Description

ORGANELLE NUCLEUS

RIBOSOMES

FUNCTION -stores DNA -coordinates cell’s activities

-found in eukaryotic cells

-produces protein

-cell structure

ROUGH -produces protein ENDOPLASMIC RETICULUM SMOOTH - makes cellular products like hormones and lipids ENDOPLSMIC RETICULUM GOLGI APPARATUS - modifies, sorts, and packages proteins for secretion LYSOSOMES

SPECIAL FEATURES

-has ribosome attached to it

-tube-like structure

-composed of flat sacs known as cisternae

-are organelles that contain digestive enzymes. They digest excess or worn-out organelles, food particles, and engulfed viruses or bacteria.

-spherical organelles contained by a single layer membrane -membrane protects the rest of the cell from harsh digestive enzymes contained inside of the lysosome MITOCHONDRIA -produces the energy currency of the cell -acts like the digestive system (ATP) through respiration, and it Takes in nutrients, breaks them regulates cellular metabolism down, and creates energy rich molecules for the cell CYTOSKELETON: -gives the cell its shape and helps -helps keep the cells shape and MICROTUBULES organize the cells parts internal organization -they provide a basis for movement and -helps carry out essential cell division functions like division and movement CYTOSKELETON: -flexible but strong so it can resist -they are the narrowest MICROFILAMENTS crushing and buckling while providing (diameter of about 7nm) support to the cell -made up of two inter twined strands of actin CILIA -moves liquid past the surface of the cell -microscopic hair-like structures FLAGELLA

CENTRIOLES

NUCLEOLUS

- “whip-like” structure that allows a cell -hair like structure that acts as to move an organelle for movement -to help with cell division -helps in the formation of the spindle fibers that separate chromosomes during mitosis -rewrite RNA (rRNA) and combine it with proteins -sends the subunits out to the rest of the cell where they combine into complete ib

-found in pairs and move towards the opposite sides of the nucleus for cell division -isn’t surrounded by a membrane but it sits inside the nucleus
