Not every relation is a function. But every function is a relation. Function is just a part of relation.
The cubic function.
Range
A formula or graph are two ways to describe a math function. How a math function is described depends on the domain of the function or the complexity of the function.
The Mandelbrot graph is generated iteratively and so is a function of a function of a function ... and in that sense it is a composite function.
Difference between collenchyma and chlorenchyma
Mesophyll cells having chloroplasts are called chlorenchyma.
Chlorenchyma cells are a subtype of parenchyma cells specializing in photosynthesis. They are generally small, living when functional, and can take on varying shapes.
Chlorenchyma & palisade
cells in epidermis that contain chloroplasts
Chlorenchyma and palisade cells
Chlorenchyma and parenchyma
Chloroplast inside the chlorenchyma cell (generally in the leaves)
When millions of cells come together they form tissue When a group of cells unite to perform a specific function, it is called a tissue. For example photosynthetic tissue (chlorenchyma), storage tissue (parenchyma) and conducting tissues (xylem & phloem).
Chrolenchyma 1) In leaves and tender stems, parenchyma cells may contain chloroplast and in such case a parenchyma is called chlorenchyma. Aerenchyma 1) In aquatic plants, fairly large air cavities are present between the parenchyma cells; such a parenchyma is called aerenchyma.
The lamina is the expanded portion or blade of a leaf and it is an above-ground organ specialized for photosynthesis. For this purpose, a leaf is typically, to a greater or lesser degree, flat and thin, to expose the chloroplast containing cells (chlorenchyma) to light over a broad area, and to allow light to penetrate fully into the tissues.
