Cell Structure and the cell membrane summary

All living organisms are made of _____ ; therefore cells are the basic _____ of life.

Stains e.g. ________ __________ are used to show the parts of animal and plant cells more __________.

_____________ are the structures found inside a cell.

MOST animal and plant cells have the following parts:

__________ controls all cell activities as it contains DNA which codes for all the proteins a cell makes

_________________ where all the chemical reactions of the cell take place either directly in it or in

organelles suspended in it.

______ _____________ is the layer around the cytoplasm and controls what molecules can get into or out

of the cell and is selectively permeable.

The following organelles are not found in all cells.

______ ______ is the layer made of mainly cellulose that is around the cell membrane in

some cells, it gives support, prevents bursting and is fully permeable.

__________ is a bag like organelle, which can be filled with cell sap or other molecules depending on the

cell. It controls water content of the cell.

________________ are the organelles where the reactions for photosynthesis occur.

_____________________ are the organelles where the reactions for aerobic respiration occur.

_______________ are the organelles that are the site of protein synthesis.

_______________ rings of genetic information that can be used for genetic engineering.

of all cells is ______________ permeable.

It consists of a ___________________ bilayer and

protein molecules whose arrangement is described as

the ________ _________ model.
