Study Notes

Plant Growth Responses

Elongation and bending towards light is caused by phototropism, a growth process influenced by light.
Auxins, a type of plant hormone, redistribute unevenly in response to light, promoting cell elongation on the shaded side.

Hydrotropism

Hydrotropism refers to plants' growth towards moisture, aiding in root development.
This ensures that plants can access water resources, promoting survival in varying environmental conditions.

Receptors in Organisms

Multicellular organisms possess two primary types of receptors:
- Mechanoreceptors: Detect mechanical changes (like pressure and touch).
- Chemoreceptors: Respond to chemical stimuli, including taste and smell.

Factors Affecting Light Availability

Changes in light availability for plants can be caused by:
- Seasonal variations, leading to shorter or longer daylight hours.
- Environmental obstructions such as clouds, haze, and seasonal foliage.
- Urbanization and deforestation, which can alter light exposure in ecosystems.

Importance of Water for Plants

Water is essential for photosynthesis, the process by which plants convert light energy into chemical energy.
It aids in nutrient transport within the plant and is crucial for maintaining turgor pressure, supporting plant structure.
