Cells Flashcards
What structure do plant cells contain?
- cell wall
- cell membrane
- mitochondria
- nucleus
- ribosome
- chloroplast
- vacuole
- cytoplasm
What is the function of the nucleus?
Controls the activity of the cell and contains DNA
What is the function of the cytoplasm?
Most chemical reactions take place there
What is the function of the cell membrane?
Controls the passage of substances in / out if the cell
What is the function of the mitochondria?
Energy is released through respiration
What is the function of the ribosomes?
Protein synthesis occurs here
What is the function of the chloroplasts?
Absorbs light energy and makes food
What is the function of the vacuole?
contains cell sap
What is the function of the cell wall?
Gives cell shape and protection
What structures do bacteria cells contain?
- cell wall
- cell membrane
- ring of plasmid DNA
- ribosome
- large chromosomal of DNA
- flagella
What structures do yeast cells contain?
- cell wall
- cell membrane
- mitochondria
- ribosome
- cytoplasm
- nucleus
What is diffusion?
The spreading of particles or gas.
Movement from a religion of higher concentration to one of lower concentration
The greater the difference in concentration, the ? the rate of diffusion?
The FASTER the rate of diffusion
Where does the oxygen required for respiration pass through?
The cell membrane
What structure do animal cells contain?
- nucleus
- mitochondria
- ribosomes
- cytoplasm
- cell membrane
