Question

General effects of cadmium on plants

Answers

GPT 3.5
1. Inhibition of photosynthesis: Cadmium interferes with the functioning of chloroplasts in plants, leading to a decrease in photosynthetic activity. This can result in reduced plant growth and productivity.

2. Oxidative stress: Cadmium induces the production of reactive oxygen species (ROS) in plants, causing oxidative damage to cellular components such as proteins, lipids, and DNA. This can lead to cellular dysfunction and cell death.

3. Disruption of nutrient uptake: Cadmium can compete with essential nutrients such as zinc, iron, and calcium for uptake by plant roots. This can result in nutrient deficiencies and impaired plant growth.

4. Alteration of root morphology: Cadmium exposure can lead to changes in root structure, such as inhibited root elongation, reduced root biomass, and altered root architecture. This can affect the plant's ability to access water and nutrients from the soil.

5. Hormonal imbalance: Cadmium can disrupt the balance of plant hormones, such as auxins, cytokinins, and gibberellins, which play a crucial role in regulating growth and development processes in plants. This can lead to stunted growth, abnormal flowering, and reduced seed production.

6. Impaired water relations: Cadmium can reduce the water uptake and transpiration rates in plants, leading to water stress symptoms such as wilting, leaf necrosis, and reduced turgor pressure.

7. Interference with enzyme activity: Cadmium can inhibit the activity of key enzymes involved in various metabolic pathways in plants, such as photosynthesis, respiration, and antioxidant defense. This can disrupt normal cellular functions and impair plant growth and development.
