Inside a leaf of a tree, there are many tiny parts that work together to keep the plant alive. The outer layer, called the epidermis, protects the leaf. Small openings called stomata allow air to move in and out, letting the leaf take in carbon dioxide and release oxygen. Inside, there are green cells with chloroplasts that contain chlorophyll, which captures sunlight to make food through photosynthesis. The leaf also has veins made of xylem and phloem that carry water, minerals, and food to and from the rest of the plant. All these parts together help the leaf act like a food factory for the tree. #tree #leaf #oxygen #photosynthesis #scrolllink #nature #life #mystry

Sunlight is very important for life on Earth. It provides heat and light, keeping our planet warm and bright. Plants use sunlight to make food and release oxygen through photosynthesis, which supports all living things. The Sun’s energy also drives the water cycle by causing evaporation and rainfall. It creates seasons and day–night cycles, which shape climates and natural habitats. For humans, sunlight helps produce vitamin D and regulates sleep patterns. Without sunlight, Earth would be cold, dark, and lifeless.’ -Life Unfold #sunlight #earth #plants #humans #energy #scrolllink
