What is programmed cell death?

Back

Apoptosis is the process of programmed cell death that occurs in multicellular organisms.

Front

What type of cell division does the diagram represent? (Mitosis or Meiosis)

Back

Mitosis is a type of cell division that results in two daughter cells, each having the same number of chromosomes as the parent nucleus.

Front

What type of cell division does the diagram represent? (Mitosis or Meiosis)

Back

Meiosis is a type of cell division that reduces the chromosome number by half, resulting in four daughter cells, each genetically distinct.

Front

What do autotrophs (producers) have that allows them to perform photosynthesis?

Back

Chloroplasts are the organelles in plant cells that conduct photosynthesis.

Front

Where do we get the energy to produce ATP from ADP and a phosphate group?

Back

Energy from food is used to convert ADP and a phosphate group into ATP.

Front

What is the primary function of mitochondria?

Back

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

Front

Define photosynthesis.

Back

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods with the help of chlorophyll.

Front

What is the role of ribosomes in a cell?

Back

Ribosomes are the cellular structures responsible for protein synthesis.

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 membrane-bound organelles.

Front

What is the function of the cell membrane?

Back

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