Intracellular structures are objects found inside a cell. (Intra- means inside.)
They include subcellular organelles, or simply organelles. These are relatively complex components of the cell, such as the nucleus and the mitochondria.
Other intracellular structures include lumps of waste substances, particularly in plant cells.

What is meant when catalase is described as an 'intracellular enzyme'?
An intracellular enzyme is an enzyme that functions inside the cells of an organism, specifically within cell structures like organelles. Catalase is an intracellular enzyme that is primarily found in the peroxisomes of cells, where it helps break down hydrogen peroxide into water and oxygen.
Which cellular structures are associated with movement?
Cilia, flagella, and the cytoskeleton are cellular structures associated with movement. Cilia and flagella are hair-like structures that aid in cell motility, while the cytoskeleton provides structural support and is involved in intracellular movement.
What structures are found in animal cells but not in plant cell?
Centrioles and lysosomes are structures found in animal cells but not in plant cells. Centrioles are involved in cell division, while lysosomes are responsible for intracellular digestion.
Motor proteins interact with what types of cellular structures?
Motor proteins interact with cellular structures such as microtubules and actin filaments. They utilize the energy generated by ATP hydrolysis to move along these structures and carry out various cellular processes, including intracellular transport and cell division.
What are long hallow protein structures that give support to a cell?
Microtubules are long, hollow protein structures that give support to a cell. They are also involved in various cellular processes such as cell division, intracellular transport, and maintaining cell shape.
What cytoskeletal element involves in moving intracellular structures?
The cytoskeletal elements involve in the moving intracellular structures are the microfilaments. They are small rod-like structures found in most eukaryotic cells.
What element in a cell is involved in moving intracellular structures?
Microtubules, which are composed of tubulin proteins, are responsible for moving intracellular structures like organelles through the cell. They act as tracks for motor proteins to transport cargo along the cell's cytoskeleton.
What cellular structures is involved in intracellular digestion Golgi apparatus ribosomes lysosomes?
The main cellular structures involved in intracellular digestion are lysosomes and the Golgi apparatus. Lysosomes contain digestive enzymes that break down complex molecules, while the Golgi apparatus modifies and packages these enzymes for transport to the lysosomes. Ribosomes are responsible for protein synthesis and do not directly participate in intracellular digestion.
Why don't all cells demonstrate the presence of all intracellular structures?
Not all cells demonstrate the presence of all intracellular structures because cells are specialized and have specific functions. Different cells require different intracellular structures to carry out their unique functions. For example, muscle cells have more mitochondria to generate energy for contraction, while red blood cells lack a nucleus to make more space for carrying oxygen.
What is meant when catalase is described as an 'intracellular enzyme'?
An intracellular enzyme is an enzyme that functions inside the cells of an organism, specifically within cell structures like organelles. Catalase is an intracellular enzyme that is primarily found in the peroxisomes of cells, where it helps break down hydrogen peroxide into water and oxygen.
Microtubules are the primary structures in what?
Microtubules are the primary structures in the cytoskeleton of eukaryotic cells. They provide shape and support to the cell, allow for intracellular transport, and are involved in processes such as cell division and cell motility.
Are eubacteria intracellular or extracellular?
intracellular
Which cellular structures are associated with movement?
Cilia, flagella, and the cytoskeleton are cellular structures associated with movement. Cilia and flagella are hair-like structures that aid in cell motility, while the cytoskeleton provides structural support and is involved in intracellular movement.
What structures are found in animal cells but not in plant cell?
Centrioles and lysosomes are structures found in animal cells but not in plant cells. Centrioles are involved in cell division, while lysosomes are responsible for intracellular digestion.
Threadlike structures that control a cells activities are?
Microfilaments, microtubules, and intermediate filaments are threadlike structures that help control a cell's activities. They provide structural support, assist in cell division, and help with intracellular transport and movement. These structures are essential for maintaining cell shape and organization.
Do mollusks undergo extracellular digestion or intracellular digestion?
Intracellular
What are thin hreadlike structures found within the cytoplasm of a cell?
Thin threadlike structures found within the cytoplasm of a cell are called microfilaments. These filaments play a key role in cell movement, shape maintenance, and intracellular transport.
