|
cell membrane |
defines the boundary of the cell and controls what enters and leaves the cell |
|
|
nucleus |
carries the genetic material, DNA. Responsible for regulating all activities of the cell |
|
|
nucleolus |
where ribosomes are built from RNA and proteins |
|
|
lysosome |
contain digestive enzymes, breaks down foreign materials |
|
|
smooth ER |
a) production of phospholipids for cell membranes b) synthesis of steroid hormones |
|
|
mitochondrion |
organelle for aerobic respiration, generating ATP, consisting of a matrix and cristae |
|
|
ribosome |
assembles proteins from amino acids in the process of transcription and translation using instructions from the DNA |
|
|
ROUGH ER |
synthesis, folding and modification of proteins. transport of proteins around the cell. consists of ribosomes. |
|
|
golgi body |
where proteins are sorted and packaged into vesicles for delivery to plasma membrane for excretion or to other locations within the cell |
|
|
cytoskeleton |
provides structure for the cell, microtubules and filaments create tracks for organelles to travel around the cell |
|
|
cell wall |
protective barrier that maintains the shape of the cell. - plants - cellulose - bacteria - peptidoglycan - fungi - chitin |
|
|
chloroplast |
site of photosynthesis, containing green pigment chlorophyll which traps light in the light dependent stage |
|
|
cytosol |
fluid contents of the cell |
|
|
cytoplasm |
cytosol + all organelles |
|
|
vacuole |
involved in the storage of wastes and water. Plants have a large vacuole |
|
|
secretory vesicles |
important for cell secretions via exocytosis (exit) and endocytosis (entry) |
|
|
prokaryote |
cells without a nucleus (bacteria, cyanobacteria) |
|
|
eukaryote |
cells with a nucleus (animals, plants, fungi, protista) |
|
|
cellula respiration |
C6H12O6 + 6O2 --> 6H20 + 6CO2 |
|
|
photosynthesis |
6H20 + 6CO2 --> C6H12O6 + 6O2 |
|
|
flagella |
whip like structures on bacteria that enable movement |
|
|
cilia |
extension of cell membrane- called flagella if only 1 or 2 are present |
|
|
fluid mosaic |
- phospholipid bilayer - cholesterol - embedded proteins |
|
|
membrane proteins |
receptor sites, enzymes, cell adhesion, identity marker, protein channels |
