In general, a flower has four whorl components, namely the calyx, corolla, gynoecium and androecium.
Step by step solution
01
Introduction
Flower is the reproductive organ of an angiosperm. Angiosperms reproduce sexually with the help of flowers. Flowers also help in attracting pollinators for pollination by producing nectar as a reward for the pollinators. A flower in general has four whorl components: calyx, corolla, gynoecium and androecium.
02
Explanation
The calyx and corolla are the non-reproductive parts of the flower. They are called the accessory parts of the flower, that performs different functions.
The flower's outer whorl is called the calyx. It is made up of sepals, which are tiny leaves located at the base of flowers. Calyx provides protection to the flower while it is in bud stage and they perform photosynthesis as well.
The second whorl of the flower is called corolla, that is made up of petals. Petals are vividly coloured and scented to attract pollinators.
03
Explanation
The gynoecium(carpel) and androecium(stamen) are reproductive parts of the flowers that is involved in the reproduction process.
The carpel is the flower's fourth whorl, and it is found in the centre. The carpels house the pistil, the female reproductive component of the flower. It includes the ovary, style, and stigma. The egg, or ovule, is found in the ovary. After fertilisation the ovary becomes the fruit and the ovules become the seed, which are guarded and enclosed by the fruit. The stigma is supported at the tip of the ovary by a vertical structure called the style. Pollen that has been dispersed, sticks to the stigma and travels down the style to the ovary.
The male reproductive part of the flower is the stamen, and makes up the third whorl of the flower. It consists of an anther and a slender stalk supporting the anther, called filament. Pollen grains, which contain the male gametes are produced and stored in the anther.

The three main factor markets are the labor market, the capital market, and the land market, which refers to all natural resources. The input market supplies the resources needed to make finished products. The output market buys and uses the finished products.
economy, households and businesses (firms) use markets to exchange money and products. Households own the factors of production and consume goods and services. Households pay firms for goods and services. Firms supply households with goods and services.
The circular flow of income illustrates the links between income and spending in an economy. In its simplest form, revenue earned by firms by selling their output ultimately flows to households, which spend this income on the output produced by firms.
Households sell land, labor, capital, and entrepreneurial activity in exchange for money, which in this case is called income. Households are buyers in the market for goods and services. Households exchange income for goods and services. Businesses are sellers in the market for goods and services.
Answer and Explanation: Factors of production have various payments. For instance, the income for land resources is known as rent.Secondly, an entrepreneur earns profit, capital resource owner earns interest, and finally, labor payment is wages.
The factors of production are the inputs used to produce a good or service in order to produce income. Economists define four factors of production: land, labor, capital and entrepreneurship. These can be considered the building blocks of an economy.
The external sector and foreign sector are all terms used to describe the overseas sector. The four-sector circular flow model consists of individuals, businesses, the government, and overseas. The financial sector is not included.
The role-players in the economy include households, business, government and the foreign sector. These participants are involved in the processes of production, consumption and exchange.
In capitalism, the factors of production are most often controlled by business owners and investors. In socialist systems, the government exerts greater control over the factors of production.
The purpose of capital goods is to help produce other products. They are meant to be used for production, while consumer goods are bought for personal and final consumption. Businesses, companies, and manufacturers buy capital goods. Consumer goods are bought by consumers.
Globalization allows companies to find lower-cost ways to produce their products. It also increases global competition, which drives prices down and creates a larger variety of choices for consumers.
Types of Accounting Transactions based on the Exchange of Cash. Based on the exchange of cash, there are three types of accounting transactions, namely cash transactions, non-cash transactions, and credit transactions.
The factor market describes the resource markets where businesses purchase what they required for production. For instance, when a bakery purchases wheat from a farmer, the wheat will be used for some production as it serves as raw materials in the bakery.
Accordingly, the Manual distinguishes only three basic types of transaction, i.e., transactions in goods and services, transfer payments, and transactions in financial items.
