This document provides an overview of living things, specifically plants. It explains that all living things are made of cells and have three vital functions: nutrition, interaction, and reproduction. It describes the structure of living things from single-celled organisms to multicellular organisms made of tissues, organs, and systems. The document defines plants as multicellular organisms that produce their own food through photosynthesis, do not move but react to changes, and most reproduce using flowers and seeds. It also outlines plants' nutrition process of absorbing water, minerals, carbon dioxide and making carbohydrates using sunlight.

2. • Living things
• The characteristics of living things
All living things are formed of cells and have
three vital functions: nutrition, interaction and
reproduction.

4. • Living things
• The structure of living things
The simplest living things are single-cell
organisms. All the vital fuctions happen in their
one cell.
In multicellular organisms, cells group together
to form: tissues, organs and systems.
Single-cell organism Multicellurar organisms

5. • Plantas
• The characteristics of plants
Plants are multicellular organisms that produce
their own food.
Plants do not move from place to place but they
react to changes around them.
Most reproduce by flowers which produce
seeds.

6. • Plantas
• The nutrion function in plants
Plants absorb water, minerals and carbon
dioxide. Using the Sun´s light they make
carbohydrates through photosynthesis. Plants
also breathe and excrete residues.
