What function do organelles perform?

Answer 1

Cell Membrane-

Structure: A thin covering with pores.

Function: Controls what substances come into and out of them; to protect the cell.

Found: Just inside the cell wall(plant cell) Outer boundary(animal cell).

Nucleus- Nickname is " The Brain " of the cell

Structure: Large oval.

Function: Directs all of the cell's activities.

Found: Inside the cell.(usually the middle)

Nuclear Membrane-

Structure: Like the cell membrane a thin covering with pores.

Function: Protect the nucleus, and controls substances that go in and out of the nucleus.

Found: Surrounding the nucleus.

Chromatin-

Structure: Thin thread-like strands.

Function: Contains the information necessary for the cell to function properly.

Found: Inside the nucleus.

Nucleolus-

Structure: Small oval.

Function: Produces ribosomes.

Found: Inside the nucleus.

Cytoplasm-

Structure: Thick gel-like liquid.

Function: To hold the other organelles inside the cell.

Found: Everywhere throughout the cell.

Mitochondria- (Plural- Mitochondrion Nickname " The Powerhouse ")

Structure: Rod-Shaped (Pill shaped ovalish)

Function: Produces energy necessary for the cell to carry out its functions.

* Energy comes from the food we eat (Glucose)

Found: Anywhere inside the cytoplasm.

Ribosomes-

Structure: Small and grain-like

Function: Synthesis proteins.

* Proteins are bodybuilders (to build bone tissue and skin tissue)

Found: In the cytoplasm, and sometimes attached to the endoplasmic reticulum.

Endoplasmic Reticulum-

Structure: A maze of passageways.

Function: To carry materials from one part of the cell to the other.

Found: Throughout the cytoplasm.

* If there are ribosomes on the endoplasmic reticulum, it's a rough endoplasmic reticulum, if there aren't ribosomes on the endoplasmic reticulum it's a smooth endoplasmic reticulum.

Golgi Apparatus- (Also known as the Golgi body)

Structure: A flattened collection of sacs and tubes.

Function: To receiver proteins and other materials from the endoplasmic reticulum and then it packages it and distributes it.

Vacuole-

Structure: A round or ovalish water-filled sac.

Function: To store water.

Found: This is only found in a plant cell and it's found in the cytoplasm.

* Largest organelle in the plant.

Lysosome-

Structure: Small and round.

Function: Breaks down large food parts and old cell parts to be used again.

Found: In the cytoplasm as well. (Only found in an animal cell)

Cell Wall-

Structure: A rigid non-living layer that surrounds only plant cells.

Function: Support and protect the cell.

Found: The outermost edge of plant cells.

Chloroplasts-

Structure: Large, green ovals.

Function: Turn the plant green, absorb sunlight.

Found: In the cytoplasm.

Answer 2

all organelles have a speciffic job, for example the mitochondria creates energy, the Golgi apparatus modifies and ships proteins, and the nucleus controls all activities.there are many other organelles, and you may need to find other examples to their functions.

Answer 3

Generally speaking, organelles means "little organs" and they perform the functions for cells that multicellular organs provide for the body.

A few specific functions:

• Lysosome: immune system - protects the body against invaders and destroys (autolysis) cells that have been damaged internally.
• Nucleus: "brain" of the cell - has the information for the working cell and the blueprint for the cell product.
• Mitochondria: power plant - makes energy and heat from glucose
• Endoplasmic Reticulum - communication system as well as maturation of cell product.

Answer 4

keep the cell alive and functioning
