Adaptations Of A Leaf
Leaves are made of different components. The leaf has a mesophyll layer
where most of the photosynthesis occurs. It has xylem and phloem which
help to transport the substances around the plant. It also contains epidermal
tissue which covers the whole leaf.
Taking these graphs into account, you can artificially control the environments
for plants. This can be done in a number of ways:
A greenhouse can be used to trap the suns heat in order to make sure that
the temperature is no longer the limiting factor.
To make sure light is not the limiting factor, artificial lights can used to ensure
Carbon dioxide can also be an issue, however this can be solved using a
paraffin heater which provides carbon dioxide
A leaf has many parts. The top of the leaf is known as the waxy cuticle, which
protects the leaf and prevents water loss.
The upper part of the leaf is where the sunlight hits. Therefore the upper part
of the leaf has many palisade cells (for photosynthesis). These palisade cells
have many chloroplasts and look like the plant cell drawn above.
Carbon dioxide enters the plant through small pores in the leaves called
stomata. Guard cells control these pores and help maintain the conditions
within the plant and help it adapt to the conditions outside for example
The lower part of the leaf cell is called the spongy layer. It has many gaps,
which allows the carbon dioxide to move around and reach other cells.
Water is absorbed from the ground. The roots have root hair cells, which are
adapted to getting the maximum amount of water from the ground. There
are long and thin , which allows them to reach the maximum area, also they
have very thin walls thus reducing the diffusion distance for water.
