In the plant, when a cell divides into two daughter cells, we observe in this experiment Mitosis, which is the cell division that allows the plant to elongate and occurs in the meristematic tissues that are at the ends of the plants. Whereas meiosis is restricted to reproductive tissue and forms gametes that will form new seeds through fertilization, carrying genes from one generation to another.
<h3>How does mitosis occur in plant cells?</h3>
In plant cells, division takes place from the inside out – centripetal cytokinesis. In plant cells, cytokinesis is centrifugal, from the outside to the inside: there is the formation of a lamella, which grows from the center to the periphery and separates the two cells.
With this information, we can conclude that through successive mitotic divisions that the zygote (cell generated after the meeting of gametes) manages to originate all the cells of its organism. Mitosis, therefore, is responsible for the growth and development of embryos.

#SPJ1
Each sieve tube element is normally associated with one or more nucleated companion cells, to which they are connected by plasnodesmata (channels between the cells). Each companion cell is derived from the same mother cell as its associated sieve tube member. Sieve tube members have no cell nucleus, ribosomes, or vacues. Thus, they depend on companion cells to provide proteins, ATP, and signalling molecules
Answer:
The correct answer is a acyl-carnitine readily cross the mitochondrial inner membrane but the acyl CoA do not.
Explanation:
Fatty acids are activated to form fatty acyl CoA by the help of ATP and CoA SH.But the so formed Acyl CoA cannot cross or pass the inner mitochondrial membrane to enter the mitochondrial matrix to initiate beta oxidation of fatty acid.
To overcome this problem fatty acyl CoA is converted to acyl carnitine and the so formed acyl carnitine readily crosses the inner mitochondrial membrane and enters the mitochondrial matrix.
Answer:
The answer is A, because 55+15=70, and 70-67=3
Both the neurons carry afferent information. The axons of the neurons are the afferent nerve fibers, and carry the information to the central nervous system. They are a part of the peripheral nervous system. These neurons are also called as sensory neurons.
