- There are certain organisms that lives together and provides food and shelter to each other. This kind of nutrition is known as symbiotic relationship.
- This kind of relationship is very important for plants because there are certain microorganisms like fungi that lives in the rootsof trees and absorb the nutrients from The fungi in turn help the plants to absorb water and nutrientsfrom the soil required for the proper growth of plants.
- An example is lichens where a symbiotic relation exists between the alga and fungus.

The epidermis is a single layer of cells that covers the leaves, flowers, roots and stems of plants. It forms a boundary between the plant and the external environment. The epidermis serves several functions: it protects against water loss, regulates gas exchange, secretes metabolic compounds, and (especially in roots) absorbs water and mineral nutrients.

Auto means self and trophos means nourishment. Plants are called autotrophs because they make their food themselves. The making of food for themselves is called the Autotrophic nutrition. Autotrophic nutrition is found in green plants, and in some bacteria.

Nutrition is the study of nutrients in food, how the body uses them, and the relationship between diet, health, and disease. Nutrients provide nourishment. Proteins, carbohydrates, fat, vitamins, minerals, fiber, and water are all nutrients.

Photosynthesis reaction involves two reactants, carbon dioxide, and water. These two reactants yield two products, namely, oxygen and glucose. Hence, the photosynthesis reaction is considered to be an endothermic reaction. Following is the photosynthesis formula:
6CO2 + 6H2O —> C6H12O6 + 6O2

Because animals don't have chloroplasts in their cells like plants do. Plants use these things to make food and energy through a process called photosynthesis. If animals would have the ability to capture sunlight and produce energy for themselves there would be no need for plants and the carbon cycle would not exist.

The process of utilization of food by a living organism to obtain energy is called nutrition.
Auto means self and trophos means nourishment. Plants are called autotrophs because they make their food themselves. The making of food for themselves is called the Autotrophic nutrition. Autotrophic nutrition is found in green plants, and in some bacteria.
The word Heterotrophic is the combination of two words i.e. Hetero + Trophos. Hetero means ‘others’ and ‘trophos’ means nourishment. If organisms depend on others for their food, such a mode of nutrition is called Hetetrophic Nutrition.
The process of making of food by green plants in the presence of sunlight and chlorophyll is known as photosynthesis. Photosynthesis is the combination of two words- Photo + Synthesis. ‘Photo’ means light and ‘Synthesis’ means to make.

- Amoeba is a microscopic single-celled organism found in pond water which has a cell membrane, a round, dense nucleus and many bubble like vacuoles.
- The shape of amoeba is variable.
- It has tiny finger like projections called pseudopodia or false feet for movement and capture of food.
- It eats tiny organisms by spreading out its pseudopodia around its food particle and then engulfing it.
- The food gets trapped inside food vacuole, into which digestive juices are secreted and convert them into simpler substances.
- The digested food is then absorbed which is required for growth, maintenance and multiplication.
- The undigested food is expelled out by vacuole.

On the basis of physical state, matter is classified into three categories, such as solid, liquid and gas.
Matter basically exists in three physical states and these states are used to classify them in the physical form.
Matter is distinguished into solid, liquid or gas by the arrangement of the atoms in the mater.

A saprophyte secretes digestive juices on the dead and decaying matter to convert the solid substances into liquid. The saprophyte then absorbs the nutrients from this liquid.

Plants lose a lot of water through transpiration, hence this water has to be continuously replaced. The cells of the plant will shrink if there is water shortage.
Water is not only needed for photosynthesis, but also for transportation and maintenance of turgid state of cells. Plants also need water for obtaining minerals from soil.

Animals cannot make their food themselves. They depend for food upon plants. Therefore, nutrition in animals is called Hetetrophic Nutrition. Animals are known as Heterotrophs.

Meat-eating, or carnivorous, plants can trap and digest insects and other small animals. They do this to obtain the vital nitrogen that they need to grow. Carnivorous plants live in bogs, where nitrates are in short supply, so they need to obtain their nitrogen by digesting prey instead.
