summary of cell organelles, endoplasmic reticulum, golgi apparatus, lysosomes, mitochondria, plastids
Answers
Answer:
cell organelles:-The Overview of Organelles. An organelle is a specialized subunit that performs specific functions within a cell. Organelles are embedded within the cytoplasm of eukaryotic and prokaryotic cells. In the more complex eukaryotic cells, organelles are often separately enclosed by their own lipid bilayers.
endoplasmic reticulum:-Endoplasmic reticulum (ER), in biology, a continuous membrane system that forms a series of flattened sacs within the cytoplasm of eukaryotic cells and serves multiple functions, being important particularly in the synthesis, folding, modification, and transport of proteins .
golgi apparatus:-The Golgi apparatus gathers simple molecules and combines them to make molecules that are more complex. It then takes those big molecules, packages them in vesicles, and either stores them for later use or sends them out of the cell. It is also the organelle that builds lysosomes (cell digestion machines).
lysosomes:-Lysosomes are membrane-enclosed organelles that function as the digestive system of animal cells, serving both to degrade materials taken up from outside the cells and to digest the cells' own worn-out components.
mitochondria:-Mitochondria are known as the powerhouses of the cell. They are organelles that act like a digestive system which takes in nutrients, breaks them down, and creates energy rich molecules for the cell. The biochemical processes of the cell are known as cellular respiration.
plastids:-Plastids are the site of manufacture and storage of important chemical compounds used by the cells of autotrophic eukaryotes. They often contain pigments used in photosynthesis, and the types of pigments in a plastid determine the cell's color.
Answer:
Plasma Membrane
The plasma membrane also termed as a Cell Membrane or Cytoplasmic Membrane. It is a selectively permeable membrane of the cell, which is composed of a lipid bilayer and proteins.
The plasma membrane is present both in plant and animal cell, which function as the selectively permeable membrane, by permitting the entry of selective materials in and out of the cell according to the requirement. In an animal cell, the cell membrane functions by providing shape and protects the inner contents of the cell. Based on the structure of the plasma membrane, it is regarded as the fluid mosaic model. According to the fluid mosaic model, the plasma membrane is subcellular structures, made of a lipid bilayer in which the protein molecules are embedded.

Cytoplasm
The cytoplasm is present both in plant and animal cells. They are jelly-like substance, found between the cell membrane and nucleus. They are mainly composed of water, organic and inorganic compounds. The cytoplasm is one of the essential components of the cell, where all the cell organelles are embedded. These cell organelles contain enzymes, mainly responsible for controlling all metabolic activity taking place within the cell and are the site for most of the chemical reactions within a cell.
