In the alteration of generations life cycle the spore undergoes mitosis to become a A) gametophyte B) sproohyte C) spore D) game
Eva8 [605]
<span>A mature sporophyte produces spores by meiosis, a process which reduces the number of chromosomes to half, from 2n to n. Because meiosis is a key step in the alternation of generations, it is likely that meiosis has a fundamental adaptive function. The nature of this function is still unresolved (see Meiosis), but the two main ideas are that meiosis is adaptive because it facilitates repair of DNA damages and/or that it generates genetic variation. The haploid spores germinate and grow into a haploid gametophyte. At maturity, the gametophyte produces gametes by mitosis, which does not alter the number of chromosomes. Two gametes (originating from different organisms of the same species or from the same organism) fuse to produce a zygote, which develops into a diploid sporophyte.</span>

What living systems have distinct structures and sets of functions? Be sure to refer to class notes for
Murrr4er [49]

Answer:

Cells.

Explanation:

A cell can be defined as the structural, fundamental, biological and functional unit of life. Cells are found in all living organisms because they are the basic unit of life.

Generally, cells have the ability to independently replicate themselves. These cells can be compared to the kind of structures found in a business or factory, where you have different workers performing different functions.

In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles.

<em><u>Factory worker = Cell organelle.</u></em>

1. Chief executive officer = Nucleus.

  • The nucleus controls all the activities taking place in the cell and the synthesis of proteins.

2. Power house = Mitochondrion.

  • The mitochondria provides all the energy required in the cell by transforming energy forms.

3. Maintenance team = Lysosomes.

  • They are responsible for absorbing materials and breaking the materials taken in by the cells.

4. Functional managers = Chromosomes.

  • They give sets of instructions for the synthesis of products.

5. Assembly line workers = Ribosomes.

  • They are involved in the build up of proteins.

6. Assembly line = Endoplasmic Reticulum.

  • This is where the ribosomes perform their tasks.

7. Security and support = Cytoskeleton.

  • They help to maintain and support the shape of the cells.

8. Drivers or messengers = Vesicles.

  • They ensure proteins are properly transported to the right and exact location.

9. Packaging unit = Golgi apparatus.

  • Prepares the protein for export by chemically tagging them.

10. Gate man/procurement unit = Cell membrane.

  • It is the wall of the cell and typically controls what leaves and enters the cell.

Hence, cells are living systems that have distinct structures and sets of functions.

For energy, a plant breaks apart some of the small sugars it builds. What does the plant do with the rest of its small sugars?
balandron [24]

Answer:

The plant stores them as starch

Explanation:

A typical plant synthesizes sugars from photosynthesis by using water and carbon dioxide.

6CO_2 + 6H_20 + energy --> C_6H_1_2O_6 + 6O_2

Parts of the sugar synthesized via photosynthesis is used to generate energy during respiration. The energy generated is useful for other metabolic processes in the plant's body.

C_6H_1_2O_6 + 6O_2 --> 6CO_2 + 6H_20 + energy

<em>The remaining sugar is utilized in the synthesis of starch and stored in the various tissues of the plant.</em>
