Is the distribution of visual weight in a work of art?
Balance is the distribution of the visual weight of objects, colors, texture, and space. Such movement can be directed along lines, edges, shape, and color within the work of art. Pattern is the repeating of an object or symbol all over the work of art. Repetition works with pattern to make the work of art seem active.
What is visual balance in art?
Balance in Art refers to the use of artistic elements such as line, texture, color, and form in the creation of artworks in a way that renders visual stability.
What type of symmetry does a sponge have?
Most animals are bilaterally symmetrical with a line of symmetry dividing their body into left and right sides along with a “head” and “tail” in addition to a top and bottom. Only sponges (phylum Porifera) have asymmetrical body plans.
Does a sponge have Cephalization?
Sponges have no particular symmetry; they are not radially or bilaterally symmetrical. Cephalization means having a head. For humans and many other animals, our head is the part of the body that has the brain and most of the sensory organs. Cephalization only occurs in bilaterally symmetrical animals.
Is a starfish symmetrical?
A typical starfish has five-sided symmetry. With no clear head, the starfish can move in any direction, led by any one of its five arms.
Can humans touch starfish?
“Simply put, starfish absorb oxygen from water through channels on their outer body. You should never touch or remove a starfish from the water, as this could lead to them suffocating. “Sunscreen or the oil on our skin can harm sea creatures which is another reason not to touch them.”
What type of body cavity do starfish have?
Echinoderms also have a spacious coelom (an open, fluid-filled body cavity lined with tissue), large gonads, and (usually) a complete gut.
What kind of body symmetry does a starfish have?
radial symmetry
Why are starfish radially symmetrical?
Radial symmetry means that the body is a hub, like a bicycle wheel, and tentacles are spokes coming out of it (think of a starfish). As larvae, echinoderms are bilaterally symmetrical. As they mature, they become radially symmetrical. Most adult echinoderms live on the bottom of the ocean floor.
