Cell Cycle and other Graphs Z

Front

What is the cell cycle?

Back

The cell cycle is the series of phases that a cell goes through to grow and divide, including interphase, mitosis, and cytokinesis.

Front

What happens during interphase?

Back

Interphase is the longest phase of the cell cycle where the cell grows, duplicates its DNA, and prepares for mitosis.

Front

What is mitosis?

Back

Mitosis is the process of cell division where one cell divides to produce two identical daughter cells.

Front

What is cytokinesis?

Back

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

Front

Why do cells divide when they reach a certain size?

Back

Cells divide to maintain an efficient surface area-to-volume ratio; as cells grow, their volume increases faster than their surface area.

Front

What is a keystone species?

Back

A keystone species is a species that has a disproportionately large effect on its environment relative to its abundance.

Front

How do sea otters affect sea urchin populations?

Back

Sea otters control sea urchin populations by preying on them, which helps maintain the balance of the ecosystem.

Front

What is the relationship between sea urchin size and shell thickness?

Back

Generally, larger sea urchins tend to have thicker shells, which provides them with better protection against predators.

Front

What is a surface area-to-volume ratio?

Back

The surface area-to-volume ratio is a measure that describes how much surface area a cell has relative to its volume, affecting nutrient uptake and waste removal.

Front

What is the significance of the surface area-to-volume ratio in cells?

Back

A higher surface area-to-volume ratio allows for more efficient exchange of materials, which is crucial for cell function.
