What is the role of wolves in an ecosystem?

Back

Wolves help maintain the balance of ecosystems by controlling prey populations, which can prevent overgrazing and promote biodiversity.

Front

What is cell differentiation?

Back

Cell differentiation is the process by which a less specialized cell becomes a more specialized cell type, leading to different shapes and functions.

Front

What is a vacuole?

Back

A vacuole is a membrane-bound organelle in cells that primarily functions in storage of substances such as nutrients, waste products, and water.

Front

Why is crop rotation important for soil health?

Back

Crop rotation helps preserve soil quality by preventing nutrient depletion, reducing soil erosion, and controlling pests and diseases.

Front

What do prokaryotic cells lack that eukaryotic cells have?

Back

Prokaryotic cells lack membrane-bound organelles and a nucleus, while eukaryotic cells have both.

Front

What is the primary function of cytoplasm in a cell?

Back

Cytoplasm is the gel-like substance within a cell that holds organelles in place and is the site for many metabolic processes.

Front

How do different cell types arise from the same DNA?

Back

Different cell types arise from the same DNA through the activation of specific genes during differentiation, leading to varied structures and functions.

Front

What is biodiversity and why is it important?

Back

Biodiversity refers to the variety of life in an ecosystem. It is important for ecosystem resilience, providing resources, and maintaining ecological balance.

Front

What is the significance of membrane-bound organelles in eukaryotic cells?

Back

Membrane-bound organelles allow for compartmentalization of cellular processes, increasing efficiency and specialization within the cell.

Front

What is the function of enzymes in biological systems?

Back

Enzymes act as catalysts that speed up chemical reactions in biological systems without being consumed in the process.
