Day #1 Living things
Living things
1. can reproduce either sexually (2 parents) or 1 parent (asexually)
2.
can grow and develop ( not just bigger, also more complex)
3. have similar chemicals – water, carbohydrates, proteins
4. _____________________________
5. _______________________________
6. are made of one or more CELLS
Where did living things come from?
•
For hundreds of years, it was believed that living things could sometimes
come from non-living things:
Ex: mice were created by a pile of straw
Ex: Maggots are created by a chunk of rotting meat
This belief was called: _______________________________________
Francesco ___________________ conducted one of the first controlled
experiments in order to disprove this theory.
Draw results
Jar #1 open
Before
Jar #2 netting
Jar #3 close
After
Jar #1 open
Jar #2 netting
Jar #3 close
His results:
The maggots only appeared if they could land on the meat (open jar)
•
or if they could smell the meat inside (netting).
•
Living maggots only came from living flies.
Cells
Cell theory
all living things are made up of __________________________

Photosynthesis and Respiration
_______________: plant cells making glucose for energy
light
6 CO2 + 6H2O
carbon water
dioxide
→
C6H12O6
glucose
+
6O2
oxygen

The cell part where photosynthesis occurs is _________________

This process opposite of photosynthesis is respiration
_________________: all cells release energy when they “burn” fuel/food
C6H12O6 + 6O2 →
glucose
oxygen
water
6 CO2 + 6H2O
carbon
dioxide

The cell part where respiration occurs is ______________________

Mitosis
Mitosis produces ___________________ daughter cells
Mitosis: Fill in the circles:
Interphase- cell prepares for division
Prophase - nucleus disappears
Metaphase - chromosomes lined up in the middle
Anaphase- chromosomes separate and move to opposite ends
Telophase - The cell divides into two
Cytokinesis- Cell divided into two cells and nucleus reforms.
Meiosis: produces daughter cells that have one half the number of
chromosomes as the parent cell.A cell undergoing meiosis will divide
______________ times

Diffusion- Particles moving from an area of high concentration to an
area of low concentration
Draw Diffusion before and after:
The movement of H2O across semi-permeable from high concentration to
low concentration
Draw Osmosis before and after:


Osmosis- H2O moved into cell.
Diffusion- Salt moves out of the Cell
Genetics Notes
Chromosome- rod shaped structured that contains DNA
DNA- made up of many genes strung together
Karyotype________________________________________________________________
________
Draw 2 chromosome and label them
Scientists pair up all chromosomes and check for any abnormalities

Extra chromosome on gene 21 is ______________________________
