What evidence would you look for when identifying a eukaryotic cell?
The cells of eukaryotic organisms have several distinguishing characteristics. Above all, eukaryotic cells are defined by the presence of a nucleus surrounded by a complex nuclear membrane. Also, eukaryotic cells are characterized by the presence of membrane-bound organelles in the cytoplasm.
Which organelle provides evidence that this cell is a eukaryote?
The nucleus is particularly important among eukaryotic organelles because it is the location of a cell’s DNA. Two other critical organelles are mitochondria and chloroplasts, which play important roles in energy conversion and are thought to have their evolutionary origins as simple single-celled organisms.
Which of the following clues would tell you whether a cell is prokaryotic or eukaryotic?
The correct option is c. whether or not the cell is partitioned by internal membranes. Internal membranes are one of the characteristic features of eukaryotic cells that distinguish them from prokaryotic cells.
Which organelle provides evidence that eukaryotic cells originated when a large ancient eukaryotic cell engulfed small free living prokaryotes?
Scientists hypothesize that the first protists evolved from prokaryotes. Evidence indicates that eukaryotic organelles such as mitochondria and chloroplasts originated as prokaryotes that lived inside other, larger prokaryotic cells. This hypothesis is called the endosymbiotic hypothesis or the Theory of Endosymbiosis.
What is found in the eukaryotic cells?
Each eukaryotic cell has a plasma membrane, cytoplasm, a nucleus, ribosomes, mitochondria, peroxisomes, and in some, vacuoles; however, there are some striking differences between animal and plant cells.
Which statement is true about eukaryotic cells?
Eukaryotic cells are larger than prokaryotic cells and have a “true” nucleus, membrane-bound organelles, and rod-shaped chromosomes. The nucleus houses the cell’s DNA and directs the synthesis of proteins and ribosomes.
Which descriptions apply to eukaryotic cells?
Which descriptions apply to Eukaryotic cells? are usually multicellular, contain a true nucleus, contain membrane bound organelles. An interaction between two organisms in which one usually benefits is known as . Which term describes the relationship in which one organism lives inside the other one.
Which is the main arena for cellular activities?
cytoplasm
The main arena of various types of cellular activities is performed by the cytoplasm. Cytoplasm consists of a bulk of protoplasm excluding nucleus and vacuoles.
When observing a cell through the microscope what would confirm that the cell is eukaryotic and not prokaryotic?
Prokaryotic cells lack a nucleus and membrane-bound organelles and tend to be 0.5-5 um in size. Eukaryotic cells have a membrane-enclosed nucleus that serves to contain and separate the DNA and other nuclear components from the remainder of the cell.
What evidence suggests that chloroplasts and mitochondria may have originated when an early ancestor of a eukaryotic cell engulfed a prokaryotic cell?
When chloroplasts and mitochondria were floating around as prokaryotes, they were engulfed by another prokaryote, hence the double membrane. Another key evidence is the fact that chloroplasts and mitochondria replicate their own DNA, transcribe their own RNA and make their own proteins and enzymes!
