Biology STAAR Prep Flashcard #8

Front

What are biomolecules that provide quickly available energy?

Back

Carbohydrates, particularly simple sugars like glucose, provide quickly available energy.

Front

How does cellular respiration differ from photosynthesis in terms of energy sources?

Back

Cellular respiration uses glucose as the main source of energy, while photosynthesis converts light energy into chemical energy.

Front

What phase of the cell cycle is represented by the increase in DNA content?

Back

The S phase (Synthesis phase) is when DNA is replicated.

Front

What is phototropism?

Back

Phototropism is the growth of a plant in response to light, where auxin causes elongation of cells on the shady side.

Front

What does xylem tissue transport in plants?

Back

Xylem tissue transports water and minerals absorbed by the roots.

Front

Define auxin in the context of plant hormones.

Back

Auxin is a plant hormone that regulates growth by promoting cell elongation, particularly on the side of the plant that is away from light.

Front

What is the main product of cellular respiration?

Back

The main products of cellular respiration are carbon dioxide, water, and ATP (energy).

Front

What role do plant hormones play in plant growth?

Back

Plant hormones act as chemical messengers that regulate various aspects of growth and development.

Front

What is the difference between geotropism and phototropism?

Back

Geotropism is the growth response of a plant to gravity, while phototropism is the growth response to light.

Front

What is the significance of the S phase in the cell cycle?

Back

The S phase is crucial for DNA replication, ensuring that each daughter cell receives an identical set of chromosomes.
