What is a stain? | A substance used to make cell structures more clearly visable. |
Light microscope | a microscope that uses light |
Compound microscope | a microscope that uses multiple lenses |
Function of nucleus | contains cell chromosomes which are made of DNA, these hold the genetic information which controls cell activity |
Function of mitochondria | site of aerobic respiration, mitochondria are found in greater abundance in cells with high energy demands such as muscle cells
involved in respiration to release energy in both animal and plant cells |
Function of cell membrane | consists of phospholipid and protein molecules, selectively permeable, controls the entry and exit of materials in and out of the cell. |
Function of ribosome | site of protein synthesis, found in the cytoplasm or attatched to tubular structures in the cell |
Function of chloroplast | site of photosynthesis, contain green pigment chlorophyll which absorbs light energy |
Function of cell wall | gives support to the cell and structure to plant tissue, made of a carbohydrate called cellulose |
Function of cytoplasm | jelly like material, chemical reactions happen, contains organelles |
Function of vacuole | contains cell sap which is a solution of salts and sugars, important in maintaining the shape of the cell |
organelles | small sub-cellular structures with a special function |
Can you see mitochondria and ribosomes with a light microscope? | no, they are too small |
differences of a fungal cell | only difference from an animal cell is the presence of a cell wall, this cell wall is not made from cellulose |
differences of a bacterial cell | no nucleus, has DNA and circular plasmids, the cell wall is different to plants |
