VR Tour For Std. 7 Ch. 1: Nutrition in Plants

What's Included in Virtual tour of this chapter

Photosynthesis is a process in which plants use water and carbon dioxide in the presence of sunlight to synthesize glucose and release oxygen. Plants synthesize their own food by photosynthesis. So, they are called autotrophs. During photosynthesis, oxygen is released as the life-sustaining gaseous component of the atmosphere while glucose or food is transported to all parts of the plant and used for growth. Here plants synthesize their own food through photosynthesis. So they are called autotrophs and the mode of nutrition is called autotrophic nutrition.

Virtual tour 1: A deep Photosynthesis process

Green plants can make their own food by the photosynthesis process. Plant roots absorb water and send it to the leaves by xylem. A leaf absorbs carbon dioxide from the environment through the stomata. Both water and carbon dioxide are finally absorbed by the chloroplast. In the presence of sunlight, they synthesize glucose and release oxygen. The oxygen is diffused out of the stomata. The glucose is transported through the phloem to all parts of the plant aiding in their growth.
