In this lesson on photosynthesis, we discussed the various factors that influence the process in plants. Key elements include the amount and intensity of light, carbon dioxide concentration, temperature, and water availability. Light plays a crucial role in plant growth; insufficient light can hinder development, leading to phenomena like phototropism, where plants grow towards light. Additionally, we touched on geotropism, where plant growth is influenced by gravity, demonstrating how both light and gravity affect plant direction and health.
