The basic unit of structure for all living things!
Dec 28, 2015
Theory – well tested hypothesis.
1.All living things are made up of cells.
2.Cells are the basic unit of structure and function in living things.
3.New cells come from existing cells.
Eukaryotic Cell – a cell that contains a membrane bound nucleus and many specialized structures called organelles “tiny organs”
Single Celled – organisms made up of 1 cell (ex. amoeba, paramecium, euglena)
Multicellular – organisms made up of many independent cells working together (plants and animals)
Function – protection & controls what enters and leaves cell.
Structure – double layered Phospholipid membrane
Function – holds all organelles and nutrients.
Structure – semi-solid fluid (water, proteins, various nutrients)
Function – Protects the DNA
Structure – phospholipid membrane (nuclear envelop) & internal fluid called nucleoplasm.
Function – constructs lipids and special proteins (enzymes) for detoxification
Structure – folded phospholipid membrane
Function – modifies proteins and packages them to be shipped out.
Structure –phospholipid membrane found in stacks.
Function – power house of cell – place where food is broken down and turned into energy.
Structure – phospholipid membrane
Plant Cells OnlyPlant Cells Only
Function – makes food (sugars)
Structure – phospholipid membrane
Function – protection and support
Structure – cellulose (carbs.)
Function – relays messages from one part of the body to another
Structure – brain, spinal cord & peripheral nerves
Function – brings oxygen in and carbon dioxide out.
Structure – nose, trachea, pharynx, bronchi and lungs
Function – converts foods into molecules that can be used by body.
Structure – mouth, esophagus, stomach, and intestines
Function – produces sperm & egg cells.
Structure – testes & penis; ovaries, fallopian tubes, uterus and vagina.
