Leaves




Leaves





The leaves provide photosynthesis, they are used as a defense mechanism for the plant, they also provide shading. You can recognize if a plant is a dicot or a monocot by the type of leaves. Dicot leaves have veins in a net pattern, while monocots veins are parallel. In this case the plant is a Dicot.
Leaves are like a greenhouse. The leaf inside is 90-95% humidity. Looking at a section of a leaf, the upper part is the Cuticle, which is a waxy layer. It’s the first line of protection to prevent water loss. The next layer is the Upper epidermis, a clear transparent layer, like the top of the greenhouse. The is the Palisade cell, which are tightly compact to prevent water loss, they also do photosynthesis. The part that does photosynthesis are the Spongy cells. The stomata allows for carbon dioxide to go in and oxygen and water vapors to go out. This process is called Evapotranspiration. The guard Cell close up if there is less then 90% humidity in the leaf.













Greenhouse Effect, Wisley




Greenhouse Effect, Wisley





RHS Wisley are repeating their butterfly exhibit, with hundreds of tropical butterflies let loose in the greenhouses. I was went over on Friday en route down to Dorset to have a look at them, and got thrown out at closing time when the sun was going down behind the palms and streaming windows.

There's a good number of shots from the afternoon and I'd recommend a visit to anyone - though you might want to warm your camera up before heading in. Coming in from the cold with a magnesium body, my kit instantly condensed a litre or so of ambient moisture and I spent the first fifteen minutes constantly drying it with a lens cloth.

Here's the first upload - more to come of the sunset that followed and the butterflies that preceded this one. Hope everyone is having a great weekend and enjoying life!
