About Lesson
Chapter 01 – Cellular Organization of Plants and Animals
What is a cellular organization of plants and animals?
In multicellular organisms, cells work in groups. A group of cells performing the same function is called a tissue. Plants and animals have different tissues in their bodies. Epidermal tissue covers the roots, stem and leaves of a plant.

Chapter 03 – Photosynthesis and Respiration in Plants
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide.

Chapter 05 – Atoms, Molecules, Mixtures, and Compounds
An atom is the smallest part of an element that can exist. Compounds are formed from elements by chemical reactions. Compounds contain two or more elements chemically combined in fixed proportions and can be represented by formulae using the symbols of the atoms from which they were formed.

Chapter 12 – Space and Satellites
A satellite is an object in space that orbits or circles around a bigger object. There are two kinds of satellites: natural (such as the moon orbiting the Earth) or artificial (such as the International Space Station orbiting the Earth).
