Proteins are absorbed, modified, packaged and distributed to their destination in this organelle.
Although not membrane bound, this organelle is the site of protein synthesis.
The "Powerhouse" of the cell, this organelle is the site of cellular respiration and production of ATP.
The "skeleton" and "muscles" of the cell, this structure is made of microtubules that also form cilia, flagella and centrioles.
This organelle is green due to the presence of chlorophyll and is the site of photosynthesis.
This set of smooth membranes functions to synthesize lipids and detoxify drugs and toxins.
This membrane holds the chromosomes within the nucleus.
This organelle is very large in plant cells and contains food, enzymes, minerals, wastes and water.
This, the largest object in a eukaryotic cell, holds the cell's genetic information.
Everything between the cell membrane and the nucleus. Contains all organelles and cytosol (solution in the cell).
Composed of cellulose, this gives plant cells stability.
This selectively permeable structure is composed of phospholipids embedded with proteins.
This extensive network of membranes is studded with ribosomes and functions as a surface for protein synthesis and transport of materials.
This specialized vesicle contains digestive enzymes and is the site of hydrolysis in animal cells
These small microtubules are involved in animal cell division.
Dark sections of DNA and proteins in the nucleus which are the site of ribosome synthesis.
Structures within the nucleus that are composed of DNA. Called chromatin in a non-dividing cell.
support structure (plants, bacteria & fungi)
site of ribosome synthesis
detoxification/ lipid synthesis
protein package and distribution center
surface for protein synthesis and transport
internal support, cilia and flagella
Large, Central Vacuole
water and solute compartment in plant cells
site of protein synthesis
used in animal cell division only
Outermost part of cell. Can easily be confused with the cell wall (see below).
If the cell is labeled plant, bacteria or fungi, look for a cell wall on the outside of the cell
membrane. Sometimes drawn as mesh or fiber-like material.
Usually easy to locate, the largest structure in the cell. Normally oval or round in shape.
It usually has a line to the center of the circular body.
The membrane around the nucleus. Usually with obvious nuclear pores or holes.
Can be confused with the nucleus so look for labels that might apply to each part.
Usually in the form of chromatin, a spaghetti like group of DNA strands.
Occasionally the chromosomes are shown as X-shaped structures within the nucleus.
Dark area(s) (nucleoli) within the nucleus. It is part of the DNA and will be mixed in with the
chromatin. Each nucleus will have one to three nucleoli drawn in.
Usually peanut or jelly bean shaped with a squiggle or worm shape within.
May be confused with the chloroplast in a plant cell.
Usually has oval to mound shape. Membranes inside are usually stacked like papers.
Membranes normally located just outside the nucleus and dotted with obvious ribosomes.
Represented as small, free floating dots in the cytoplasm or attached to the outside of the rough ER.
Similar to rough ER, usually further away from the nucleus than the ER, never with dots.
Shown further away from the nucleus than the ER, looks like stacks of pita bread with small dots (vesicles) to each side.
Easily identified as a large, central, fluid filled space in a plant cell. Food vacuoles are much
smaller. Contractile vacuoles are star-shaped.
Small, fluid filled organelles in animal cells. Easily confused with the lysosome in an animal cell.
Found in animal cells. They are easily confused with vesicles but sometimes with various
internal features such as small food particles.
Always shown as a pair, next to the nucleus, and only in animal cells. Look like little,
cylindrical stacks of tubes. Sometimes shown in cross section as a swirl of lines or commas.
Usually labeled with a line pointing to the inside of a cell but not to any particular structure.
