What is phototropism?

Back

Phototropism is the growth of a plant in response to light direction, causing it to bend toward the light source.

Front

What is thigmotropism?

Back

Thigmotropism is the growth response of a plant to touch or physical contact, such as the closing of mimosa leaves when touched.

Front

What is geotropism?

Back

Geotropism is the growth response of a plant to gravity, where roots grow downward and stems grow upward.

Front

What role do chloroplasts play in plant cells?

Back

Chloroplasts are organelles that conduct photosynthesis, converting light energy into chemical energy in the form of glucose.

Front

What is the function of mitochondria in plant cells?

Back

Mitochondria are the organelles that produce energy (ATP) through cellular respiration in plant cells.

Front

What is phloem?

Back

Phloem is the plant tissue responsible for transporting food (glucose) from the leaves to other parts of the plant.

Front

What is xylem?

Back

Xylem is the plant tissue that transports water and minerals from the roots to the leaves.

Front

How do plants detect light?

Back

Plants detect light through specialized cells in the shoot tips that respond to light direction.

Front

What is the significance of Charles Darwin's experiments on plants?

Back

Darwin's experiments demonstrated how plants respond to light, leading to the understanding of phototropism.

Front

What is the difference between phototropism and geotropism?

Back

Phototropism is the response to light, while geotropism is the response to gravity.
