Vocab cells and cell transport

Prokaryotic

cells without a nucleus

Eukaryotic

Cells with a nucleus

Cytoplasm

Gel like fluid within the cell

Cell membrane

controls what enters and leaves the cell

Cell wall

provides support to all cell types but animals cells

Cytoskeleton

Network tubes that support the cell structure

flagellum

Tail-like structure

Cilia

Short-hair-like structures

nucleus

Cell that contains DNA

Ribosome

site of protein synthesis

ER

transport materials through the cell

Golgi body

where cell products are packaged for export

vacuole

storage of food, water, and waste

Lysosome

Breaks down cell waste

Mitochondria

Where ATP energy is created

Chloroplast

Photosynthesis in plants

Selective permeability

certain materials can pass through

Phospholipid bilayer

double later of lipid

Dynamic Equilibrium

materials move in and out of the cell at the same rate

Passive transport

Movement of materials across the cell membrane without energy

Diffusion

Molecules move through the phospholipid bilayer

Facilitated diffusion

passive movement of molecules through the channel protein

osmosis

movement of water through the cell membrane

Active transport

movement into or out that requires energy

endocytosis

where the cell surround and engulfs material

Exocytosis

where the cell expels materiel in a vesicle

isotonic solution

A solution with the same concentration

Hypotonic solution

A solution that is less concentrated

Hypertonic solution

A solution that is more concentrated
