The Leaf It's amazing what's inside a leaf
Ponds are among the richest and the most interesting natural environments to observe. Tomake a pond it is sufficient to have a garden or, a meadow or a wood near your home. It isnot necessary to be large, a square meter (9 square feet) of surface is sufficient, buttwo(18 sq. ft.) are better. Find a shady position in the garden. Dig a hole of about 2square meters, 50 cm(2 feet) deep. At least one side, the border has to gently slope downto allow to little animals to enter and leave, for hedgehogs and opossums to drink and tobirds to bath without being too deep. Put some sand in the bottom. Leave the grass on theside. Bare roots are okay. Waterproof the hole with a tarpaulin of white PVC. Why white?Because you can see aquatic animals better when they come near the shore. Cover the borderof the tarpaulin with the grass sod. Allow the tarpaulin to extend for at least 40 cm (16inches) beyond the sloping shore. In this position you can keep the water in such a way tocreate the typical conditions of a marsh. Fill up the pond with tap water and shovel somesand or soil in the bottom: they will benefit the aquatic plants. Go to a natural pond ormarsh and collect some aquatic plants. If it is possible, carry some gallons of water fromthe pond and pour them into your puddle, which will be enriched with microorganisms,algae, and animals, which live in ponds. In few days, your little pond will become greenwith algae and very rich of protozoa. Rapidly dragonflies will come to lay eggs, boatflies, coleoptera and aquatic spiders also will come. In the spring, frogs and newtswill come to lay eggs. The observation of the life in a pond is fascinating. You canremain for hours watching the organisms, which live in this ecosystem. Buy books torecognize the organisms that live in the ponds. See bibliography (5, 6). These texts willalso give you also useful information on the habits of these plants and animals. For anexercise, note your observations in a book, glue pictures, and sketch drawings. Everyyear, during the fall, you should clear out the pond. Shovel out the stinking mud, washthe tarpaulin, or changed it if it leaks, put some tap water, winter rain will supply theremaining part. In spite of what shopkeepers will tell you, your pond does not need pumpsto circulate water, nor aerators, nor falls, nor fountains, nor anything else. The pond isbetter to be as natural as possible. Little ponds of private gardens are very important toamphibians. Avoid introducing fish. They will eat the eggs of the amphibians and thetadpoles. Moreover, the newts will keep the pond free from the mosquito larvae. When thereare tadpoles, your pond will be visited by water snakes, with difficulty you will noticeof them!... and --- don't be frightened: they are harmless!

We also have to be careful when studying green plants because in the light the green parts of these plants carry out photosynthesis as well as respiration.
This tutorial introduces photosynthesis
Equally or more important is that in order to carry out photosynthesis, the plant needs to get carbon dioxide into the leaf, and the source is the air outside of the leaf. Small openings in the leaf (each one a stoma; plural, stomata) allow outside gases into the interior of the leaf. A stoma, however, is a two-way door: water inside of the leaf is free to diffuse to the outside, a process known as . The stomata, like doors, can be opened and closed; but closing the stomata to conserve water means that the carbon dioxide necessary for photosynthesis cannot get in. Thus some plants can access carbon dioxide only during the cooler parts of the day, when transpiration is much slower than at hotter temperatures. When the stomata close, making carbon dioxide unavailable, photosynthesis ceases, yet another reason for slow growth.
They take in and release gasses used in photosynthesis and respiration
Roots - absorb water and essential minerals (such as nitrates) from the soil, all of which get distributed throughout the plant
Stem - transports essential materials around the plant - water is taken from the roots to the leaves for photosynthesis and glucose is taken from the leaves (product of photosynthesis) and taken to other parts of the plant for respiration
