The biosphere is the part of Earth where living organisms exist. All organisms perform the basic life processes of interaction, nutrition, and reproduction. A cell is the basic unit of life, and cells perform the three life processes. Cells have three main parts - a nucleus, membrane, and cytoplasm. While bacteria are unicellular, butterflies are multicellular organisms composed of more than one cell.

1. The BIOSPHERE is the part of the
Earth where we can find living
organisms

2. • There are many different types of organisms
but ALL of them perform the basic life
processes.
INTERACTION NUTRITION REPRODUCTION

3. INTERACTION
• Living things detect information.
• Humans get information about the world
using the 5 senses.
• Living things react to this information.

4. NUTRITION
• All living things take nutrients ( food, water,
light, air) to survive.
• Living things get energy and grow thanks to
nutrition.

5. REPRODUCTION
• Living things reproduce themselves.

6. CELLS

7. CELLS
• A cell is the basic unit of life.
• You need a microscope in order to see it.

8. • Cells are living things. They perform the 3 life
processes.
• They reproduce by dividing themselves.
• They have 3 main parts
1. NUCLEUS
2. MEMBRANE
3. CYTOPLASM

9. TYPES OF CELL
• BACTERIAS HAVE ONLY ONE CELL. THEY ARE
UNICELLULAR
• BUTTERFLIES, HAVE GOT MORE THAN ONE
CELL. THEY ARE MULTICELLULAR

10. CELL MEMBRANE: SURROUNDS
AND PROTECT THE CELL
CYTOPLASM: IS A LIQUID THAT IS
INSIDE THE MEMBRANE. YOU
CAN FIND THE NUCLEOUS AND
THE ORGANELLES
NUCLEOUS: CONTROLS EVERYTHING
ANIMAL CELL

11. PLANT CELL
CHLOROPLAST

12. PARTS OF THE CELL QUIZ
• MEMBRANE
• NUCLEOUS
• CHLOROPLAST
• CYTOPLASM
• CONTROLS EVEREYTHING
• CLEAR LIQUID INSIDE THE
MEMBRANE
• SURROUNDS AND
PROTECTS THE CELL
• SPECIAL ORGANELLES IN
THE PLANT CELL

13. HOW ARE CELLS ORGANIZED?

14. CELLS WORK TOGETHER
