Botany - Unit 1 Taxonomy Exam Questions
and Answers with Verified Solutions | Latest
Updated 2026
Green Algae A group of photosynthetic organisms found
in
freshwater, marine, and terrestrial
environments,
characterized by their green color due to
chlorophyll.
Bryophytes Nonvascular plants, such as mosses and
liverworts,
that reproduce via spores and typically
grow in
moist environments.
Pteridophytes Vascular plants that reproduce via spores,
including ferns and horsetails,
characterized by the
presence of true roots, stems, and leaves.
Gymnosperms Seed-producing plants that do not form
flowers or
fruits, with seeds typically exposed on
cones, such
as conifers.
, Angiosperms Flowering plants that produce seeds
enclosed
within a fruit, representing the largest
group of
plants in terms of species diversity.
Xylem The vascular tissue in plants responsible
for the
transport of water and dissolved minerals
from the
roots to the rest of the plant.
Phloem The vascular tissue in plants responsible
for the
transport of sugars and other metabolic
products
downward from the leaves.
Lignin A complex organic polymer found in the
cell walls
of many plants, providing structural
support and
rigidity.
Stomata Small openings on the surface of leaves
that allow
for gas exchange (CO2 and O2) and
transpiration in
plants.
