Question
Photoautotrophs can synthesize sugar using inorganic source of carbon and sunlight as an energy source Bacterial cell walls are composed of polysaccharide similar to cellulose. Chemoheterotrophs synthesize sugar by ingesting inorganic sources of carbon and using the energy released from oxidation of reduced compounds. Endosymbiosis is the likely explanation for the evolution of the nuclear membrane. All members of the kingdom Fungi reproduce both sexually and asexually. A cephalized animal has sense organs concentrated at its dorsal end. A poikilohydric organism is one whose temperature varies with changes in the environment. Although plants excrete oxygen and animals excrete carbon dioxide, both plants and 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 arctic regions would tend to be more compact and rounder than those living in tropical regions. Gametes are produced in gametophytes that are part of a gametangial plant. Antheridia and archegonia are spore-producing structures on the sporophyte plant. Trees, including specimens such as maple, oak or spruce, are the haploid sporophyte portion of a life cycle. Both conifers and flowering plants are heterosporous, producing two kinds of gametophytes. The first vascular plants had a central core of vascular tissue made of fibers and continuous vessels.Explanation / Answer
1. This statemnet is true. Photoautotrophs synthesize organic food like sugars using inorganic molecules like carbon dioxide and water with the help of sunlight.
2. This statement is false. Bacterial cell walls are made up of peptidoglycan layer which is composed of polysaccharide which is different from the plant and fungi cell walls composed of cellulose.
3. This statement is false. Chemoheterotrophs are unable to fix carbon to form their own organic compounds.
