Answer: A, through extensive testing and the accumulation of several lines of evidence
Explanation:
<h3><u>Answer;</u></h3>
Label A; Mitochondria.
Label B; Nucleus.
Label C; Golgi apparatus.
Label D; Rough endoplasmic reticulum
<h3><u>Explanation;</u></h3>
- All the above are various organelles in a eukaryotic cells each carrying different cellular activity to enhance the functioning of a cell.
Label A; Mitochondria.
- <u>Mitochondria</u> is the powerhouse of the cell which converts glucose to energy rich molecules of ATP, through the process of cellular respiration.
Label B; Nucleus.
- <u>Nucleus</u> contains the genetic material or DNA, RNA , nucleolus, chromatin fibres and proteins. It contains the chromosomes which control the hereditary characteristics.It also regulates all the activities of the cell.
Label C; Golgi apparatus.
- <u>Golgi apparatus;</u> they are also called Golgi bodies. They function in modifying, sorting and packaging of proteins for secretion. They are also involved in the transport of lipids around the cell, and the creation of lysosomes.
Label D; Rough endoplasmic reticulum
- <u>The rough endoplasmic reticulum</u> provides surface for protein synthesis. It is also used to transport cellular contents from one cell to another.
- The risbosomes attached on the rough endoplasmic reticulum are resposible for the protein synthesis through the process of translation.
<h2>Answer :</h2><h3>Part 1:</h3>
Yes, embryos have leaves which are known as cotyledons.
Plants with two embryonic leaves are termed dicotyledonous ("dicots") .
Plants with one leave are known as monocotyledon.
<h3>Part 2:</h3>
Six (6) Chromosomes.
As embryo is formed from the combination of egg and sperm. If embryo has 12 chromosomes then sperm will have half means 6 chromosomes.
<h3>Part 3:</h3>
Six (6) Chromosomes.
As embryo is formed from the combination of egg and sperm. If embryo has 12 chromosomes then egg of a bean or corn will have half means 6 chromosomes.
