rough ER

ER with ribosomes attached to its surface

hydrophobic

tails of phospholipids that done like water

hydrophilic

water loving heads of phospholipids

cytoskeleton

made of micro tubules and microfilaments to give support to cells

pores

openings in the nuclear membrane

cell theory

idea that all living things are made of cells

lysosomes

digest worn out cell parts and food

existing cells

what new cells for from

cell wall

made of cellulose and surrounds the outside of plant cells

eukaryotes

cells with true nucleus

Golgi complex

system of flattened sacs that modify and package proteins

ATP

energy molecule made inside of mitochondria

fluid mosaic

model of the plasma membrane

integral

proteins embedded in the plasma membrane

cytosol

fluid that makes up cytoplasm

shape

this determines the function of a cell

cilia

short hair like structures made of microtubules that help move cells

plastid

contain pigments in plants

nucleolus

organelle inside the nucleus that makes ribosomes

organ system

made of organs working together to do a similar job such as digestive

peripheral

proteins attached to only one side of the plasma membrane

nucleoid

region in bacteria where their chromosomes is located

cell volume

this grows faster than the surface of a cell forcing them to divide

centrioles

present in animal cells to aid in cell division

ER

system of membranes and tubes connecting the nuclear membrane and plasma membrane

mitochondrion

site of cellular respiration in cells

central vacuole

the largest organelle in plant cells containing the cell sap

ribosomes

made of rRna and protein and where proteins were made

hooke

used a simple light microscope to draw cork from plants

prokaryotes

cells like bacteria without a nucleus or membrane bound organelles

tissue

made of similar cells working together to do a job such as muscle

cytoplasm

all the organelles and fluid between the nucleus and plasma membrane

phospholipids

a double layer of these molecules makes up the plasma membrane

cell

smallest unit of life

organelle

cell structures that perform specific functions for the cell

Leeuwenhoek

first person to see and draw living cells

DNA

genetic material found inside the nucleus of a cell

free ribosomes

unattached ribosomes in the cytosol

flagella

long whip like structures found on some cells to help them move

chromatid

uncoiled chromosomes in the nucleus of non dividing cells

multicellular

organisms made of more than one cell working together

chromosomes

structures in the nucleus made of DNA and proteins

homeostasis

a constant interval environment maintained by cells

nucleus

control center of eukaryotic cells

plasma membrane

surrounds the outside of all cells

archaea

domain containing ancient bacterial forms

vesicles

smalls sacs containing cell products that can be transported in the cell

nuclear envelope

double layer surrounding the nucleus

smooth ER

ER that makes cholesterol and helps detoxify poisons
