The Function of Leaves

Leaves collect energy in the form of sunlight and provide it to the rest of the plant. This energy is necessary in the survival of the plant. They also are used to store food, water, and minerals as well.

Where are leaves located?

Although there are many different plants with different types of leaves, one thing is the same for all of them: Leaves are located on the outside of the plant (either on top or to the sides) so that they can collect sunlight.

Organization of Leaves on the Plant

Plant leaves are

rganized/oriented throughout the

plant so that they do not block the sun from one-another as well as having the wide sides facing upwards to collect more sunlight. All in all, leaves are the most exposed part of the plant in order to retrieve the most sunlight.

Microscopic Structure of Leaves

Outer protective layer of cells are tightly comprised in the

epidermis

Small group of collenchyma cells exist beneath epidermis

and have stronger cell walls

The leaf tissue between the epidermis is called the

mesophyll, containing the vascular tissues which are composed of veins and leaf traces

Cells within the vascular tissue consist of the xylem and

phloem cells

2 sections of mesophyll: spongy and palisade parenchyma

How the Microscopic Structure Works

Cells on epidermis secrete a waxy layer called the

cuticles, which helps the leaves retain water

The collenchyma cells provide additional support
The guard cells beside the stromata modify their size in
rder to reduce water loss and regulate gas exchange
The vascular tissues transport water and minerals to diff.

parts of the leaf

Parenchyma sections contain the chloroplasts for

photosynthesis, these cells have thin, flexible walls
