Question
Photoautotrophs can synthesize sugar using inorganic source of carbon and sunlight an energy source Bacterial cell walls are composed of polysaccharide similar to cellulose. Chemoheterotrophs synthesize sugar by ingesting inorganic sources of carbon and the energy released from oxidation of reduced compounds. Endosymbiosis is the likely explanation for the evolution of the nuclear membrane. Proglottids are reproductive parts of the tapeworm. Poikilohydric organism is one whose temperature varies with changes in the environment. Although plants excrete oxygen and animals excrete carbon dioxide, both plants animals generally excrete a nitrogenous waste. The apoplast of plants is analogous to the intercellular fluid of animals. Ectothermic organisms are also homoeothermic. To conserve heat, plants and animals living in arctic regions would tend to be compact and rounder than those living in tropical regions. The endosperm is the main food storage organ in a ripe peanut seed. Antheridia and archegonia are spore-producing structures on the sporophyte Trees, including specimens such as maple, oak or spruce, are the haploid portion of a life cycle. Both conifers and flowering plants are heterosporous, producing two kinds gametophytes. The first vascular plants had a central core of vascular tissue made of continuous vessels. Plants, like animals, maintain internal homeostasis.Explanation / Answer
The question is for whether true or false.
1. True, photoautotrophs carry out photosynthesis using sunlight, carbon from inorganic source i.e carbon dioxide and convert them into organic materials.
2. False, bacterial cell walls are made up of peptidoglycan which is made from polysaccharide chains cross-linked by unusual peptides containing D-amino acids.
3. False, chemoheterotrophs utilize inorganic energy sources like sulfur or utilize organic energy such as carbohydrates, lipids, and proteins.
4. False, Endosymbiotic theory describes about the host cell and igested bacteria could easily dependent on one another for survival resulting in permanent relationship. It describes about the mitochondria and chloroplast have become more specialised from the process of evolution.
5. True, each sefment in the tapeworm containing sexually mature reproductive system.
6. True, poikilothermic organism whose internal temperature varies considerably.
