Lesson Plan of Plants
Students` Learning Outcomes
- After studying this lesson, students will be able to:
- Comparing flowering and non-flowering plants
Science Process Skills
Observing, Classifying, Communicating, Inferring, and Predicting
Information for Teachers
- There are many types of plants and they are divided into different categories. Today you will get to know one of the most relevant: plants without flowers and plants with flowers.
- The classification of plants can be done according to different characteristics; for example, its size, its duration, its properties, its usefulness, its way of reproducing and the presence or absence of fundamental parts.
- In this note, we will talk about plants according to their presence of flowers: plants without flowers vs. plants with flowers. We will tell you everything about its characteristics and its types. In addition, we will give you some examples. If you want to know more classifications, we invite you to read what types of plants there are.
Characteristics of non-flowering plants
- As its name says, plants without flowers are those that do not produce flowers. Mainly, these are characterized by their type of natural reproduction, since they do not produce seeds or fruits. Plants without flowers reproduce by means of spores, which are defined as reproductive plant cells that do not need fertilization, since they have the ability to generate new plants through cell division.
- The spores of plants without flowers are located on the opposite part of the leaf that does not receive light, which is, the underside, and they wait until they are mature enough to fall to the ground. If the soil meets the necessary conditions for the reproduction of plants, such as humidity and temperature, a plant without flower will grow identical to the original.
- Plants without flowers are characterized by, for the most part, having a deep green color, strong stems and large leaves to absorb as much light and nutrients as possible from the environment. However, this can vary by species.
- On the other hand, we tell you that plants without flowers could be one of the first living beings on earth, even before people. In forests, these types of plants tend to abound. Likewise, its growth, development and reproduction are favored in places with high humidity.
Material / Resources
Writing board, chalk / marker, duster, flashcards of different plants, textbook
- Students have studied about the classification of animals. Ask some questions about their previous knowledge:
- What do you mean by classification? Why we do classify animals?
- Can we classify plants?
- Now students will learn the basic scientific classification of plants into flowering and nonflowering plants..
- Arrange the students into groups.
- Give pictures of different plants.
- Ask each group to observe the plants shown in the pictures. Discuss the structure of different parts of the plants within the group. Also share your own knowledge about these plants within group.
- Students will share important points noted by the group to the whole class (one member from each group will present the points). Initiate and guide the class discussion through interactive set of questioning:
- How are plants different from one another?
- Because they are different in size
- Because they are different in shape
- They produce different fruits
- Can we classify them?
- What can be the basis?
- Prepare charts from the following pictures and ask the students to differentiate between the leaves of the flowering and non-flowering plants.
- The following plants are found in Pakistan. Identify these as flowering or non-flowering plants.
Sum up / Conclusion
- Tell the students plants can be classified into groups on the basis of the production of flowers. These two groups of plants are;
- Flowering plants and non-flowering plants
- Flowering plants produce flowers oranges, apples, wheat, rice, roses. Students will add other names. (Show pictures of the flowering plants)
- Non-flowering plants don`t produce flower e.g., ferns, conifers etc. (Show pictures of other non-flowering plants too)
- Explain more characteristics of flowering plants to the students.
- All the flowering plants produce seeds in their life cycles (recall from “The Life Cycle of Plants” learnt in class IV). Their seed is surrounded by the fruit (think of an apple).
- They usually have broad leaves. Explain characteristics of non-flowering plants to the students.
- All of them don`t produce seeds. Conifers are the non-flowering plants that produce seeds. Their seeds are not covered with fruit, but are produced in open cones (like pine cone).
- They usually have needle –like leaves. In many non-flowering plants e.g., in conifers, the leaves stay green throughout the year
- What are the characteristics of plants? Each student will tell one characteristic.
- The teacher will make the table on the writing board and fill it with the help of students
- Students may be asked to collect 5-7 pictures / real specimen of flowering and non-flowering plants and paste them in note book
