What is the function of ribosomes in a cell?

Back

Ribosomes are responsible for protein synthesis, translating messenger RNA (mRNA) into polypeptide chains.

Front

What organelle is responsible for converting sunlight into chemical energy?

Back

Chloroplasts are the organelles that convert sunlight into chemical energy through the process of photosynthesis.

Front

What limits the size of a cell?

Back

The size of a cell is usually limited by the membrane's ability to transport nutrients in and waste out efficiently.

Front

Where are most proteins first synthesized in a cell?

Back

Most proteins are first synthesized on ribosomes, which can be found on the rough endoplasmic reticulum (Rough ER).

Front

What is the role of the Golgi body in a cell?

Back

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

Front

What is the structure of the rough endoplasmic reticulum (Rough ER)?

Back

The Rough ER is a network of membranes studded with ribosomes, giving it a 'rough' appearance.

Front

What is the primary function of the cell membrane?

Back

The cell membrane regulates the movement of substances in and out of the cell, maintaining homeostasis.

Front

What is the difference between prokaryotic and eukaryotic cells?

Back

Prokaryotic cells lack a nucleus and membrane-bound organelles, while eukaryotic cells have a nucleus and various organelles.

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 mitochondria in a cell?

Back

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