Cell membrane helps to enclose the cell organelles and cytosol inside a cell. ... A cell wall is a ridgid, protective layer and it covers the cell membrane. For plants, cell walls are mainly made up of cellulose, while a cell wall in bacteria is made up of peptidoglycan,and for fungi it is made up of chitin.
Answer:
Due to other differences.
Explanation:
The plants, fungi, and prokaryotes all have cell walls, we place them in different taxa because of the other differences such as mobility, mode of nutrition etc. Plants and fungi are not mobile means can not move from one place to another whereas prokaryotes are mobile. Fungi and prokaryotes are heterotrophs means that feed on other organism whereas plants are autotrophs means make their own food. There is also difference in their cell wall i.e. the cell of plants is composed of cellulose, the cell wall of prokaryotes especially bacteria is composed of peptidoglycans and the cell wall of fungi is composed of chitin.
Without enzymes, the temperature inside cells would increase rapidly.
Without enzymes, biochemical reactions would cease completely.
Without enzymes, chemical reactions would not occur quickly enough to sustain life.
Without enzymes, ribosomes would break down proteins, rather than build them.
Fossils can be classified by their morphology (how they look), ethologically (how they acted), and toponomically (where they are in the substrate layers) to produce phylogenetic trees. However, more recent advances in genetic technology allow us to extract DNA from more recent fossils that have not had too much breakdown of the DNA, and we can much more accurately classify species from that information, and also provide much more accurate phylogenetic analysis.
