Cell, Cell Cycle, and Cell Theory

Front

What is the function of mitochondria in a cell?

Back

Mitochondria are known as the 'powerhouse' of the cell because they produce energy in the form of ATP through cellular respiration.

Front

What are the two types of endoplasmic reticulum?

Back

The two types of endoplasmic reticulum are Rough Endoplasmic Reticulum (RER), which has ribosomes on its surface and is involved in protein synthesis, and Smooth Endoplasmic Reticulum (SER), which is involved in lipid synthesis and detoxification.

Front

What is the main purpose of the cell cycle?

Back

The cell cycle is the series of events that lead to cell division and replication, allowing for growth, repair, and reproduction of cells.

Front

What are the stages of mitosis?

Back

The stages of mitosis are Prophase, Metaphase, Anaphase, and Telophase.

Front

What happens during prophase?

Back

During prophase, the chromatin condenses into visible chromosomes, the nuclear envelope breaks down, and the mitotic spindle begins to form.

Front

What is cytokinesis?

Back

Cytokinesis is the final stage of cell division where the cytoplasm divides, resulting in two separate daughter cells.

Front

What is the role of the nucleus in a cell?

Back

The nucleus serves as the control center of the cell, housing the cell's DNA and coordinating activities such as growth, metabolism, and reproduction.

Front

What is the significance of the cell theory?

Back

The cell theory states that all living organisms are composed of cells, cells are the basic unit of life, and all cells arise from pre-existing cells.

Front

What occurs during anaphase?

Back

During anaphase, the sister chromatids are pulled apart to opposite poles of the cell, ensuring that each daughter cell will receive an identical set of chromosomes.

Front

What is the difference between plant and animal cell division?

Back

In plant cells, a cell plate forms during cytokinesis, while in animal cells, the cell membrane pinches inwards to separate the two daughter cells.
