What is the function of the following organelles?
Nucleus, mitochondria, chloroplast, lysosomes, vacuoles, ribosomes, ER
Golgi apparatus, cilia, flagella, cell membrane, nuclear membrane, cell wall, cytoplasm
Mitochondria:The powerhouse of the cell .They take in nutrients, and breaks them down and creates energy for the cell.
Chloroplast: to convert energy from the sun into sugars for the cell.
Lysosomes:they digest waste or worn out organelles
Vacuoles: the main function of vacuoles is to separate anything that can be harmful to the cell.
Ribosomes: synthesize proteins for use through out the cell.
ER: creates and folds proteins and then carries these synthesized substances to the Golgi apparatus.
Golgi apparatus: identifying, processing and packaging macromolecules. Cell membrane: to protect the cell from its environment by controlling the movement of substances in and out of cells.
Nuclear membrane: to separate the nucleus of a cell from the cytoplasm around it.
The cell organelles and their major functions are given as follows:
Organelles are the structure that are present in or on the cell, that regulate specific type of functions that are essential for the life and survival of the cell or organisms.
Nucleus -
the control centre of the cellular activities
is the storehouse of the cell’s DNA, hereditary unit
monitor cellular activities including metabolism and growth
Mitochondria -
Release of energy form pyruvic acid produced in the cytoplasm in the form of ATP
helps in the Synthesis of respiratory enzymes.
Chloroplast -
responsible for trapping light energy for photosynthesis
site of photosynthesis
Lysosomes -
Intracellular digestion and destroys foreign substances.
rapidly destroy organelles
Vacuoles -
Storage of water and other substances,food pigments and waste products.
Gives turgidity to the plant cell by pressing against a cell wall.
Ribosomes - main function is Protein synthesis.
ER -
transport system of the cell
protein manufacture
production of lipids, steroids
responsible for detoxifying the cell.
Golgi apparatus -
Synthesis and secretion of enzymes, hormones
The formation of acrosome.
Cilia -
move the cell or the extracellular fluid
Flagella -
responsible for the cell movements
Cell membrane -
It separates the content of the cell from its surroundings.
It regulates the entry/exit of certain solids and ions into the cell.
It maintains the shape of the cell that is the animal cell.
Nuclear membrane -
Release of energy form pyruvic acid produced in the cytoplasm in the form of ATP
helps in the Synthesis of respiratory enzymes.
Cell wall -
provides tensile strength and protection against mechanical and osmotic stress.
Cytoplasm -
Different organelle is contained in it perform different functions.
