Answer 2

Answer:

Trees (most of them, depending on the type) are full of green leaves and blossoming in the summer, as temperatures are normally optimum for the tree at this moment. The trees are blossoming and flowering in the spring. This isn't all that different from summer. Trees begin to shed their foliage in autumn, and their leaves change the beautiful colours of maroon, crimson, and somewhat purple. This is due to the cooler temperatures and lower humidity than in the summer and spring. As the cold season approaches, trees lose the majority of their leaves. Some trees, particularly evergreens, nearly never shed the majority of their leaves in any season.

Explanation:

• When the temperature rises and the sun shines, humans and animals seek safety in the shade – or air conditioning! Plants, on the other hand, are not the same. Plants, like trees, do not leave their roots when living, thus they must be able to withstand temperature swings throughout the year.
• The process through which trees lose their leaves is similar to several functions that occur within your body! Plants, like humans, contain hormones. Chemical messengers are commonly referred to as phytohormones in plants. Phytohormones control a variety of metabolic activities in plants, including fruit development. Auxins are a kind of phytohormone that is required for optimal growth throughout the plant's life cycle. Auxins, which are particularly vital for growth, are partly responsible for trees loosing their leaves. Another phytohormone that contributes to seasonal variations is ethylene. Abscission is the scientific name for an organism's shedding.
• Environmental factors influence autin levels. Less auxin penetrates a plant's leaves when winter or the dry season approaches. As a result, fewer nutrients reach the leaves, causing them to die and fall off the tree. Plants monitor variations in light, temperature, precipitation, or a combination of these elements to determine when to cease feeding their leaves. The evolutionary benefit of abscission is that it permits a plant to effectively ration out the little nourishment available during the winter/dry season.
