Lime raises the soil pH level so that the soil becomes more:

• acidic

• alkaline

• eroded

• porous

The propagation method where a plant is separated into smaller parts is:

• division

• grafting

• air layering

• tip layering

Which is considered a biotech method of plant propagation?

• cuttings

• grafting

• sowing seed

• tissue culture

Tissue culture may be used for:

• producing genetically identical plants

• disinfecting greenhouse structures

• sexual reproduction in floral crops

• sterilization of soil products

Sexual reproduction in plants is the propagation of plants by:

• flowers

• roots

• seeds

• stems

The three primary nutrients supplied in a complete fertilizer are:

• carbon, hydrogen, and oxygen

• nitrogen, phosphorus, and potassium

• calcium, magnesium, and sulfur

• carbon, nitrogen, and sulfur

Sulfur is used to lower soil pH so that the soil will become more:

• acidic

• alkaline

• eroded

• porous

The purpose of a seed coat is to:

• store food

• store genetic material

• protect the seed

• filter light

The primary function of the root is to:

• make sure that the plant will grow

• anchor the plant and supply water and nutrients

• ensure that the plant can be propagated

• hold up the stem of the plant and provide propagation material

The primary function of the stem is to:

• produce flowers

• produce fruit

• anchor the plant

• support other plant functions
