Structure and Functions of Living Organisms

Front

What is differentiation?

Back

Differentiation is the process by which a less specialized cell becomes a more specialized cell type, allowing for the development of different cell types from the same fertilized egg.

What is the role of mitochondria in a cell?

Back

Mitochondria are known as the powerhouse of the cell; they are responsible for producing energy through respiration.

Front

What happens during DNA replication?

Back

During DNA replication, the DNA molecule unwinds and separates into two strands, allowing for the creation of two identical copies of the DNA.

Front

How does DNA code for proteins?

Back

DNA codes for proteins by arranging nitrogen bases (adenine, thymine, cytosine, guanine) in a specific sequence, which determines the amino acid sequence of the protein.

Front

What is the difference between muscle cells and blood cells?

Back

Muscle cells and blood cells differ because different genes are activated in each type of cell, leading to their unique structures and functions.

Front

What is the function of ribosomes in a cell?

Back

Ribosomes are the cellular structures responsible for synthesizing proteins by translating messenger RNA (mRNA) into amino acid sequences.

Front

What is the significance of the cell membrane?

Back

The cell membrane controls the movement of substances in and out of the cell, maintaining homeostasis and protecting the cell's internal environment.

Front

What is the process of photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to convert carbon dioxide and water into glucose and oxygen.

Front

What is mitosis?

Back

Mitosis is the process of cell division that results in two genetically identical daughter cells from a single parent cell.

Front

What are homologous chromosomes?

Back

Homologous chromosomes are pairs of chromosomes that have the same structure and gene sequence, one inherited from each parent.
