Virus Structure & a quick glance into Virus Biology

virus structure

Virus are the smallest and ultra microscopic particles discovered by Iwanowsky in 1892. They are observed only by an electron microscope. They are so smaller that they can pass through bacterial filters. Further, they are obligate parasites on either animal or plant cells. That means they are inactive viable forms only inside the host and inactive once outside […]

5 Plant Growth Regulators | Their Role in Plant Growth

Plant Growth Regulators

Plant growth hormones are set of biochemical secretions inside the plant and its parts which regulate the growth, enlargement, multiplication of the tissue and cells. They control the rate and extent of plant growth starting from seed germination, after growth, flowering, fruit formation, ripening, wilting, falling of leaves etc. Based on these facts modern scientists have […]
