17 How plants obtain other
components of food? *
1 point
Plants obtain other nutrients from
the animals
Plants absorb other nutrients
directly from the soil.
O
Plants utilises carbohydrates to
synthesis other nutrients.
Plants depend on larger plants for
the synthesis of other nutrients.
Answers
Answer:
Synthesis of plant food other than carbohydrates
You have just learnt that plants synthesise carbohydrates through the process of photosynthesis. The carbohydrates are made of carbon , hydrogen and oxygen. These are used to synthesise other components of food such as proteins and fats.

How Nutrients are Replenished in the Soil
Processes. Plants take up essential elements from the soil through their roots and from the air (mainly consisting of nitrogen and oxygen) through their leaves. Nutrient uptake in the soil is achieved by cation exchange, wherein root hairs pump hydrogen ions (H+) into the soil through proton pumps.
The nutrients enable living organisms to build their bodies, to grow, to repair damaged parts of their bodies and provide the energy to carry out life processes. Nutrition is the mode of taking food by an organism and its utilisation by the body. The mode of nutrition in which organisms make food themselves from simple substances is called autotrophic (auto = self; trophos = nourishment) nutrition. Therefore, plants are called autotrophs. Animals and most other organisms take in ready made food prepared by the plants. They are called heterotrophs(heteros = other)

Nutrition in Plants
In Class VI you learnt that food is essential for all living organisms. You also learnt that carbohydrates,proteins, fats, vitamins and minerals are components of food. These components of food are necessary for our body and are called nutrients.
All living organisms require food. Plants can make their food themselves but animals including humans cannot. They get it from plants or animals that eat plants. Thus, humans and animals are directly or indirectly dependent on plants.
Mode of Nutrition in Plants
Plants are the only organisms that can prepare food for themselves by using water, carbon dioxide and minerals. The raw materials are present in their surroundings.

Now we may ask where the food factories of plants are located: whether food is made in all parts of a plant or only in certain parts? How do plants obtain the raw materials from the surroundings? How do they transport them to the food factories of the plants?
Photosynthesis Food Making Process in Plant
Leaves are the food factories of plants. The synthesis of food in plants occurs in leaves. Therefore, all the raw materials must reach there. Water and minerals present in the soil are absorbed by the roots and transported to the leaves. Carbon dioxide from air is taken in through the tiny pores present on the surface of the leaves. These pores
Answer:
plants absorb other nutrients directly from the soil
