The picture below is of a moss growing on my roof. It shows both the gametophyte and the
sporophyte phases of the life cycle.
Make a sketch and label which part of the moss is the gametophyte and which is the sporophyte.
(Alternatively, you can find a live moss with both phases and take a picture, label it and upload here.)
Label the seta, capsule and calyptra of the sporophyte.
Create a table to compare and contrast the following sets of terms. The table should define each term and outline the significance of each for plant reproduction, structure and/or function. Corm: Rhizome Primary meristems: Secondary meristems
Sclerenchyma: Collenchyma Starch: Druse crystals
Raceme: Cyme

A sporophyte A fern A gametophytearrow_forwardXerophytes have adaptations such as having a waxy leaf cuticle that will make them survive in hot and dry environments. How does this adaptation help reduce water loss?Ā * Ā Ā Ā It increases the ability of the leaf cells to absorb water. NO answer It reduces the surface area for transpiration. It is impermeable to water, thus stops evaporation. It traps moist air, which increases the humidity and reduces the diffusion of water vapor.arrow_forwardVascular plants evolved to have the apomorphic characteristics that enabled them to grow with greater height and thrive with efficiency in sustaining more complex structures. Select one: O True O False The sporophyte structure in vascular plants is dependent on the gametophyte structure. Select one: True False The presence of lignin in the secondary cell wall structure of vascular plants acts as a cementing agent between cellulose fibrils. Select one: True Falsearrow_forward

- Plants Are Adapted to Life on Land Ā 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. Ā Ā Ā Ā Ā Ā Ā Ā Ā Ā Ā Ā Ā Ā 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.arrow_forwardPlease answer asap Characteristic of plants to survive on land Select the following characteristics that allowed plants to survive and reproduce in a land environment. A) Develop a means to prevent their cells and tissues form drying out B) Enclosing the chloroplast in a double membrane to protect the pigments from UV radiation C) Develop a system to transport water and nutrients to their cells D) Strengthen their cell wall with cellulose to support cells against gravity E) Reproductive structures had to change to disperse gametes in the absence of water F) Develop chlorophyll a and b for photosynthesis G) Protect their embryos from the temperature and moisture variations of life on land H) Storage of excess carbohydrates as starcharrow_forwardThe picture below is of a moss growing on my roof.
