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.

Most parts stores can look them up. Sizes & opening temps differ for different engines.
Broad leaves, also known as broadleaf leaves, are typically flat and wide, which allows for efficient photosynthesis by maximizing surface area for sunlight absorption. They are commonly found on deciduous trees and shrubs, enabling them to capture more light in temperate climates. Broad leaves also tend to have a thicker structure, which helps in retaining moisture and can provide shade to the ground beneath. Additionally, they often display a variety of shapes and sizes, contributing to biodiversity in ecosystems.
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.
During the Jurassic period, the leaves of cycads resembled those of modern ferns and palm trees, characterized by their feather-like, pinnate structure. These leaves were typically thick, leathery, and often had a glossy appearance, helping the plants to withstand the warm, humid climate of the time. The cycads were among the dominant plants during this era, showcasing a diverse range of leaf shapes and sizes. Overall, their leaves contributed to their adaptation in various environments throughout the Jurassic landscape.
