Cells and respiration Flashcards
Two types of microscopes
Light microscope
Electron microscope (can look at subcellular structures)
Subcellular structures in Plant AND animal cells
Mitochondria
Nucleus
Ribosomes
Cytoplasm
Cell membrane
Subcellular structures ONLY in plant cells
Cell wall
Chloroplasts
Vacuole
Examples of unicellular organisms
Amoeba
Euglena
Function of cell wall, chloroplasts and vacuole?
Cell wall - stops cell from bursting
Vacuole - stores cell sap
Chloroplast - site of photosynthesis
Definition of
Tissue
Organ
Organism
Tissue - made of lots of same kind of cell
Organ - made up of different tissues
Organism - made of different organs
What is respiration
Process of releasing energy
Occurs in mitochondria
Two types - aerobic (uses oxygen) and anaerobic
What is respiration used for
Making proteins
Keep warm
Muscle contraction
Equation for aerobic respiration
Glucose + oxygen -> carbon dioxide + water
What is Anaerobic respiration
Doesn’t use oxygen
Less efficient
Releases less energy
Equations for anaerobic respiration in plants and animals
Plants:
Glucose -> carbon dioxide + ethanol
Animals:
Glucose -> lactic acid
