Side stems affect plant vigor. As a tomato grows, side shoots, or suckers, form in the crotches, or axils, between the leaves and the main stem. If left alone, these suckers will grow just like the main stem, producing flowers and fruit. Suckers appear sequentially, from the bottom of the plant up.
The perimeter of a two-dimensional shape is the total distance around the shape, or the sum of the length of its sides. By definition, a square is a four-sided shape with four straight sides of equal length, and four right (90Â°) angles.
Perimeter is the limit of any given geometric figure. Circumference is just the name given to a circleâs perimeter, in other words, the circleâs limit, its edge. The reason for this is because the perimeter is, by definition, the sum of the lenght of every side of any given geometric figure. A circle has either no sides, or [math]n[/math]number of sides, so its perimeter has to be treated differently.
