How does an artist use line?
Line can also create the illusion of form in a drawing. By varying the line quality an artist can show form in a drawing with just the use of line. Line can also indicate shadow and form through the use of cross contour lines. Cross contour lines follow the contours of the object.
What does lines do in art?
It is one-dimensional and can vary in width, direction, and length. Lines often define the edges of a form. Lines can be horizontal, vertical, or diagonal, straight or curved, thick or thin. They lead your eye around the composition and can communicate information through their character and direction.
How are lines made in art?
In the visual arts, lines are made when you draw or paint marks on a paper, canvas, or when materials such as wood, glass and metal are bent or shaped. Lines can be horizontal, vertical or diagonal, straight, curved or free-form. They can be thick or thin, light or dark.
Why are lines important in drawing?
One of the most fundamental elements of art is the line. An important feature of a line is that it indicates the edge of a two-dimensional (flat) shape or a three-dimensional form. A shape can be indicated by means of an outline and a three-dimensional form can be indicated by contour lines.
What are the essential elements for life?
From the mightiest blue whale to the most miniscule paramecium, life as we know it takes dramatically different forms. Nonetheless, all organisms are built from the same six essential elemental ingredients: carbon, hydrogen, nitrogen, oxygen, phosphorus and sulfur (CHNOPS).
What are the 7 micronutrients?
There are 7 essential plant nutrient elements defined as micronutrients [boron (B), zinc (Zn), manganese (Mn), iron (Fe), copper (Cu), molybdenum (Mo), chlorine (Cl)]. They constitute in total less than 1% of the dry weight of most plants.
What are the function of essential elements?
PRIMARY (MACRO) NUTRIENTS Nitrogen (N), Phosphorus (P), and Potassium (K) are the most frequently required in a crop fertilization program. Nitrogen is necessary for the formation of amino acids, proteins, DNA and RNA. It is essential for plant cell division and vital for plant growth.
What is the difference between essential and beneficial elements?
The beneficial elements are not deemed essential for all crops but may be vital for particular plant taxa. The distinction between beneficial and essential is often difficult in the case of some trace elements. These elements are not critical for all plants but may improve plant growth and yield.
What are the criteria of essentiality?
Three Criteria for Essentiality of Nutrients: A plant cannot complete its life-cycle in the absence of the element. The action of the element must be specific, with no other element being able to completely substitute for it. The element must be shown to be directly involved in the nutrition of the plant.
