CBSE Class 5 EVS Seeds And Seeds Worksheet Set 01

Comp. Identification.

I. Connect the plants to their native countries.
Plants given: Tomato, potato, peas, cabbage, mango, green chilli, coffee bean, bhindi, banana, spinach.
Native regions given: South America, Europe, Africa, India.
Answer:
- South America: Tomato, potato, green chilli
- Europe: Cabbage, peas
- Africa: Coffee bean, bhindi
- India: Mango, banana, spinach
In simple words: Different fruits and vegetables originally came to India from different parts of the world.

Exam Tip: Memorize the origin countries of common vegetables and fruits as asked in textbook mapping exercises.

II. Think and write:

1. Seeds kept in air tight containers do not sprout.
Answer: Seeds need oxygen from the air for respiration and growth. Airtight containers prevent air (oxygen) from entering, which stops the seeds from sprouting.
In simple words: Seeds need air to breathe and germinate.

Exam Tip: Remember the three essential conditions for seed germination: water, air, and suitable temperature.

2. Seeds kept in refrigerators do not sprout.
Answer: Refrigerators are very cold. Seeds require warmth (suitable temperature) to activate their enzymes and begin growing. The low temperature in a refrigerator prevents germination.
In simple words: It is too cold inside a refrigerator for seeds to grow.

Exam Tip: Low temperatures put seeds into a dormant (inactive) state.

III. Group them under suitable headings

List of fruits: mango, litchi, guava, banana, orange, grapes, gooseberry, papaya, pineapple, dates, watermelon, coconut, apple, tamarind, chilli.

Observation

Q.1. Given on the left is the picture of some chanas soaked in water in a bowl. On the right is an empty bowl. Draw how the bowl would look like after the chanas have been left to soak for 7-8 hours.
Answer: After soaking for 7-8 hours, chana seeds absorb water, swell up in size, and occupy more volume in the bowl. The water level in the bowl decreases as water enters the seeds.
In simple words: Soaked chanas swell up and become bigger because they absorb water.

Exam Tip: Mention that seeds swell and increase in volume upon soaking.

Q.2. Given below is a picture of a sprouted chana. One of the thread like structure coming out of the chana develops into root while the other develops into shoot (stem). Write in the spaces provided the name of the parts.
Answer:
- Top structure growing upwards: Shoot (Stem)
- Bottom structure growing downwards: Root
In simple words: The upper part grows into the shoot and the lower part grows into the root.

Q.3. Seeds grow into a new plant. Arrange them into a proper sequence by numbering.
Answer: The correct chronological sequence from seed to mature plant with flowers/fruit is:
1. Dry seed resting.
2. Seed absorbing water and swelling.
3. Seed sprouting with tiny root and shoot emerging.
4. Seedling growing small leaves and roots spreading in soil.
5. Young plant growing taller with more leaves.
6. Fully grown mature plant with branches and leaves.
In simple words: Seeds first swell, sprout roots and shoots, and then grow step-by-step into a full plant.

Exam Tip: Always follow the stages of germination: Seed \(\rightarrow\) Swelling \(\rightarrow\) Sprouting \(\rightarrow\) Seedling \(\rightarrow\) Mature plant.

Q.4. Observe the picture and name the part of the plant that grows into a new plant.
Answer:
- Bryophyllum: Leaf (Buds on leaf margin)
- Lily: Bulb
- Rose: Stem cutting
In simple words: Different plants reproduce through different parts like leaves, stems, or underground bulbs.

Exam Tip: Learn vegetative propagation examples clearly (Bryophyllum = leaf, Rose = stem).

Identification

Q.5. Do you know? Seeds are great travelers. How do the following seeds reach different places? Write (W) if they are carried by water, (A) if they are carried by animals, (B) if they are carried by air and (S) if they are thrown by splitting.
Answer:
- Lotus / water-based floating seeds: (W) Carried by water
- Cocklebur / spiky seeds with hooks: (A) Carried by animals
- Dandelion / hairy or winged seeds: (B) Carried by air
- Pea pod / bean pod bursting open: (S) Thrown by splitting (explosion)
In simple words: Seeds travel using wind, water, animals, or by bursting open.

Exam Tip: Connect seed features to their dispersal agent: hair/wings mean wind (air), hooks mean animals, spongy parts mean water, and pods mean splitting.
