Early cleavage divisions in most embryos are also rapid. One reason for this is that cleaving cells have a modified cell cycle, in which the two gap phases, G1 and G2 are completely omitted, and the cells cycle rapidly between M and S phases. In addition, because the major cytoskeletal systems of the cells are largely devoted to mitosis (microtubules) and cytokinesis (microfilaments) during rapid cleavage division, there is typically an antagonism between periods of rapid cell division and cell movement. Thus as the embryo approaches gastrulation, there is a tremendous slowing in the rate of division (note the slope of the curve at the right).
The cell would become turgid or swollen, in plant cells, the cell wall prevents the cell from bursting whereas in animal cells, the cell would burst, if that makes any sense
Answer:
Explanation:
1. From the atmosphere. The CO2 found in the atmosphere including ones expelled by animals during respiration is used in photosynthesis
2. From sunlight. During photosynthesis, plants utilize energy from the sun also known as solar energy converting it into chemical energy
3. The product which is glucose is metabolized in the mitochondria
4. The reduction of CO2 with it acting as an electron acceptor
5. Oxygen is a waste product of oxygenic photosynthesis wherein with oxidation of water, oxygen is produced as a byproduct
