Living Creatures: Exploring their Characteristics Chapter 10
Living Creatures: Exploring their Characteristics
1. Similarities and Differences
Similarities:
- Both grow, develop, and reproduce.
- Plants grow from seeds.
- Animals grow from eggs or birth.
- Animals can move, whereas plants cannot.
2. Study the Data
Condition | Example |
---|---|
Grows in water | Lotus |
Grows in dry soil | Cactus |
Answer: The proper answer will be uploaded soon. Without the table, here's a general example: Some conditions may not suit any plant or animal, so sometimes examples aren't possible.
3. Proper Storage of Grains
We must store grains in a dry and cool place to prevent them from germinating. No water, warmth, or air should reach stored grains in order to stop them from germinating.
4. Advantage of Tadpole's Tail
The tail helps tadpoles swim easily in water and escape from enemies. It also helps them move efficiently to find food.
5. Living or Non-Living?
Charan is correct. A wooden log is non-living because it doesn’t grow, breathe, or move. Although it was once part of a living tree, the log itself is non-living.
6. Mosquito vs. Frog Life Cycle
Similarities | Differences |
---|---|
Both lay eggs in water. Both develop through stages before becoming adults. Both exhibit major body changes during their growth. |
Mosquito: Egg, Larva, Pupa, and Adult. Frog: Egg, Tadpole, and Adult. Tadpoles use tails to swim, while mosquito larvae wiggle in the water. Frogs develop lungs and legs; mosquitoes grow wings. |
7. Plant Growth Prediction
After one week, the shoot will grow upwards while the root grows downwards. Shoots grow towards sunlight, and roots grow towards moisture and gravity.
8. Experiment: Do Plants Need Sunlight?
Tara and Vijay aim to find out if plants need sunlight to grow. If the plant kept in darkness doesn't grow well, they will conclude that sunlight is important.
9. Experiment: Temperature & Seed Germination
Place seeds in two bowls—one kept in a warm place and the other in a cold place. Keep water and soil consistent, and after a few days, compare the number of seeds that sprout in each.
