Nutrition in Plants involves the process by which plants absorb and utilize essential nutrients from the soil and atmosphere. Key to this is photosynthesis, where plants convert sunlight, carbon dioxide, and water into glucose and oxygen. Essential nutrients, including macronutrients like nitrogen, phosphorus, and potassium, and micronutrients like iron and zinc, support various growth and metabolic functions. Understanding plant nutrition is crucial for ensuring healthy plant development and agricultural productivity.
Answer. The components of food that are important for our body, are called nutrients.
Our nutrients are Carbohydrates, Protein, Fat, Vitamin and minerals.
Who can synthesis their own food and who can't?
Answer. Plants can make their own food and animals can’t.
What is nutrition?
Answer. The mode of taking food by organisms consume and utilize that food for growth, energy, and maintenance of bodily functions is called Nutrition.
What are the functions of nutrients?
Answer. The nutrients help living organisms build their bodies, grow, repair damaged parts of their bodies and provide energy to carry out life processes.
What is Autotrophic nutrition?
Answer. The mode of nutrition in which organisms make their own food from simple substances is called autotrophic nutrition.
What are Autotrophs?
Answer. The organisms which can make their own food from simple substances are called autotrophs. Plants are autotrophs.
What is heterotrophic nutrition?
Answer. The mode of nutrition in which organisms can not make their own food and take food prepared by plants, is called heterotrophic nutrition.
What are Heterotrophs?
Answer. The organisms which cannot make their own food and take food prepared by plants, are called heterotrophs.
Which part of plant is known as food factory?
Answer. Green leaves.
What are Stomata?
Answer. Plants leaves have tiny pores on the surface of the leaves these pores are called stomata.
What is the function of Stomata?
Answer. Stomata exchange gases (like oxygen and Carbon-di-oxide) by closing and opening the pores in the leaves.
What are cells?
Answer. The living body is made up of tiny basic and structural units of life called cells.
What is cell membrane?
Answer. All the living cell is
enclosed by a thin outer boundary or a layer, called the cell membrane or
plasma membrane.
What is Nucleus?
Answer. Cells have distinct spherical structure at the centre of it, is called nucleus.
What is cytoplasm?
Answer. The nucleus is surrounded by a jelly-like substance called cytoplasm.
Why leaves of plants are green?
Answer. Plants leaves have green pigment chlorophyll present in them, this is why the leaves of plants are green.
What is the ultimate source of all living organisms?
Answer. Sun
What is Photosynthesis?
Answer. The process by which green leaves prepare their own food by using carbon di-oxide and water in the presence of sunlight and chlorophyll is called photosynthesis. (learn more)
What is transpiration?
Answer. The process of release of excess water by the plants into air through stomata, is called transpiration.
Write the equation of Photosynthesis?
Which element is present in Protein?
Answer. Nitrogen.
Name a plant which does not have chlorophyll.
Answer. Cuscuta
What is host?
Answer. A plant or animal on which another plant or animal lives and feeds is called host.
What is parasite?
Answer. An organism that lives on or in a host organism and gets its food from the host is called parasite.
What is insectivorous?
Answer. The plants which fulfill their protein requirement by eating insects are called insectivorous plants. For example: Pitcher
plant, Venus Flytrap, Bladderwort, Drosera, Rafflesia
What are parasite plants?
Answer. The plants which derive some or all of the nutrients they need from another plant(host), are called parasites.
Examples of parasites are Cuscuta, Mistletoe etc.

What is saprotrophic nutrition?
Answer. The mode of nutrition in which organisms take nutrients from dead and decaying matter is called saprotrophic nutrition.
What are saprotrophs?
Answer. The organisms which take nutrients from dead and decaying matter is called saprotrophs.
What are fungi?
Answer. The heterotrophic organisms with no chlorophyll that obtains nutrients by absorption and reproduces by spores are called fungi. Example; Mushroom, Agaricus, Cordyceps etc
What do you mean by symbiosis?
Answer. A relationship in which different organisms live together and mutually exchange shelter and nutrients, is called symbiosis.
What are leguminous plants?
Answer. The plants belong to legume family are called leguminous plants. For examples: Beans, Peas, Nuts etc.
These plants are notable due their ability to fix atmospheric nitrogen.
Name two nitrogen fixing bacteria.
Answer. Azotobacter and Rhizobium,
