Bio Cell Stuff Flashcards
What are the major elements on the periodic table that are involved in cell structures?
Carbon, Hydrogen, Oxygen, Phosphorus, and Nitrogen (sulfur)
What are the 4 major organic compounds?
Lipids, Carbs, Protein, Nucleic Acids
What are lipids?
Fate and oils
What are carbs?
Sugars, starches, and cellulose
What is Protein?
Amino acid residue; e.g enzymes muscle fibers
What are nucleic acids?
DNA and Genetic Material
What is the major compound found in all plant and animal cells?
Water
What are the trace elements that are nutrionally essential?
Magnesium, Zinc, Maganese, and Iron
What are centrioles
In animal cells, responsible for cell division(Miosis and Mitosis)
Why do plant cells not need hemoglobin?
Plant cells do not need oxygen.
How is energy generally stored in plants
Starch or oils
How do animals usually store energy
Glycogen(stored glucose essentially), lipids (i.e. fats) (basically lipids and carbs)
What is DNA made up of in both animal and plant cells?
Sugars, nitrogen bases and phosphate
What is the cell membrane do?
Semi-permeable, maintains equilibrium in the cell. Composed of a phospholipid bilayer.
What part of the cell membrane is hydrophilic
The phosphate balls, ‘the polar ends of the phospholipid molecules’
What is the hydrophobic part of the cellular membrane?
The tails, composed of Fatty acids
What is another name for the cell membrane?
Plasma membrane (contains plasma, semi fluid living matter)

THREE 0, P IN THE MIDDLE OH AT THE CORNER
Where are proteins found in the cell membrane?
Literally everywhere.
What is the cell membrane useful for?
To transport gases, nutrients and wastes in and out the cell. ALL SUBSTANCES MOVING IN AND OUT ARE CONSIDERED PARTICLES
Mosaic meaning
Collection of different substances held together by a common material
PARTICLE THEORY OF MATTER #1
All matter is made of particles; can vary in size and composition due to the substance
PARTICLE THEORY OF MATTER #2
The particles of matter are constantly moving; move least in solids, most in gases. Adding energy (heat) can affect movement.
PARTICLE THEORY OF MATTER #3
The particles of matter are attracted to one another or are bonded together
