|
What are the four stages of meiosis in order? |
Prophase Metaphase Anaphase Telophase |
|
|
What is the name of the fluid which supports the cell and houses the organism? |
Cytoplasm |
|
|
What is the difference between the rough endoplasmic reticulum and the smooth endoplasmic reticulum? |
Rough has ribosomes attached |
|
|
What does the Golgi body do? |
Responsible for packaging and secretion of products produced within the cell |
|
|
What type of cells are produced in meiosis? |
Four daughter cells (haploid) |
|
|
What are ribosomes responsible for? |
Protein synthesis |
|
|
What are lysosomes responsible for? |
Collection of digestive enzymes in membrane sacs. Forms part of the defence mechanism of the cell. |
|
|
What happens in prophase? |
Chromosomes become apparent and nucleus begins to die |
|
|
What happens in metaphase? |
Chromosomes line up in the middle of the cell and spindle apparatus connects to centromere and spindle fibres begin to form |
|
|
What happens in anaphase? |
Replicated chromosomes are split and moved to opposite sides of the cell. Chromosomes go back to being ‘thread like’ |
|
|
What happens in telophase? |
Duplicated material carried in parent cells is separated into two identical daughter cells |
|
|
What does active transport need? |
Energy |
|
|
How would you describe a haploid cell? |
A cell that contains a single set of chromosomes |
|
|
What is a diploid cell? |
A cell which contains two sets of chromosomes |
|
|
Where does meiosis take place? |
Within the gonads to produce ova or sperm |
|
|
Which body cell does mitosis occur in? |
Somatic cells |
|
|
Which body cell type does meiosis occur in? |
Germ cells |
|
|
When does ‘crossing over’ occur in meiosis? |
Prophase 1 |
|
|
What is the difference between active and passive transport? |
Active DOES need energy Passive DOES NOT need energy |
|
|
Where are proteins synthesised in the cell? |
Ribosomes |
|
|
Where are protein molecules the main structural element? |
Centrioles |
|
|
What are the parts of the plasma membrane involved in cell recognition called? |
Glycoproteins |
|
|
Where does aerobic respiration take place? |
Mitochondria |
|
|
What is it possible to observe under a light microscope? |
Living organisms |
|
|
What is the Golgi apparatus the site of? |
Protein modification |
|
|
When using a microscope how is it most common to measure a specimen in? |
Micrometers |
|
|
What is an example of a prokaryote? |
A bacterial cell |
|
|
What is an intracellular sodium potassium pump an example of? |
Active transport |
|
|
Glucose crosses cells membranes thought protein channels by? |
Facilitated diffusion |
|
|
What can increase the rate of diffusion of molecules? |
Temperature increase |
|
|
What is the water potential of pure water? |
0 |
|
|
What happens when a red blood cell is placed in a hypotonic solution |
It swells |
|
|
How do particles move during active transport? |
Against a concentration gradient and energy is used |
|
|
What is the formation of a new DNA strand catalysed by an enzyme called? |
Polymerase |
|
|
What is the cytoplasm? |
Inner substance of the cell excluding the nucleus. |
|
|
What is the fluid of the cell called? |
Cytosol |
|
|
What are the organelles within the cell? |
Nucleus Mitochondria Endoplasmic reticulum Ribosomes Golgi apparatus Lysosome Peroxisomes |
