Answer:
They are small because they are growing on bare surfaces, not even soil, so they're just growing on abiotic things like rocks, so the first plants are more like weeds, lichens, small mosses, etc... because these are the only types of plants suited to turn this habitat back into its original climax community through means like nitrogen fixation. Also, because there's probably no to little nutrients there which can cause nutrients to be a limiting factor to their growth and cause them to be stunted. Need me to elaborate more?
Explanation:
A chromosome is a structure that is made of a chemical known as deoxyribonucleic acid, or DNA as well as protein. Chromosomes are found in the nucleus of cells. Chromosomes contain many genes.
A gene is a molecular unit of heredity. Each gene codes for a polypeptide, which becomes a protein that performs a function in a living thing. The DNA molecules are very long and in order to fit inside the nucleus of a cell, they are highly coiled and condensed. During sexual reproduction, one haploid set of chromosomes is given to the offspring from each parent, forming a diploid amount of chromosomes in the offspring.
Since chromosomes contain all of our genes, an organism that reproduces sexually gets a combination of genes from both parents. Genes that are expressed produce an organism's phenotype.
It is used to demonstrate the importance of chlorophyll in photosynthesis. Plant with variegated leaves is de starched and then placed in the sunlight for a few hours, then the iodine test for starch is carried out. The green parts of the leaves will test positive for starch and therefore turn blue black. The non-green parts did not photosynthesize die to absence of chlorophyll and iodine color will remain brown.
