Aggregate fruit

An aggregate fruit, or etaerio, develops from a flower with numerous easy pistils. An example is the raspberry, whose simple fruits are termed drupelets since each is like a small drupe emotionally involved to the receptacle. In some bramble fruits (such as blackberry) the vessel is elongated and part of the ripe fruit, making the blackberry an aggregate-accessory fruit. The strawberry is also an aggregate-accessory fruit, only one in which the seeds are enclosed in achenes. In all these examples, the fruit develops from a single flower with several pistils.

Types of Fruit


Fruits are so varied in form and development, that it is difficult to devise a classification scheme that includes all known fruits. Many common terms for seeds and fruit are incorrectly applied, a fact that complicates understanding of the terminology. Seeds are ripened ovules; fruits are the ripened ovaries or carpels that contain the seeds. To these two basic definitions can be added the clarification that in botanical terminology, a nut is a type of fruit and not another term for seed.[2]

There are three basic types of fruits:

Simple fruit
Aggregate fruit
Multiple fruit

Fruit, vegetable

Since “vegetable” is not a botanical term, there is no negation in referring to a plant part as a fruit while also being considered a vegetable (see diagram). Given this general rule of thumb, vegetables can also embrace leaves (lettuce), stems (asparagus), roots (carrots), flowers (broccoli), bulbs (garlic), seeds (peas and beans) and botanical fruits such as cucumbers, squash, pumpkins, and capsicums (bell peppers). Botanically, fruits are reproductive organs (ripened ovaries containing one or many seeds), while vegetables are vegetative organs which keep up the plant.

The question "is it a fruit, or is it a vegetable?" has even found its way into the United States Supreme Court, which ruled generally in Nix v. Hedden, 1893, that a tomato is a vegetable for the purposes of 1883 Tariff Act, even though botanically, a tomato is a fruit.
Commercial production of vegetables is a division of horticulture called olericulture

Fruits

The term fruits has different meanings depending on circumstance. In botany, a fruit is the grown ovary—together with seeds—of a flowering plant. In many varieties, the fruit incorporates the grown ovary and surrounding tissues. Fruits are the means by which peak plants disseminate seeds. when discussing about fruit as food, the term usually refers to those plant fruits that are sweet and fleshy, examples of which include plums, apples and oranges. However, a great many common vegetables, as well as nuts and grains, are the fruit of the plant type they come from. The term "fruit" has also been incorrectly applied to the seed-containing female cones of many conifers.

Sports

Perfect is a physical phenomenon known to athletes? When a person exercise at a certain level for a certain period over a certain number of weeks, their body will raise its metabolism to a higher level - it will continue at this level as long as a certain amount of exercise is performed each couple of days. This result was discovered by Dr. Kenneth H. Cooper for the United States Air Force in the late 1960s. Dr. Cooper coined the term "Training Effect" for this.

The measured effects were that muscles of respiration were strengthened, the heart was strengthened, blood pressure was infrequently lowered and the total amount of blood and number of red blood cells increased, making the blood a more competent carrier of oxygen. VO2 Max was amplified.

The exercise necessary can be talented by any aerobic exercise in a wide diversity of schedules - Dr. Cooper found it best to award "points" for each amount of exercise and require 30 points a week to preserve the Training Effect.

As it would be foolish for someone unconditioned to challenge 30 points in their first week, Dr. Cooper instead recommends a "12-minute test" followed by adherence to the appropriate starting-up schedule in his book. As always, he recommends that a physical exam should lead any exercise program.
