Spermatophytes are a group
of plants that produce seeds for reproduction. They are also known as seed
plants and are divided into two major groups: gymnosperms and angiosperms.
Here are some salient
features of spermatophytes:
Seeds
The most important feature
of spermatophytes is that they produce seeds, which protect and nourish the
developing embryo. Seeds contain the embryo, stored food, and a protective
outer covering.
Vascular tissue
Spermatophytes have
well-developed vascular tissues, including xylem and phloem, which transport
water, nutrients, and sugars throughout the plant.
Roots, stems, and
leaves
Spermatophytes have
well-developed roots, stems, and leaves. The roots anchor the plant and absorb
water and nutrients from the soil. The stem provides support and transports
nutrients and water between the roots and leaves. The leaves are the site of
photosynthesis, where the plant produces food using sunlight.
Reproductive
structures
Spermatophytes have
reproductive structures that are specialized for seed production. In
gymnosperms, the male reproductive structures are cones, while the female
reproductive structures are ovules. In angiosperms, the male reproductive
structures are flowers, and the female reproductive structures are located in
the ovary.
Dominant generation
Spermatophytes have a
dominant sporophyte generation, which is the plant that produces spores. The
gametophyte generation is reduced and is dependent on the sporophyte for
nutrients and protection.
Spermatophytes are an
important group of plants that have evolved adaptations to survive and
reproduce in a variety of environments. They are diverse and include some of
the largest and oldest organisms on Earth, such as the giant sequoia and the
bristlecone pine.
