QuestionAnswer
Physiology The study of life processes in an organism
Nastic movement A plant's response to a stimulus such that the direction of the response is preprogrammed an not dependent of the direction of the stimulus
Loam A mixture of gravel, sand, silt, clay, and organic matter
Cohesion The phenomenon that occurs when individual molecules are so strongly attracted to each other that they tend to stay together, even when exposed to tension
Translocation The process by which organic substances move through the phloem of a plant
Hormones Chemicals that circulate throughout multicellular organisms, regulating cellular processes by interacting with specifically targeted cells
Phototropism A growth response to light
Gravitropism A growth response to gravity
Thigmotropism A growth response to touch
Perfect flowers Flowers with both stamens and carpels
Imperfect flowers Flowers with either stamens or carpels, but not both
Pollination The transfer of pollen grains from the anther to the carpel in flowering plants
Double fertilization A fertilization process that requires two sperm to fuse with two other cells
Seed An ovule with a protective coating, encasing a mature plant embryo and a nutrient source
Fruit A mature ovary that contains a seed or seeds
water: photosynthesis, turgor pressure, hydrolysis, transport
cohesion-tension theory transpiration causes water to move up the xylem in a plant

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.
