A Cell and Photosynthesis

Prepared By: CURRY P. AZARCON

A Cell

A cell is a tiny mass of protoplasm.

Yet it contain every bit of information

of a living plant.

The time the seeds germinates, the roots and shoots grows,

The flowers bloom, the fruits ripen.

And even to the time the plant wither

and eventually dies.

A cell in your body can measure much less.

Only about five thousandth of a milliliter.

Too small to be seen by the naked eye.

Yet it can accomplish much more than a microchip.

It is the basic unit of life.

Have known three distinct parts.

Nucleus, Cytoplasm and Cell Membrane.

All were necessary for cell to function well.

A Photosynthesis

The sun is the ultimate source of energy.

Through the process called photosynthesis,

Green plants and other producers,

Transform light energy into chemical energy.

The use of carbon dioxide and water during photosynthesis,

Results in the manufacture of glucose,

metabolic water and oxygen gas.

Glucose is the end-product of photosynthesis,

While oxygen is its by-product.

Photosynthesis is not a simple, one-step chemical reaction.

It may be divided into two phases.

Light-dependent phase or photochemical reaction,

And light-independent phase or dark reaction.
