What are the functions of an eukaryotic cell?
– Ribosomes. Ribosomes are complexes made of ribosomal RNA and protein. – Endoplasmic reticulum. The endoplasmic reticulum is consisting of a complicated system of membranous cannes and sacules. – The Golgi apparatus. The GA sorts the modified molecules and packges them into vesicles that depart from the outer face. – Lysosomes. – Peroxisomes. – Vacuoles. – Chloroplasts.
What is evidence that a cell is eukaryotic?
The answer seems to be symbiosis – in other words, teamwork. Evidence supports the idea that eukaryotic cells are actually the descendents of separate prokaryotic cells that joined together in a symbiotic union.
What do eukaryotic cells have the ability to do?
Eukaryotic cells have the ability to absorb other cells by phagocytosis. Characterized by the presence of the nucleus, formed by a rope DNA (the free ends) surrounded by two layers reticulum (nuclear envelope). Eukaryotic DNA forms a complex with a large number of proteins. 4.0.
What is an excellent example of eukaryotic cell?
Eukaryotic cells are defined as cells containing organized nucleus and organelles which are enveloped by membrane-bound organelles. Examples of eukaryotic cells are plants, animals, protists, fungi. Their genetic material is organized in chromosomes.
What is the difference between prokaryotic and eukaryotic replication?
The main difference between prokaryotic and eukaryotic DNA replication is that prokaryotic DNA replication occurs through a single origin of replication whereas eukaryotic DNA replication occurs through multiple replication origins.
What are examples of eukaryotic microorganisms?
The structures located in eukaryotic cells may include the endoplasmic reticulum, golgi apparatus, mitochondria, and ribosomes , as well as chloroplasts in photosynthetic cells. Examples of eukaryotic microorganisms include fungi, algae, protozoa and various microscopic parasitic worms.
What do eukaryotes usually contain?
an organism of the Eucaryotae, whose cells (eukaryotic cells) have a true nucleus that is bounded by a nuclear membrane, contains the chromosomes, and divides by mitosis. Eukaryotic cells also contain membrane-bound organelles, such as mitochondria, chloroplasts, lysosomes, and the Golgi apparatus.
What are the 13 organelles?
The following points highlight the thirteen important Organelles of Cytoplasm. Some of the organelles are: 1. Endoplasmic Reticulum 2. Ribosomes 3. Golgi Apparatus 4. Lysosomes 5.
Is Golgi apparatus prokaryotic or eukaryotic?
The Golgi apparatus occurs in all eukaryotic cells except male gametes of bryophytes and pteridophytes, mature sieve tubes, some fungal cells, and mature sperms and RBCs of animals. It is also absent in prokaryotic cells.
Which cells have DNA?
These cells have DNA that can be extracted. Cells called neutrophils, eosinophils, basophils and monocytes circulate in the body through the bloodstream. T cells and B cells, or lymphocytes , are also in blood. Saliva is another bodily fluid that contains DNA.
