell Organelles/Mitochondria The purpose of the mitochondria in the eukaryote is to provide cellular respiration to the cell. The endosymbiotic theory asserts that the mitochondria came to be part of the eukaryote over time through a symbiotic relationship. The mitochondria consists of two membranes, the inner membrane and the outer membrane.

- Archaea or archaebacteria evolved separately from eubacteria and eukaryotes. They are similar with eubacteria in being prokaryotes and lacking distinct cell nucleus.They differ in terms of ribosomal structure, the possession of introns (in some species) and in membrane structure or composition.rchaea or archaebacteria evolved separately from eubacteria and eukaryotes. They are similar with eubacteria in being prokaryotes and lacking distinct cell nucleus.

In what ways are prokaryotes and eukaryotes different - AP BIO? In addition to the plasma membrane, eukaryotic cells contain internal membrane-bound structures called organelles. Organelles, such as mitochondria and chloroplasts, are both believed to have evolved from prokaryotes that began living symbiotically within eukaryotic cells.These vital organelles are involved in metabolism and energy conversion within the cell.nd even with the evolution of more complex eukaryotic cells, prokaryotes are supremely successful. All bacteria and bacteria-like Archaea are prokaryotic organisms. Eukaryotic Cells Eukaryotic cells are more complex, evolving from a prokaryote-like predecessor.

What is the endosymbiotic theory of the origin of eukaryotic cells? Report Abuse. The endosymbiotic hypothesis explains the origins of eukaryotic organelles like the mitochondrion and chloroplast. There is much evidence that suggests that those organelles descended from prokaryotic cells that were engulfed by a eukaryote as an endosymbiont.est Answer: The endosymbiotic theory concerns the origins of mitochondria and plastids (e.g. chloroplasts), which are organelles of eukaryotic cells.

The  Endosymbiotic Origin of Domain Eukaryota The mitochondrion is different from most other organelles because it has its own circular DNA (similar to the DNA of prokaryotes) and reproduces independently of the cell in which it is found, one of the major pieces of evidence supporting endosymbiosis.

Endosymbiont The endosymbiosis theory explains the origins of organelles such as mitochondria and chloroplasts in eukaryotic cells. The theory proposes that chloroplasts and mitochondria evolved from certain types of bacteria that eukaryotic cells engulfed through endophagocytosis.any instances of endosymbiosis are obligate; that is, either the endosymbiont or the host cannot survive without the other, such as the gutless marine worms of the genus Riftia, which get nutrition from their endosymbiotic bacteria.

Eukaryote The defining feature that sets eukaryotic cells apart from prokaryotic cells (Bacteria and Archaea) is that they have membrane-bound organelles, especially the nucleus, which contains the genetic material, and is enclosed by the nuclear envelope.ukaryote cells include a variety of membrane-bound structures, collectively referred to as the endomembrane system. Simple compartments, called vesicles or vacuoles, can form by budding off other membranes.

- The endosymbiotic theory concerns the origins of mitochondria and chloroplasts, which are organelles of eukaryotic cells. According to this theory, these originated as prokaryotic endosymbionts, which came to live inside eukaryotic cells.he theory postulates that the mitochondria evolved from aerobic bacteria (probably proteobacteria, related to the rickettsias), and that the chloroplast evolved from endosymbiotic cyanobacteria (autotrophic prokaryotes).

- Endosymbiosis. The similar DNA structure in mitochondria and chloroplasts is explained by the theory of endosymbiosis, which was originally proposed by Lynn Margulis in her 1970 work The Origin of Eukaryotic Cells.. According to Margulis's theory, the eukaryotic cell came from the joining of symbiotic prokaryotes.itochondria and chloroplasts are organelles found in eukaryotic organisms (e.g. organisms with a nucleus).

Endomembrane system The endomembrane system is composed of the different membranes that are suspended in the cytoplasm within a eukaryotic cell. These membranes divide the cell into functional and structural compartments, or organelles. In eukaryotes the organelles of the endomembrane system include: the nuclear membrane, the endoplasmic reticulum, the Golgi apparatus, lysosomes, vesicles, endosomes and the cell membrane, among others. The system is defined more accurately as the set of membranes that form a single

Cytoskeletal architecture and its evolutionary significance in amoeboid eukaryotes and their mode of locomotion Based on this result, it can be hypothesized the last common ancestor of Amoebozoa had a complex network of fibril MTs limited within the cell subcortex, thus conferring the unique adaptive features of amoeboid locomotion.

Structural Biochemistry/Three Domains of Life/Archaea Several other characteristics also set the archaea apart. Both bacteria and eukaryotes have membranes composed mainly of glycerol-ester lipids, whereas archaea have membranes composed of glycerol-ether lipids. These differences may be an adaptation on the part of archaea to hyperthermophily.

Domain Eukaryota Eukaryota is one of the three domains of life contianing organisms whose cells contain complex structures enclosed within complex membranes call endomembranes. These organisms are called Eukaryotes and are either singular-or multiple-celled. The defining membrane-bound structure that differentiates eukaryotic cells from prokaryotic cells is the cell nucleus, within which the genetic material and many other cell bodies are contained.

What Characteristics Do All Eukaryotic Cells Have in Common? In comparison to prokaryotic cells, eukaryotic cells are at least 10 times larger. Their cytoplasm is composed of both ribosomes and cystol. Protected by their plasma membrane, they also have protections for each organelle in the form of individual membranes. The plasma membrane is the site for signaling and transport functions for the entire cell. Within eukaryotic cells, the endomembrane system is a network of membranes sharing materials.

Module 2 Part A Cell Structure The endomembrane system has four components. 1. The nuclear membrane. 2. The endoplasmic reticulum (ER). 3. The Golgi apparatus. 4. Membranous sacs called vesicles. This system compartmentalizes the cell and carries molecules from one part of the system to another part. 1. Endoplasmic Reticulum. The ER is a complicated system of membranous channels and flattened vesicles (saccules) . It is responsible for making lipids and proteins and it sometimes stores small ions. 2. Golgi Apparatus. The Golgi apparatus consists of numerous flattened saccules.

- Eukaryotes possess complex intracellular organelles, such as mitochondria and chloroplasts (such as the spiral chloroplast in the alga Spirogyra). How did these structures evolve? Endosymbiosis refers to a condition in which one cell lives inside another cell for the benefit of both.

Evolution of prokaryotic and eukaryotic cells Living things have evolved into three large clusters of closely related organisms, called domains: Archaea, Bacteria, and Eukaryota. Archaea and Bacteria are small, relatively simple cells surrounded by a membrane and a cell wall, with a circular strand of DNA containing their genes.They are called prokaryotes.hese tiny organelles in the cell not only produce chemical energy, but also hold the key to understanding the evolution of the eukaryotic cell. The complex eukaryotic cell ushered in a whole new era for life on Earth, because these cells evolved into multicellular organisms.

- Eukaryotic cells contain a nucleus and membrane-bound organelles. All multicellular organisms consist of eukaryotic cells. Eukaryotic cells are thought to have evolved from primitive single-celled prokaryotic cells. All cells are surrounded by a cell membrane (plasma membrane). The cell membrane is semipermeable, allowing some substances to pass into the cell and blocking others. It is composed of a double layer of phospholipids and embedded proteins. Plant cells have an additional layer surrounding them called the cell wall. The cell wall is made of nonliving material called cellulose. The centrosome (also called the microtubule organizing center) is a small body located near the nucleus. The centrosome is where microtubules are made.
