Level 7 Chapter 1

Front

What is the primary mode of locomotion for Euglena?

Back

Euglena uses flagella to move through water.

Front

What role does chlorophyll play in photosynthesis?

Back

Chlorophyll captures sunlight, which is essential for photosynthesis in plants.

Front

How do bacteria contribute to nutrient recycling in ecosystems?

Back

Bacteria recycle nutrients by decomposing dead tissue and using it as food.

Front

What organisms are responsible for red tides?

Back

Dinoflagellates cause red tides when they produce an algal bloom.

Front

What is the function of pigments in cyanobacteria?

Back

The pigments in cyanobacteria are used to capture sunlight for photosynthesis.

Front

What is the significance of flagella in protists?

Back

Flagella are important for the movement and locomotion of many protists, including Euglena.

Front

What is the process by which plants convert sunlight into energy?

Back

Photosynthesis is the process by which plants convert sunlight into chemical energy.

Front

What are the environmental impacts of algal blooms?

Back

Algal blooms can deplete oxygen in water, leading to dead zones and harming aquatic life.

Front

What is the difference between autotrophic and heterotrophic organisms?

Back

Autotrophic organisms produce their own food (e.g., plants), while heterotrophic organisms obtain food by consuming other organisms.

Front

What is the role of cyanobacteria in aquatic ecosystems?

Back

Cyanobacteria are primary producers that contribute to oxygen production and serve as a food source in aquatic ecosystems.
