1. Three basic life processes carried out by plants include photosynthesis, respiration, and transpiration. Photosynthesis is the process by which plants convert sunlight, carbon dioxide, and water into glucose and oxygen, while respiration is the process of breaking down glucose to release energy. Transpiration is the loss of water vapor through the stomata of plant leaves, which is necessary for nutrient absorption and maintaining plant hydration.
2. Plant structures such as leaves, roots, and flowers play crucial roles in promoting the survival, defense, and reproduction of plants. Leaves are responsible for photosynthesis, roots anchor the plant and absorb nutrients from the soil, and flowers aid in reproduction by attracting pollinators and producing seeds.
3. Plants respond to external stimuli in various ways, such as through tropisms, which are directional growth responses to stimuli like light (phototropism), gravity (geotropism), and touch (thigmotropism). These responses relate to life processes as they allow plants to adapt to their environment and optimize their chances of survival and reproduction.
4. Other plant responses to external stimuli include nastic movements, which are non-directional movements triggered by various factors. For instance, the opening and closing of flowers, such as morning glory flowers, in response to light intensity are nastic movements. These responses are essential for successful pollination and seed dispersal, enabling plants to carry out their life processes effectively.
