7.1 Herbs, Shrubs, and Trees

Plants are classified into herbs, shrubs, and trees. It is the thickness of the stem and origin of the branches that state their classification. The stems of herbs are green and frail. In most cases, these are small plants without many branches. Some of the examples include coriander, basil, oregano, thyme, mint, rosemary, parsley, etc. Herbs lack woody stems and thus are not strong like trees. The heights are also not much taller than shrubs or trees. Generally, herbs are not longer than a meter and also have a short life span.  They hardly live for a season or two. Herbs are also flowering plants and some of them also have medicinal values. Herbs are known for their flowering scent. Herbs have nutritional benefits and also provide flavour when used in cooking. One typical example is coriander leaves. 

Shrubs

Any medium-sized plant is called shrub. Compared with herbs they are much bigger in width, height, and breadth. They have skinny branches and start growing from the base. Some examples include lemon, rose, jasmine, aloe vera, blackberry, etc. they are taller than herbs and shorter than trees. The stems of most shrubs are hard and woody; however, they are not as thick as trees. They can live up to many years but cannot be compared to the lifespan of trees. 

Trees

Trees are much larger and taller than herbs and shrubs. They have stiff stems and their branches spread out after a certain height. They originate from a specific height above the ground. Some of the examples include neem, peepal, coconut, mango, Banayan, etc. A typical tree consists of a large main branch called the trunk. The other branch originates from the main branch. The trees provide good shade to the ground from where they grow. 

7.2 Stem 

The stem of the plant is the passageway through which water travels to different parts of the plant. The minerals from the water are also passed through the stem. They have very thin tubes through which minerals and water are passed to leaves and every tip of plants. The stem of the plant bears flowers, additional branches, fruits, leaves, and flowers. Considering the root as the source of minerals and water, it is the stem that supplies throughout the system. The transported minerals and water are converted to usable products for the process of photosynthesis. 

7.3 Leaf

The size, shape and colour of leaves depend on the type of plant. The part that connects the leaf with the stem is called petiole. The green part of the leaf is known as the lamina. If you notice you will find thin lines across the leaves, just like the main backbone and other bones spreading sideways. These are called the veins of the leaves. The main vein in the middle is known as the midrib, and the design of the veins is known as leaf venation. Some leaves have parallel veins that help in performing certain functions. 

7.4 Root

The root is one of the most vital parts. It is responsible for sipping valuable necessities for the plant. Among them, water and minerals are the most important. Roots perform valuable functions which are important for the growth of the plant. Roots play the anchor role for the plants and stand firmly on the ground. This specifically bolsters the upright position of the plant. Roots are storage houses for important nutrients and food required for growth. Roots are categorised into two types. These roots are fibrous roots and taproots. 

7.5 Flower   

Flowers are the adorning part of the plant. They are colourful and seed-bearing parts of the plant. They grow right at the end of a stem. The colours of the plants mainly come from the petals, which are the broader section of the flower. They together form the corolla of the flower. The leaf-like section of the flower is called sepal and it is responsible for enclosing the petals and providing protection to the flowers. It plays a crucial role in protection, especially when the flower is in the bud form. The stamen of the flower stays inside and can be seen when the flowers are removed.

FAQs (Frequently Asked Questions)

1. What is the function of leaves?

The primary function of leaves is to perform the process of photosynthesis. It is a crucial process for plants. The flat part of the leaves absorbs maximum sunlight and helps to cook the food (water minerals and other nutrients) required for the plants.

2. How to find out the type of root a plant has?

The type of root can be identified by the vein’s structure and the impression of the leaf on a sheet of paper. When a leaf has parallel venation, it is likely to have roots in fibrous form. On the other hand, if a leaf has reticulate venation, it is likely to have taproots.

3. What are the main functions of the roots according to Chapter 7 of Class 6 Science?

The root is a part of the plant present below the soil. The main functions of the root are:

  • It prevents the soil from being blown away by the wind or washed away by water and helps in holding the soil together.
  • It absorbs from the soil water and minerals which are needed to produce food by the leaves.
  • It also acts as an anchor of the plant as it firmly roots the plant to the ground, preventing the plant from being easily blown away by the wind.

 

4. How to answer difficult questions regarding Chapter 7 of Class 6 Science?

Students should have a strong grip on the concepts covered in the chapter. They should focus more on important topics from an exam point of view. To answer any kind of question, students should have a clear understanding of the concepts. Students are recommended to answer the questions at the end of the chapter to assess how well they have prepared for their exams. Use diagrams to explain theory wherever necessary.
