Princ Bio Ch. 3 Organelle Flashcard

Front

What are cilia and flagella?

Back

Cilia and flagella are part of the cytoskeleton that assist in attachment and movement. They appear as tiny hairs (cilia) or a long tail (flagella).

Front

What is cytoplasm?

Back

Cytoplasm is the jelly-like substance in which organelles are suspended inside the cell.

Front

What is the function of the endoplasmic reticulum?

Back

The endoplasmic reticulum acts like a 'conveyor belt', moving proteins out of the cell. It has two types: rough (with ribosomes) and smooth (without ribosomes).

Front

What role do centrioles play in the cell?

Back

Centrioles are part of the cytoskeleton and play a crucial role during cell division.

Front

What is the nucleus?

Back

The nucleus is the 'control center' of the cell, containing most of the cell's DNA.

Front

What is the function of ribosomes?

Back

Ribosomes are the sites of protein synthesis in the cell.

Front

What is the golgi apparatus?

Back

The golgi apparatus modifies, sorts, and packages proteins and lipids for secretion or delivery to other organelles.

Front

What is the role of mitochondria?

Back

Mitochondria are known as the 'powerhouses' of the cell, generating ATP through cellular respiration.

Front

What is the function of lysosomes?

Back

Lysosomes contain enzymes that break down waste materials and cellular debris.

Front

What is the cytoskeleton?

Back

The cytoskeleton is a network of fibers that provides structural support, helps in cell movement, and organizes organelles.
