The animals visit several flowers, so they The ovary bears ovules, which enclose the seeds, and consists of one or more carpels. It absorbs water and nutrients from the soil and sends it to the stem. Frequently small in size and making negligible demands upon their environment, seeds are eminently suited to perform a wide variety of functions the relationships of which are not always obvious: multiplication, perennation (surviving seasons of stress such as winter), dormancy (a state of arrested development), and dispersal. Citrus fruits, such as the grapefruit, also have membranous walls within the pericarp that separate the fruit into segments containing the pulp and seedsthey aren't very tasty but they have a purpose.

In the case of globe artichoke, the fleshy basal portion of the flower bud's bracts is eaten, along with its solid stem. Examples include branches of trees and runners on strawberries. The resulting seed has a broader genetic base, which may enable the population to survive under a wider range of environmental conditions. Examples include holly, ginkgo and pistachio. And then stem transports food in the form of glucose produced from photosynthesis from leaves to other parts such as roots and stems with the help of Phloem tissue. WebCorrect option is A) The part of the embryo above the cotyledons is called epicotyl. Like fleshy fruits, dry fruits can also depend on animals to spread their seeds by adhering to animal's fur and skin, this is known as epizoochory.

Why do you think seeds would not be formed On the top and bottom is a layer of thick, tough cells called the epidermis. Thus, a tomato and a cucumber are both fruit, as are peas and nuts.
