This figure summarises the life cycle of a seed plant. The blue circles named A and B represent the sexually mature individual of each phase of the life cycle. 1) What is this life cycle called? 2) Plant B is in the diploid phase. What is another name for this plant? 3) If A is the haploid phase, in which phase would you find sepals? Write just the letter of the individual corresponding to the correct phase 4) If B is the haploid phase, in which phase would you find synergids? Write just the letter of the individual corresponding to the correct phase 5) If B is the diploid phase, in which phase would you find the nucellus? Write just the letter of the individual corresponding to the correct phase 6) If A is the diploid phase, in which phase would you find the sperm cells? Write just the letter of the individual corresponding to the correct phase 7) If A is the diploid phase, in which phase would you find selection on flower colour?

a) What role does 'alternation of generation' play in encouraging survival of simple plants like the Bryophytes and Hepatophytes. b) i) Anthrophytes also show alternation of generation. Identify the structures that represent these two stages in its life cycle. ii) Explain why the alternation of generation in Anthrophytes must be different from that of the Bryophytes.(-

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

Below is a series of pictures of a eudicot stem tip (I.s.), Coleus sp.. Much of what plant biologists have learned about leaf development have occurred by studying stem tip genetics. 40x (I.s.) Make a sketch of the 40x stem longitudinal section and upload it here with the following structures labeled: apical meristem, leaf primordium, axillary bud, procambium, vascular tissue (need to look lower down the stem for these sub-tissues), ground meristem, cortex, pith
Put 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.
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).
