Concept Introduction:
The non-vascular plants are easily observed. There are seedless vascular plants which have 12000 species, but do not produce seeds. The bryophytes are one of the non vascular plants.

- Imagine that you are a member of a research group conducting research on fruit type and seed dispersal. Your group has submitted a paper to a peer-reviewed journal that addresses the factors that impact fruit type and seed dispersal mechanisms in plants of Central America. The editor of the journal communicates that your paper may be published if you make ‘minor revisions’ to the document.Unit 8 DQ Question: Why is seed dispersal important in the life of plants? What would be the consequences of having seeds that simply fell to the ground underneath the parent tree? (Editor’s note: addressing this question will provide needed background information to the ‘Introduction’ of your paper).arrow_forwardPut the following 3 fictional plants in order from earliest to most recent according to their characteristics: A. The Terpad Plant: This plant reproduces using spores and has proper leaves and vascular tissue. B. The Feltris Plant: The Feltris plant lives in moist environments since it doesn't have any vascular tissue to maintain hydration throughout the plant. This plant has no roots either but has small root-like structures called rhizoids which help anchor them to the ground. Water is also required in order for fertilization. C. The Lancelot Plant: This plant can grow in either moist or dry environments, has true roots, stems and leaves and reproduces via seeds which develop within an ovary.arrow_forwardOne evident apomorphy evolved in vascular plants is the establishment of true leaves which is characterized by the incorporation of the vascular system. Select one: True False The calyptra in mosses generally function in the regulation of gas exchange and water uptake. Select one: True False Elaters are non-sporogenous cells with spiral wall thickenings and is mainly for spore dispersal of liverworts. Select one: O True Falsearrow_forward

- Plants Are Adapted to Life on Land Plants developed from a group of green algae (members of Kingdom Protista) called the charophytes. Like these green algae, plants have a life cycle called the alternation of generations. Draw a diagram of the basic life cycle of a plant, showing the alternation of the sporophyte and gametophyte generations. Unlike green algae that live in water, plants live on land. Being surrounded by air means that they risk losing too much water through evaporation and dying from dehydration.
