LD Animal/Plant Cell

LD Animal/Plant Cells - Biology

TermDefinition
CELL The basic unit of structure and function of all living things.
CELL MEMBRANE A selectively permeable double-layered membrane that covers the cell; separates the cell from its outside environment, recognizes chemicals signals, and maintains homeostasis by controlling which molecules enter and leave the cell.
CELL WALL Nonliving supportive structure found outside cell membrane of plants, algae, and fungi cells; often composed of cellulose. Protects and supports the cell.
CYTOPLASM The watery material between the nucleus and the cell membrane of a cell; contains most of the cell organelles; serves as the site for many of the cell's chemical reactions.
CYTOSKELETON Composed of three types of protein fibers and is found within the cytoplasm.
RIBOSOMES Site of protein synthesis; found loose in cytoplasm or on membranes of endoplasmic reticulum (ER).
ENDOPLASMIC RETICULUM (ER) Cell organelle consisting of membrane-lined channels through the cytoplasm; associated with synthesis, storage, and transport of substances in the cell.
ROUGH ER Ribosomes located along the ER
SMOOTH ER No associated ribosomes. Made of fluid filled channels which allow transport of substances to and from the nucleus to the cell membrane.
MITOCHONDRIA Organelles involved in cellular respiration a process that releases energy for life activities; often called the "powerhouse" of the cell.
CHLOROPLASTS Chlorophyll containing organelle of plants and algae; site of photosynthesis reactions.
VACUOLE A membrane-enclosed, fluid-filled cavity in a cell. Stores water and dissolves minerals.
PLASTID Membrane-enclosed organelles found in the cells of some protists and almost all plants; includes chloroplasts, chromoplasts and leucoplasts.
LYSOSOMES Has enzymes; breaks down worn out cells, food, and bacteria in white blood cells.
GOLGI BODY Processes, packages, and stores products in the cell.
NUCLEUS Cell structure that controls all cellular activities and contains the hereditary material (DNA); usually located in the center of the cell; allows free transfer of that genetic information during the processes of synthesis and reproduction.
NUCLEAR PORES Shallow depressions in the nuclear membrane
NUCLEOPLASM Fluid found in the nucleus
NUCLEOLUS Site of ribosome production, made of DNA, RNA and protein; located within the nucleus.
RNA (ribonucleic acid) The nucleic acid that is transcribed from DNA.
NUCLEAR MEMBRANE Surrounds the nucleus and allows certain materials in and out of the nucleus. Encases the DNA inside the nucleus.
3 THINGS PLANT CELLS HAVE BUT ANIMAL CELLS DO NOT Larger Vacuole, Chloroplasts, and cell wall.
CENTRIOLE Involved in cell division. Only in animals. Semi-permable (only certain things can pass through).

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.
