What are the two major categories of organelles?
- There are only two main types of cells: prokaryotic and eukaryotic.
- Prokaryotic cells lack a nucleus and other membrane-bound organelles.
What is a type of organelle?
Organelles are small membrane-bound structures found in eukaryotic cells. The types of organelles include those responsible for reproduction, waste disposal, energy production and synthesizing cell substances. The different kinds of organelles float in the cell cytoplasm in numbers that depend on the type of cell.
How many types of organelles are there?
6 Cell Organelles
- Nucleus. nucleus; animal cellA micrograph of animal cells, showing the nucleus (stained dark red) of each cell.
- Ribosomes. Ribosomes are the protein factories of the cell.
- Endoplasmic reticulum.
- Golgi apparatus.
What are the types of organelles and their functions?
Organelles of Eukaryotic Cells
|Nucleus||The “brains” of the cell, the nucleus directs cell activities and contains genetic material called chromosomes made of DNA.|
|Mitochondria||Make energy out of food|
|Golgi Apparatus||Make, process and package proteins|

What are organelles made of?
All the cellular organelles are made of macromolecules like carbohydrates, Lipids, Proteins, and Nucleic acids (DNA, RNA). Atoms – To make macromolecules involves even smaller building blocks. You may have heard of atoms before and their parts: neutrons, protons, and electrons.
