MORE DECKS TO EXPLORE
PRESENTATION OUTLINE
A CELL IS...
- The smallest unit of an organism
- All living things are made up of cells
- Its microscopic
- Consists of cytoplasm, nucleus, and a membrane
- Either eukaryotic or prokaryotic.

EUKARYOTIC VS. PROKARYOTIC
- Eukaryotic- contains a nucleus and other structures in the cell.
- Prokaryotic- lacks a membrane, mitochondria, etc.
- Prokaryotic cells don't have membrane bound organelles.
CELLULAR RESPIRATION
- Set of metabolic processes
- Convets biochemical energy into ATPs.
- Releases waste products

UNICELLULAR & MULTICELLULAR
- Unicellular is a single celled organism
- Multicellular is an organism with many cells
- In a unicellular organism, one cell does all processes.
- In a multicellular organism, many cells do many processes.
PROCESSES OF LIFE
- Movement- the ability to move to survive.
- Nutrition- living things take in materials for growth.
- Growth- living things increase in size and number.
- Reproduction- living things produce new living things.

PROCESSES OF LIFE CONT...
- Excretion- living things remove wast products.
- Transport- Absorption and Circulation
- Synthesis- smaller organisms combined chemically.
- Respiration- breaking down nutrientso give off chemical energy.
- Regulation- a living thing controls and coordinates its activities.
CHLOROPLAST
- Only in green plant cells
- A plastid that contains chlorophyll
- Photosynthesis takes place.

PHOTOSYNTHESIS
- Converts solar energy into chemical energy
- Chemical energy is used to fuel activities performed by the organism.
