Biology 1300 Exam 3 questions with answers |\ |\ |\ |\ |\ |\
Vascular Plants Definition - CORRECT ANSWERS ✔✔Roots (organs)
|\ |\ |\ |\ |\ |\ |\
below ground, stem and leaves above ground.
|\ |\ |\ |\ |\ |\ |\
What are the function of roots? - CORRECT ANSWERS
|\ |\ |\ |\ |\ |\ |\ |\ |\
✔✔Anchoring, absorbing nutrients and water |\ |\ |\ |\
What are the functions of the four parts of a root? - CORRECT
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
ANSWERS ✔✔A: Taproot- Enters the ground straight down, can
|\ |\ |\ |\ |\ |\ |\ |\ |\
store carbs (tuberous roots), find moisture.
|\ |\ |\ |\ |\
B: Lateral root- Grows away from the taproot, straight up.
|\ |\ |\ |\ |\ |\ |\ |\ |\
C: Root hairs- Increase surface area to increase nutrient and
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
water absorption. |\
D: Fibrous roots- Found in monocots (grasses)
|\ |\ |\ |\ |\ |\
Stem function - CORRECT ANSWERS ✔✔Support, store nutrients,
|\ |\ |\ |\ |\ |\ |\ |\
generate new tissue, tuber stores carbs (potatoes), tip of the
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
stem is called the Apical Bud
|\ |\ |\ |\ |\
Leaf function - CORRECT ANSWERS ✔✔Produced at nodes, site of
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
photosynthesis in chloroplasts, simple=1 leaf, complex=2 leaves |\ |\ |\ |\ |\ |\
Dermal plant tissue - CORRECT ANSWERS ✔✔Protective covering
|\ |\ |\ |\ |\ |\ |\ |\
for roots, stems, leaves; regulates what goes in and out of a cell
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
(stomata)
, Ground plant tissue - CORRECT ANSWERS ✔✔Majority of the
|\ |\ |\ |\ |\ |\ |\ |\ |\
plant body, made of parenchyma/collenchyma/sclerenchyma
|\ |\ |\ |\ |\
cells, storage and support, responsible for most metabolic
|\ |\ |\ |\ |\ |\ |\ |\
processes.
Vascular plant tissue - CORRECT ANSWERS ✔✔Transport food,
|\ |\ |\ |\ |\ |\ |\ |\
water, hormones, minerals, can help with support
|\ |\ |\ |\ |\ |\
Parenchyma tissue - CORRECT ANSWERS ✔✔Metabolism, |\ |\ |\ |\ |\ |\
photosynthesis, storage, regeneration; thin cell walls |\ |\ |\ |\ |\
Collenchyma tissue - CORRECT ANSWERS ✔✔Support and |\ |\ |\ |\ |\ |\ |\
flexibility of growing stems and leaves; uneven thickening of cell
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\
walls, thickened with pectin and cellulose
|\ |\ |\ |\ |\
Sclerenchyma tissue - CORRECT ANSWERS ✔✔Structural support |\ |\ |\ |\ |\ |\ |\
and protection, most cells are dead, form outer covering of nuts
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
and seeds; evenly thick cell wall, thickened with lignin
|\ |\ |\ |\ |\ |\ |\ |\
Xylem - CORRECT ANSWERS ✔✔Transport water and minerals
|\ |\ |\ |\ |\ |\ |\ |\
from roots-->shoots (bottom to top), long thin tube for water to
|\ |\ |\ |\ |\ |\ |\ |\ |\ |\ |\
pass
Phloem - CORRECT ANSWERS ✔✔Transports sugar to all plant
|\ |\ |\ |\ |\ |\ |\ |\ |\
parts; goes to roots during winter (top to bottom)
|\ |\ |\ |\ |\ |\ |\ |\
