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 Photoautotrophs can synthesize sugar using inorganic source of carbon and sunlight as an energy source -----------TRUE
THE energy source = light energy
carbon source = CO2
THEY can use Calvin-benson cycle to fix CO2 into organic compounds
-in cyanobacteria (oxygenic) or in bacteria (anoxygenic)
2. Bacterial cell walls are composed of polysaccharide similar to cellulose. -FALSE
Bacterial cell walls are different from the cell walls of plants and fungi which are composed of cellulose and chitin,
3. Chemoheterotrophs synthesize sugar by ingesting inorganic sources of carbon and using the energy released from oxidation of reduced compounds.-TRUE
4. Endosymbiosis is the likely explanation for the evolution of the nuclear membrane.-FALSE
5. ALL memebers of the kingdom fungi reproduce both sexually and asexually- TRUE
6. a cephalized anaimal has sense organs concentrated at its dorsal end ----TRUE
12. gametes are produced in gametophytes that are part of a gametangial plant-true
=====================
In bryophytes , the gametophyte is the most obvious phase of the life cycle. The bryophyte gametophyte is longer lived, healthfully free, and the sporophytes are commonly joined to the gametophytes and reliant on them.[2] When a greenery spore develops it develops to deliver a fiber of cells (called the protonema). The develop gametophyte of greeneries forms into verdant shoots that create sex organs (gametangia) that deliver gametes. Eggs create in archegonia and sperm in antheridia

Contagious propagation is perplexing, mirroring the distinctions in ways of life and hereditary cosmetics inside this differing kingdom of life forms. It is assessed that 33% of all parasites replicate utilizing more than one strategy for spread; for instance, multiplication may happen in two all around separated stages inside the life cycle of an animal groups, the teleomorph and the anamorph.[76] Environmental conditions trigger hereditarily decided formative expresses that prompt the making of particular structures for sexual or abiogenetic propagation. These structures help propagation by effectively scattering spores or spore-containing propagules.
Asexual reproduction
Agamic multiplication happens by means of vegetative spores (conidia) or through mycelial discontinuity. Mycelial fracture happens when a contagious mycelium isolates into pieces, and every segment develops into a different mycelium. Mycelial fracture and vegetative spores keep up clonal populaces adjusted to a particular specialty, and permit more quick dispersal than sexual propagation. The "Parasites imperfecti" (growths without the ideal or sexual stage) or Deuteromycota contain every one of the animal types that do not have a noticeable sexual cycle. Deuteromycota is not an acknowledged ordered clade, and is currently interpreted as meaning basically parasites that do not have a known sexual stage.
Sexual propagation
Sexual generation with meiosis has been specifically seen in all contagious phyla aside from Glomeromycota ] (hereditary examination recommends meiosis in Glomeromycota too). It contrasts in numerous perspectives from sexual multiplication in creatures or plants. Contrasts likewise exist between contagious gatherings and can be utilized to separate species by morphological contrasts in sexual structures and regenerative procedures. Mating tests between contagious separates may distinguish species on the premise of natural species ideas. The major parasitic groupings have at first been outlined in light of the morphology of their sexual structures and spores; for instance, the spore-containing structures, asci and basidia, can be utilized as a part of the recognizable proof of ascomycetes and basidiomycetes, separately. A few animal types may permit mating just between people of inverse mating sort, though others can mate and sexually repeat with whatever other individual or itself. Types of the previous mating framework are called heterothallic, and of the last homothallic
