With more than 250,000 species, flowering plants make up about 90 percent of all plants, according to the Life Sciences department at Palomar College. Although we often think of flowers in terms of their aesthetic beauty, flowering plants in general have a much greater impact on the world. I...
Plants are classified into two main groups. This is a very basic way of classifying them. I. Non Vascular Plants Non vascular plants are known or thought to be the earliest living plants on the planet. They lack vascular tissues and wood that can give them structural support. They also lac...
Fossil fuels are finite resources; most estimates suggest that the proven reserves of oil are large enough to meet global demand at least until the middle of the 21st century. Fossil fuel combustion has a number of negative environmental consequences. Fossil-fueled power plants emit air pollutants...
Vegetable garden designs feature specific layouts that create an efficient system for plants and vegetables to grow by supporting each other and dealing with pests. With vegetable gardens, you can increase the growth of plants to enjoy healthy and homemade vegetables. These gardens also require ...
that worms eat help in expediting the decomposition process during digestion. Because of their feeding activity, they are perpetually on the move. This constant movement helps in the aerating and mixing of the soil, which in turn improves water uptake and stimulates the rapid growth of plants. ...
This type of camouflage is mainly seen in insects like spiders, leaf butterfly, dragonfly katydid, stick bugs or stick insect, etc. Mimicry Most of the animals copycat or mimic other animals to fool and escape from their predators. The mimicry can either be in appearance or behaviour or so...
Cohesion is seen in a droplet of water, when water is "pulled" by other water molecules up the stem of a plant by sticking to one another and when water has a high surface tension. All of these are due to the bonds between the molecules of water. What is cohesion in simple terms?
However, they lack true roots, stems, and leaves characteristic of vascular plants. Some of them are unicellular whereas others are multicellular. They may also form colonies. Most algae are aquatic. Others are terrestrial and may be found on moist soil, trees, and rocks. Some algal species ...

We can define the epidermis as one or more layers of cells forming the tough and protective outer layer of theskinorintegument(natural coating). The epidermis is a protective outer covering of many plants and animals. It may be comprised of a single layer, as in plants, or of several ...
