Propagation is defined as

• the union of an egg and sperm
• the process of increasing the numbers of a species
• a cheaper method of propagation than with seeds
• the only way to reproduce some species and cultivars

A seed consists of

• a root, stem, and flower
• root, seed coat, and endosperm
• seed coat, endosperm, and embryo
• embryo, cotyledons, and new plant

A type of stem cutting used where stock material is limited and has alternate leaves is a

• stem tip cutting
• cane cutting
• somple layering
• dingle-eye cutting

A cutting that is usually made from a large leaf plant with the veins split is

• split-cein cutting
• leaf petiole cutting
• terminal tip cutting
• tissue propagation

Grafting is

• type of sexual reproduction
• type of hybridization
• a method by which two plants are propagated
• a method of joining two parts of two different plants

The most common type of grafting is

• t-budding
• simple layering
• stem-tip propagation
• scion cut out of the stock plant

Tissue culture may be used for

• cloning
• disinfecting
• sexual reproduction
• sterilization

In tissue culture contamination may be a problem from

• air
• hands
• tools
• all of the above

To make a very inexpensive hood for tissue culturing, the recommended covering is

• 1-3 weeks
• 4-5 weeks
• 6-8 weeks
• 10-12 weeks
