cell biology
cell structure
cell membrane - holds the cytoplasm and controls what ever enters and leaves the cell
mitochondria - structures in the cytoplasm where energy is produced
ribosomes - small structure in the cytoplasm where protein synthesis occurs
cell wall - a protective layer that helps support the cell
cellulose - a carbohydrate that makes up the cell wall of plants
vacuole - a fluid-filled cavity in a cell that is used for storage
chloroplast - a structure containing chlorophyll found in plants and algae
prokaryotic - organism without a nucleus or organelles such as mitochondria
cytoplasm - substance outside the nucleus where chemical reactions take place
eukaryotic - cell with a nucleus and sub-cellular organelles such as mitochondria
nucleus - the control centre of the cell
plasmid - a small piece of DNA separate from the main bacterial chromosomes
cell division
mitosis -
stem cell -
cell cycle - the series of growth and division event during a cells life
embryonic stem cells -
gene - part of a chromosome, made of DNA, which codes for protein
adult stem cells -
DNA - nucleic acid molecules that contain genetic information and make up chromosomes
therapeutic cloning -
chromosomes - long molecules in the nucleus of all stem cells; made from DNA
meristems -
call structure
the sub-cellular structure that controls the activites inside is the nucleus
proteins are made on the ribosomes
cell wall/ chloroplast/ permanent vacuole
cell sap is to support the plant
DNA is found in the loops/ in the cytoplasm/ floating free
cell division
there are 46 chromosomes in each human body cell
it is important before mitosis occurs that the cell copies them all (chromosomes)
a stem cell is a non specialised cell
for new cells
transport in and out of cells
perfume diffuses faster
energy from respiration is required for substances to be absorbed against a concentration gradient
features that make exchange surface more efficient is: large surface area/ thin walls/ rich blood supply
