2.1: Cell Structure 

system surrounding a cell

organelle used for cell shape, internal structure, movement and cell division. Made of microfilaments and microtubules.

Cell type with membrane bound nucleus

Cells that have a cell wall, plastids, larger vacuole

used for cell shape, internal structure, movement and cell division

first part of Endomembrane system, DNA → RNA → through Nuclear pores → into Cytosol

Double membrane of 2 lipid bi-layers. Contains proteins that are receptors, transporters & spanners. Restricts access to DNA.

vicious fluid similar to cytosol

Dense, irregularly shaped region, Sub-units of ribosomes are assembled here from proteins and RNA.

DNA & associated proteins in nucleus

system of interacting organelles. Make lipids, enzymes & proteins for secretion/insertion into cell membrane. Sent out through vesicles.

Contains & protects almost all the DNA - separated from cytosol or metabolic processes that may damage it. Makes ribosome units. Membrane bound. Think: Pearl in oyster

RNA in Cytosol translated into Polypeptide chains (by ribosomes), then chains enter

travelers that bud from ER carrying polypeptide chains to Golgi bodies, some go through interior of Rough ER and end up in Smooth ER

proteins (polypep chains) from here are packaged into Vesicles and sent off to Golgi body, some stay to become enzymes that assemble lipids or deactivate toxins

proteins are modified into final form and sorted, new vesicles carry them to plasma membrane or lysosomes

membrane-bound organelle that is involved in photosynthesis and storage in plants and algae

stores pigments other than chlorophyll

stores starch

way of cell to interact with another

double membrane, holds enzymes and pigments for photosynthesis - in stroma

Creates new polypeptide chains and sometimes enhances them into lipids or enzymes. Membrane bound. Extension to nuclear envelope. Repeated, flat folds.

Vesicles fuse and empty here. Put finishing touches on chains like phosphates and sugars to make membrane proteins and then shipped of to plasma membrane or lysosomes. Membrane boud. Stack of pancakes.

Type of vesicle. Marble-like structures. Membrane bound. Transport within the cell or releases them from the cell.

Has its own DNA. Makes ATP. Basically an aerobic bacteria that got comfortable. Membrane bound. Looks like a kidney bean or a small, wrapped baby.

Type of vesicle, containing powerful digestive enzymes. Carry disposals. Recycling centers.

Type of vesicle, contains catalase for fatty or amino acids

Type of vesicle, Vesicle that stores waste and aids in cellular metabolism and water balance. Maintains pressure. Garbage bins.

assemble polypeptide chains, NOT membrane bound, folded ribbon

Makes tubules for cell division, NOT membrane bound, Two pills or logs lying on top of each other

no nuclear membrane, no mitochondria

Subunits of ribosomes are assembled from
