Draw Conclusion
What types of data would you collect for Step Two
Scientific Data or Observable Facts
This variable is known as the “response”, “ symptom” or “effect”
Dependent Variable
This variable is not affected by anything in the study and stand alone
Independent Variable
This variable can also be known as the “cause”
Independent Variable
A group that has not been tampered within a study
Control Group
A structure that keeps cells inside and separates from the external environment//( like a wall)
Cell Membrane
The Cell membrane is __________ which means that it can allow certain things through such as water and nutrients
Selectively Permeable
Plant Cells, do or don’t have a cell wall
yes
Animal Cells, do or don’t have a cell wall
no
What is the goo like substance inside of the Cell Membrane
Cytoplasm
Ribosomes function
produces proteins
Genetic Material
Coded instruction for carrying out cell function
Does Bacteria contain coded material?
Yes
Carries genetic material that is a single molecule into the cytoplasm
/prokaryote
Bacteria
Vacuole
Stores water, nutrients, wastes and other substances
Mitochondrion
Cell’s energy is stored here
nucleus contains what
contains genetic material direct to the activities of the cell
First stage of photosynthesis
Light energy is captured by the coroplasts inside of the plant cell
Second stage of photosynthesis
Water from the soil and the CO from the air undergo a series of chemical reactions inside of the chloroplasts. The product of these reactions would be, oxygen * not used by the plant * and energy
In simple terms what does this mean
6CO2 + 6H2O → C6H12O6 + 6O2
carbon dioxide plus water, in the presences of light energy produces glucose PLUS oxygen
As a result of photosynthesis, energy is stored in _____ and other __________ in the plant
sugars and carbohydrates
When energy is needed in a cell, carbohydrates are broken down to release the energy in a process called
cellular respiration
cellular respiration is when
oxygen from the air reacts with glucose from food to yield carbon dioxide, water, and energy.
C6H12O6 + 6O2 → 6CO2 + 6H2O + energy
Cellular respiration as a chemical equation
in simple terms what does this mean,C6H12O6 + 6O2 → 6CO2 + 6H2O + energy
In words, this means that glucose plus oxygen yields(or produces) carbon dioxide, water, and energy.
