What is geotropism?
Click to flip
Geotropism is the growth of plant parts in response to the force of gravity.
Click to flip
Which part of the plant exhibits positive geotropism?
Click to flip
Roots exhibit positive geotropism as they grow towards the gravitational pull.
Click to flip
Which part of the plant exhibits negative geotropism?
Click to flip
The stem of a plant exhibits negative geotropism as it grows up, away from the gravitational pull.
Click to flip
What role does auxin play in geotropism?
Click to flip
Auxin is a plant hormone that regulates growth, and its differential distribution in the plant causes bending towards or away from gravity.
Click to flip
How does auxin distribution differ in shoots for geotropism?
Click to flip
In shoots, auxin accumulates on the lower side, causing cells to elongate more and the shoot to bend upwards.
Click to flip
How does auxin distribution differ in roots for geotropism?
Click to flip
In roots, auxin inhibits growth on the underside, causing the root to bend downwards.
Click to flip
What is another name for geotropism?
Click to flip
Geotropism is also known as gravitropism.
Click to flip
Explain how geotropism benefits plants.
Click to flip
Geotropism helps roots anchor the plant and find nutrients and water in the soil, and shoots can grow towards light for photosynthesis.
Click to flip
What is the role of statoliths in geotropism?
Click to flip
Statoliths are specialized organelles that help plants sense gravity and direct growth accordingly.
Click to flip
Can geotropism be observed in non-plant organisms?
Click to flip
Yes, geotropism can be observed in some fungi and other microorganisms.
Click to flip
How does geotropism interact with phototropism in plants?
Click to flip
Geotropism and phototropism often work together to enable plants to optimize growth and resource acquisition.
Click to flip
Can geotropism occur in artificial conditions like space?
Click to flip
In space, the lack of gravity affects geotropism, often leading researchers to study how plants grow in microgravity.
Click to flip
What is the primary environmental factor influencing geotropism?
Click to flip
The primary environmental factor influencing geotropism is gravity.
Click to flip
How do agricultural practices utilize geotropism?
Click to flip
Agricultural practices exploit geotropism to ensure crops grow properly for optimal yield by properly orienting planting.
Click to flip
Is geotropism a permanent or reversible plant response?
Click to flip
Geotropism is generally a reversible response, as plants can change their growth direction with changing gravitational cues.
