128 Multiple choice questions
Term 1 of 128
Describe the difference between gram positive and gram negative?
Gram negative has thin cell walls so the ethanol washes out the crystal violet, so they
appear safranin pink. Gram positive appears purple
Gram positive cells have a thick outer membrane that prevents staining
Gram negative cells are larger and more complex than gram positive
Gram positive has no cell wall and is resistant to antibiotics
Term 2 of 128
What is the structure of the plasmodesmata?
Thin membranes that facilitate cell division
Solid barriers that protect the cell from pathogens
Microscope channels which cross the cell walls of plant cells
Large openings that allow for nutrient absorption
Term 3 of 128
How the structure of a neutrophil enables it to exit the capillary in order to reach the bacteria?
It has a flexible nucleus this makes it fit through the pores and squeeze into smaller spaces
It has a large size that allows it to push through the capillary walls easily.
It has a rigid structure that prevents it from moving through tight spaces.
It has a thick outer membrane that protects it from bacteria.
,Term 4 of 128
What is magnification?
the clarity of an image when viewed under a microscope.
the ratio of an object's image size to its real size
the size of an object compared to the size of the microscope.
the distance between two objects in a microscope view.
Term 5 of 128
What is the structure of the centrioles?
They are large spherical organelles that store nutrients
They are solid structures that provide rigidity to the cell
A stack of membrane bound flattened sacs
They are small tubes of protein fibres
Term 6 of 128
Describes the function of the squamous epithelial tissue
It is a specialized tissue that produces hormones and regulates metabolism
It is one cell thick and forms thin, smooth, flat layers, ideal for rapid diffusion
It is a dense tissue that stores fat and provides insulation
It is a thick layer of cells that provides structural support and protection
,Term 7 of 128
What is the resting potential of a neuron?
A neuron is actively sending signals to other neurons
A neuron is not is not transmitting an action potential and is at rest
A neuron is in a state of hyperactivity and firing continuously
A neuron is undergoing repair after an injury
Term 8 of 128
Describe how a light microscope works
It has a flexible nucleus this makes it fit through the pores and squeeze into smaller spaces
Light microscopes use ultraviolet light and mirrors to project images onto a screen
Light microscopes utilize lasers to cut specimens into thin slices for viewing
Light microscopes use visible light and magnifying lenses to observe small objects
Term 9 of 128
What is the function of the Golgi apparatus?
Transport of nutrients across the cell membrane
Degradation of cellular waste
Synthesis of ribosomal rna
Modified and packaged proteins into vesicles for transport
, Term 10 of 128
What is an organelle?
It's a group of cells that work together to form tissues.
It's a fluid that fills the space between cells in an organism.
It's specialised structures found within a living cell
It's a type of organism that can survive in extreme conditions.
Term 11 of 128
What does the central nervous system consist of?
the outer protective layer of the brain
the part of the body that controls muscle movement
the network of blood vessels in the body
brain and spinal cord, it is made up of many non-myelinated nerve cells and longer
myelinated scone and dendrons that carry nerve impulse
Term 12 of 128
What is the function of the plasmodestmata?
To synthesize hormones for growth
To store waste products of the cell
To allow materials to pass through the cell wall
To provide structural support to the cell
