Biology Week # 9

Dixon Biology Week # 9

QuestionAnswer
Nucleus The control center of the cell. Contains the genetic information
Evolution Change in a species over time.
Autotrophic an organism that can make its own food by underg0ing photosynthesis
Haploid having one copy of each chromosome( like a sex cell)
Chloroplast organelle that contains photosynthetic pigments . (ex Chlorophyll) Makes sugars for the cell
Mitochondria "Powerhouse" of the cell: where glucose gets broken down for energy by cellular respiration
Phylogeny Evolutionary history of an organism. Can be diagrams using a cladogram
Diploid Having two copies of each chromosome (like a body cell)
Genetic Drift Alteration of allelic frequencies (or how often you see that allele in a population) due to evolution.
RNA The nucleic acid responsible for carrying DNA's message out of the nucleus
Ribosome Organelle Responsible for protein synthesis
Adaptation organisms ability to change due to its environment
heterotrophic an organism that needs to eat other organisms to sustain its energy needs
Allele one of the possibilities of a form of a gene
Convergent Evolution Unrelated organisms becoming more alike due to a shared environment.
Photosynthesis the process of creating sugars using the energy form the sun and Carbon dioxide in the air
Biology The study of life
Cellular Respiration The process of creating ATP by breaking down sugars made in photosynthesis. Occurs in the mitochondria of a cell
divergent evolution related organisms evolving to become less similar
genetics the study of inheritance
cell wall resent in a plant cell, not an animal cell: provides the cell with a rigid structure
abiogenesis "without life's origin"
gamete a reproductive cell (sperm or egg)
gradualism evolution that occurs slowly over a long period of time.

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.
