Lesson 3: Botany

Question 1

botany

Answer 1

a branch of biology dealing with plant life and how plants grow

Question 2

horticulture

Answer 2

the science and art of cultivating flowers, fruits, vegetables, turf, and ornamental plants in an orchard, garden, nursery, or greenhouse, on a large or small scale.

Question 3

horticultural

Answer 3

an adjective used to describe something relating to horticulture, or produced under cultivation.

Question 4

horticulturist

Answer 4

a noun referring to a specialist in horticulture.

Question 5

plant classifications by use

Answer 5

edibles; ornamentals/landscape plants; potted plants, houseplants, gift plants

Question 6

plant classifications by climatic requirements

Answer 6

temperature; season; tender or hardy; hardiness

Question 7

plant classifications by ecological adaptations

Answer 7

alpine plants; prairie plants; woodland plants; wetland plants; xeric plants

Question 8

native plants

Answer 8

plants adapted to a given area during a defined time period. In America, the term often refers to plants growing in a region prior to the time of settlement by Europeans.

Question 9

adapted plants

Answer 9

those that reliably grow well in a given habitat without specific attention from humans. adapted plants are considered low maintenance.

Question 10

plant classifications by stem and leaf characteristics

Answer 10

herbaceous or woody; deciduous, evergreen, or semi-evergreen; broadleaf, needle-leaf, grass-like

Question 11

growth habit

Answer 11

the genetic tendency of a plant to grow in a certain shape and attain a certain mature height and spread (e.g., trees, shrubs, vines)

Question 12

plant classifications by life span

Answer 12

annuals; biennials; perennials

Question 13

6 distinct structures (organs) of plants

Answer 14

roots, stems, leaves, flowers, fruits, seeds

Question 15

3 systems of plant tissue

Answer 15

dermal (separates plant from outside world), ground (forms bulk of plant body and carries out essential metabolic functions), vascular (conducts water and nutrients throughout the plant)

Question 16

photosynthesis

Answer 16

the process of using chlorophyll to capture light energy and convert it to energy stored in sugars. photosynthesis uses light energy, carbon dioxide, and water to generate glucose with a byproduct of oxygen.

Question 17

respiration

Answer 17

the process of metabolizing (burning) sugars to yield energy for growth, reproduction, and other life processes. respiration uses glucose and oxygen to generate kinetic energy, with a byproduct of carbon dioxide and water.
