Cell Structure Flashcards
(23 cards)
Is photosythesis exothermic or endothermic?
Endothermic.
What is the role of the ribosomes?
To perform protein synthesis.
Give the balanced symbol equation for photosynthesis.
6 CO2 + 6 H2O ===> C6H12O6 + 6O2
Are bacteria eukaryotic or prokaryotic?
Prokaryotic.
Are plants eukaryotic or prokaryotic?
Eukaryotic.
What is the function of the mitochondria?
To release energy for the cell to use by aerobic respiration.
True or false: Animals are eukaryotic.
True.
What is cytoplasm?
A jelly-like material containing nutrients and salts, where chemical reactions take place
What is the cell wall made of in plant cells?
Cellulose.
What process do chloroplasts perform?
Photosynthesis, using light energy from the sun.
Give the balanced symbol equation for aerobic respiration.
C6H12O6 + 6O2 ==> 6 CO2 + 6 H2O
Name 3 subcellular structures found in plant cells but not animal cells.
- Chloroplasts
- Permanent Vacuole
- Cell Wall
True or false: Bacteria are multicellular.
False
What are the two reasons animals cells prefer aerobic respiration to anaerobic respiration?
- Anaerobic respiration does not fully break down the glucose molecule, so less energy is released.
- Anaerobic respiration produces lactic acid which can damage cells and leads to an oxygen debt.
What is the cell wall made of in bacterial cells?
Peptidoglycan.
What are the short loops of genetic material found in bacteria that contain non-essential genes called?
Plasmids.
What is the product of anaerobic respiration in animals?
Lactic acid.
Which is larger: A bacterial cell or a plant cell.
Plant cell.
What is the function of the cell wall in plant cells?
To keep the shape and structure of the cell rigid.
Is respiration exothermic or endothermic?
Exothermic.
The _____ contains the genetic material in eukaryotic cells. What one word completes the senctence?
Nucleus.
The vacuole contains _______.
Cell sap.
What is the product of anaerobic respiration in plants and fungi?
Ethanol.
