Pattern formation in plant embryos involves several morphogenetic steps, during which cell type specification, asymmetric cell division, and cell–cell communication play critical roles.
Answer:
A. Integumentary system
Explanation:
The integumentary system consists of the skin,hair and nail. This system consists of the largest organ in the body. The skin helps in protection against pathogens by shielding the internal body system from external objects.
The skin also helps in Vitamin D production through sunlight.
It also helps to prevent dehydration through regulation of water loss.
Answer: The correct answer is- Solar energy, carbon dioxide, and water.
Light dependent reactions comprise the first phase of photosynthesis (formation of food by green plants and algae in presence of sunlight) process.
This phase occurs in the thylakoid membrane of chloroplast.
During this phase, a green pigment chlorophyll absorbs energy from sunlight (in the presence of carbon dioxide and water) and convert it into chemical energy in the form of ATP and NADPH.
This energy is further utilized in the formation of food (glucose) in the next phase, which is a light independent phase of photosynthesis.
In photosynthesis, oxygen is produced by splitting of water molecule and it is released in the atmosphere.
Thus, solar energy, carbon dioxide, and water is the right answer.
