Biolistic Transformation Forage Information System

Biolistic transformation (particle bombardment) is based on the delivery of DNA into plant cells by high velocity gold or tungsten particles (Sanford, 1988). Because DNA delivery by particle bombardment is a physical process that does not depend on bacteria, it has become a versatile and effective transformation method for many species, particularly monocot plants (Wang and

Golgi Apparatus or Golgi Complex Functions and Definition

A Golgi apparatus is composed of flat sacs known as cisternae. The sacs are stacked in a bent, semicircular shape. Each stacked grouping has a membrane that separates its insides from the cell''s cytoplasm.Golgi membrane protein interactions are responsible for its unique shape. These interactions generate the force that shapes this organelle.The Golgi apparatus is very polar.

Pollination and fertilisation — Science Learning Hub

In a process called fertilisation, the two gametes join and their chromosomes combine, so that the fertilised cell contains a normal complement of chromosomes, with some from each parent flower. The fertilised ovule goes on to form a seed, which contains a food store and an embryo that will later grow into a new plant.
