OBJECTIVES By the end of the lesson, students to be able to a) define farm animals b) give examples of farm animals c) state the importance of different farm animals. What are Farm Animals? Farm animals are animals that are raised and kept for agricultural purposes. They include cows, chickens, pigs, sheep, camels, etc. Food – farm animals such as cattle, goat, sheep are used as food through the provision of meat and milk while poultry provides egg and meat. Fish is another source of protein Income – Farm animals are sold to generate income. Employment – Many people take up production of farm animals as full time employment. Foreign Exchange – Surplus production of farm animals can be exported...

OBJECTIVES By the end of the lesson, students should be able to a) State the meaning of nursery b) Mention nursery practices c) Explain how to construct vegetable beds d) Explain how to transplant crops from the nursery. The Meaning of a Nursery A nursery is a place where seedling (young crops) are intensively raised and taken care of before they are transplanted to the main field. A nursery is also a place where plants are propagated and grown to usable size. A nursery bed is a specially prepared portion of land put aside for raising seedlings. It acts as a temporary home for young plants until they are eventually planted in a permanent garden....

Monocotyledons Cotyledon means natural leaf borne of a seed of a plant, it is also known as seed leaf. Monocotyledons also are known as monocots are plants with only one cotyledon or seed leaf. Examples are cereals like maize, sorghum, wheat, millet, barley, and grasses e.t.c Features They possess one seed leaf, fibrous root system, parallel aeration, long and narrow leaf, non scented dull flower e.t.c Dicotyledons The dicotyledons, also known as dicots, is one of the two groups into which all the flowering plants or angiosperms were formerly divided. The name refers to one of the typical characteristics of the group, that is, the seed typically has two embryonic leaves or cotyledons. There are about 200,000 species within this...

Introduction In this second part of the study on forms of crop plants, we shall study the meaning of pollination and fertilizers. Pollination Pollination is the process by which pollen is transferred from the anther (male part) to the stigma (female part) of the plant, thereby enabling fertilization and reproduction. This takes place in the angiosperms and flower-bearing plants. What is the function of pollination? Like humans, many plants require a male element and a female element to “breed” or produce a new seed. The difference is that plants possess both the male element and the female element in the same flower. The male is the anther which produces a powder or dust called pollen and the female is called...

Introduction In this part, we study the Root/Shoot and Structure and Function of each part of a flowering plant. Your basic vascular plant parts are roots, shoots, stems, and leaves. Of course, there’s a wealth of variety within these types or parts, but it boils down to those four. Each part has distinct functions. Together, these parts reflect how vascular plants evolved to inhabit two distinct environments at the same time: the soil and the air. Why would plants do such a thing? The soil offers water and vital minerals. The air offers carbon dioxide and the energy of sunlight. To forge the successful lifestyles they enjoy today, plants evolved systems to tap into all these resources, both above and...
