Cell Bio
Animal(eukaryotic cells)
Plant(eukaryotic cells)
Bacterium(prokaryotic cells)
Vacuole- carry cell sap
Cytoplasm- contains enzymes and is base of all reactions
chloroplasts- perform protein synthesis
mitrocndria- perform resperation
Cell membrane- controle what enters and leaves cell
ribersons- perform protein sythesis
Cell wall- supply's stucture
Neclus- contains genetic info
mitochondria- performs resperations
ribersons- perform protein synthesis
Nucleus- contains genetic infomation
cell membrane- controles what enters and leaves the cell
cytoplasm- contains enzymes and is base of all reactions
Cytoplasm- where all reaction happen and filled with enzymes
Plasmid- contains genetic infomation
Cell membrane- contoles what enters and leaves cell
Flagellum- helps bactira move
Cell wall- supply's structure for cell
chromosomal Nucleus - contains genetic information
Magnification
this helps us see things that we can't with the naked eye
cell differentiation- this is when a stem cell turns its self into specialized cells as it developed in the womb
Equation-magnification=image size/ real size
Specialized cells
muscle cell lots of mitrocondra to react fast
hair root cell-large surface area to obsorb minirals and water
nerve cell long to carry signal over distance
phloem and xylem cell-long tubes to help water travil futer
Sperm cell- have long tail to swim and lots of mitrocondia
Chromosomes and mitosis
Chromosomes are genetic infomation you have 46 of them in 23 pairs they are organized into a doublke helix structure and you get 23 from each parent
Mitosis is the reproduction of cells in the body
growth and DNA repoduction
1)the cells DNA spreads into long strings
2)Cells grow and increase amound of DNA
3)It the duplicates the DNA in the cells
Mitosis
4) the chromosones line up
5) the cell membrain devides
6)cell membrain and cytoplasm split
transport- the larger the suface the higher the rate of transport
Stem cells are able to cure desieses due to being able to replace cells, howver enbros have to be killed, as a result there are ethical issues
Osmosis this is when water goes from a high to low contration over a membrain
Active transport- this is the movement of particals against the contration gradiant over a pataily permable mebrain requireing energy
Diffution- this is when particals go from high to low contration over a membrain
