Eill in the Blank: Please write the correet word or short phrase to the left of the statement. Be specific. (8 pts) In sexual reproduction of certain green algae, gametes fuse to form a zygote, which then undergoes meiosis to produce spores. The spores then divide many times to become gametophytes. What land plant life cycle stage is absent here? Period from about 350-300 mya, when the seedless plants dominated the landscape initially and seeds first evolved Specific type of reproduction that occurred if an apple tree made offspring in a way that involved only one parent plant and spores In the very early spring, the apical buds of a maple tree act as regions for sugar transport, because that is where new leaves are just beginning to grow Refers to the several patterns in which leaves can be arranged on a stem. Mint's is described as opposite and tomato's is described as helical or spiral. If a mature, functional moss sporophyte is completely brown, it must have gotten the sugar it needed from this. The triploid tissue resulting from double fertilization A species like pumpkin, that produces unique male and female flowers on the same plant Root cells release CO2 and pump protons into the soil. Both help them absorb K'. Ca and Mg" from soil particles in this process Gymnosperms possess one in the ovule, while angiosperms possess two. Positive root pressure can lead to this process, causing water droplets to form on leaves overnight. Name an example of a specific patterm of arrangement of flowers on a stem. e process in which an egg generates a zygote withour fertilization. An example of a common grocery-store fruit that shows that the flower from which it developed had just one ovule in its ovary The fundamental role of a female gametophyte, in any land plant or alga's sexual reproduction, is to produce (a). In land plants, the female gametophyte (or the female part of the gametophyte) also (b) a) b)Explanation / Answer
Answere :
1. The Diploid stage or sporophytic phase absent such green alga.
2. Carboniferous period is the period, when the seedless plant intiate to dominate landscape and seeds first evolved.
3. Asexual reproduction occured during which a single parent plant produce offspring.
4. Phyllotaxy is the arrangment of leaves on stem of plant.
5. Triploid endosperm is triploid tissue in plant formed by double fertilization.
6. Autoecious plant species produce male and female flower on same plant.
7. During plant respiration, root releases CO2 and pump proton into the soil.
8. Integument is found singly in gymenosperm and two in angiosperm.
9. Guttation occur through positive root pressure and causing water droplet to form on leaves overnight.
10. Spike inflorescences is an example of specific pattern of arrangement of flower on stem
11. Parthenogensis is the process of developement of zygote from egg without fertiliization.
