Question

Draw three general figures showing the arrangement of the following flower parts  (pistil(s) or carpel(s), ovule(s), and ovary(-ies) on a receptacle or peduncle on plants producing the following fruits at table marked “A”.   pineapple,  blackberry, tomato. List the number of each female floral part (ex. - 5 ovaries fused each ovary containing 1 ovule). Explain how the fruit was formed during development including exocarp, mesocarp and endocarp. Assume that the pineapple and black berry contained only one seed in each fruit and the tomato contained 25 seeds in one ovary.

Answer 1

pineapple is a tropical plant with an edible multiple fruit consisting of coalesced berries, also called pineapples, and the most economically significant plant in the Bromeliaceae family.A fruit developing from a complete inflorescence is called a multiple or a composite fruit.

Blackberry: An aggregate fruit. Flowers with polycarpellary and apocarpous gynoecium give rise to a number of fruitlets as there are a number of free ovaries, each giving rise to one fruitlet. Sometimes, these fruitlets coalesce together appearing to be a single fruit but in many other cases, the fruitlets remain free from one another forming etaerio of fruitlets.
