Answer: The structure is chloroplast.
Explanation: Photoautotrophs are organisms that can synthesize food using light energy and carbon dioxide via photosynthesis.
Photoautotroph is a combination of two words: photo which means light and autotroph which means an organism that can manufacture its own food.
A photoautotroph manufactures its own food in a process known as photosynthesis. Photosynthesis is a process by which plants manufacture organic foods such as glucose using light energy, carbon dioxide and water. This process takes place in the chloroplast. A chloroplast is an organelle found in plant cells that contains chlorophyll which is the pigment that absorbs the light used in photosynthesis.
Answer:
The correct answer is: B. pure culture.
Explanation:
- Sputum sample contains varied types of bacteria.
- When this sample is cultured on a growth medium all the different types of bacteria grow on it.
- A single distinct colony of bacteria is formed from by multiple divisions of a single bacterial cell.
- In the given growth medium distinct colonies of bacteria are formed.
- Each such colony is formed from a single bacteria.
- When such a single distinct colony is inoculated in a separate medium and bacteria is grown in that, then a Pure culture of bacteria is generated.
- A Pure culture can be defined as such a culture which is comprised of single type of bacterial cell, formed from a single bacteria.
