The correct answer to the question above is action. The potential must be strong enough to send an action potential to the CNS (Central Nervous System.) An action potential is a short-term event that causes the electrical potential of a cell.
Answer:
The tetrad is the four spores produced after meiosis of a yeast or other Ascomycota, Chlamydomonas or other alga, or a plant.
Answer:
Spore
Explanation:
In the process of sexual reproduction, specialized haploid cells from two organisms, which can be called the (+) and (−) mating types, come together to produce a diploid zygote. The zygote after then will go through meiosis to produce four haploid cells termed spores. The spore, houses a new genetic combination from two parents with its capability to be dormant for varying time range.
Plants possesses a life cycle that switches between a multicellular haploid organism and a multicellular diploid organism. Take the ferns for example, both the haploid and diploid plant phases are free-living. The diploid plant is known as a sporophyte due to its ability to form haploid spores by meiosis. The spores grow into a multicellular, haploid plants termed gametophytes since they can have gametes. The gametes of two individuals will come together to produce a diploid zygote that is the sporophyte. The attached image 1 explains more on this.
Fungi, take for instance black bread mold (Rhizopus nigricans), possess haploid-dominant life cycles. The haploid multicellular stage give rise to specialized haploid cells by mitosis that come together to produce a diploid zygote. The zygote pass through meiosis to form haploid spores. Each spore will lead to a multicellular haploid organism by mitosis. The attached image 2 explains more on this.
Answer:
seedless plants do not bear seeds for propagation, whereas seed plants bear seeds for multiplication.
Explanation:
The difference between seed plants and seedless plants is that seedless plants do not bear seeds for propagation, whereas seed plants bear seeds for multiplication. The plant kingdom is traditionally divided into four main divisions, i.e Thallophyta, Bryophyta, Pteridophyta and Spermatophyta
The sporophyte is the dominant generation, but multicellular male and female gametophytes are produced within the flowers of the sporophyte.
In many plants, the sporophyte generation is the dominant generation. This means that the sporophyte is larger and lives longer than the gametophyte generation.
hope it helps you
have a great day!
