Front

What organelle helps with cell digestion?

Back

Lysosomes are organelles that contain digestive enzymes to break down waste materials and cellular debris.

Front

What describes the arrangement of the cell membrane as bendable and made of many parts?

Back

The Fluid Mosaic Model describes the cell membrane structure, emphasizing its flexible nature and the presence of various proteins and lipids.

Front

What is the difference between rough and smooth ER?

Back

Rough ER has ribosomes on its surface, which are involved in protein synthesis, while smooth ER lacks ribosomes and is involved in lipid synthesis and detoxification.

Front

What structure do plant cells have for cell-to-cell communication?

Back

Plasmodesmata are channels that allow for communication and transport of materials between plant cells.

Front

How is food moved into the cell?

Back

Food is moved into the cell by endocytosis, a process where the cell membrane engulfs material to bring it inside.

Front

What is the function of ribosomes?

Back

Ribosomes are the sites of protein synthesis, translating messenger RNA (mRNA) into polypeptide chains.

Front

What is the role of the Golgi complex?

Back

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

Front

What is osmosis?

Back

Osmosis is the movement of water molecules across a selectively permeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Front

What are gap junctions?

Back

Gap junctions are specialized intercellular connections that allow for direct communication between adjacent cells.

Front

What is the primary function of the cell membrane?

Back

The cell membrane regulates what enters and exits the cell, providing protection and maintaining homeostasis.
