cell structures

Cell membrane

Controls what enters and leaves cell

Cell wall

Structure and support, protect cell from damage and pathogens (plants)

Chloroplast

Site of photosynthesis (glucose production). Light into chemical energy

Mitochondria,

produces energy through cellular respiration

Cytoskeleton

Maintains cell shape, enables movement, helps transport materials in cell

Cytoplasm

Jelly fluid where chemical rxn occur. Suspends organelles, allows movement within cell

Golgi apparatus

Modifies, sorts, and packages proteins/lipids into vesicles for transport

Lyosomes

Break down waste, old organelles, and pathogens using enzymes (recycling system)

Nucleus

Stores dna,controls cell activities by regulating gene expression

Nuclear pore

Control movement between nucleus and cytoplasm

Nuclear envelope

Physical barrier between dna in nucleus and the cytoplasm

Nucleolus

Production of rna. Produces and assemble ribosomes

Chromatin

Packages dna mlc into compact dense shape to fit in nucleolus

Chromosomes

Carry hereditary info in the form genes

Ribosomes

Site of protein synthesis. Translates dna to build proteins

Smooth ER

Produces lipids and steroids, detoxifies, stores calcium

Rough ER

Synthesizes, folds, and transports proteins

Vacuoles

Stores water, nutrients, and waste

Vesicles

Store, organize, transport materials throughout cell, related to Golgi apparatus
