Answer:
The correct answer is - B. Enzyme.
Explanation:
RubisCo or ribulose bisphosphate carboxylase is an enzyme and most abundant protein on the earth that catalyzes the formation of the sugars from the CO2 by the photosynthesis process.
As it is given that in absence of the RuBisCo enzyme the cells plants or the photosynthetic organisms are not able to produce as much food as they produce in presence which means it has an essential role in increase the photosynthetic process to produce the food. By this, we can say it is an enzyme that helps in the process of photosynthesis.
Answer:
B. absorb water and vitamins
Explanation:
The large intestine is used to absorb water and vitamins while the other forms of absorbtion occurs in the small intestine.
Producers are organisms (usually plants) that utilize photosynthesis to produce their own food supply.
Photosynthesis is a process that uses photons from the sunlight to turn glucose and oxygen into carbon dioxide and energy. It basically is a process that uses light energy to make a usable food source, and it takes place in the cells of a chloroplast.
Chlorophyll is a green pigment found inside of plants' chloroplasts that absorbs light photons, allowing photosynthesis to take place.
Answer:
Cells, like humans, cannot generate energy without locating a source in their environment. However, whereas humans search for substances like fossil fuels to power their homes and businesses, cells seek their energy in the form of food molecules or sunlight. In fact, the Sun is the ultimate source of energy for almost all cells, because photosynthetic prokaryotes, algae, and plant cells harness solar energy and use it to make the complex organic food molecules that other cells rely on for the energy required to sustain growth, metabolism, and reproduction (PIC 1).
Cellular nutrients come in many forms, including sugars and fats. In order to provide a cell with energy, these molecules have to pass across the cell membrane, which functions as a barrier — but not an impassable one. Like the exterior walls of a house, the plasma membrane is semi-permeable. In much the same way that doors and windows allow necessities to enter the house, various proteins that span the cell membrane permit specific molecules into the cell, although they may require some energy input to accomplish this task (PIC 2).
