Cells 2 Flashcards
What is the function of a nucleus in a plant or animal cell?
Contains genetic material that controls activities of the cell
What is the function of a cytoplasm in a plant or animal cell?
A substance where most of the chemical reactions take place in the cell. Enzymes control these reactions
What is the function of a cell membrane in a plant or animal cell?
Holds cell together and controls what goes in and out of the cell
What is the function of a mitochondria in a plant or animal cell?
Where most of the reactions for respiration take place
What is the function of ribosomes in a plant or animal cell?
Where the proteins are made in the cell
What else do plant cells contain which animals do not have?
Rigid cell wall, permanent vacuole and chloroplasts
What is the role of a rigid cell wall in a plant cell and what is it made out of?
Cellulose. Supports and strengthens cell
What does a permanent vacuole contain in a plant cell?
Cell sap –> weak solution of sugar and salts
What is the role of chloroplasts in a plant cell and what are they made out of?
Chlorophyll. Absorb the light energy during photosynthesis
What type of organism is a yeast organism and what is it made out of?
Microorganism. Made up of a nucleus, cell wall, cell membrane and cytoplasm
What type of organism is a bacteria and what is it made out of?
Microorganism. Contains a cytoplasm, cell membrane surrounded by a cell wall
If a bacteria cell doesn’t have a nucleus, what happens to their genetic material instead?
Floats around in the cytoplasm. Some of the genes are found in plasmids
