Berry developed from what type of ovary?
either superior or inferior.
what are some examples of the fruit type berry?
Guava, kiwi, cranberry, tomato, blueberry.
describe the fruit berry based on the layers:
The exocarp is thin, both the mesocarp and endocarp are fused and fleshy. seeds are numbers.
Describe the fruit plant drupe based on the fleshy layers:
Has a pit on the inside. Exocarp is relatively thin, and the mesocarp is either fleshy or fibrous. The endocarp is stony and encloses a single seed.
Examples of the fleshy fruit Drupe:
Cherry, Olive, Coconut, Peach and mango
Describe the fleshy layers of the fleshy fruit pome:
The receptacle that surrounds the ovary also becomes part of the fruit. the exocarp is thin, the mesocarp is fleshy, and the endo carp is thin.
Examples of the fleshy fruit pepo is:

apple,pear, quince, etc.
Describe the fleshy layers of the fleshy fruit pepo:
The receptacle that surrounds the ovary also becomes part of the fruit, making it an accessory fruit.
The exocarp is thick and forms a hard rhind, the mesocarp and endocarp are fleshy and the seeds are numerous.

both.
superior or inferior
most common ovary position for the drupe
both.
superior or inferior
most common ovary position for the pome

superior
What is the fruit type for a single flower with many ovaries
aggregate fruit
What flower type is is derived from many flowers in an inflorescence?
multiple fruits
Define a fleshy fruit
The entire pericarp or any one or more of the three layers remain fleshy, resulting in a fleshy fruit.
Define a dry fruit
The entire paricarp is dry at the time of maturity.
Describe the fleshy layers of the fleshy fruit hesperidium:
The exocarp is leathery, the mesocarp is spongy (usually white) and the endocarp is thin, with juice filled hairs.
Give an example of a hesperidium:
Oranges, grapefruits, any citrus type fruit.
What is an aggregate fruit?
A conglomeration of several individual units made of berries, dupes, or achenes that make up one single fruit.
What type of ovaries are most aggregate fruits from?
Superior ovaries.
What is multiple fruit?
a single fruit but formed as a result of the union of the mature ovaries, the surrounding flower parts, the receptacle, and the and the central axis of the inflorescence.
What type of ovaries are most multiple fruits from?
The position of the ovary is not critical. both are present (~equally)

most members of mustard family.
What are some types of dry indehiscent fruits?
- achene
- caryopsis or grain
- nut
- samara

What are dry, indehiscent fruits?
The pericarp will not split open but moves along with seeds during dispersal.
What is the characteristic(s) of a achene?
A single-seeded fruit with a dry, loose pericarp.
What is the characteristic(s) of a caryopsis or grain?
A single-seeded fruit with the pericarp firmly fused with the seed coat.
What is the characteristic(s) of a nut?
A single-seeded fruit with the entire pericarp forming a hard, stony loose layer surrounding the seed.
What is the characteristic(s) of a samara?
a modified achene, pericarp developed into a wing.
What is the characteristic(s) of a schizocarp?
composed of two units, each with its own single seed called a mericarp, which separate easily from each other in the middle.
