6.1 Reading #1
: Introduction to the Plant Kingdom
Plants are as necessary to human survival as land, water, and air. Our daily lives would be
impossible to sustain without plants because aerobic life cannot
exist without oxygen from
photosynthesis. Plants provide humans with numerous valuable resources,
ranging from food and
shelter to medicines, oils, perfumes, and industrial products. The majority of organisms that come to
mind when you think of plants are vascular plants. These plants have tissues that transport food and
water, and the majority of them produce seeds. Gymnosperms and angiosperms are two types of seed
plants. Gymnosperms include needle-leaved conifers like spruce, fir,
and pine, as well as less
common plants like ginkgos and cycads. The seeds of these plants are not protected by fleshy fruit.
The majority of seed plants are angiosperms, also known as flowering plants. They include
broadleaf trees (such
as maple, oak, and elm), vegetables (such as potatoes, lettuce, and carrots),
grasses, and flowering plants (roses, irises, and daffodils, for example). While each plant species is
distinct, they all share a common structure: a plant body made up of stems, roots, and leaves. They
all transport water,
minerals, and sugars produced by photosynthesis in a similar manner through the
plant body. Light, gravity, competition, temperature, and predation are all environmental factors that
all plant species respond to.
