GSEB Class 6 Science Solutions Chapter 7 Getting to Know Plants

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 stamens 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.
Answer:
(a) Roots absorb water and minerals from the soil. Roots take in water and nutrients from the earth.
(b) Roots hold the plant upright. Roots keep the plant standing tall.
(c) Stem conducts water to the leaves. The stem moves water up to the leaves.
(d) The number of petals and stamens in a flower usually have no relation. The quantity of petals and stamens in a flower do not typically have a direct connection.
(e) If the sepals of a flower are joined together, its petals are not necessarily joined together. If a flower's sepals are connected, its petals don't always connect together.
(f) If the petals of a flower are joined together, then the pistil is not necessarily joined to the petal. If a flower's petals are linked, then the pistil is not always attached to the petal.
In simple words: Many plant parts have specific jobs. Roots take in water, stems move it, and leaves use sunlight. Sepals and petals protect a flower, but how they join can vary, and this often doesn't affect other parts like the pistil.

Exam Tip: Remember the specific functions of each plant part (roots, stem, leaves, sepals, petals, pistil) and how they relate. Pay attention to terms like 'reticulate venation' and 'fibrous roots' as these indicate key characteristics.

Question 2. Draw (a) a leaf, (b) a tap root and (c) a flower, you have studied for Table 7.3 of the textbook.
Answer: The question asks for botanical drawings of a leaf, tap root, and flower. These are detailed illustrations that cannot be accurately represented using the provided simple SVG templates for geometric figures like Venn diagrams. Therefore, the visual diagrams are omitted from this text-based output.

Exam Tip: When asked to draw, always label the key parts of the diagram accurately to score full marks.

Question 3. Can you find a plant in your house or in your neighborhood that has a long but a weak stem? Write its name. In which category would you place it?
Answer: Yes, we find a money plant in our house. It is a climber. Yes, we have a money plant at home. It is a plant that climbs.
In simple words: A money plant is common in homes, and it has a long, weak stem that makes it a climber.

Exam Tip: Understand the different categories of plants based on their stem characteristics (e.g., creepers, climbers, herbs, shrubs, trees).

Question 4. What is the function of a stem in a plant?
Answer: A stem performs the following functions:
• The stem and its branches hold leaves to get maximum sunlight. The stem and its parts help leaves reach for much sunlight.
• It transports water from roots to different parts of the plant. It carries water from the roots to various sections of the plant.
• It transports food from leaves to different parts of the plant. It moves food from the leaves to other plant areas.
• It bears leaves, flowers, and fruits. It holds leaves, blossoms, and fruits.
In simple words: The stem acts like a central support, holding leaves up for sun and moving water and food throughout the entire plant. It also produces leaves, flowers, and fruits.

Exam Tip: When asked about functions, list them clearly using bullet points and provide a concise explanation for each point.

Question 5. Which of the following leaves have reticulate venation? Wheat, tulsi, maize, grass, coriander (dhania), china rose.
Answer: Tulsi, china rose. Tulsi and china rose leaves show a net-like vein pattern.
In simple words: Leaves like tulsi and china rose have veins that spread out like a net.

Exam Tip: Distinguish between reticulate (net-like) and parallel venation by observing common plant leaves around you.

Question 6. If a plant has fibrous roots, what type of venation are its leaves likely to have?
Answer: Parallel venation. Its leaves will likely display parallel veins.
In simple words: Plants with fibrous roots typically have leaves where the veins run side-by-side.

Exam Tip: Remember the general correlation: fibrous roots usually mean parallel venation, and taproots usually mean reticulate venation.

Question 7. If a plant has leaves with reticulate venation, what kind of roots will it have?
Answer: Taproot. It will possess a single, main taproot.
In simple words: A plant with net-like veins in its leaves will most likely have one main root called a taproot.

Exam Tip: This is the inverse of the previous question; ensure you understand the relationship in both directions.

Question 8. Is it possible for you to find out whether a plant has taproot or fibrous roots by looking at the impression on its leaf on a sheet of paper?
Answer: Yes, by taking the impression of the leaf. Put the leaf under a white sheet and gently rub the pencil on it with tip sideways. We will get an impression of the leaf with lines on it. If the leaf has parallel venation then the plant has the fibrous root and if the leaf has reticulate venation then the plant has a taproot. Yes, it is possible by making an impression of the leaf. Place the leaf beneath a plain sheet of paper and gently rub a pencil with its side over it. You will see the leaf's pattern with lines. If the leaf shows parallel veins, the plant has a fibrous root system. If the leaf has net-like veins, the plant then has a taproot.
In simple words: You can see a leaf's vein pattern by rubbing a pencil over it on paper. If the veins are parallel, the plant has fibrous roots. If they're net-like, it has a taproot.

Exam Tip: This method is a practical way to identify root types indirectly. Practice making leaf impressions to understand the venation patterns.

Question 9. What are the parts of a flower?
Answer: The names of various parts of a flower from outside to inside are: The different parts of a flower, listed from the outer layer to the inner, include:
1. Sepals
2. Petals
3. Stamens
4. Pistil
In simple words: From the outside to the inside, a flower has sepals, then petals, then stamens, and finally the pistil.

Exam Tip: Learn the parts of a flower in order, as this helps in understanding their functions during pollination and reproduction.

Question 10. From the following plants, which of them have flowers? Grass, maize, wheat, chili, tomato, tulsi, peepal, shisham, banyan, mango, Jamun, guava, pomegranate, papaya, banana, lemon, sugarcane, potato, groundnut.
Answer:

Exam Tip: Understand that even plants like grass and wheat, which might not have showy flowers, do indeed flower as part of their reproductive cycle.

Question 11. Name the part of the plant which produces food. Name the process.
Answer: Leaves produce food for the plant. This process is called photosynthesis. Leaves create food for the plant. This important process is known as photosynthesis.
In simple words: Leaves make the food for a plant through a process called photosynthesis.

Exam Tip: Remember that leaves are the primary food factories of plants and photosynthesis is the vital process they use.

Question 12. In which part of a flower you are likely to find the ovary?
Answer: We find an ovary in the pistil. It is the lowermost part of the pistil. You can locate an ovary within the pistil. It is the bottommost section of the pistil.
In simple words: The ovary is found inside the pistil, which is at the very bottom part of a flower's female reproductive structure.

Exam Tip: The pistil is the female reproductive part of a flower, and the ovary is its basal, swollen part containing ovules.

Question 13. Name two plants in which one has joined sepals and the other has separate sepals.
Answer:
Flowers with joined sepals:
• Datura
• Bottle gourd
Flowers with separate sepals:
• Rose
• Mustard
In simple words: Datura and bottle gourd have sepals that are connected, while rose and mustard flowers have sepals that are not joined.

Exam Tip: Observe different flowers carefully to distinguish between joined and separate sepals, as this is a key botanical characteristic.
