Back 4

Where the specimen is placed

Front 5

Objective lens

Back 5

Magnifies the image

Front 6

Handle/Arm

Back 6

For carrying the microscope

Front 7

Mirror/lamp

Back 7

Directs light up through the stage and specimen

Front 8

Define cells

Back 8

Cells are the building blocks of all livingthings. The cell is the basic structural, functional, and biological unit ofall known living organisms. A cell is the smallest unit of life that canreplicate independently and, cells are often called the building block of life.

Front 9

Define animal cells

Back 9

Cells are the building blocks of all livingthings, including animals. The typical animal cell contains smaller parts knownas organelles. Each organelle has its own specific job to do within the cell.

Front 10

Define a vacuole in an animal cell

Back 10

There may be several small vacuoles in an animal cell.They may contain wastes or chemicals that are being moved around the cell

Front 11

Define Nucleus

Back 11

The control centre of the cell. It controls allchemical reactions in the cell, how the develops and how it reproduces.

Front 12

Cytoplasm

Back 12

A watery, jelly like mixture that contains many smaller parts where the work of the cell takes place.

Front 13

Cell membrane

Back 13

The ’skin’ that holds the cell together. It controls what comes into and leaves the cell.

Front 14

Define plant cells

Back 14

Plants have the same parts as animal cells plus a few extra parts. The vacuole in a plant cell is much larger than in animal cell. The Plant cells contain organelles called chloroplasts.

Front 15

Define vacuole in a Plant cell

Back 15

The vacuole in plant cells is large and occupies mostof the cell. It is filled with sap and stores water, wastes and nutrients. Whenit is full the vacuole pushes against the cell wall and helps keeps the plantrigid.

Front 16

Cell wall

Back 16

Plants do not have a skeleton, so they need somethingelse to keep them upright and to keep their shape. This is the function of thecell wall, which lies outside the cell membrane.

Front 17

Venn diagram of similarities and differences in Animal and plant cells

Back 17

Animal cell: Lysosomes, small vacuoles

Same: Vacuoles, nucleus, ribosomes, ednoplasmic-reticulum, plasma membrane, mitochondria

Plant cell: cell wall, chloroplast, large vacuole

Front 18

Chloroplast

Back 18

Plants make their own food from water and carbondioxide (one of the gases in the air) using energy from the Sun. Photosynthesistales place in chloroplasts, which are found in the green parts of plants

Front 19

Microscope definition

Back 19

A microscope is an optical instrument used for viewing very small objects, such as mineral samples or animal or plant cells, typically magnified several hundred times.

Front 20

Mitochondria

Back 20

The power house of the cell that releases energy from food

Front 21

Lysosomes

Back 21

The garbage disposal units that get rid of wastes from the cell

Front 22

Endoplasmic Reticulum

Back 22

Form pathways that allow materials to move quickly and easily through the cell

Front 23

Ribosomes

Back 23

Microscopic factories that produce the proteins used by the body for growth and repair
