Answer:
1. The reproductive parts of angiosperms are located within the flower called the stamen and pistill and the female part is called Pistil and The male part is Stamen.
2. In angiosperms, pollen produces male cells. Pollen sticks to the female stigma and travels down the style to the ovary. This is where fusion of pollen and ovule will occur to make seeds.
3. The reproductive parts of plants are part of the shoot system.
4. Plant growth and development is regulated by harmone which send chemical messages.
Explanation:
Flowers are the reproductive part of the plant which produces seeds. In flowers, male organ is called stamen and female organ is called pistill or carpals. Stamen has two parts i. e. anther and filament. Pistill has three parts i. e. stigma, style and ovary. Anther contains pollen which fall on stigma and make a tube which goes towards ovary where ovules are present. When pollens fuse with ovules, forming a seed which is a baby plant.
Answer:
Offspring with purple colour are either homozygous or heterozygous for purple colour while the offspring with white flowers are homozygous for the recessive white colour
DNA damage systematically causes mutations in the genome and changes genetic information.
The pathways of DNA damage are divided into
Exogenous: due to physical factors (such as UV rays and X and gamma ionizing rays) and chemical factors (desaminants, alkylating agents, oxidizing agents, adducts, nucleotide analogues ...).
Endogenous: they are physiological factors (oxidation desamination, depurination ...).
<u>The consequences of these lesions are:
</u>
* Nucleotide substitution (one or more nucleotides)
* Insertion and deletion of nucleotides (one or more nucleotides): addition or deletion of nucleotides within the genome.
