Answer: A plant root is an example of an ORGAN.
Explanation:
Organ consist of specialized cells that come together to perform similar function.
Plants have different organs which are leaves, stems, and reproductive organs which perform specialized functions.
Leaves, stems and roots are vegetative organs of the plants while flowers,seeds and fruits are reproduce structures.
Roots help to anchor the plant to the soil, they absorb nutrients and water and transport them to the stem.
It should begin with a question
prophase is the phase where centrioles move to opposite poles
Answer:
Protein molecules.
Explanation:
Protein, highly complex substance that is present in all living organisms. A chain of amino acid residues is called a polypeptide which is a bond form by the carboxylate ion on one end and the -Nh2 on the other end via condensation reaction.
Proteins are large biological molecules (macromolecules), which consists of one or more long chains of amino acid residues. Proteins perform certain functions in organisms like Enzymes - catalysing metabolic reactions, DNA replication, responding to stimuli, providing structure to cells, transporting molecules from one location to another etc.
Proteins differ from one another in their amino acid sequence, which is dictated by the nucleotide sequence of their genes, which usually results in protein folding into a three-dimensional structure that determines its activity.
A gamete is randomly getting a copy of a chromosome from its mother and father. This means that gamete will get #1 from the mother and the next chromosome will be a pure chance of getting chromosome #2 from mother or father.
Explanation:
- Meiosis is the process that separates the two chromosomes and giving one copy of each to the gamete. This is the reason why egg and sperm together are forming zygote which is diploid.
- The main advantage of sexual reproduction is that each clone is different. Each and every egg is different from each other. This is the same in the case of sperm too.
- At the end of meiosis, males will have 1 cell with 4 sperms all are different in nature, but in females, it will one egg because, during cell division, one cell will hog the cytoplasm.
