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.
