|---|---|
| Mitochondrion | The cell organelle that is surrounded by two membranes and that is the site of cellular respiration |

What contains materials in a eukaryotic cell?
the nucleus
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.
What is the small sac used for transport in eukaryotic cells?
A vesicle is a small, membrane-bound sac that transports substances in cells. The ER moves proteins and other substances within eukaryotic cells. Vesicles that contain newly made proteins move through the cytoplasm from the ER to an organelle called the Golgi apparatus.
What are the small structures within a eukaryotic cell?
In addition to the nucleus, eukaryotic cells may contain several other types of organelles, which may include mitochondria, chloroplasts, the endoplasmic reticulum, the Golgi apparatus, and lysosomes. Each of these organelles performs a specific function critical to the cell’s survival.
What is a small spherical sac that are surround by a membrane?
Vesicles are small spherical shaped sacs surrounded by a single membrane and are classified by their contents. Certain types of vesicles called transport vesicles are found only in eukaryotic cells.
What is peroxisome and its function?
Peroxisomes are organelles that sequester diverse oxidative reactions and play important roles in metabolism, reactive oxygen species detoxification, and signaling. Oxidative pathways housed in peroxisomes include fatty acid β-oxidation, which contributes to embryogenesis, seedling growth, and stomatal opening.
Do eukaryotes have a cell membrane?
Eukaryotes are organisms whose cells have a nucleus and other organelles enclosed by a plasma membrane.
What are structures in eukaryotic cells?
Eukaryotic Cell Structure a membrane-bound nucleus. numerous membrane-bound organelles (including the endoplasmic reticulum, Golgi apparatus, chloroplasts, and mitochondria) several rod-shaped chromosomes.
What is the eukaryotic cell membrane made of?
phospholipid bilayer
Eukaryotic Plasma Membrane: The eukaryotic plasma membrane is a phospholipid bilayer with proteins and cholesterol embedded in it. The cell membrane is an extremely pliable structure composed primarily of two adjacent sheets of phospholipids. Cholesterol, also present, contributes to the fluidity of the membrane.
What are the little sacs that carry molecules?
Vesicles Vesicles are small sacs. They carry different molecules to where they are needed.
What is eukaryotic cell structure?
Eukaryotic Cell Structure Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes. a membrane-bound nucleus. numerous membrane-bound organelles (including the endoplasmic reticulum, Golgi apparatus, chloroplasts, and mitochondria) several rod-shaped chromosomes.
What material surrounds a plant cell?
Cell Membrane: This is a protective layer that surrounds every cell and separates it from its external environment. It is found just inside the cell wall and is made up of complex lipids (fats) and proteins.
