Chapter summary

Chapter 7, 'Getting to Know Plants,' focuses on identifying and understanding the functions of different plant parts. The NCERT Solutions cover exercises on distinguishing between stems and roots, the types of leaf venation (reticulate and parallel), and their correlation with root types (taproot and fibrous root). It also touches upon the characteristics of flowers and plant classification based on stem strength.

Questions and Solutions

Question 1

Correct the following statements and rewrite them in your notebook:

(a) Stem absorbs water and minerals from the soil.

(b) Leaves hold the plant upright.

(c) Roots conduct water to the leaves.

(d) The number of petals and sepals in a flower is always equal.

(e) If the sepals of a flower are joined together, its petals are also joined together.

(f) If the petals of a flower are joined together, then the pistil is joined to the petal.

Solution:

Here are the corrected statements:

  1. (a) Roots absorb water and minerals from the soil.
  2. (b) Stems hold the plant upright.
  3. (c) Stems conduct water to the leaves.
  4. (d) The number of petals and sepals in a flower is not always equal.
  5. (e) If the sepals of a flower are joined together, its petals are separate and not joined together.
  6. (f) If the petals of a flower are joined together, then the pistil is not necessarily joined to the petal.

Question 2

Draw (a) a leaf, (b) a taproot and (c) a flower, you have studied for Table 7.3.
Solution:

Students are expected to draw these structures based on their observations and the information provided in the chapter. Here are descriptions of what each drawing should represent:

(a) A Leaf: Should show the leaf blade (lamina), the midrib, and veins. The venation pattern (reticulate or parallel) can be depicted.

(b) A Taproot: Should illustrate a main, thick root growing vertically downwards, with smaller lateral roots branching off from it.

(c) A Flower: Should include the main parts like sepals (often green, leaf-like structures at the base), petals (often colorful), stamens (male reproductive parts), and pistil/carpel (female reproductive part in the center).

Question 3

What is the name of a plant in your house or neighborhood that has a long but weak stem? In which category would you classify it?
Solution:

A common example of a plant with a long but weak stem is the Money Plant. Such plants are classified as climbers because they need support from other structures to grow upright.

Question 4

What is the function of a stem in a plant?
Solution:

The stem performs several vital functions for a plant:

  • Support: It holds the branches, leaves, flowers, and fruits, keeping them in a position to receive sunlight and air.
  • Conduction of Water and Minerals: The stem transports water and dissolved minerals absorbed by the roots upwards to the leaves and other aerial parts of the plant.
  • Transport of Food: It also transports the food (sugars) prepared during photosynthesis in the leaves to various parts of the plant where it is needed for growth or storage.

Question 5

Which of the following leaves have reticulate venation? Wheat, tulsi, maize, grass, coriander (dhania), China rose
Solution:

The leaves that exhibit reticulate venation among the given options are: Tulsi, Coriander (Dhania), and China rose. In these plants, the veins form a network-like pattern on the leaf blade.

Question 6

If a plant has a fibrous root system, what type of venation do its leaves likely have?
Solution:

Plants that possess a fibrous root system typically have leaves with parallel venation. In this pattern, the veins run parallel to each other from the base to the tip of the leaf blade.

Question 7

If a plant has leaves with reticulate venation, what kind of roots will it likely have?
Solution:

Plants whose leaves display reticulate venation are generally characterized by having a taproot system. A taproot is a single, prominent main root from which smaller lateral roots grow.

Question 8

Is it possible for you to recognize the type of leaves without seeing them? How?
Solution:

Yes, it is possible to infer the type of leaf venation without directly seeing the leaves by examining the plant's root system. Plants with leaves that have reticulate venation typically possess taproots. Conversely, plants with leaves exhibiting parallel venation usually have fibrous roots. Therefore, identifying the root type can help predict the leaf venation pattern.

Common mistakes

  • Confusing the functions of stems and roots, especially regarding water absorption and conduction.
  • Incorrectly associating specific leaf venation types with the wrong root systems.
  • Misidentifying the roles of petals and sepals in a flower.
  • Assuming a fixed relationship between the number of petals and sepals.

Revision tips

  • Review the corrected statements in Exercise 1 to reinforce basic plant part functions.
  • Practice drawing leaf, root, and flower diagrams as suggested in Exercise 2.
  • Create a table summarizing the relationship between leaf venation and root type (Exercises 5, 6, 7, 8).
  • Focus on understanding the transport functions of stems (Exercise 4) for exam preparation.

Practice MCQs

Q1. Which part of the plant primarily absorbs water and minerals from the soil?

Q2. The venation pattern where veins form a network is called:

Q3. Plants with fibrous roots typically have leaves with:

Q4. What is the main function of the stem in supporting the plant?

Q5. Which of the following plants has reticulate venation?

Frequently asked questions

What are the main functions of a plant's stem?

The stem supports branches, leaves, flowers, and fruits, holding them upright. It also transports water and minerals from the roots to other parts and carries prepared food from the leaves to the rest of the plant.

How can I distinguish between reticulate and parallel venation in leaves?

In reticulate venation, the veins form a network or web-like pattern on the leaf. In parallel venation, the veins run parallel to each other along the length of the leaf.

What is the relationship between leaf venation and the type of root system?

Plants with leaves having reticulate venation typically have taproots, while plants with leaves showing parallel venation usually have fibrous roots.

Which plants are mentioned as having reticulate venation in the NCERT solutions?

The NCERT solutions mention Tulsi, Coriander (Dhania), and China rose as examples of plants with reticulate venation.

How do these NCERT solutions help in preparing for exams?

These solutions provide corrected statements, clear explanations of plant functions, and highlight the relationship between different plant parts like leaves and roots, aiding in a better understanding and revision for exams.
