When an atom has fewer neutrons than protons and more electrons than protons, such an atom is said to be an anion. Hence, it is negative ion.
Depending on the number of proton and electron, there are 3 types of atoms:
In this case, the atom has more electrons than protons and, therefore, is an anion. The excessive electron makes such atom to be negatively charge.
Therefore, an atom that has fewer neutrons than protons and more electronsthan protons is a negative ion.

The process of photosynthesis requires water, carbon dioxide, sunlight and chlorophyll. The only cells that are capable of photosynthesis are the ones that contain chloroplast.
Plastids are cell organelles that are double membrane and generally found in plants and algae.
There are three types of plastids, namely
The cell that have chloroplast can perform photosynthesis, because it is the chlorophyll that enables this process by absorbing sunlight.
Thus, the only cells that are capable of photosynthesis are the ones that contain chloroplast.

D. taking in wastes from other cells
The correct answer is D. taking in wastes from other cells.
The correct answer is D. taking in wastes from other cells.
Homeostasis is the process by which cells, organisms, or systems maintain stable internal conditions. To achieve and maintain homeostasis, cells perform various processes such as making new molecules for growth, transporting substances across cell membranes, and breaking down unneeded molecules. However, taking in wastes from other cells does not contribute to maintaining homeostasis and is not a recognized process for this purpose.
