Plant Growth and Development
DIRECTIONS: Answer each question either by writing the correct information in the space
provided or by choosing the appropriate response.
1. In the plant kingdom, plants can be loosely characterized into two groups:
_________________ are flowering plants and ______________ are cone bearing plants.
2. Flowering plants can be further divided into ________________, which have leaves
with netted veins, or ___________________ which have leaves with parallel veins.
3. True or False. Monocots and dicots have physiological differences, which cause
them to react differently to weed killers.
4. All plants are classified by the number of growing seasons required to complete a
life cycle. Name the plant classification:
__________________ Plant that passes through its entire life cycle from seed
germination to seed production in one growing season then dies.
__________________ Plant that starts from seed and produces vegetative structures
and food storage organs in the first season. During the second season, flowers,
fruit, and seed develop to complete the life cycle and then the plant dies.
__________________ Plant that lives for many years and typically produces flowers
and seeds each year after reaching maturity.
5. _________________, which are found on the outside of the main root, absorb much of
the water and nutrients for the plant.
6. Xylem tubes in the stem transport _____________ and _______________.
Phloem tubes in the stem transport____________________.
7. A ____________ is the point of the stem at which buds develop into leaves or flowers.
8. To allow the lateral buds to come out of dormancy and begin growth, the
_____________________ bud should be removed.
9. True or False. Leaves absorb sunlight for manufacturing plant sugars in the process
called photosynthesis.
