Question

on what part of the frond are the sori located?

ACTIVITY 9: In angiosperms, fruits play an important role in seed dispersal. Plant biologists recognize different types of fruit, 11 of which are described in the table below. Dried fruits can be further classified as indehiscent (the fruit/pod does not split open when ripe) or dehiscent (fruits/pods split open when mature)." Examine the provided examples of fruits. Example Category Description Fruit Type Simple fruits Ovary wall and seed coat are fused, one seed; seed is Sunflower Achene attached at only one point to the ovary wall seeds Ovary wall is thin and fully fused to the seed at all Wheat Grain points, one seed. Dry fruits Ovary wall hard or woody but can be separated from Walnut Nut seed, one seed: may have an outer husk maturity Ovary has several cavities in cross-section, several to Cotton Capsule many seeds Bean pod Ovary has one cavity that opens along both sides, Legume many seeds Follicle Ovary has one cavity that opens along one side, many Milkweed seeds Ovary with one seed surrounded by very hard seed rhard seed Cherry Drupe coat, outer covering of seed formed from inner ovary fruit Mature ovary tissue soft and fleshy, surrounding Berry Fleshy fruits Berry flower tissue does not develop into fruit, many seeds (not hardened) Fleshy fruit develops in part from surrounding Apple Pome flower tissue (base of sepals and petals), ovary wall forms "core" around seeds, many seeds Compound fruits More than Multiple fruit Fruit formed from fused ovaries of many flowers Pineapple Aggregate fruit Fruit formed from several fused ovaries in one flower Blackberry Classify the following fruits using the following terms: simple vs. compound; dry vs. fleshy, indehiscent vs. dehiscent; fruit type (see chart above). 1. Pear: 2. Sunflower seed: 3. Nectarine: 4. Tomato: 5. Unprocessed rices 6. Strawberry: 7. Corn (kernel) "Science.jburroughs.org/resources/flower/fruit3.html

Answer 1

I hope the following table would explain the answer in a proper manner.

FRUIT	SIMPLE/COMPOUND	DRY/FLESHY	DEHISCENT/INDEHISCENT
PEAR	Simple Pome	Fleshy
SUNFLOWER SEED	Simple Achene	Dry	Indehiscent
NECTARINE	Simple Drupe	Fleshy
TOMATO	Simple berry	Fleshy
UNPROCESSED RICE	Simple grain	Dry	Indehiscent
STRAWBERRY	Compound Aggregate	Fleshy
CORN(KERNEL)	Simple Grain	Dry	Indehiscent

The explanation is given in the question itself.

Achene: Ovary wall and seed coat are fused and the seed is attached at only one point to the ovary wall
Grain: Ovary wall is thin and fused with the seed at all points
Drupe: Fleshy, Ovary with one seed surrounded by very hard sees coat
Berry: Fleshy, Mature ovary tissue, many seeds
Pome: Fleshy, Ovary wall forms core around seeds.

Aggregate: fruit formed from several fused ovaries. strawberry is a false fruit.
