Answer:
<u>Cuticle</u> - It also has a waxy material that protects the leaf from attacks by bacteria, protects inner tissues from mechanical damage and acts as a water proof layer to prevent excessive water loss.
<u>Palisade mesophyll</u> - They have many chloroplasts used to absorb light energy used for photosynthesis.
<u>Spongy mesophyll</u> - The cells are loosely packed together leaving air spaces that allow for air circulation and gaseous exchange.
<u>Guard cell</u> - They have thick inner walls and thin outer walls to control the opening and closing of the stomata.
Some of the examples of specialized cells are Reproductive cells, Nerve cells,blood cells. Red blood cells specialize in carrying oxygen throughout the body.
<u>Explanation:</u>
When a cell performs a function or a task that others cannot do then those cells are called as specialized cells. They are useful in performing special functions like transportation of something throughout the human body.Some of the cells are responsible in performing some special tasks that others cannot do.
Examples of specials ed cells includes nerve cells, blood cells, reproductive cells. These cells are responsible in performing a particular function. For instance nerve cells which are termed as neurons. They are responsible in sending signals with an electrical impulse. Blood cells are responsible in taking oxygen throughout the human body.
Answer:
Speciation has become complete when organisms of one population do not recognize the mating call of another population and so mating does not occur. Which of the following statements about reproductive barriers and speciation is true? Speciation can occur with even a single gene mutation if that mutation involves reproductive barriers.
Explanation:
<span>Apart from the plants and algae which are well-known to be able to perform photosynthesis, other organisms capable of doing so are some specific species of bacteria especially those which contain the green pigments called chlorophyll necessary for photosynthesis. These bacteria are also capable of absorbing carbon dioxide.</span><span />
Answer:
The protein synthesis.
Explanation:
The question is not complete, here is the complete question:
This is a two-part process that ends in the assembly of proteins at the ribosomes within cells. The first part, transcription, begins in the nucleus, when the DNA code is transferred to mRNA. The second part, translation, takes place at the ribosomes, where both mRNA and tRNA work to assemble proteins.
The events in the question are describing protein synthesis.
I hope this answer helps.
