Lesson 5 - Life Processes of Animals and Plants

1. Fill in the blanks with correct words.

Answer 👉 

a. Animals get energy from food.

b. Plants inhale oxygen gas in respiration.

c. Plants take in carbon dioxide gas in photosynthesis.

d. Animals and plants help to maintain balance between oxygen and carbon dioxide gas in atmosphere.

2. Make corrections if the following statements are false.

Answer 👉 

a. False. Plants need water, air, and nutrients from the soil for their growth.

b. False. Many animals depend on plants for their living, either directly as herbivores or indirectly as carnivores that eat other animals that have fed on plants.

c. False. Not all plants prepare their food by themselves. Some parasitic plants obtain nutrients from other plants, while some non-green plants are unable to produce their own food and rely on other sources of nutrition.

d. False. Plants absorb water through their roots and release water vapor through tiny pores in their leaves in a process called transpiration.

3. Write short answers.

a. How do plants get carbondioxide gas in preparing their food?

Answer 👉 Plants get carbon dioxide gas for preparing their food through tiny pores on their leaves called stomata. The carbon dioxide gas present in the air enters the plant through these stomata.

b. What elements are required for plants to prepare food? Where do they get them from?

Answer 👉 The elements required for plants to prepare food are carbon, hydrogen, and oxygen. Plants get carbon and oxygen from carbon dioxide gas present in the air, and hydrogen from water absorbed by their roots from the soil.

c. Write any four life processes of living things and explain them.

Answer 👉 

  1. Respiration: It is the process of converting food into energy in living cells. In this process, oxygen is taken in and carbon dioxide is released.
  2. Nutrition: It is the process of taking in and utilizing food by living organisms to maintain their life and growth.
  3. Excretion: It is the process of removing waste products from the body of living organisms. These waste products are harmful and can affect the functioning of the body if not removed.
  4. Reproduction: It is the process of producing offspring. It ensures the continuity of a species. There are two types of reproduction: sexual and asexual.
