--- title: How plants make their food — a lesson of Mova's school · trees and pragmatics description: «How plants make their food», a lesson of the world course of Mova's primary school, sentence by sentence with dependency trees and pragmatics. It begins: Plants make their own food in a process called photosynthesis, which means "putting together with light". --- [Mova](https://md.mova.elamur.ai/free/en/) · [this page in HTML](https://mova.elamur.ai/free/en/corpora/school/world/22-photosynthesis/) [home](https://md.mova.elamur.ai/free/en/) / [corpora](https://md.mova.elamur.ai/free/en/corpora/) / [school](https://md.mova.elamur.ai/free/en/corpora/school/) / [World](https://md.mova.elamur.ai/free/en/corpora/school/world/) / How plants make their food # How plants make their food Lesson 22 of the world course of Mova's primary school: 17 sentences, each with its syntax tree and pragmatics.

How Mova does on its tests: [the lesson at school](https://md.mova.elamur.ai/free/en/school-run/world/22-photosynthesis/). - [0](https://md.mova.elamur.ai/free/en/corpora/school/world/22-photosynthesis/0/) — Plants make their own food in a process called photosynthesis, which means "putting together with light". - [1](https://md.mova.elamur.ai/free/en/corpora/school/world/22-photosynthesis/1/) — A leaf takes in carbon dioxide gas from the air through tiny holes, and water comes up from the roots through the stem. - [2](https://md.mova.elamur.ai/free/en/corpora/school/world/22-photosynthesis/2/) — Using the energy of sunlight, caught by a green substance called chlorophyll, the leaf turns the water and carbon dioxide into sugar, the plant's food, and gives out oxygen. - [3](https://md.mova.elamur.ai/free/en/corpora/school/world/22-photosynthesis/3/) — So a plant is mostly built from air and water, not from soil: a huge oak tree is made mainly of carbon taken from the air. - [4](https://md.mova.elamur.ai/free/en/corpora/school/world/22-photosynthesis/4/) — The oxygen that plants and tiny sea algae, simple plant-like living things, give out is the oxygen that animals and people breathe. - [5](https://md.mova.elamur.ai/free/en/corpora/school/world/22-photosynthesis/5/) — Photosynthesis is how green plants make their own food. - [6](https://md.mova.elamur.ai/free/en/corpora/school/world/22-photosynthesis/6/) — Plants need light, water and carbon dioxide to make food. - [8](https://md.mova.elamur.ai/free/en/corpora/school/world/22-photosynthesis/8/) — Most leaves are wide and flat so that they catch as much light as possible. - [9](https://md.mova.elamur.ai/free/en/corpora/school/world/22-photosynthesis/9/) — Chlorophyll is the green substance in leaves that catches the energy of light. - [10](https://md.mova.elamur.ai/free/en/corpora/school/world/22-photosynthesis/10/) — The food a plant makes is a kind of sugar. - [11](https://md.mova.elamur.ai/free/en/corpora/school/world/22-photosynthesis/11/) — Photosynthesis gives out oxygen into the air. - [12](https://md.mova.elamur.ai/free/en/corpora/school/world/22-photosynthesis/12/) — Plants also breathe, using some oxygen, all day and night, but in daylight they make much more oxygen than they use. - [13](https://md.mova.elamur.ai/free/en/corpora/school/world/22-photosynthesis/13/) — Plants cannot make food in the dark. - [14](https://md.mova.elamur.ai/free/en/corpora/school/world/22-photosynthesis/14/) — Plants store extra sugar as starch, for example in potatoes and grains. - [15](https://md.mova.elamur.ai/free/en/corpora/school/world/22-photosynthesis/15/) — Most of the mass of a tree comes from carbon dioxide from the air and water, not from the soil. - [16](https://md.mova.elamur.ai/free/en/corpora/school/world/22-photosynthesis/16/) — Tiny algae in the oceans make a large part of the world's oxygen. - [17](https://md.mova.elamur.ai/free/en/corpora/school/world/22-photosynthesis/17/) — All the food animals eat comes, directly or through other animals, from plants and algae. - ← previous: [Parts of a plant and what each does](https://md.mova.elamur.ai/free/en/corpora/school/world/21-parts-of-a-plant/) - next →: [Flowers, pollination and how seeds travel](https://md.mova.elamur.ai/free/en/corpora/school/world/23-flowers-and-seeds/) - ↑ back to [World](https://md.mova.elamur.ai/free/en/corpora/school/world/)
