What is the largest Organelle?
The Nucleus
1 of 16
What does the nucleus make?
RNA and ribosomes
2 of 16
What is the function of rough ER?
transports proteins that were made on the attached ribosomes, some of which may have been secreted by the cell surface membra
3 of 16
What is the function of smooth ER?
involved in the production of lipids that the cell needs
4 of 16
What is the structure of Golgi apparatus?
stack of membrane-bound, flattened sacs
5 of 16
What does the Golgi apparatus do?
modifies and continues the production of proteins made by the ER, it also helps with the transportation of lipids around the cell
6 of 16
Function of Mitochondria?
produces ATP during photosynthesis
7 of 16
Function of chloroplasts?
The site of photosynthesis in plant cells
8 of 16
What is the role of Lysosomes?
They break down materials, as they contain powerful digestive enzymes
9 of 16
Structure of lysosomes?
spherical sacs surrounded by a single membrane
10 of 16
Why are ribosomes and centrioles different to other organelles?
They are not membrane bound
11 of 16
Where are ribosomes located?
some are free in the cytoplasm and some are bound to ER
12 of 16
What do ribosomes consist of?
2 subunits
13 of 16
Function of ribosomes?
site of protein synthesis in the cell
14 of 16
What are centrioles?
they are small tubes of protein fibrers, they take part in the division of cells where they form spindles which move chromosomes during nuclear division
15 of 16
Where are centrioles found?
there is a pair next to the nucleus in an animal cell, and they are found in the cells of some protocists
