Biology 221 Lab #5

roots and stems

QuestionAnswer
periderm contains cork cambium and cork; 2 or more cells thick
epidermis covers stem and roots
root hairs in all roots
phloem carries minerals up to leaves; transports products of photosynthesis to roots
phloem rays made of parenchyma; fills in phloem
pericycle protect the xylem and phloem; strengthen the roots
endodermis regulates the amount of water transport through the plant
cortex tissue between epidermis and vascular tissues
parenchyma generalized/storage; blue thin cell walls
xylem transport water up through plant
collenchyma structure/support
apical meristem responsible for primary growth; mitotic division
sclerenchyma structure/support; red thick walls
stele (vascular cylinder) contains xylem, phloem, and pith (in monocot)
vascular cambium secondary growth occurs and pushes phloem out while packing xylem on inside
cork cambium pushes cork out and cortex (parenchyma) inside
pith contains all parenchym.. usually inner-most structure
bark contains cork, cork cambium, cortex, and phloem
air spaces in dicot leaves and monocot stems
ground tissue in monocot stems
4 fundamental tissues parenchyma, collenchyma, sclerenchyma, and endodermis
apical meristem grow in length, primary growth
lateral meristem grow in girth; secondary growth
2 tissues that make up surfaces epidermis and periderm
epidermis one cell layer thick
tissues aggregations of cells modified to perform a specific group function
waxy cuticle prevent water from escaping
guard cells let air (CO2) into the photosynthetic cells
spongy mesophyll (parenchyma) contains spaces to allow for passages of gases
palisade mesophyll (parenchyma) contains chloroplasts; closely packed, elongated parenchyma
stomata opening between the guard cells
chlorenchyma spongy and palisade parenchyma
midrib large vein in leaves (extension of petiole in dicots

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.
