What is active transport?

Back

Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration, requiring energy (ATP).

Front

Does active transport require energy?

Back

Yes, active transport requires energy to move substances against their concentration gradient.

Front

What process is shown in a cell cycle diagram?

Back

The cell cycle is the series of events that take place in a cell leading to its division and replication.

Front

What is the function of the nucleus in a cell?

Back

The nucleus contains most of the cell's genetic information and controls cellular activities.

Front

What is DNA?

Back

DNA (deoxyribonucleic acid) is the molecule that carries the genetic instructions for life and is responsible for the development and functioning of living organisms.

Front

What is the role of DNA in protein synthesis?

Back

DNA contains the instructions for making proteins, which are essential for the structure and function of cells.

Front

What are the main stages of the cell cycle?

Back

The main stages of the cell cycle are interphase (G1, S, G2) and mitotic phase (mitosis and cytokinesis).

Front

What is mitosis?

Back

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

Front

What is meiosis?

Back

Meiosis is a type of cell division that reduces the chromosome number by half, resulting in four genetically diverse gametes.

Front

What is a cladogram?

Back

A cladogram is a diagram that shows the evolutionary relationships among various biological species based on shared characteristics.
