Cell Organelles and Function with Labels

Eukaryote cell

Has nucleus, many organelles. examples are: animals and plants; larger than Prokaryote cells

Nucleolus

The organelle where ribosomes are made, synthesized and partially assembled, located in the nucleus

Smooth ER

The site of lipid synthesis and responsible for breaking down toxic substances. (no ribosomes)

Endoplasmic reticulum

a cell structure that transports proteins and other materials from one part of the cell to another.

Cytoplasm

a jellylike fluid inside the cell in which the organelles are allowed to move around freely

Chromosome

a structure in the nucleus that contains hereditary material

Chloroplast

a structure of plant cells that captures energy from sunlight and uses it to produce food; site of photosynthesis

Organelle

a tiny cell structure that carries out a specific function within the cell

Vacuole

an organelle that stores food, water, and other materials needed by the cell; plant- large; animal- many small;

Cell

basic unit of all living things

Mitochondrion

bean shaped organelle that breaks down stored food molecules and then "burns energy" by cellular respiration

Cell membrane

controls what enters and exits the cell; helps hold the cytoplasm and organelles in the cell

Prokaryote cell

lacking a membrane-bounded nucleus and organelles; the cell type also known as bacteria; smaller than Eukaryote cell

Flagella

long, whiplike structures that aid in locomotion and feeding and are less numerous than cilia; present in both prokaryotes and eukaryotes

Nucleus

organelle that controls all the activities of a cell and contains chromosomes; site where mitosis occurs (cell reproduction)

Cilia

short, hair-like structures that enable movement of cells or aid in the movement of other materials; present in both prokaryotes and eukaryotes

Cell wall

strong wall outside a plant cell's cell membrane that protects the cell and maintains its shape; also present in some bacteria

Ribosome

an organelle that is resposible for protein synthesis; Ribosomes together with RNA- make the proteins

Golgi body

receives proteins; sorts, modifies, packages, and distributes them to other parts of the cell or exit the cell.

Rough ER

A network of interconnected membranous sacs covered with ribosomes that make membrane proteins and secrete proteins.

Pili

short projections that help attach prokaryotes to surfaces for reproduction
