1. Science TAKS Review

2. I want plants to grow faster
Independent Variable –
the thing I change
Water plants different amounts
Control / constant –
Do not change- all plants in same location, get same amount of dirt and sunlight. Etc…
Dependent Variable –
Did the plants grow any faster with change in water

3. 2 types of cells Prokaryote – no nucleus Kingdoms: Eubacteria and
Archaebacteria
Eukaryote
- have nucleus
Kingdoms: Plant,
Animal, Protista &
Fungi
Cut out Organelle - "Small organs" found within a cell that carryout cell functions that are essential for cell survival.

4. Cell Structures and Functions
Cell Membrane - barrier
Nucleus – DNA
Cytoplasm- “blood” of cell
Ribosome- protein maker
Mitochondria- energy maker
Chloroplast- make sugar and O2

5. Cellular Processes Homeostasis – balance or same Water temperature
blood pressure

6. Permeability
Diffusion - movement from high concentration to low concentration

7. Osmosis – movement of water

8. Deoxyribonucleic Acid (DNA)
Nitrogen bases (Thymine, Adenine, Guanine, Cytosine) determines the inherited traits.
A  T
G  C C G T A

9. DNA Replication
One strand of DNA reproduces to make two strands so the cell can reproduce.

10. Ribonucleic Acid (RNA) 11th
Transcription A U GC

11. Ribonucleic Acid (RNA) 11th
Translation
Amino acids are linked together to make a protein.
3 bases needed for 1 codon

12. Six Kingdoms of Life Archaebacteria – Extreme bacteria
Eubacteria – Bacteria
Protista – Amoebas, paramecium
Fungi – Mushrooms, molds, yeast
Plantae – Trees
Animalia – Mammals—uhhhh people
microscopic

13. Single cell vs. Multi-cell
Bacteria
Protista – little guys you look at under microscope
Fungi – mushroom
Plant
Animal

14. Heterotroph vs. Autotroph -eat something -make own food
Animalia
Fungi
Plantae
BOTH
Bacteria
Protista

15. Body Systems Circulatory – heart / blood - Oxygen / food
Digestive – breaks down food
Nervous – electrical signals
Endocrine – hormones
Reproductive – sex
Integumentary – Skin
Skeletal – Bones - Structure
Respiratory – Lungs - Oxygen in, CO2 out
Muscular - Movement
Excretory – Eliminates wastes - Urine
Immune – Kills viruses
