Do pteridophytes have flowers?
No, pteridophytes do not have flowers. They are non-flowering vascular plants that reproduce via spores instead of seeds, and they include ferns, horsetails, and clubmosses. Pteridophytes have distinct structures like fronds and strobili but lack the reproductive structures associated with flowering plants.
What parts are not common to all plants?
Not all plants have flowers, as some, like ferns and mosses, reproduce through spores instead. Additionally, not all plants possess seeds; for example, non-seed plants such as liverworts and horsetails reproduce via spores. Furthermore, while most plants have roots, some, like epiphytes and certain aquatic plants, may lack traditional root systems.
What strucures do angiosperms have and gymnosperm lack?
Angiosperms have flowers and fruit, which are structures that gymnosperms lack. Flowers are reproductive structures that attract pollinators, while fruit develops from the ovary after fertilization to protect and disperse seeds. Gymnosperms, on the other hand, produce seeds that are not enclosed within a fruit and do not have true flowers.
How are flowerless plants different to plants with flowers?
Flowerless plants, such as ferns and mosses, reproduce via spores rather than seeds, while flowering plants reproduce through seeds formed after pollination. Flowerless plants generally lack complex structures like flowers and fruits, which are characteristic of flowering plants. Additionally, flowerless plants often have simpler life cycles and rely on water for reproduction, whereas flowering plants can use various pollinators and have more diverse reproductive strategies.
Do all mosses have flowers?
No mosses have flowers they are non-flowering plants.
Do pteridophytes have flowers?
No, pteridophytes do not have flowers. They are non-flowering vascular plants that reproduce via spores instead of seeds, and they include ferns, horsetails, and clubmosses. Pteridophytes have distinct structures like fronds and strobili but lack the reproductive structures associated with flowering plants.
What is a unique feature of ferns in comparison with angiosperms?
Ferns lack the flowers or seeds of the angiosperms. Instead they reproduce by forming spores in two phases, the sporophytic and a gametophytic phase. The second, gametophytic, phase is actually a free-living organism, not a seed.
Do ferns lack seeds?
"They have spores. These are not an exact counterpart to seeds however, they are produced asexually (require no fertilization) as ferns have a 2 stage reproductive cycle."~ Hach on Answers.com
What is the difference between angiosperms and ferns?
Ferns have vascular tissues in the form of xylem and phloem and gametophytic stage dependent on the sporophytic plant body; mosses are lacking xylem & phloem and have sporophytic stage dependent on the gametophytic plant body in the form of capsules.
What do ferns lack?
Ferns are plants, they lack motion.
What do horsetail and ferns have in common?
Horsetails and ferns are both non-flowering vascular plants belonging to the group known as pteridophytes. They reproduce via spores rather than seeds and have a life cycle that includes both a diploid sporophyte generation and a haploid gametophyte generation. Both types of plants prefer moist environments, and they lack true roots, instead having structures that function similarly. Additionally, they possess a similar arrangement of leaves, which are often referred to as fronds in ferns.
What strucures do angiosperms have and gymnosperm lack?
Angiosperms have flowers and fruit, which are structures that gymnosperms lack. Flowers are reproductive structures that attract pollinators, while fruit develops from the ovary after fertilization to protect and disperse seeds. Gymnosperms, on the other hand, produce seeds that are not enclosed within a fruit and do not have true flowers.
Fossilized non-seed vascular plants from the period have been identified?
Fossilized non-seed vascular plants from the period such as ferns, horsetails, and club mosses have been identified. These plants are known for their primitive reproductive structures and lack of seeds, reproducing via spores instead. Fossil evidence of these plants help scientists understand the evolution of plant life on Earth.
What helps ferns club mosses and horsetails grow taller than mosses?
Ferns, club mosses, and horsetails have vascular tissues that allow them to transport water and nutrients more efficiently than mosses, which lack these structures. This vascular system supports greater height and structural complexity, enabling them to grow taller. Additionally, their ability to produce spores instead of relying solely on water for reproduction allows them to thrive in a wider range of environments. These adaptations give them a competitive advantage over non-vascular mosses.
How are flowerless plants different to plants with flowers?
Flowerless plants, such as ferns and mosses, reproduce via spores rather than seeds, while flowering plants reproduce through seeds formed after pollination. Flowerless plants generally lack complex structures like flowers and fruits, which are characteristic of flowering plants.

Do all mosses have flowers?
No mosses have flowers they are non-flowering plants.
What is a vegetative organism?
A vegetative organism refers to a type of organism that mainly grows or reproduces through asexual means, such as budding or fragmentation. These organisms typically lack specialized reproductive structures like flowers or seeds and can propagate through the replication of their vegetative tissues. Examples include plants like ferns and fungi like molds.
