cells part 1
-
diffusion
-
Active transport
The movement os a substance from low concentration to high concentration
This process requires energy

prokaryots and eukaryots
prokaryots
examples
bacteria
They are single organisms. They are very small. They have a cell wall, cell membrane, cytoplasm and plasmoid ( small rings of DNA) They don't have nucleus. They carry out Photosynthesis
prokaryots are small, do not have a nucleus, they do not have organelle
eukaryots
examples

-
protoctist
They are single caled organisms. Some like amoeba live in ponds of water. They have chlorella, chloroplast and are more like plants. Most of them are harmless but some may harm as Plasmodium causing malaria. They have a flangellum( tail) to swim
Eukaryots are bigger, have a nucleus and organelle
virus and pathogens
They produce ilnesses. Viruses are not alive, they infect cells

mitochondria-turn glucose and oxygen to energy
cell membrane-holds the cell together and controls what comes in and out
cytoplasm-where the chemical reactions happens
nucleus- controls what the cell does
ribosome- a small organelle where proteins are made in the cell
cell wall-made of cellulose gives support for the cell
vacuole-contains cell sap, a weak solution of sugar and salts
green chloroplasts- containing chlorophyll for photosynthesis
