A plant structure that resembles a fruit but is not derived from a flower or flowers

• 1.Flowers are usually large, brightly-colored and scented to attract
• insects. If the flowers are small they may group together to form
• conspicuous inflorescences.
• 2.Nectar is often present to attract insects.
• 3.Pollen is fairly abundant. Pollen grains are large sticky and heavy, usually with rough surfaces so that they can readily cling onto the insects bodies.
• 4.Stamens may not be pendulous.
• 5.Stigmas are usually not feathery and do no protrude. They are sticky
• so that pollen grains settling on them are not easily displaced.
• 6.Nectar guides may be seen on the petals.

• the result of genetic breeding where the dominant genes from one parent plant are used to suppress the undesirable recessive genes of the second parent plant.
• The resulting seedlings will be larger and stronger than either of the
• parents as well as generally showing better disease resistance.

• Tepals are elements of the perianth, or outer part of a flower, which include the petals or sepals.
• The term tepal is more often applied specifically when all segments of
• the perianth are of similar shape and color, or undifferentiated, which
• is called perigone.

• The
• Anthers contain pollen sacs. The sacs release pollen on to the outside
• of the anthers that brush against insects on entering the flowers. The
• pollen once deposited on the insect is transferred to the stigma of another
• flower or the same flower. The ovule is then able to be fertilised
• The stigma Is
• covered in a sticky substance that the pollen grains will adhere to.

the tendency of a fluid, usually water, to pass through a semipermeable membrane into a solution where the solvent concentration is higher, thus equalizing the concentrations of materials on either side of the membrane.

• The growth in width of stems and roots in
• plants, resulting in more thicker, sturdier tissues that can support the
• growing plant.
