Front

What are pigments and where are they found?

Back

Pigments are molecules found in the thylakoid membranes of chloroplasts that absorb specific wavelengths of light energy.

Front

What process do most autotrophs use to make organic compounds like sugars?

Back

Most autotrophs make organic compounds, such as sugars, by a process called photosynthesis.

Front

What happens to chlorophyll molecules in trees before winter?

Back

As trees prepare to lose their leaves before winter, the chlorophyll molecules break down, revealing the colors of other pigments.

Front

What type of processes require oxygen?

Back

Aerobic processes require oxygen.

Front

What are chloroplasts and what is their function?

Back

Chloroplasts are large organelles in photosynthetic organisms that capture light energy.

Front

What is the role of thylakoid membranes in photosynthesis?

Back

Thylakoid membranes house the pigments that absorb light energy, which is essential for the photosynthesis process.

Front

Define photosynthesis in terms of its reactants and products.

Back

Photosynthesis is the process by which autotrophs convert carbon dioxide and water into glucose and oxygen using light energy.

Front

What is the significance of aerobic processes in cellular respiration?

Back

Aerobic processes are significant in cellular respiration as they produce more ATP compared to anaerobic processes, utilizing oxygen to fully oxidize glucose.

Front

How do pigments affect the color of leaves in autumn?

Back

In autumn, as chlorophyll breaks down, other pigments such as carotenoids and anthocyanins become visible, changing the color of leaves.

Front

What is the difference between autotrophs and heterotrophs?

Back

Autotrophs are organisms that produce their own food through photosynthesis or chemosynthesis, while heterotrophs obtain food by consuming other organisms.
