Biology CB5 Flashcard Cytoplasm & Cytoskeleton (M)

Front

What is the function of the cytoskeleton?

Back

The cytoskeleton helps to maintain cell shape and plays important roles in intracellular movement of substances and cell division.

Front

What forms the basis of the 'skeleton' inside the cell?

Back

Microtubules form the basis of the 'skeleton' inside the cell.

Front

What is the cytoplasm?

Back

The cytoplasm consists of everything inside the cell membrane of a eukaryotic cell, excluding the nucleus.

Front

What are microfilaments?

Back

Microfilaments are made of two thin actin chains twisted around one another, found in almost every cell, especially numerous in muscle cells.

Front

What are the functions of cytoplasm?

Back

The cytoplasm suspends cell organelles and provides a site for many biochemical reactions of the cell.

Front

What are microtubules?

Back

Microtubules are hollow tubes made of tubulin that provide structural support and shape to the cell.

Front

What role do intermediate filaments play in the cell?

Back

Intermediate filaments provide mechanical support and help maintain the shape of the cell.

Front

How does the cytoskeleton contribute to cell movement?

Back

The cytoskeleton facilitates cell movement by reorganizing its structure, allowing cells to change shape and move.

Front

What is the relationship between the cytoplasm and organelles?

Back

The cytoplasm suspends organelles, allowing them to function and interact within the cell.

Front

What is the significance of actin in microfilaments?

Back

Actin is a protein that forms microfilaments, crucial for muscle contraction and cell motility.
