Q5: Answer the following questions.


(i)  Give two examples for each:
(a) Living things
(b) Non-living things

(b) Non-living things: Two examples of non-living things are tables and chairs.

(ii) How does a plant breathe while it has no nose?
Ans:
Plants do not have noses like animals do. Instead, they breathe through tiny pores called stomata, which are mainly found on the surface of their leaves. Stomata open and close to allow the exchange of gases, such as carbon dioxide and oxygen, with the surrounding atmosphere. This process is called respiration in plants.

(iii) Name any five animals which lay eggs.
Ans: 
Five animals that lay eggs are snakes, crocodiles, hens (chickens), frogs, and ducks.

(iv) How do most plants reproduce?
Ans: 
Most plants reproduce through the formation of seeds. During the process of pollination, pollen from the male part of a flower (anther) is transferred to the female part (stigma) of the same or another flower. This fertilizes the ovule, leading to the formation of seeds. These seeds can then grow into new plants under suitable conditions.

FAQs on Living Things - 2 Class 4 Worksheet Science

1. What are the characteristics of living things?
Ans. Living things have certain characteristics that distinguish them from non-living things. These characteristics include the ability to grow, reproduce, respond to stimuli, obtain and use energy, and adapt to their environment.
2. How do living things obtain energy?
Ans. Living things obtain energy through various processes. Plants, for example, use photosynthesis to convert sunlight into chemical energy, while animals obtain energy by consuming plants or other animals. Some living things, such as bacteria, can obtain energy through other means, such as chemosynthesis.
3. How do living things reproduce?
Ans. Living things reproduce in different ways. Most animals reproduce sexually, where male and female individuals contribute genetic material to create offspring. Plants can reproduce sexually through the fusion of pollen and eggs, but they can also reproduce asexually through processes such as budding or vegetative propagation.
4. How do living things respond to stimuli?
Ans. Living things have the ability to respond to stimuli in their environment. This can be seen in various ways, such as plants bending towards sunlight, animals reacting to danger, or even single-celled organisms moving towards sources of food. These responses are often essential for survival and maintaining homeostasis.
5. How do living things adapt to their environment?
Ans. Living things have the ability to adapt to their environment through the process of natural selection. Individuals with traits that are advantageous for their survival and reproduction are more likely to pass on those traits to future generations. Over time, this can lead to adaptations in the population that increase their chances of survival in a particular environment.
