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.
The perimeter is defined as the distance around the outside edge of a two-dimensional shape. The perimeter of a circle or an ellipse is referred to as the circumference. The word perimeter comes from the Greek word peri, which means around, and the Greek word meter, which means measure.. The perimeter can also be easily defined as the outline of an object.
