Make a complete moss life cycle with the following phases and structures. Note: download the images of Mnium from this link and arrange them in the exact sequence to make the lifecycle. Lifecycle structures with cell division: Meiosis, fertilization within archegonium, capsule (sporangium), spores (n), protonema (n) (Image), male gametophyte (n) (Image), female gametophyte (n) (Image), antheridia (Image), archegonia (Image), sperm, egg, water, zygote (2n), embryo, young growing sporophyte (2n), mature sporophyte (2n) (Image), rhizoids. You can insert the non-image part, using the textbox and fill out the suitable s text. For symbol, click on the shape option and inter in your lifecycle diagram at the required place
Define the sporophyte ? Explain why it is helpful for plants ?
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.

- READ THE FOLLOWING INSTRUCTIONS: Bryophytes in which the gametophytes are "leafy" in appearance and the sporophytes grow conspicuously from the tips of the gametophyte plants. STEP 1: Examine the mass of moss plants and then select one or two individual gametophyte plants and note the leaf-like (not true leaves because they lack conducting tissue) structures which are arranged around a central, vertical "stem-like" stalk and root-like rhizoids which anchor the plant and absorb water and nutrients. STEP: The sex organs are in the tips of the plants and must be seen with the microscope. Study a slide of a vertical section through head of a mate plant and note the many antheridia. STEP 3: Examine a slide through a vertical section of a female plant. Note the many upright archegonia each on a tall stalk and each with a swollen base or venter containing an egg and an elongate neck. Note the filamentous paraphyses between the archegonia. STEP 4: Examine a living or preserved…arrow_forwardExplain the life cycle of a fern. Begin with the dominant portion of their life cycle and work your way through the rest including specific names of structures, types of cell division used, and nuclear conditions. Along with your explanation (paragraphs, bulleted points, etc.), I would like for you to discuss in a few sentences how this life cycle is more advanced than a typical moss’s life cycle and, in a few sentences, how it is not quite as advanced as a typical pine’s life cycle.arrow_forwardAs part of an experiment you are required to observe the external features of a fern. State what microscope would you use and give reasons why? You have been provided with a plant showing the rooting system and the stem with several leaves. Give SIX features that you will look for to determine whether this is a monocotyledonous plant or a dicotyledonous plant. Present your answer in a clear, logical manner. In an experiment students were given the following materials and apparatus: - juices from three local fruits; 4% glucose solution; Benedict's solution; test tubes, beakers, syringes and boiling water bath. Describe CLEARLY the procedure that can be used to estimate the amount of glucos present in each juice. Use numbered steps in your answer.arrow_forward
- The non-vascular plants are represented today by three phyla of small herbaceous plants namely: Phylum Hepatophyta, Phylum Anthocerophyta, and Phylum Bryophyta. Cite and explain how the structure fits function in bryophytesarrow_forwardCompare and contrast the three phyla of bryophytes using the specified bases in the Table below. Bases Hepatophyta Anthocerotophyta Bryophyta 1. Growth form (leafy or thallose) 2. Arrangement of leaves on the stem for leafy types 3. Mechanism of spore dispersal 4. Presence of stomata on the sporophytes 5. Presence of primitive conducting cells 6. Presence of chloroplast on the sporophyte 7. Structure of the protonema 8. Presence of symbiotic cyanobacteria 9.

They are also commonly monecious (single "house", or thallus for male and female gamete production). The photo below shows a whole mount (w.m.) of a fern gametophyte at 40x. Make a sketch of the specimen and label the following structures: archegonium, antheridium, mature gametophyte (a.k.a. prothallus), rhizoids 90arrow_forward
- Byrophytes 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.arrow_forwardProvide a picture and label a diagram that illustrates the following features: holdfast (a root-like structure that attaches the seaweed to the bottom), stipe (a stem like structure, but not a true stem because it lacks vascular tissues), blades (leaf-like structures, but not true leaves because they lack veins), and pneumatocyst (an air-filled float).arrow_forwardReproductive structures are the critical factors in distinguishing algae from true plants of kingdom Plantae. What is one fundamental difference between reproductive structures in these two groups?arrow_forward
- Bryophytes form a monophyletic group that transitions between green algae and vascular plants. Describe at least one similarity and one difference between bryophyte reproduction and green algae reproduction.arrow_forwardUse the image to correctly fill in the following blanks. The whole specimen is a [A], a gametophyte structure found in the phylum [B]. The structures found within the circle are called, [C] and the arrows point at examples of [D].
