    Total parasitic plants are those which are fully dependent on their hosts for growth and survival. Total parasitic plants are usually achlorophyllous. Cuscuta reflexa, Orobanche aegyptiaca, Striga asiatica etc. are the examples of total parasitic plants.
    Partial parasites are those which are partially dependent on their hosts. Partial parasitic plants are usually chlorophyllous therefore they are dependent on their hosts for water and nutrients only. Rest of the job is being done by their green leaves. Dendropthoe falcata, Viscum album, Santalum album etc. are the examples of partial parasites.

    At the cellular level,  the photosynthesis process takes place in cell organelles called chloroplasts. These organelles contain a green-coloured pigment called chlorophyll, which is responsible for the characteristic green colouration of the leaves.

    As already stated, photosynthesis occurs in the leaves and the specialized cell organelles responsible for this process is called the chloroplast. Structurally, a leaf comprises a petiole, epidermis and a lamina. The lamina is used for absorption of sunlight and carbon dioxide during photosynthesis.

    “Photosynthesis Steps:”

    • During the process of photosynthesis, carbon dioxide enters through the stomata, water is absorbed by the root hairs from the soil and is carried to the leaves through the xylem vessels. Chlorophyll absorbs the light energy from the sun to split water molecules into hydrogen and oxygen.
    • The hydrogen from water molecules and carbon dioxide absorbed from the air are used in the production of glucose. Furthermore, oxygen is liberated out into the atmosphere through the leaves as a waste product.
    • Glucose is a source of food for plants that provide energy for growth and development, while the rest is stored in the roots, leaves and fruits, for their later use.
    • Pigments are other fundamental cellular components of photosynthesis. They are the molecules that impart colour and they absorb light at some specific wavelength and reflect back the unabsorbed light. All green plants mainly contain chlorophyll a, chlorophyll b and carotenoids which are present in the thylakoids of chloroplasts. It is primarily used to capture light energy. Chlorophyll-a is the main pigment.
