Plasma Membrane

selectively permeable, phospholipid bi-layer, the outer layer of a cell

Nucleus

controls the activities of the cell

Nuclear Envelope

protective layer surrounding the nucleus, selectively permeable

Chromatin

DNA, code for life

Nucleolus

site of ribosome production

Cytoplasm

the fluid in which all organelles are suspended

Endoplasmic Reticulum (ER)

two types: smooth ER processes lipids (fatty acids) for energy; rough ER processes proteins, possesses ribosomes

Ribosomes

site where proteins are made

Golgi Body

collects and secretes protein

Vesicle

packaged protein, formed as a pinched off piece of a Golgi Body

Mitochondria

'power house' of the cell, site of cellular respiration

Chloroplast

only in plant cells, site of photosynthesis, contains chlorophyl, creates glucose

Lysosome

breaks down non-functioning organelles (digestive enzyme)

Peroxisome

only in animal cells, converts H2O2 into H2O + O

Microfilaments

part of the cytoskeleton, they connect the different sides of the cell membrane

Microtubules

radiate from centrioles, comprise the 'cyto-highway'

Centriole

only in animal cells, aid in the process of mitosis

Vacuole

in animal cell, storage site for food, minerals, and waste

Cell Wall

only in plant cells, an extra layer surrounding the cell that provides structure

Central Vacuole

in plant cell, this is huge, because the plant is not motile it is the storage site for everything

Eukaryotic

Cells that have a true nucleus (both animal and plant cells) (ex. non-bacterial cells)

Prokaryotic

Cells that lack a true nucleus (a membrane bound nucleus), these cells have nuclear material floating freely in the cytoplasm (ex. bacterial cells)
