Topic 1-4 Flashcards
What does the Cell Membrane in a plant cell do?
Responsible for determining which bits go in and out of the cell.
What does the Cell Wall in a plant cell do?
Important for structure.
What does the Vacuole in a plant cell do?
Important for structure.
What does the Ribosomes in a plant cell do?
Responsible for protein synthesis.
What happens in the Cytoplasm in a plant cell?
Where most reactions take place.
What happens at the Chloroplasts(green) in the plant cell?
Absorb sunlight to produce food for the plant.
What happens at the Mitochondria(pink) in the plant cell?
Energy is produced.
What does the Nucleus of the plant cell do?
Stores DNA, acts as a command center.
What does the Nucleus of the animal cell do?
Where DNA is held, control center of cell.
What does the Cell Membrane of the animal cell do?
Controlling what goes in and out of the cell.
What does the Mitochondria(pink) of the animal cell do?
Energy is produced.
What does the Cytoplasm do in an animal cell?
Where most reactions take place.
What features inside the cell do animal and plant cell not share?
Cell wall, vacuole and chloroplasts.
What does the Cell Membrane do in a bacterial cell?
Controlling what goes in and out of a cell.
What happens in the Cytoplasm in a bacterial cell?
Where most the reactions take place.
Why is the Chromosome/DNA different from a plant or animal cell in a bacterial cell?
The chromosome/DNA in a bacterial cell is not in the nucleus.
What do the Ribosomes do in a bacterial cell?
Responsible for protein synthesis.
What do the Cell Wall do in a bacterial cell?
Important for structure.
What does the Flagella do in a bacterial cell?
Help the structure to move.
What specialises cells?
Differentiation.
How did microscopes vary over the years?
First started off with a basic lens, then moved onto a more complex array of lenses that we now use at school. To the electron microscopes which are massive and controlled by computers.
Magnification equation?
Magnification = Image height / Object heigh (MIA)
What is DNA?
DNA is a long strand of deoxyribonucleic acid, made up of lots of letters; A, T, C, G. These twist round to make a double helix. It’s so long it twists round into a chromosome, which is located in the nucleus of the cell.
What happens in mitosis?
In mitosis we go from one parent cell, to two identical daughter cells.
