Cells

Cell

• Basic unit of life

• Smallest unit of life

• Come in different shape, size and structures

Plant Cell• Allows substances to move around within the

cell (cytoplasm)

• Contains genetic informations and controls all the activities in the cell (nucleus)

• Controls the movement of substances moving in and out (cell membrane)

• Gives the plant cell its shape (cell wall)

• Traps sunlight to make food for the plant (chloroplasts)

• Contains dissolved sugar in cell sap and stores the sugar (vacuoles)

Animal Cell

• Allows substances to move around within the cell (cytoplasm)

• Contains genetic informations and controls all the activities in the cell (nucleus)

• Controls the movement of substances moving in and out (cell membrane)

• Contains dissolved sugar in cell sap and stores the sugar (vacuoles)

Parts of a Microscope

• The eye looks through the specimen (eyepiece)

• Can be turned to allow the different objectives to be used (nosepiece)

• Can be turned to focus the specimen or raise or lower the stage (big/small adjustment knob)

• Magnify the specimen (objectives)

• The glass slide is placed (stage)

Cell Division

• Cells increases in this process

• New cells are produced to replace dead or damaged cells so that it enables organisms to grow
