Also called the plasma membrane gives mechanical strength to the cell.
Its unique structure enables itself to serve as molecular traffic regulator.
It is 5 up to 10 um in thickness. It also exhibits fluid mosaic nature, seal itsef if broken.
B. THE CYTOPLASM AND ITS ORGANELLES
A mass of jelly-like material that is somewhat grayish or colorless, translucent and viscous
It can change from semi solid to semi liquid.
C. CELL ORGANELLES
(ER) is the transport network for molecules targeted for certain modifications and specific destinations, as compared to molecules that will float freely in the cytoplasm.
ER has two forms: the rough ER and the smooth ER.
The ribosome is a large complex composed of many molecules, including RNAs and proteins, and is responsible for processing the genetic instructions carried by an mRNA.
Ribosomes float freely in the cytoplasm or sometimes bind to another organelle called the endoplasmic reticulum
are self-replicating organelles that occur in various numbers, shapes, and sizes in the cytoplasm of all eukaryotic cells.
Mitochondria have two functionally distinct membrane systems separated by a space: the outer membrane, which surrounds the whole organelle; and the inner membrane, which is thrown into folds or shelves that project inward. These inward folds are called cristae.
Mitochondria play a critical role in generating energy in the eukaryotic cell, and this process involves a number of complex pathways
GOLGI BODIES OR GOLGI APPARATUS
(also called the golgi apparatus or golgi complex) a flattened, layered, sac-like organelle that looks like a stack of pancakes and is located near the nucleus. The golgi body packages proteins and carbohydrates into membrane-bound vesicles for “export” from the cell.
are often referred to as the garbage disposal system of a cell.
digest foreign bacteria that invade a cell.
helping to recycle receptor proteins and other membrane components and degrading worn out organelles such as mitochondria. Lysosomes can even help repair damage to the plasma membrane by serving as a membrane patch, sealing the wound.
Variety of organelles similar to lysosome but contains different enzymes. One of these is the glyxoxysomes present in some plant, another is peroxisomes which contain powerful oxidative enzymes.
Microtubules that provide support to the internal system of cell thus, it provides support and shape.
Also provides pathways for certain cellular molecules to move.
Membrane- bound, fluid- filled spaces found in both animal and plant cell but bigger in plant cell.
