This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. If the concentration of solutes inside the plant cell is greater than the concentration on the outside - water will _____ the cell?
oxygen
lignin
enter
cortex
2. The best soil for plant growth is ___?

pericarp
rhizomes
eristems
coconut
15. An example of a multiple fruit would be the ___?
transpiration rates decrease
fig
annual ring
there could've been a high concentration of nutrients - such as salt - surounding the roots making it impossible for osmosis to occur
16. Pollen is produced in the ____ of a flower?
upper epidermal cells
axillary buds
anther
superia
17. The spines of cacti are specially adapted to perform 2 imp't functions for the plant - transpiration and photosynthesis. True or false?
antenna pigments
phloem
conduction and absorption
false
18. Differentiate between diffusion and osmosis?
it has the seeds and all 4 parts of a flower would classify it as a fruit instead of a vegetable
If there is a higher concentration of salts outside of the root - then water will not move inside the roots against the concentration gradient. the roots will dehydrate and eventually die
diffusion is the movement of particles from high to low concentration; osmosis is movement of water from high to low concentration
rhizomes
19. When the calyx - corolla and stamen of a flower are attached at the top of the ovary - the ovary is said to be ___?
imbition
inferior
stolon/runner
sclerenchyma
20. The part of the flower in which seeds are produced is the ___?
vascular cambria
region of maturation
ovary
the vascular cambium produces both secondary xylem and secondary phloem - or vascular tissue. The secondary xylem is the wood in dicot plant and lignon surrounds it for support.
