Bio 1500 UPDATED ACTUAL Exam
Questions and CORRECT Answers
Morphogensis - CORRECT ANSWER - the development of the form of an organism and
its structures. This stage begins differentiating organs.
Protoderm will become the - CORRECT ANSWER - epidermis which will protect the
plant
ground meristem will become - CORRECT ANSWER - ground tissue that stores food and
water called chlorenchyma
procambium will become - CORRECT ANSWER - the vascular tissue Xylem and Phloem.
Xylem moves water upwards and phloem moves products of photosynthesis downward
Cotyledons - CORRECT ANSWER - not true leaves made from embryonic cells.
Monocots have one dicots and eudicots have two.
The carpel is - CORRECT ANSWER - The female part of the plant which consists of the
ovule, ovary, stigma, and style. ONLY PART THAT REMAINS>
Parenchyma - CORRECT ANSWER - ground tissue- Involves the support, storage,
synthesis, secretion, wound repair
Collenchyma - CORRECT ANSWER - type of ground tissue cell with a strong, flexible
cell wall; helps support larger plants
Sclerenchyma - CORRECT ANSWER - type of ground-tissue cell with an extremely thick,
rigid cell wall that makes ground tissue tough and strong
, Germination - CORRECT ANSWER - the process whereby seeds or spores sprout and
begin to grow. At this point the cell is at 2n sphorophyte and is diploid. Cotyledons are formed
first without leaves being grown.
Xylem - CORRECT ANSWER - vascular tissue that carries water upward from the roots
to every part of a plant
Phloem - CORRECT ANSWER - Living vascular tissue that carries sugar and organic
substances throughout a plant (products of photosynethis)
vessels - CORRECT ANSWER - thick tubes that carry water (dead at maturity)
dry indehiscent fruits - CORRECT ANSWER - The pericarp will not split open but move
along with the seeds during dispersal. (Sunflower seeds) Don't split when mature.
dry dehiscent fruits - CORRECT ANSWER - The pericarp will split open to release the
seeds for dispersal. (peas)
simple fleshy fruits - CORRECT ANSWER - develop from flower with single pistil.
Tomato, berry. Can have multiple seeds buried within the flesh of the fruit.
compound fruit - CORRECT ANSWER - fruit comprised of multiple pistils, either from
individual flowers with multiple pistils (aggregate fruit) or fused pistils from multiple flowers
(multiple fruit). (strawberries, raspberries)
double fertilization in angiosperms - CORRECT ANSWER - one sperm fertilizes the egg
to form a zygote and one sperm combines with two polar nuclei to form the endosperm 2n and
3n. The zygote becomes the egg while the 3n is the endosperm supporting the plant.
angiosperm first division - CORRECT ANSWER - asymmetrical with one small side and
one big side. The small cell keeps dividing while the larger one becomes a suspender into the
endosperm.
