- Compound fruits may be aggregate fruits, in which one flower contains several ovaries, each of which develops into a small fruit. These small fruits are joined tightly together to make a larger fruit. An example of this is a raspberry. Each fleshy lobe in a raspberry is actually an individual fruit, but they are joined at their bases. Despite having the suffix "berry," aggregates cannot be berries, which are composed of a single ovary.
- Compound fruits may also be multiple fruits, in which several flowers, each with an ovary, develop into small fruits that are clustered or fused together into a larger fruit. An example of this is apineapple. Each section of a pineapple was an individual fruit from an individual flower, but they have fused to form the pineapple. Another example is the fig.
Grapes grow in clusters, but are not compound fruits. Each grape is grown from one ovary in one flower, and each grape remains an independent fruit.
A List of Compound Fruits
Monocots, or monocotyledons, are a class of the flowering plants, or angiosperms. Monocots are named for and recognized by the single cotyledon , or seed leaf, within the seed. The first green blade emerging from the seed upon germination is the cotyledon, which contains sugars and other nutrients for growth until the leaf is able to photosynthesize. Monocots comprise about 67,000 species, or one-quarter of all flowering plants. They include not only the very large grass family (Poaceae, 9,000 species), but also the orchid family (Orchidaceae, 20,000 species), and the sedge family (Cyperaceae, 5,000 species), as well as palms, lilies, bromeliads (including pineapple), and the Araceae, which includes skunk cabbage and philodendron. The angiosperms have traditionally been divided into monocots and dicots alone, but recent work has shown that while monocots form a natural evolutionary group, dicots do not, and so the angiosperms are now grouped into monocots, eudicots , and basal angiosperms. In addition to the single cotyledon in the seed, monocots can be recognized by the arrangement of vascular tissue in the stem. Vascular tissue includes xylem , used for water transport from the roots, and phloem , which carries sugars and other nutrients from the leaves to other tissues throughout the plant. Unlike other angiosperms, whose vascular tissue is arranged in rings around the periphery, the vascular bundles of monocots are scattered throughout the stem. One consequence of this is that monocots cannot form annual rings of hardened tissueâ€”woodâ€”and so are limited in the strength of their stems. Nonetheless, some monocots, notably the palms, do attain significant height. Leaves of monocots have parallel veins, as seen in grass. The roots of monocots also differ from other flowering plants. In monocots, the first root to emerge from the seed dies off, and so no strong, central tap root forms. Instead, monocots sprout roots from shoot tissue near the base, called adventitious roots. The familiar fibrous root system of grasses is an example of this rooting pattern. Many monocots form bulbs, such as onion, gladiolus, and tulips. These are not root structures, but rather modified stems, made of compact leaves. This can be easily seen in the layers of the onion. Most monocot flowers have flower parts in sets of three, so that there may be three or six petals, for instance, along with three egg-bearing carpels and pollen-bearing stamens in some multiple of three. The pollen grains of monocots have a single slit, or aperture, which splits open to allow the pollen tube to grow during fertilization . In contrast, the pollen grain of eudicots has three apertures. Orchid flowers are among the most beautiful and complex of all flowers, due in part to their long and specialized relationship with specific pollinators. Some orchid flowers have evolved to resemble the female of the bee species that pollinates them, luring the male in to attempt copulation. During this process, the pollen, all of which is retained in a single, sticky mass, is transferred to the male bee, who will carry it to the next flower in another fruitless attempt to find a mate. In contrast to the showy orchids, grass flowers are rather simple and dull, in keeping with the absence of any need to attract insects. Grass flowers are suspended at the tip of the plant, where wind can carry the pollen away to land on the female flower of a neighboring plant. Three grassesâ€”corn, wheat, and riceâ€”provide the vast majority of calories consumed by humans throughout the world. Their seeds, called grain, are rich in carbohydrates and contain some protein and vitamins as well. see also Angiosperms; Eudicots; Evolution of Plants; Flowers; Grain; Grasses; Leaves; Roots; Seeds; Shoots Richard Robinson Raven, Peter H., Ray F.

Answers:Deadly Nightshade (Solanum Nigrum) Oleander (Nerium oleander) Holly (Ilex sp.) Azealea (Rhododendron) Castor Oil Plant (Ricinus communis) em Lantana and Zamia Palm too I hope this is what you are looking for, these are all poisonous plants with inedible fruit for humans.
Answers:Pumpkins are dicot, their leaves are prickly as a 'defense mechanism' to ward of any creature that might want to eat the fruit. They tend to grow and extend, the roots grow into whatever surface it can and has vines that coil around surrounding environment. ( i know this because we have pumpkins growing in the backyard and the roots are wrapped around our porch swing) You could draw a close up of a pumpkin leaf, and the way the roots grow. Here are some other fun facts that might help: Bulbs In some monocots, leaf bases grow to form bulbs, underground organs used for food storage. They can be identified from the series of leaf bases fitting inside each other, with a central shoot apical meristem. Stem Tubers In some dicotyledon plants, stems grow downwards into the soil and sections of them grow into stem tubers, also used for food storage. They are identified as their vascular bundles are arranged in rings reminiscent of stem bundles. Storage Roots These roots are swollen with stores of food, identified by the central location of vascular tissue. Tendrils These narrow outgrowths from leaves rotate through the air until they touch a solid support to which they attach, allowing the plant to climb upward
Answers:There's a very easy way to tell whether a plant is dicot or monocot. Look at the veins in the leaf. If they branch out like a tree (dendritic pattern) they are dicots. If the veins are parallel, like the veins in a blade of grass or a corn leaf, it's a monocot. The first link is a pic of an oak leaf, which is a dicot. The second link is a pic of the parallel veins of a corn leaf. Also, dicot flowers tend to have flower parts in multiples of four or five (petals, stamens, sepals). Monocot flowers tend to have flower parts in multiples of threes.
Answers:Monocot is short for monocotyledon which means when the seed germinates one leaf emerges as compared to two with the dicots. Monocots are characterized by parallel venation in the leaves, fibrous root system and flowers with all parts in a multiples of three. Where as dicots have netted venation, typically have a tap root and have flowers with the parts in multiples of four or five. Grasses, palm trees, lilies, iris and orchids are examples of monocots.
