Organelles

Biology

QuestionAnswer
Organelles. Specialized structures in a cell that carry out functions.
Semi-permeable (allows certain things in and out of the cell), helps maintain homeostasis. Cell/Plasma membrane.
Granular, fluid-like material, all organelles are suspended in it. Cytoplasm.
Contains DNA, controls the cells' metabolism and reproduction. Nucleus.
Selectively permeable double structure that surrounds the nucleus, has pores. Nuclear membrane.
Structure within the nucleus that is involved in the synthesis of the RNA, produces ribosomes. Nucleolus.
Intercellular transport. Endoplasmic Reticulum.
Cite of protein synthesis. Ribosomes.
Releases energy for the cell, site of aerobic respiration, ATP is made here. Mitochondria.
. (Post office/shipping center), shipping, packaging, processing, exporting. Golgi Body/Complex/Apparatus
Contain digestive enzymes, break down worn out cell organelles, kills bacteria. Lysosome.
Stores food and wastes. Vacuoles.
Cell division, animal cells only. Centrioles.
Only in plant cells, gives the cell its shape, outside of the cell membrane. Cell wall.
Found only in plant cells, contain the pigment chlorophyll, sites of photosynthesis. Chloroplasts.
Gives the cell its shape, involved in the movement of chromosomes during cell division. Microtubules.
. Long, solid, thread-like, involved in cell division. Microfilaments
Tiny beating hairs for locomotion. (Ex:Paramecium) Cilia.
Long whip-like tail involved in locomotion. (Ex: Sperm cell) Flagella.
Three parts of the cell theory. 1. Cells are the structural unit of living things. 2. Cells are the functional unit of living things. 3. Cells come only from pre-existing cells.
Exceptions to the cell theory. 1. Viruses are not made up of cells. 2. Mitochondria and chloroplasts have their own DNA and can duplicate themselves. 3. The first cells must have arisen from non-cellular structures.
Discovered one-celled organisms and sperm cells. Anton Van Leeuwenhoek.
Examined slices of cork and other plant materials with the compound microscope, named the cell. Robert Hooke.
Discovered the nucleus. Robert Brown.
Stated that all plants were composed of cells. Mathhias Schleiden.
Stated that animal tissues were also composed of cells. Theodor Schwann.
Stated that all cells arise from pre-existing cells. Rudolph Virchow.

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.
