The NCERT Solutions for Nutrition in Plants provides students with a basic understanding of its concept and functionality. This is one of the most critical chapters in science. The Msvgo app explains Nutrition in Plants in detail, the nutrition process and the importance of nutrition in living organisms. It also goes over different types of nutrition in plants and animals.

Now, we will discuss What are the modes of nutrition in plants? How do Plants Get Nutrients? Remember that plants can produce their food, but humans and animals cannot. Students can get these answers through the Msvgo app by discussing the concepts and the various modes of nutrition. Nutrition is a vital aspect of a plant's existence since food offers nutrients such as carbohydrates, proteins, fats, vitamins, and minerals that help plant development, repair any damaged body parts and general health. Nutrients also offer the energy required for essential living functions.

 

Plant nutrition can be broadly classified as follows:

• Autotrophic mode of nutrition

• Heterotrophic mode of nutrition

 

Following on from the previous section's discussion of the modes of nutrition in plants, this section covers the Autotrophic Mode of Nutrition in depth. The NCERT Solutions for Class 7 Science defines the Autotrophic Mode of Nutrition and covers how plants produce food. 

 

In Chapter 12, students are asked to consider how plants make food. It is accomplished by photosynthesis, which is how plants produce food. The autotrophic nutrition mode allows organisms to create food from simpler substances found in their surroundings. Plants, for example, are autotrophs.

 

This process is one of the most significant parts of the Science curriculum. Photosynthesis is an exciting topic that the Msvgo app may easily understand. You might be amazed to learn that leaves are plants' food factories. Plants are the only species that can use sunlight, water, carbon dioxide, and minerals to make food. The leaves contain chlorophyll, a green substance that absorbs sunlight energy. This light energy is utilised in the preparation of food. As a result, this process is known as 'Photosynthesis.' 

 

The phases involved in photosynthesis are as follows:

• Using chlorophyll, a green pigment found in plant leaves captures sunlight energy.

• The light energy is subsequently turned into chemical energy used to produce food.

• The water in the leaves is then broken down into oxygen and hydrogen.

• The chemical energy is then utilised to transform carbon dioxide into glucose, subsequently used to produce food.

 

The NCERT Solutions for Class 7 Science emphasises that some plants do not produce food and are dependent on other living organisms because they lack the green pigment called chlorophyll. Such a mode of nutrition in plants is referred to as a heterotrophic mode of nutrition, and such plants are referred to as heterotrophic plants.

 

The following are the different heterotrophic modes of nutrition in plants:

• Parasitic 

• Insectivorous

• Saprophytic

• Symbiotic

Parasitic Nutrition

According to NCERT Solutions for Class 7, parasites are plants that rely on other living organisms for nutrition. This relationship does not benefit the plants on which parasites rely, such as Cuscuta.

Insectivorous Nutrition

According to NCERT Solutions for Class 7, Insectivorous plants have a specific trait or component for collecting insects. Pitcher plants, for example, contain nutrients from captured insects using unique digestive secretions.

Saprophytic Nutrition

Saprotrophs are plants that receive vital nutrients from dead plants and animals, according to NCERT Solutions for Class 7. For example, it has the same digestive fluids as insectivorous plants and uses them to acquire critical nutrients from mushrooms.

Symbiotic Nutrition

According to NCERT Solutions for Class 7, in such a nutrition mode, two plants work together to create nutrients in a symbiotic connection. This relationship benefits both plants involved in a symbiotic interaction.

 

1. What are the types of nutrition in plants?

Ans. Types of nutrition in plants are broadly classified as

• Autotrophic nutrition

• Heterotrophic nutrition

2. What is the importance of nutrition in plants?

Ans. Nutrition is an essential process without which plants' survival is impossible as it helps in the growth of plants, replenishment of damaged plant parts, and staying healthy.

3. What are the three types of nutrition?

Ans. The three types of nutrition in plants are as follows:

• Autotrophic 

• Heterotrophic 

• Symbiotic 

4. What is the definition of nutrition in animals and plants?

Ans. Nutrition in animals and plants is how these living organisms absorb nutrients from their surroundings, obtain food, and use it.

5. Why do animals and plants require food?

Ans. Animals and plants require nutrition for the following reasons:

• To maintain their health.

• For proper development

• Replenish any damaged body part

• Obtain the energy needed to complete the necessary tasks and work.

    6. Give a brief description of the Photosynthesis process by which food is synthesised in green plants.

Ans: Photosynthesis is how food is synthesised in green plants. In the presence of sunlight, chlorophyll in the cells of the leaves uses carbon dioxide and water to synthesise carbohydrates. 

This process releases oxygen, and the carbohydrates produced are stored as starch.

    7. Which of the following statements is/are true?

(i) All green plants can prepare their food.

(ii) The majority of animals are autotrophs.

(iii) Photosynthesis does not require carbon dioxide.

(iv) During photosynthesis, oxygen is released.

Choose the right answer from the following options:

(a) (i) and (iv) (b) (ii)only (c) (ii) and (iii) (d) (i) and (ii)

 

Ans: (a) (i) and (iv)

All green plants can prepare their own food.

During photosynthesis, oxygen is released

 

(a) Green plants are known as ____ because they produce their food.

(b) Plants synthesise food and store it as ____.

(c) The pigment ____ captures sunlight energy during photosynthesis.

(d) Plants absorb ____ and emit oxygen during photosynthesis.

 

Ans:

(a) Green plants are known as __autotrophs__ because they produce their food.

(b) Plants synthesise food and store it as __starch__.

(c) The pigment ___chlorophyll__ captures sunlight energy during photosynthesis.

(d) Plants absorb __carbon dioxide__ and emit oxygen during photosynthesis.

 

We studied how nutrition is an essential element for plants, different modes of nutrition in plants, photosynthesis, and other nutrition methods in The Msvgo app Chapter 1 of class 7 Science Nutrition in plants. 

 

The NCERT solutions in this section will assist students in understanding the concepts. To summarise, nutrition in plants is an essential and significant chapter of science. As a result, visual representations of topics are required. The MSVgo app is a video library that uses exploratory visualisations to help you understand topics. MSVgo enables you to understand the science behind concepts and phenomena through animations and videos. Check out the videos on the MSVgo app for a better understanding and clarification. As a result, using Msvgo App is beneficial in getting detailed information.
