cell organelles

TermDefinition
cytoplasm the material or protoplasm within a living cell,excluding the nucleus. ( jelly like substance)
nucleus control center of the cell. Contains DNA
cell membrane thin, flexible barrier around a cell; regulates what enters and leaves the cell
chromosomes Threadlike structure within a the nucleus containing the genetic info that is passed from one generation of cells to the next
mitochondria powerhouse of the cell, organelle that is the site of ATP ( energy) production
chlorophyll Green pigment in plants that absorbs light energy used to carry out photosynthesis
cytoskeleton Network of protein filaments within some cells that helps the cell maintain its shape and allows movement
ribosomes Responsible for protein synthesis
golgi apparatus Stacks of flat membranous sacs that modify,store, and route products of the endoplasmatic reticulum
cell wall Strong, supporting layer around the cell membrane in some cells
eukaryotes Any cell that does have a nucleus and organelles I.e human cells
prokaryote Any cell that does not have a nucleus or organelles I.e bacterial cells
mictotubules Tubular structures that help the cell maintain structure and movement
centriole Cylindrical structures that help the cell during cell division in animal cells
vacyole spaces in the cytoplasm that store food and water
lysosomes Cell organelle filled with enzymes needed to break down certain materials in the cell
nuclear envelope A double membrane that surrounds the nucleus in the cell
nucleolus The organelle where ribosomes are made, synthesized and partially assembled, located in the nucleus made of RNA and protein.
flagella Long whip like tail used for movement
chromatin Composed of DNA, condenses to form chromosomes
smooth endoplasmic reticulum System of internal membranes within the cytoplasm. Membranes are smooth due to the lack of ribosomes. Functions to produce lipids and some enzymes.
rough endoplasmic reticulum System of internal membranes within the cytoplasm. Membranes are rough due to the presence of ribosomes. Functions in transport of substances such as proteins within the cytoplasm
cilia Small hairs used for movement or transport of materials
phospholipids Molecules that make up cell membrane
chloroplast Structure containing chlorophyll responsible for food production during photosynthesis
Prokayote DNA is circular and floating in the cytoplasm
Eukaryotes DNA is organized in the nucleus in chromosomes
vesicle Small membrane-bound sac that functions in moving products into, out of, and within a cell.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
