Agriculture is defined as the cultivation (or planting) of crops and rearing of animals for man's use.
The early man lived by hunting and gathering fruits. This made him move from place to place in search of foods like fruits, nuts and berries. He gathered so much at a time that he could not eat all the fruits he collected. As a result, he threw the rest away along the foot paths he had made in the bush and his camping sites.
Please read on the definitions and meanings of various agricultural terms here.
During the rainy season, these seeds germinated and grew into a large number of fruit plants around the camping ground. These fruits got matured and the early man harvested them for food.
At first, the early man began to plant the seeds without sorting; but as time went by, he started choosing better seeds for planting. Also, he began hunting for animals in the bush with the use of club, bow and arrow. Some of these animals were tamed and reared as domestic animals.
Again, he started growing food to feed these animals, making him become an animal farmer. After some period of time, he became advanced in farming methods.
Please read on agricultural tools and their uses.
Provision of food for man through the cultivation of crops and rearing of animals. Food is one of the most basic need of all human beings.
Provision of shelter which protects us from adverse weather conditions. For example, wool is used in making protective clothes while timber (or wood) is used in the building of houses. Please read on hardwood and softwood here.
Provision of a clothing through the processing of raw materials like cotton, hemp, flax (linen), jute, kapok, silk and wool. Clothes gives comfort, protects, cover and beautifies our body.
Provision of employment opportunities through agribusiness like animal husbandry, poultry, aquaculture, snailery, bee keeping (apiculture), etc. It also act as employer of labor; for example, agricutural machines operators, agricultural teachers in schools, etc.
Provision of raw material for industries. Examples of agricultural raw materials include rubber, hides, skin, cotton, groundnut, oil palm, cocoa, sugarcane, timber, milk, melon, etc. Please read on mixed farming, its advantages and disadvantages here.
Provision of foreign exchange to individuals and nations. This is achieved through the selling of agricultural produce to other nations, and as a result earning foreign currencies in the process.
Some agricultural products can also serve as herbs and drugs. Examples are moringa tree, coffee, pawpaw seed, avocado seed, miracle leaf, bitter leaf, etc.
Agriculture has brought an advancement in science and technology through the development of agricultural machines like tractors; and advancement of food and fruit qualities (or yield) through genetics and agricultural engineering.

Amazing facts in Agricultural Science
Cows technically have one stomach, not four. However, a cow's stomach has four compartments. These are: rumen, reticulum, omasum and abomasum
Peanuts are legumes and not nuts
Although plants neither see nor hear, they can recognize their siblings and even give them preferential treatments
Squirrels do plant more trees (through their actions) than an average human in their lifetime. They often hide their acorns and nuts underground and forget about them
Cows have got the ability to walk up stairs, but not down stairs
A group of cows is called a team, drove or herd.
People just prefer to call them herd
Notable points in Agricultural Science
Below are characteristics of gymnosperms:
Their seeds have cones that protect them.
Sepals and petals aren't present in their cones.
Stigma and style are absent.
They do not produce fruits. Only seeds are formed.
Companion cells are absent.
Sporophyll form the cones.
Anther and filament are absent.
The ovules are not present in the ovary.
Gymnosperms do not possess flowers.
Please read on the anatomical differences between gymnosperms and angiosperms here
The flower is the reproductive organ in plants' sexual reproduction. In order to achieve a successful sexual propagation or reproduction in plants, the floral parts of the flower are utilized.
The floral parts of a flower consists of the followings:
Sepals
Petals
Stamen
Carpel
The stamen is male portion of a plant. It consists of the anther and filament.
The carpel (or pistil) is the female portion of the plant. It consists of the stigma, style and ovary.
An organism will be considered a pest if it does one of the followings:
Attack crops and eat its seeds, roots, stem, leaves and flowers. Examples are locust and grasshoppers.
Cause damage to stored food, fruits or other agricultural produce. Some may even urinate or deaficate on these products. Examples are rodents, cockroaches and mice.
Attack and kill farm animals like goats, sheep and cattle. Examples are foxes, wild cats and snakes.
Act as disease vectors. A vector is an organism that carries parasite and other disease causing organisms, without being affected; but when they introduce the parasites into their host, such host becomes infected with disease. Examples of vectors are rodents and mosquitoes.
Below are the classification of crops based on their uses:
Oil crops
Vegetable crops
Latex crops
Drug and Medicinal crops
Beverage crops
Fibre crops
Fruit crops
Root and Tubers
Legumes
Spices
Cereals
All crops are plants but not all plants are crops. Below are some instances:
Weeds are considered as plants, not crops.
Parasitic plants are not necessarily crops. Examples of parasitic plants include mistletoe, corpse flower and striga.
Carnivorous or insectivorous plants are not necessarily crops. Examples are sundew, venus flytrap and pitcher plant. The image below shows a carnivorous plant (venus flytrap).
Meanwhile, always understand that all crops are plants, and they are grown for food, money or something beneficial.
