Pili are hair-like structures that allow the transfer of DNA between bacteria and enable bacteria to adhere to each other and other surfaces.
In Plantae, vacuoles are large for structural support and nutrient storage; in Animalia, they are small for waste removal.
The cytoplasm contains dissolved substances and enzymes in water; it is the main site of cell metabolism.
A thicker layer of peptidoglycan causes the cell to take up the crystal violet stain used in the Gram stain test, making it Gram-positive.
It contains multiple linear chromosomes with DNA associated with histone proteins and has a double membrane with pores that allow mRNA to enter the cytoplasm.
80S ribosomes are relatively larger ribosomes used for protein synthesis, found in eukaryotic cells.
The nucleoid is a region in prokaryotic cells that resembles a nucleus, where the cell's circular DNA is located.
Examples of membrane-bound organelles in eukaryotic cells include mitochondria, endoplasmic reticulum, Golgi apparatus, and lysosomes.
Prokaryotic cells contain 70S ribosomes, which are involved in protein synthesis.
The cell wall is composed of peptidoglycan, providing strength and support, and preventing the cell from bursting.
The cytoskeleton in eukaryotic cells is composed of microtubules and microfilaments.
Naked DNA in prokaryotic cells refers to the circular DNA molecule that is not associated with proteins, located in the nucleoid region.
Eukaryotic cells contain 80S ribosomes.
A membrane structure with a network of tubules and ribosomes attached to its surface, serving as the site of protein synthesis and responsible for transporting proteins to the Golgi Apparatus.
The nucleus stores chromosomes, each consisting of one long DNA molecule associated with histones (proteins).
The cell wall in prokaryotic cells is composed of peptidoglycan.
The nucleus of eukaryotic cells contains chromosomes made of DNA bound to histones, enclosed in a double membrane with pores.
A membrane structure with a network of tubules that lacks ribosomes, involved in lipid synthesis and detoxification.
Mitochondria are double-membrane-bound organelles that provide energy through aerobic respiration.
The flagellum is a tail responsible for locomotion in prokaryotic cells.
70S ribosomes are the type of ribosomes found in prokaryotic cells, responsible for protein synthesis and are relatively smaller than eukaryotic ribosomes.
Ribosomes found in eukaryotic cells that are involved in protein synthesis.
The cytoplasm in prokaryotic cells is the gel-like substance within the cell membrane where cellular processes occur, but it is not divided into compartments by membranes.
A series of stacked, flattened membranes that modify and package proteins to be exported from the cell.
The prokaryote cell wall is a rigid structure that provides support and protection, commonly found in Gram-positive eubacteria such as Bacillus and Staphylococcus.
Prokaryotic cell structure varies among different species, such as the absence of cell walls in phytoplasmas and mycoplasmas, but these details are not required for basic understanding.
It is responsible for aerobic respiration, producing ATP in eukaryotic cells.
A network of protein microtubules that maintains cell shape, moves organelles, and is involved in nuclear division (mitosis/meiosis) in eukaryotic cells.
The plasma membrane in prokaryotic cells regulates the movement of substances in and out of the cell, maintaining homeostasis.
A structure that allows bacteria to adhere to each other and surfaces, and facilitates the exchange of genetic material between bacteria.
Specialized vesicles in eukaryotic cells that contain digestive enzymes.
The plasma membrane controls the entry and exit of substances, maintains internal chemistry, and is composed of phospholipids.
A region in prokaryotic cells that contains a single circular chromosome with naked DNA, meaning no proteins are associated with it.
