CELLULAR ORGANELLES Flashcards
structure in cells that performs specific functions
Cellular Organelles
3 Major Parts of Cells
Cell Membrane, Cytoplasm, and Nucleus (DNA)
controls what molecules are allowed in and out of the cell
Cell Membrane
what is the component of Cell Membrane
Phospholipid Bilayer (made up of diff nutrients, enzymes, proteins)
2 Parts of Phospholipid Bilayer
Phosphate head and Lipid Tail
Phosphate Head
Polar; hydrophilic head (water-loving)
Lipid Tail
non-polar; hydrophobic tail (water fearing); helps in the in and out the transfer of materials
transport ions in and out of the cell
Protein Complex
other major part of the also known as cytosolJelly like matrix which house all the structural organelles of the cell - composed of water, enzymes, nutrients, and gases
Cytoplasm
Hyaloplasm
the fluid part which does not occupy any structural organelles
houses of the following groups of organelles according to function
a. Cell Manufacturer, b. Energy Processing, c. Breakdown of Materials, d. Support and Movement
“build protein”
- responsible for protein synthesis and is present in all types of cells - smallest organelles in all cells
Ribosomes
A type of ribosome which found in cytoplasm
free
a type of ribosome found in the endoplasmic reticulum
attached/bound
2 Major Parts of Ribosome
Large subunit and Small subunit
it is the copy of genetic information from DNA
RNA
large folded membrane system with attached ribosomes
Rough Endoplasmic Reticulum
Large, folded membrane system without ribosomes
Smooth Endoplasmic Reticulum
Differentiate RER AND SER
reduction of protein
lipid synthesis
- packaging center of the cells
- receives product from the endoplasmic reticulum and adds a final modification
- it also sorts these products and sends them to their final destination
Golgi Apparatus
CIS-FACE
(ENTRANCE) -attached to the Golgi Apparatus and will wait to mature the product and move it to the exit
TRANS-FACE
(EXIT) matured macromolecule
-detached; Golgi vesicle intracellular transport; secretory vesicle; exocytosis
It is an organelle in Energy Processing
a powerhouse of the cell
-both plants and animals
Mitochondria
converts ______ into _______
converts glucose into ATP-Adenosine triphosphate (energy molecule)
folded inner partitions inside the mitochondrion
Cristae
(breaking down of glucose to extract ATP molecule)
Cellular Respiration
- only presents in the plant cells (plastids)
Chloroplast
Use the energy from the _____ to form ______ from
______ and ______
PHOTOSYNTHESIS
Use the energy from the sunlight to form glucose molecules from
C02 and H2O
Thylakoid and Stroma
An organelle functions in breakdown of materials
also called as Suicide bag/ defender of the cell
Lysosome
It has a digestive enzyme which
highly acidic
food molecules or bacteria that can enter the cell
Phagocites
Vesicle formed from ER containing oxidative and other enzymes
- Aids in detoxification
- Engulfing free radicals to detoxify the cell
Peroxisome
Storage of food, water, waste, etc.
A membrane-enclosed sack that can be filled with anything
Vacuole
Organelle use to maintain turgor pressure in plants
Vacuole
fluid in the vacuole
CELL SAP
membrane of vacuole
TONOPLAST
tiny vacuole
FOOD VACUOLE
has paramecium, pumps out excess water from the cell
CONTRACTILE VACUOLE
It is an organelle in Support & Movement -provides structural support; movement of materials; in some species movement of whole cells
Cytoskeleton
(biggest) hollow structure formed protein subunits;
Microtubules
Groups of centrioles
Centrosome
add structural integrity inside eukaryotic cells, smaller than microtubules larger than microfilaments
Intermediate Filaments
small fibril formed from protein subunits
- aids in the structure of animal cells
Microfilaments (actin filaments)
cytoplasmic projection found in animal cells responsible for movement
Cilia
same with cilia but has longer whip-like structures
Flagella
special extensions in bacterial cells made for conjugation
For attachment and conjugation where donor bacterium and acceptor bacterium. Donor bacterium donates genetic information to acceptor bacterium
Pili
Some species of bacteria have this protective third covering
Capsule
composition of capsule
Polysaccharides
