Which term describes a thin membrane bound structure inside a eukaryotic cell?
peroxisome, membrane-bound organelle occurring in the cytoplasm of eukaryotic cells. Peroxisomes contain enzymes that oxidize certain molecules normally found in the cell, notably fatty acids and amino acids.
Which term describes a tiny membrane bound structure inside a eukaryotic cell organelle cytoplasm protein nucleic acid?
21. Which term describes a tiny, membrane-bound structure inside a eukaryotic cell? organelle.
Which molecule is bound in a membrane inside of a eukaryotic cell?
The Nucleus & Its Structures Eukaryotic cells have a true nucleus, which means the cell’s DNA is surrounded by a membrane. Therefore, the nucleus houses the cell’s DNA and directs the synthesis of proteins and ribosomes, the cellular organelles responsible for protein synthesis.
What is a membrane bound structure in eukaryotic cells that contains the DNA?
These membrane-bound structures are called organelles. In eukaryotes, the cell’s genetic material, or DNA, is contained within an organelle called the nucleus, where it is organized in long molecules called chromosomes.
Is peroxisome membrane-bound?
Peroxisomes are single-membrane–bounded organelles found in nearly all eukaryotic cells. Peroxisomes are thought to basically proliferate by division, although they do not contain DNA (1).
What is defined as an intracellular membrane-bound component of a eukaryotic cell?
Terms in this set (101) organelle. which defines an intracellular, membrane- bound component of a eukaryotic cell. endosymbiosis. biologists believe that eukaryotic cells evolved from prokaryotes through which process. organ.
Why do eukaryotic cells have membrane-bound organelles?
Eukaryotic cells are generally much larger and more complex than prokaryotic. Because of their larger size, they require a variety of specialized internal membrane-bound organelles to carry out metabolism, provide energy, and transport chemicals throughout the cell.
What are some membrane-bound organelles?
Examples of membrane-bound organelles are nucleus, endoplasmic reticulum, Golgi apparatus, mitochondria, plastids, lysosomes and vacuoles.
What are membrane bound structures in a cell called?
Eukaryotic cells contain many membrane-bound organelles. An organelle is an organized and specialized structure within a living cell. The organelles include the nucleus, ribosomes, endoplasmic reticulum, Golgi apparatus, vacuoles, lysosomes, mitochondria, and, in plants, chloroplasts.
Are lysosomes membrane bound?
Lysosomes break down macromolecules into their constituent parts, which are then recycled. These membrane-bound organelles contain a variety of enzymes called hydrolases that can digest proteins, nucleic acids, lipids, and complex sugars. The lumen of a lysosome is more acidic than the cytoplasm.
What are the internal structures of a eukaryotic cell?
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.
Is nucleus membrane bound?
A nucleus is a membrane-bound organelle that contains the cell’s chromosomes. Pores in the nuclear membrane allow for the passage of molecules in and out of the nucleus.
