Write an essay about the adaptations of green plants for photosynthesis

Extracts from this document...

Introduction

Write an essay about the adaptations of green plants for photosynthesis Photosynthesis is the metabolic pathway by which the inorganic compounds water and carbon dioxide are converted into carbohydrates using light energy, which is absorbed by chlorophyll. Plants need to be adapted so that maximum light energy is absorbed and therefore maximum photosynthesis occurs. Plants have adapted in order to be able to survive in many different climates such as high temperatures and humid conditions. Leaves play an important part in photosynthesis, as they are the first part of the plant, which is exposed to the light energy from the sun. ...read more.

They are also tightly packed together to ensure that no light energy is lost. The palisade cells and the upper epidermis contain high number of chloroplasts to ensure that maximum light has been reabsorbed. These chloroplasts are mobile within the cytoplasm this helps to ensure that maximum light is absorbed. The leaf grows at right angles to ensure the largest surface area is exposed to the sunlight. Another adaptation of the plant known as phototropism means that the plant will grow towards the light. Leaves are broad and flat to provide a large surface area and to provide a short path for the light to travel. ...read more.

Conclusion

The role of the chloroplast is to absorb light energy from the sun and to convert it into chemical energy. Many different pigments are found in plants, they all absorb different wavelengths of light this ensures that as much light energy as possible is absorbed. Chloroplasts have an envelope in their membrane, which allows carbon dioxide to diffuse into the plant and allows oxygen to diffuse out of the plant. Oxygen is a waste product of photosynthesis. Chloroplasts have a membrane system, which is made up of grana to form thylakoids. These provide a large surface area for the photosynthetic pigments. As it can be seen plants, have to be well adapted to make sure that they achieve the maximum rate of photosynthesis. Name: Reena Harsiani Subject: Biology Tutor: Tina Short ...read more.
