1. Most organisms go through a cycle of growth, development, and division
The Cell Cycle
Most organisms go through a cycle of growth, development, and division

2. Phases of the cell cycle
Interphase
Mitotic Phase

3. Interphase G1- a cell grows and develops
S- a cell continues to grow but copies its DNA
G2- still growing but begins to store energy and get ready to divide

4. Mitotic Phase Has two stages mitosis (the nucleus divides)
cytokinesis ( the cytoplasm divides)

6. Phases of Mitosis
Prophase
Metaphase
Anaphase
Telophase

7. Prophase

8. Metaphase

9. Anaphase

10. Telophase

11. Cytokinesis In an animal cell
the membrane contracts in the middle and forms a furrow. It eventually divides the cell into two cells
In a Plant cell
a new cell wall forms in the middle of a plant cell
organelles join together to form a cell plate
the cell plate grows and becomes two new cells

12. Animal Cell vs Plant

13. Unicellular Organisms
made of only 1 cell
can be eukrayotes (nucleus)
or prokaryotes (no nucleus)
These can be algae or different kinds of fungi

14. Multicellular Organisms
Made of many Eurkaryotic cells that work together
Each cell has a specific job
The cells are differentiated

15. Stem Cells
watch
are unspecialized cells that are able to play into many different cell types
In your bone marrow there are a dozen different kinds of stem cells that help you replace worn out or damaged cells from your muscles
watch

16. Plant Cells also have unspecialized cells
they are grouped in areas called Meristems
different types of plant cells have different jobs like
making food
storing food
protecting the plant

17. Tissues groups of cells make up tissues
Tissues- work together to carry out specific tasks
Animal
Plants
dermal
muscle
vascular
nervous
ground tissue
epithelial

18. Organs groups of tissues work together to form a particular job
Plants
leaves
etc.
Animals
heart
lungs
brain etc.

19. Organ Systems
organs work together to make a system to complete a series of tasks
Ex: your digestive system works to digest your food using your digestive organs
Plants have two organ systems ( shoot system & root system)

20. Organism
organs systems work together to carry out jobs for the survival of an organism
Humans have 11 different body systems to keep us working
