Chloroplast
• A structure in the cells of plants and some other organisms that captures energy from sunlight and uses it to produce food.

Chlorophyll
• Chlorophyll is a green pigment found in cyanobacteria and the chloroplasts of algae and plants.

Cell Wall
• A rigid structure that surrounds the cells of plants and most bacteria

Plasma Membrane
• thin, flexible barrier around a cell; regulates what enters and leaves the cell

Microfilaments/Microtubules• Microfilaments or actin
filaments are the thinnest filaments of the cytoskeleton, a structure found in the cytoplasm of eukaryotic cells.
• Microtubules are a component of the cytoskeleton, found throughout the cytoplasm. These tubular polymers of tubulin can grow as long as 25 micrometres

Golgi Apparatus
• receives proteins and other newly formed materials from the ER, packages them, and distributes them to other parts of the cell or to the outside of the cell

Endoplasmic Reticulum
• network of membranes within a cell's cytoplasm that produces a variety of substances
![Page 18: Prokaryote The prokaryotes are a group of organisms whose cells lack a cell nucleus](https://reader036.vdocuments.net/reader036/viewer/2022062314/56649e855503460f94b8744d/html5/thumbnails/18.jpg)
Chromatin
• contains information for directing a cell's activities

Centrioles
• A centriole is a cylinder shaped cell structure found in most eukaryotic cells, though it is absent in higher plants and most fungi.
