Chapter summary

Chapter 7, "Getting to Know Plants," focuses on identifying and understanding the different parts of a plant and their specific functions. The NCERT Solutions cover exercises related to stems, leaves, roots, and flowers, explaining concepts like water absorption, conduction, venation patterns (reticulate and parallel), and root types (taproot and fibrous root). It emphasizes the relationship between leaf venation and root type, and the roles of various plant structures in the plant's survival and growth.

Learning outcomes

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:

(a) Roots absorb water and minerals from the soil. The stem's primary role is support and transport, not absorption from the soil.

(b) Stem holds the plant upright. The stem provides structural support, allowing the plant to stand tall and hold its leaves, flowers, and fruits.

(c) Stem conducts water to the leaves. After absorption by the roots, water travels up through the stem to reach the leaves.

(d) The number of petals and sepals in a flower is not always equal. The number can vary significantly between different types of flowers.

(e) If the sepals of a flower are joined together, its petals are separate and not joined together. While sepals can be fused, this doesn't automatically mean the petals are also fused.

(f) If the petals of a flower are joined together, then the pistil is not necessarily joined to the petal. The pistil's connection to petals depends on the specific flower structure and is not a direct consequence of fused petals alone.

Question 2

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

Students should draw the following based on their observations and studies:

(a) A Leaf: Draw a typical leaf showing its blade and petiole. If possible, indicate the venation pattern (reticulate or parallel).

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

(c) A Flower: Draw a simple flower, showing its main parts like sepals, petals, stamens, and pistil. Ensure the drawing is clear and labelled if required by the table.

Question 3

Can you find a plant in your house or in your neighborhood, which has a long but a weak stem? Write its name. In which category would you classify it?
Solution:

Yes, a plant like the Money Plant often has a long but weak stem. Such plants are typically classified as climbers because they need support, such as walls, sticks, or other plants, to grow upwards.

Question 4

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

The stem performs several crucial functions for a plant:

  • Support: It holds the branches, leaves, flowers, and fruits, displaying them towards sunlight and facilitating pollination and seed dispersal.
  • Transport of Water and Minerals: The stem contains tissues (xylem) that transport water and dissolved minerals absorbed by the roots upwards to the leaves and other aerial parts of the plant.
  • Transport of Food: It also contains tissues (phloem) that transport the food (sugars) prepared during photosynthesis in the leaves to all other 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 have reticulate venation among the given options are: Tulsi, Coriander (Dhania), and China rose. Reticulate venation means the veins form a network or web-like pattern within the leaf blade.

Question 6

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

If a plant has a fibrous root system, its leaves are likely to have parallel venation. In parallel venation, 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 have?
Solution:

If a plant has leaves with reticulate venation, it will typically have a taproot system. The main taproot grows deep into the soil, with smaller lateral roots branching off.

Question 8

Is it possible for you to recognize the type of leaves by looking at their roots? How?
Solution:

Yes, it is possible to infer the type of leaf venation by observing the plant's root system, and vice versa. This is because there is a general correlation:

  • Plants with leaves exhibiting reticulate venation (veins forming a network) usually possess a taproot system.
  • Plants with leaves showing parallel venation (veins running parallel) typically have a fibrous root system.

By identifying whether the plant has a taproot or fibrous roots, one can make an educated guess about the venation pattern of its leaves, and vice versa.

Common mistakes

  • Confusing the functions of stems and roots (e.g., stem absorbing water).
  • Incorrectly associating specific venation patterns with incorrect root types.
  • Misidentifying the roles of petals and sepals in a flower.
  • Assuming a fixed number of petals and sepals in all flowers.

Revision tips

  • Review the diagrams of leaves, taproots, and flowers to reinforce visual identification.
  • Create a table summarizing the functions of stems, leaves, and roots.
  • Focus on the relationship between leaf venation and root type, as it's a key concept.
  • Practice correcting the given statements to ensure a clear understanding of plant part functions.

Practice MCQs

Q2. What type of venation is typically found in plants with fibrous roots, like grass?

Q3. Which of the following plants has reticulate venation in its leaves?

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

Q5. If a flower's sepals are joined together, what can be said about its petals?

Frequently asked questions

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

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

How can I identify reticulate venation in leaves?

Reticulate venation is characterized by veins forming a network or a web-like pattern throughout the leaf blade. Examples include Tulsi, Coriander, and China rose.

What is the difference between taproot and fibrous root systems?

A taproot is a single, thick main root from which smaller roots grow. Fibrous roots consist of a cluster of thin, thread-like roots arising from the base of the stem.

Is there a relationship between the type of leaf venation and the root system?

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

How do these NCERT solutions help with exam preparation?

These solutions provide clear, rewritten answers to all chapter exercises, helping students understand concepts, correct common misconceptions, and practice identifying plant parts and their functions accurately.

Which plants are mentioned as examples of climbers?

Money Plant is mentioned as an example of a plant with a long but weak stem that can be classified as a climber.
