Cells

Front 1

Isotonic Solutions

Back 1

have an equal amount of solutes and water so the osmotic pressure is equal and there is no movement of water.

Front 2

hypotonic solutions

Back 2

contains less solutes so water will move into a cell to dispense the concentration.

Front 3

hypertonic solutions

Back 3

contains more solutes so water will move to dilute the concentration.

Front 4

filtration

Back 4

Water and material move from an area of higher pressure to an area of lower pressure.

Front 5

cytology

Back 5

the study of cells

Front 6

cell membrane

Back 6

outer boundary of the cells, selectively permeable permits entrance and exit of some materials.

Back 16

tail like projections only on sperm cell provides motility for sperm cell

Front 17

mitosis

Back 17

cell divides for cell growth and maintenance

Front 18

meiosis

Back 18

involves reproduction process of cell division of the sex cells.

Front 19

diffusion

Back 19

involves passive transport no energy is required for this to occur
movement of molecules from one area to a greater concentration
