(a) cuticle (b) unicellular gametangia (c) stomata (d) multicellular embryo (e) alternation of generations
- i) list TWO adaptations that show that the plant conserves water.ii) Photosynthetic cells produce starch and may be stored. Describe how one may test for the presence of starch on a piece of potato tissue. iii) Give TWO characteristics of monocotyledonous plants. d. The transition of plants from an aquatic environment to a terrestrial one has broughtabout many evolutionary adaptations for plants to survive on land. Give ONE adaptationfor each of the following divisions:i) Mosses: ii) Gymnosperms.Please answer asap Characteristic of plants to survive on land Select the following characteristics that allowed plants to survive and reproduce in a land environment.

- Identify four derived traits that distinguish plants from charophyte green algae and facilitate life on land. Explain.State two important features of seed vascular plants and relate how these contributed to their enormous success over the seedless non-vascular and vascular plants.Discuss the adaptations that have enabled flowering plants to overcome the following problems associated with life on land.* The absence of an aquatic environment for reproduction.* The absence of an aquatic environment to support the plant body.* Dehydration of the plant.
- 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. Name 3 characteristics of plants that help them conserve water and protect them from drying.One 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 FalseByrophytes are usually found in areas that are very wet or damp at least part of the year. Which of the following statements describes characteristics of byrophytes that make them dependent on water? State all that numbers that apply. 1. They have a dominant gametophyte phase. 2. They have swimming sperm that need water so they can swim to fertilize the eggs of other nearby plants. 3. They do not have lignin-stiffened vascular tissue or roots to effectively distribute water throughout the plant.
