Human Cell Structure

Front 1

Extracellular fluid

Back 1

The fluid outside of the cell

Front 2

Erythrocytes

Back 2

Red blood cells; carry oxygen

Front 3

Rough ER

Back 3

Network of tubes and membranes that is connected to the nuclear membrane. Bumpy, covered in ribosomes(factories for making protein), primarily involved in protein production

Front 4

Cell membrane

Back 4

Form’s a cell’s outer border

Front 5

Phospholipids

Back 5

Has one head and two tails, head likes water and tails don’t. Two layers of phospholipids make up the plasma membrane.

Front 6

Intracellular fluid

Back 6

Fluid inside of the cell

Front 7

Golgi complex

Back 7

A collection of small flattened sacs that stack on one another, helps transport cell products where needed with vesicles.

Front 8

Lysosomes

Back 8

Small vesicles containing enzymes that can digest many kinds of molecules and debris

“Stomach”

Front 9

Nuclear membrane

Back 9

Outer part of the nucleus that is connected to the rough ER

RNA must pass through it to the cytoplasm

Front 10

Organelles

Back 10

“workstations”

Front 11

Centrioles

Back 11

Helps with cell division

Front 12

Cytosol

Back 12

The liquid found inside the cell

It plus the organelles make up the cytoplasm

Front 13

Anatomy

Back 13

The study of the body’s parts and how they are put together

Front 14

Cell

Back 14

The building blocks of life

Front 15

Physiology

Back 15

The study of how the parts of the body function, how everything works

Front 16

Ribosomes

Back 16

Make proteins; found floating in cytoplasm and attached to rough ER ; read protein-building instructions from messenger RNA (made in the nucleus) which is a copy of the instructions (genes) found in nucleus to string together amino acids and form proteins

Front 17

Vesicle

Back 17

Organelles, that transport and store substances within a cell and to others

Front 18

Smooth ER

Back 18

Tube like in appearance and is not covered with ribsomes. More involved with the production of fats, certain hormones, and break down of certain hormones, and break down of some toxins that enter the cell

Front 19

Mitosis

Back 19

Cell division

Front 20

Secretory vesicle

Back 20

Tiny packages in which certain cell secretions can be transported (packaged in the Golgi apparatus)

Front 21

Mitochondria

Back 21

The powerhouse of the cell; generate and store energy by producing high-energy molecules that act as batteries such as ATP using glucose

Front 22

Cytoskeleton

Back 22

Network of tubes/filaments throughout cell that provide support for organelles

Front 23

Nucleus

Back 23

Directs the action of the cell’ control center

Front 24

DNA

Back 24

(Deoxyribonucleic acid) a big molecule made up of 2 long strings of smaller molecules called nucleotides
