What is the function of the endoplasmic reticulum in a cell?

Back

The endoplasmic reticulum (ER) is involved in the synthesis of proteins and lipids, and it plays a role in the transport of materials within the cell.

Front

What is the role of chloroplasts in plant cells?

Back

Chloroplasts are organelles that use energy from sunlight to convert carbon dioxide and water into glucose through the process of photosynthesis.

Front

What is cytoplasm and what is its significance in a cell?

Back

Cytoplasm is a jellylike substance that fills the interior of a cell, providing a medium for chemical reactions and housing organelles.

Front

What are ribosomes and what do they do?

Back

Ribosomes are molecular machines that synthesize proteins by translating messenger RNA (mRNA) into polypeptide chains.

Front

What is the function of the golgi apparatus?

Back

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

Front

What are the two types of endoplasmic reticulum and their functions?

Back

The two types of endoplasmic reticulum are rough ER, which has ribosomes and synthesizes proteins, and smooth ER, which synthesizes lipids and detoxifies certain chemicals.

Front

How do chloroplasts and mitochondria differ in their functions?

Back

Chloroplasts convert light energy into chemical energy through photosynthesis, while mitochondria generate ATP through cellular respiration.

Front

What is the structure of a ribosome?

Back

Ribosomes are composed of ribosomal RNA (rRNA) and proteins, forming two subunits that come together during protein synthesis.

Front

What is the significance of the cytoskeleton in a cell?

Back

The cytoskeleton provides structural support, helps maintain cell shape, and facilitates cell movement and division.

Front

What is the role of lysosomes in a cell?

Back

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