Gymnosperms are the first and most recent nonflowering plants to produce seeds. Gymnosperms lived along with fern and other nonflowering seedless plants for about 200 years. It was about 130 million years ago t
How do spore-bearing plants reproduce? How do flowerless, seedless plants reproduce? How are plants in the family Asteraceae pollinated? Where does fertilization occur in flowering plants? How do seedless nonvascular plants reproduce? How do seeds develop in angiosperms?
Non-flowering plants include gymnosperms, which produce seeds in a hard cone, but no fruit, such as conifers, cycads and gingko. Other non-flowering plants reproduce using spores. Mosses and Ferns:Mosses and ferns represent some of the earliest plant adaptations to be successful on land, with...
Thus, many classifications have been suggested for flowering plants. Taxonomists, systematicists, and botanists write floras based on the interpretation of their favored taxonomic authority. This is why no one can say for sure just how many plant families exist. Some authorities maintain that there...
Examples of vascular plants Fern A fern is an example of lower vascular plants that have specialized conducting tissues; xylem and phloem, necessary for the transport of water, mineral, and food particles. These are non-flowering vascular plants with true stems, roots, and leaves and reproduce ...

- Begin by explaining that fruits are the mature ovaries of flowering plants. After fertilization, the ovary develops into a fruit, while the ovule develops into seeds. 2. True Fruits: - Define true fruits as those that develop directly from the ovary of the flower after fertilization. - ...
1.2 pages Groups of Vascular Plants Vascular plants: divided into 3 smaller groups Angiosperms- Flowering plants Gymnosperms- cone bearing. Vascular vs. Nonvascular Compare and contrast the characteristics of vascular and nonvascular plants. Both. ...
Genetic redundancy is common in flowering plants, especially food products such as seedless watermelon and strawberries. If one genetic copy is damaged, there’s still another available to do the job. Secondly, seed coats contain chemicals called flavonoids that act as sunscreens, protecting the ...
Non-flowering plants are generally divided into two main groups, which reflect their method of reproduction. One group is called gymnosperms and reproduce by seeds and the remaining reproduce by spores.Answer and Explanation: Become a member and unlock all Study Answers Start today. Try it now ...
