Question

can you some check if this is right

Heating a dish of Volvox carteri to temperatures resembling late summer pond conditions will lead to what event? Sperm packets Sexual development of gonidia Sexual inducer Sperm Modified embryonic Sexual male Asexual male Gonidium development of gonidia resulting in gamete production Sexual zygotes inducer Egg Sexual female Asexual female Meiosis and germination DEVELOPMENTAL BIOLOGY Eighth Edition, Figure 29 o2006 snauer Associates Inc. O immediate release of sperm asexual reproduction O o induction of the sexual inducer protein o fusion of egg and sperm

Explanation / Answer

1.sex inducing phermone induces hydroxyproline which extracellular matrix causes volvo ells attach each other phermones also produces additional cells incorporate glycoprotiens these glycoproteins collect positively charged sex inducing phermones to gonidia same protein induced by wounding of volvox brain and spinal cord derived from neural tube during embryogenesis structure get formed thick region called ectoderm formed is neural platewhich is converted to tube in vertebrates process involves shaping and folding of neuroepithelum these folds undergo fusion so folding,shaping and elevation are primary steps involved cohesive forces are responsible for surface tension it is the least surface tendency which acquire low space it is the physical quantity that determines cell sorting but not only surface tension that determines sorting     EPITHELIAL AND MESENCHYMAL CELLS in embryo these are two main types of cells epithelia serves as barrier for outer environment ,mesenchymal cells attaches one another by focal contacts wings of butterfly and wings of bat are analogous NOTOCHORD it plays an important role in formation of neural tube folding of neural tube to form actual tube occurs in different stages and these notochord is adjacent tostomite at fourth stage ,endoderm and neural tube specification by interaction between cells represents conditional specification neural crest cells can migrate to form pigment cells ,neuranal cells and adrenal cells neural cells form different number of cell types which are glial cells of sensory,nervous systems,medulla cells of adrenal gland,pigment containing all cells of epidermis and many skeletal connecting tissues
