Guard cells are specialized cells in the epidermis of leaves that control the size of stomata. They are responsible for regulating the opening and closing of the stomatal pores to allow gas exchange and regulate water loss.
Ferns differ in sizes and shapes from tiny moss-like sizes to house-gutter sizes. They can be elongated or spiral. But most ferns have elongated compound leaves.

One of the easiest ways to control portion sizes in to invest in a simple kitchen scale. This allows a more exact measuremnt of determining serving sizes and counting calories.
Because They Are All In Different Progresses of Growing.
Most parts stores can look them up. Sizes & opening temps differ for different engines.
The combination of shapes and sizes of grains in a material is known as its grain structure. This grain structure can vary depending on the type of material and the processing techniques used. It can influence the material's mechanical properties, such as strength, ductility, and toughness.
Huge. I don't know the exact sizes, but they are very large. Take a look at pictures of the bulk carriers that are used on the Great Lakes. (I see them every day!)
Leaves come in various sizes, ranging from tiny micro-leaves that can be just a few millimeters across to large leaves like those of the giant sequoia, which can exceed three feet in length. The size of a leaf often depends on the plant species, its environment, and its role in photosynthesis. For instance, larger leaves may be more efficient in capturing sunlight in dense forests, while smaller leaves can reduce water loss in arid conditions. Overall, leaf size is a key adaptation to help plants thrive in their specific habitats.
