A Cell is Like a Human Body
Transcript of A Cell is Like a Human Body
Nucleus=Brain/heart Ribosomes Ribosomes are the main protein-makers of the cell. Protein contains amino acids, which are needed for almost all of the cell's functions.
Ribosomes=Bone marrow (creates blood, which is like the amino acids Endoplasmic Reticulum The Endoplasmic Reticulum (ER) has two parts: the smooth ER and the rough ER. The smooth ER takes all of the toxins out of the cell while the rough ER, which has many ribosomes attached to it, both makes molecules for the cell and distributes those molecules.
Smooth ER= Liver
Rough ER= Blood vessels Mitochondria The mitochondria are like little packs of energy in the cell. They combine oxygen with glucose to make energy for metabolism and other cellular functions.
Mitochondria=Insulin-it helps to dissolve sugar and turn it into energy Cell Wall The cell wall provides structure and rigidity for the cell. It also keeps unwanted things out, lets nutrients in and prevents the cell from bursting when too much water enters it.
Cell wall=Skeleton Vacuole The vacuole makes up the majority of the cell and contains all of its water. It also contains other nutrients such as salts, organic acids, pigment and glucose. It helps the plant cell keep its structure and shape.
Vacuole=Blood (it contains most of our moisture and nutrients Cell Membrane The cell membrane is the thin, flexible membrane on the inside of the cell walls. It keeps all of the organelles in one little bag, away from the external environment and anything that might harm it. It lets nutrients in and keeps harmful things out. it gives the cell structure.
Cell membrane=skin. Just pretend that these are lysosomes. Lysosomes are a bunch of enzymes enclosed in a membrane that helps break down the nutrients of the cell into forms that the cell can absorb and use. It also removes waste and bacteria.
Lysosomes=kidneys Chloroplast Chloroplasts are the food makers of the cell. They contain chlorophyll, which obtains sunlight, carbon dioxide and minerals and converts these into glucose and oxygen in a process known as photosynthesis.
Chloroplast=Mouth/stomach Golgi Apparatus The golgi apparatus sorts and packages proteins and other substances in the cell for storage or for distribution to other cells.
Golgi apparatus=Intestines Cytoplasm The cytoplasm makes up the rest of the cell and is a jelly like substance. It provides rigidity and keeps the organells in place.
