Green plants are green because they contain a pigment called chlorophyll. Chlorophyll absorbs certain wavelengths of light within the visible light spectrum. Green light is not absorbed but reflected, making the plant appear green. Chlorophyll is found in the chloroplasts of plants.

Sure, plants are green because their cells contain chloroplasts which have the pigment chlorophyll which absorbs deep-blue and red light, so that the rest of the sunlight spectrum is being reflected, causing the plant to look green.

The leaves of most plants are green, because the leaves are full of chemicals that are green. The most important of these chemicals is called “chlorophyll” and it allows plants to make food so they can grow using water, air and light from the sun. So the green chemical chlorophyll is really important.

Chlorophyll is a green pigment that gives most plants their color. The reason that it is green is because it absorbs other colors of light such as red and blue, so in a way the green light is reflected out since the pigment does not absorb it.

Chlorophyll a absorbs light in the blue-violet region, chlorophyll b absorbs red-blue light, and both a and b reflect green light (which is why chlorophyll appears green).

The most common pigments in flowers come in the form of anthocyanins. These pigments range in color from white to red to blue to yellow to purple and even black and brown. A different kind of pigment class is made up of the carotenoids. Carotenoids are responsible for some yellows, oranges, and reds.

Maidenhair Fern (Adiantum) Maidenhair ferns are elegant plants that elevate any room, but are also very easy to kill! That being said, the beautiful leaves and overall look of this plant are more than worth the extra work. Many fern varieties, like the Boston fern and bird’s nest fern, thrive well in indirect sunlight.

Instructions:

1. Fill each cup with water half way.
2. Add 3 drops of food coloring into each of the cups.
3. Carefully cut the end of each of the flower’s stem.
4. Place each stem in a different colored water cup.
5. Wait one hour and observe your flowers’ petals.
6. Wait one day and observe your flowers’ petals.

Food dye can change the color of flowers when you put it in the plant’s water. Plants lose moisture through the tiny pores in their leaves. The longer the plants remain in the water, the darker the flowers become. If using cut flowers, the dye may even eventually flow back into the water, giving it additional tint.

Unlike the water, however, food coloring cannot evaporate. This means the food coloring can enter the plant but cannot leave it. Because the food coloring is non-toxic, this does not kill the plant, but it definitely does color the plant.

Liquid gel food coloring is a little more concentrated, and will make the final product more vibrant. If you’re coloring water for a drink, don’t add too much food coloring. Some food dyes, especially red colors, can have a bad flavor if you use too much of them.

Food coloring is non-toxic, so it doesn’t poison the plants. If you use enough of it, you may get a little tinting of the leaves of the plant after a while, but the plant still grows pretty much the same. p.s. Food colorings are often added to water for plants to alter the appearance of the plants.

Chlorophylls are natural green pigments ubiquitously present in plant kingdom, which play an important role in photosynthetic process, a vital function for life on Earth. The pigment chlorophyll is an important constituent of human diet as it is consumed as a part of vegetables and fruits.

Leaf blade

The green, flat and broad portion of the leaf is called lamina or leaf blade. The tip of the leaf blade is called leaf apex.

Most leaves have two main parts: (1) the blade and (2) the petiole, or leafstalk. The leaves of some kinds of plants also have a third part, called the stipules. The Blade, or lamina, is the broad, flat part of the leaf. Photosynthesis occurs in the blade, which has many green food-making cells.

Linear leaves have a long, narrow leaf shape, with sides that are almost parallel with each other and usually are more than four times longer than broad. Linear leaves can be flat, triangular, or square in cross section. They may also exhibit a distinct twist along their vertical axes.

Lobed leaves have distinct rounded or pointed projections, while unlobed leaves do not. Some lobed leaves are pinnate, meaning the lobes are located along a central axis, while others are palmate, meaning they radiate from a single point.

The most obvious aspect to examine is the shape of the leaf. If it is an uninterrupted shape, it is simple. If the shape divides into smaller leaf sets the leaf is compound. Identifying plant leaves that are compound divides them into subsets….Basic Leaf Types in Plants

1. Base.
2. Margins.
3. Tip.
4. Veins.
5. Petiole, if present.
6. Midrib.

Look at the base of the leaf, and if there is a bud there, it is a simple leaf. If you find the bud at the base of a grouping of leaves, they are compound leaves. Next, look at how leaves are positioned in relation to each other. If leaves occur in pairs directly opposite each other, they are called opposite leaves.

Leafsnap is a new free app that identifies trees. Go for a walk, take a shot of a leaf and this little wonder will identify its tree and give all kinds of information about it. The app is a result of a collaboration between Columbia University, the University of Maryland and the Smithsonian Institution.

Elm trees have oval-shaped leaves with saw-toothed edges and are pointy at the end. The veins of the leaf are usually very visible too. The bark is rough with deep grooves. The structure of an elm tree is like an umbrella with wide spreading limbs and some drooping branches.

If a tree has very rough bark, take a look at its ridges and furrows. These are actually gaps in the bark’s outer layers, called the rhytidome. Some species, like a white ash, can have ridges and furrows that intersect. Others, like the Northern red oak above, have uninterrupted ridges.

A tree’s bark is like our skin. If it comes off, it exposes the inner layer of live tissue to disease and insect infestation. It does not grow back. A tree will heal around the edges of the wound to prevent further injury or disease, but it will not grow back over a large area.

The outer bark is the tree’s protection from the outside world. Continually renewed from within, it helps keep out moisture in the rain, and prevents the tree from losing moisture when the air is dry. It insulates against cold and heat and wards off insect enemies.
