Answer:
Chemoautotrophs.
Explanation:
Autotrophs may be defined as the organism that can prepare their own food with the help of chemical and light. Two types of autotrophs are chemoautotroph and photoautotrophs.
Chemoautotrophs are the organisms that can prepare their own food with the help of chemicals. The bacteria living around deep sea and hot water vents are considered as chemoautotrophs because they prepare their food with the help of carbon present in their surroundings.
Thus, the correct answer is option (A).
Answer:
C. primary cell wall → plasma membrane → cytoplasm → vacuole.
Explanation:
Every molecule or particle which enters into a cell, it must pass through several cellular structure at different level means it also depends on the type of molecule like size, shape, and nature (characteristics). On the surface of root cell, potassium ion pass through the primary cell wall which is most outer layer of plant cell, then it passes the second layer called plasma membrane, in the plasma membrane cytoplasm is present and when potassium ion reaches the cytoplasm then it will enter into the vacuole present in cytoplasm.
There are inner part of the stem and outer part of the stem; in a plant the inner part supports the movement of the water and nutrients. You stop the flow of the vital elements of plant growth when you snap the stem and this is the reason why the plant die due to starvation of the nutrients.
