Cell Structure and Transport Flashcard

Front

What is the function of the central vacuole in plant cells?

Back

The central vacuole stores nutrients, waste products, and helps maintain turgor pressure in plant cells.

Front

What is the role of the nucleus in a cell?

Back

The nucleus directs all cell activities and contains the cell's DNA.

Front

What is the primary function of mitochondria?

Back

Mitochondria are responsible for energy production through cellular respiration.

Front

What distinguishes eukaryotic cells from prokaryotic cells?

Back

Eukaryotic cells have a nucleus and membrane-bound organelles, while prokaryotic cells do not.

Front

What is passive transport?

Back

Passive transport is the movement of substances across a cell membrane without the use of energy.

Front

Define osmosis.

Back

Osmosis is the diffusion of water across a selectively permeable membrane.

Front

What is exocytosis?

Back

Exocytosis is the process by which a cell expels materials in vesicles that fuse with the cell membrane.

Front

What is the function of lysosomes?

Back

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

Front

What is the role of ribosomes in a cell?

Back

Ribosomes are responsible for protein synthesis.

Front

What is the difference between eubacteria and archaebacteria?

Back

Eubacteria are true bacteria with peptidoglycan in their cell walls, while archaebacteria are ancient bacteria that often live in extreme environments.
