What cell organelles lack membranes as part of their structure?
Ribosomes and centrioles are cell organelles that lack membranes as part of their structure. Ribosomes are responsible for protein synthesis, while centrioles play a role in cell division.
The hollow tubes of protein that help maintain the shape of the cell is what?
The hollow tubes of protein that help maintain the shape of the cell are called microtubules. They are part of the cytoskeleton and play crucial roles in cell structure, cell division, and intracellular transport.
Part of the cell which play a rule during cell division?
it is part of the animal cell which play a rule during cell division?
What role does ribosome play in a animal cell?
It helps make protein
Are hollow tubes of protein that maintain cell shape and permit movement of cell organelles. A) Muscles B) Ribosomes C) Microtubules D) Nuclear pores?
C) Microtubules are hollow tubes of protein that maintain cell shape and facilitate the movement of cell organelles. They are part of the cytoskeleton and play a crucial role in cellular structure, transport, and division.
What cell parts are made of protein fibers?
Cell parts made of protein fibers include the cytoskeleton, which consists of microfilaments, intermediate filaments, and microtubules. These protein fibers provide structural support, aid in cell shape maintenance, and facilitate cell movement. Additionally, they play crucial roles in intracellular transport and cell division.
Structural features that contain the protein actin and help to control the shapes of cells are?
Structural features that contain the protein actin and help to control the shapes of cells are actin filaments, also known as microfilaments. These filaments are part of the cytoskeleton and play a key role in cell shape maintenance, cell movement, and cell division. They can assemble and disassemble rapidly to alter cell shape as needed.
Are cell phones part of mass media?
Yes, cell phones are a big part in the play of mass media.
What is extra nuclear part?
The extra-nuclear part of a cell refers to any structure or component of the cell that is located outside of the nucleus. This can include organelles like mitochondria, endoplasmic reticulum, and Golgi apparatus, as well as the cytoplasm and cell membrane. These structures play vital roles in cellular functions such as energy production, protein synthesis, and transportation of molecules within the cell.
How does protein synthesis play a role in the cell cycle?
Protein synthesis is essential for the cell cycle because it produces the proteins needed for cell growth, division, and repair. During different phases of the cell cycle, specific proteins are synthesized to regulate processes such as DNA replication, cell division, and cell signaling. This ensures that the cell cycle progresses smoothly and accurately.
What specialized protein exists in the neural cell membrane?
Ion channels are specialized proteins that exist in the neural cell membrane. They play a crucial role in allowing ions to pass through the cell membrane, which is essential for generating electrical signals in neurons.
The substance being synthesized in the cell is most likely a?
protein, as proteins are the most abundant macromolecules synthesized in cells and play a variety of essential roles in cell structure and function. Proteins are synthesized through a process called protein synthesis, which involves transcription of DNA to mRNA and translation of mRNA to protein at ribosomes.
