Cell ORGANELLES. Within most cells these are membrane bound, that is they have a membrane surrounding them and may be composed of membranes. organelles. An envelope with a double membrane which has pores for flow of material, surrounds the chromatin and nucleolus. Nuclear Envelope.

A dark area of chromatin in the nucleus, it is involved in making ribosomes.
Outside the nucleus, inside the cell membrane, the liquid portion (rich in proteins) that allows dissolved molecules to move within the cell.
Cytosol and organelles combined are called the ????. This is where all chemical reactions take place in the cell.
A spherical structure found either free floating in cytosol or attached to RER. These structures are the site of protein synthesis.
A membrane system that may be continuous with the plasma membrane.
A membrane system that has many ribosomes on it. Next to the nucleus and is the site of protein production and packaging.
This has no ribosomes and serves to package the proteins produced in the RER. Proteins are collected within a bubble formed by the membrane.
This is a membrane system located close to the plasma membrane where proteins are modified and leave within a vesicle formed by membranes.
The main site of energy release inside the cell. Many enzymes are located within to help release energy from food molecules. The folded inner membranes assist in ATP production.
These structures are found in cells which produce their own food (plants and autotrophs).
Some examples of plastids are: chloroplasts - chlorophyll.chromoplasts - flowers and fruits.leucoplasts - starch formed from sugars here. What colour are they?
Cell’s storage containers. These are often large in plant cells and contain mostly water. They may also contain food, pigments and salt and help regulate the cell’s rigidity.
These are structures that contain enzymes used to digest old cell structures. In animal cells these may aid in digesting food particles in a food vacuole.
A system of microtubules and proteins that acts like a scaffolding structure within the cell. It can give a cell shape and allow for the passage of organelles.
Common to animal cells, these structures are used during cellular reproduction, pulling the chromosomes to daughter cells during Anaphase and Telophase.
A barrier around the cell that allows only certain molecules in or out of the cell. It is composed of phospholipids with protein molecules embedded within.
