Biology-cells and organisation

animal cells 

size: 10-30 micrometres 

different parts: nucles-controls cell

genes in chromosomes carry protein making instructions

cytoplasm-liquid gel suspending organelles, where chemical reactions take place

cell membrane- controls movement of substances like glucose and mineral ions 

mitochondria- where enrgy's transferred during respiration. 

ribosomes- action site of protein sysnthesis 

plant cells

algae-simple aquatic organisms 

plant cells larger than animal cells

cell wall- made of cellulose for support

chloroplast-contains chlorophyll for photosynthesis 

permanent vacuole- contians cells sap keeps cell rigid so supports plant

eukaryotic

animal,plants,fungi and protista cells count

contains cell membrane, cytoplasm and nucleus 

prokaryotic

 bacteria-single celled livnig organisms 

have cell membrane, cell wall, cytoplasm 

cell wall not made of cellulose 

DNA found in single loop in cytoplasm
