(viii) Eyes are sensitive to _____ and ears are sensitive to _____.
Ans: Eyes are sensitive to light and ears are sensitive to Sound.

Q4: True or False.


(i) Non-living things can grow and reproduce.
Ans: False
Growth and reproduction are characteristics of living things, not non-living things.

(ii) Living things can respond to their environment.
Ans: True
Living organisms can sense and react to changes in their environment to help them survive.

(iv) Living things can excrete waste.
Ans: True
Excreting waste is a part of the life processes that help maintain the internal environment of living organisms.

(v) Living things do not need energy to carry out their life processes.
Ans: False
Energy is required for growth, reproduction, and other life processes.

Q5: Short Answer Questions.


(i) What are the main characteristics that all living things share?
Ans: The main characteristics that all living things share are:

  • They are made up of cells.
  • They can grow and develop.
  • They need energy and nutrients to survive.
  • They can reproduce and produce offspring.
  • They respond to changes in their environment.

(ii) Why do living things need energy?
Ans: Living things need energy to carry out life processes such as growth, development, reproduction, and maintaining their internal environment (homeostasis).

(iii) How do living things get rid of waste?
Ans: Living things get rid of waste through excretion. This process helps them remove unwanted substances from their bodies, such as carbon dioxide, urea, and other waste products.

(iv) What is the importance of reproduction for living things?
Ans: Reproduction is important for living things because it allows them to create offspring and ensure the survival of their species. It also helps in maintaining a balance in the ecosystem and passing on genetic traits to the next generation.

(v) Describe the process of respiration in living things.
Ans: Respiration is the process by which living things obtain energy from the food they consume. During respiration, glucose (a sugar molecul(e) is broken down with the help of oxygen, producing carbon dioxide, water, and energy. This energy is then utilized by the cells to carry out various life processes.

Q6: Answer the following questions.


(i) Animals move from place to place whereas plants remain fixed at one point. What is the need for the animals to move about?
Ans: Plants make food by themselves, Plants get everything (soil, air, water, light, etc.) in the same place. So they don’t need to move. Animals depend on others for food and they have to move in search of food.

(ii) Animals are dependent on plants directly or indirectly. What do you understand by this statement?
Ans: Animals are heterotrophs means depend on plants for food such as flowers, fruits, vegetables, grains, etc. which are produced by plants through photosynthesis.

(iii) A human baby grows with time. A snowball grows in size as it rolls. What is the difference in the two growths?
Ans: The growth of a human baby is natural whereas the growth of a snowball is not natural.

(iv) A green plant takes in oxygen and gives out carbon dioxide. It also takes in carbon dioxide and gives out oxygen. How does this happen?
Ans: A green plant takes in oxygen and gives out carbon dioxide through its Stomata. This process is called transpiration. When plants take in carbon dioxide and give out oxygen, is called photosynthesis.

(v) Which are the other stimuli, the stem might respond to?
Ans: A money plant or cucumber plant starts climbing the moment it gets support. These plants respond to touch.

FAQs on Living Things - 1 Class 6 Worksheet Science

1. What are living things?
Ans. Living things are organisms that have the ability to grow, reproduce, respond to stimuli, and maintain homeostasis. They are made up of cells and exhibit various characteristics such as metabolism and evolution.
2. How do living things grow?
Ans. Living things grow through a process called cell division. During cell division, cells multiply and increase in number, leading to growth in size. This process is regulated by genetic information within the cells.
3. How do living things reproduce?
Ans. Living things reproduce through two main methods: sexual reproduction and asexual reproduction. Sexual reproduction involves the fusion of male and female reproductive cells, resulting in offspring with genetic variation. Asexual reproduction, on the other hand, involves the production of offspring without the involvement of gametes, leading to genetically identical offspring.
4. What is homeostasis in living things?
Ans. Homeostasis is the ability of living things to maintain internal stability despite changes in the external environment. It involves various physiological processes that regulate body temperature, pH levels, and other internal conditions within a narrow range suitable for life.
5. How do living things respond to stimuli?
Ans. Living things respond to stimuli through a process called irritability or responsiveness. They have specialized structures, such as sensory organs and nervous systems, that allow them to detect and respond to changes in their environment. This response can be in the form of movement, growth, or physiological changes.
