Study Notes

Fruit Types

  • Fleshy fruits have the entire pericarp becoming soft and fleshy.
  • Simple fruits develop from a single ovary in a single flower.
  • Aggregate fruits develop from multiple ovaries of a single flower.
  • Multiple fruits develop from the ovaries of several flowers close together on a common axis.
  • Achene fruits are characterized by having one seed per fruit and not opening at maturity.
  • Caryopsis fruits are characterized by having hard, one-seeded fruits developed from compound ovaries.

Seed Structure

  • Cotyledons in a seed provide nutrition to the embryo during germination.
  • Monocot seeds have a shield cotyledon, an epicotyl covered by a sheath, and a hypocotyl covered by a sheath.
  • The primary function of the hypocotyl is to elongate and push the seedling out of the soil.

Germination

  • Hypogeal germination involves keeping the seed leaves below the soil surface during germination.

Seed Comparisons

  • Castor seeds are distinguished from bean seeds by their perisperm.
  • Corn seeds are classified as caryopsis fruits.

Plant Reproduction

  • The male reproductive structure in flowering plants is called the stamen.
  • Pollen grains are received by the stigma during pollination.
  • Fertilization is the process of an egg cell joining with a pollen cell in plants.
  • The ovary contains the ovule, where the egg cell is located.
  • Pollination is the process of transferring pollen grains from the anther to the stigma.
  • Sexual reproduction involves the fusion of gametes and a change in the number of chromosomes.

Test your knowledge on the classification of fruits based on their structure and development from a single ovary of a flower. Learn about simple fruits like berries and drupes, and understand the characteristics of each type.
