QUESTION POSTED AT 23/09/2019 - 04:15 AM

What is the Mitosis cell cycle, give a description for each stage.

The four main phases of mitosis are:

Prophase- In the first half:The chromosomes start to shrink. The cytoskeleton begins to form the mitotic spindle, which will grow between the centrosomes and organize the chromosomes.The nucleolus goes away.
                  In the second half: The chromosomes become extremely compact. The nuclear envelope disappears and all the DNA comes out. Some of the mitotic spindle starts to catch chromosomes.

Metaphase- The mitotic spindle moves all of the chromosomes across the middle of the cell.

Anaphase- The two chromatids of each chromosome are pulled apart from each other and become their own chromosomes. Loose microtubules push the ends of the cell to make it longer.

Telophase- The mitotic spindle is broken back down into microtubules. Two new nuclei appear (one for each new cell). The chromosomes return to their normal form (not all squished down).

Another big step is cytokinesis, which starts either during Anaphase, or Telophase. In animal cells, the cell is pinched around the middle to create the two new cells. In plant cells, a cell plate comes into the middle of the cell and separates it into the two new cells.

The main four steps can be remembered using the acronym PMAT.

Photosynthesis is important to living organisms because it is A.the foundation of most food chains. B.the source of nitrogen gas in the air. C.how animals get carbon dioxide to breathe. D.the process that occurs in most ecosystems.

Photosynthesis is important to living organism as it is the foundation of most of the food chains.

Further Explanation:

Food chain is a linear advancing process from producers to the last/apex or tertiary consumers. This chain starts from producers which are the organisms such as plants. Plants undergo photosynthesis and produce simple carbohydrates which are the source of energy for every organism which is directly or indirectly dependent on them.

Let us consider an example of linear food chain,

Lion feeds on deer and deer consumes grass for nutrition.

In the above given example grass is the producer and is the base of a food chain or we can say a starting point of a food chain. While the deer is a primary consumer a herbivore which is directly dependent on grass for food. The lion consumes the deer for nutrition and is a apex carnivore for the given example. The lion is indirectly dependent on the producer that is grass for nutrition.

Therefore the photosynthesizing plants play a vital role in the continuity of life as the energy entrapped by them is passed through all the trophic levels.

The producers (plants) thus; are the base or foundation of most of the food chains and play a vital role for living processes and organisms.

QUESTION POSTED AT 23/09/2019 - 04:13 AM

Can a cell live without a cell membrane or Chloroplast ?

No bc Mitochondria are rod-shaped organelles that can be considered the power generators of the cell, converting oxygen and nutrients into adenosine triphosphate (ATP). ATP is the chemical energy "currency" of the cell that powers the cell's metabolic activities. This process is called aerobic respiration and is the reason animals breathe oxygen. Without mitochondria (singular, mitochondrion), higher animals would likely not exist because their cells would only be able to obtain energy from anaerobic respiration (in the absence of oxygen), a process much less efficient than aerobic respiration. In fact, mitochondria enable cells to produce 15 times more ATP than they could otherwise, and complex animals, like humans, need large amounts of energy in order to survive.
