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.
Area is the number of square units enclosed by the 2D shape. Perimeter is the distance around the outside of a 2D shape. Two dimensional shape with four sides and one pair of parallel and congruent sides.
