This document discusses the basic characteristics of living things. It defines the biosphere as the part of Earth inhabited by living organisms, and outlines three basic life processes: interaction, nutrition, and reproduction. It then provides examples of these processes in human beings and cells. The document also introduces the hierarchical organization of cells into tissues, organs, and systems, and outlines the five kingdoms used to classify living things: Monera, Protist, Fungi, Plant, and Animal.

1. LIVING THINGS
BY : PEDRO SÁNCHEZ HERNÁNDEZ

2. LIFE ON EARTH
.BIOSPHERE: is the part of the Earth where we can find living organisms.
.BASIC LIFE PROCESSES:
Interaction: detect information and they also react
Reproduction: can create new members of
their own species
Nutrition: take nutrients. These nutrients give
energy

3. Human beings
Interaction: Our senses to detect information about the world; communicate with
other; move around and do many things
Nutrition: breathe air; drink water and eat food; eliminate waste products
Reproduction: born; have children; produce milk for their babies

4. CELLS: are living things because they perform the basic life processes of interaction,
nutrition and reproduction.
Animal Cell
Nucleus: controls
everything
Cytoplasm: is a thick,
clear liquid, inside the
membrane
Membrane: protects
the cell

5. Plant Cell
Nucleus
Cytoplasm
Membrane
Chloroplast

6. How are cells organised?
Cell
System
Tissue
Organ

7. The five kingdoms
Moneran kingdom: unicellular organisms, bacteria
Protist kingdom: unicellular or multicellular,
protozoans and algae (they make their own food)

8. Fungus kingdom: unicellular or multicellular, yeast and mushrooms
Plant kingdom and Animal kingdom: multicellular. The plants make own food
