1. The nucleus
The nucleus is often considered to be the cell's control center. It contains the cell's genetic material and directs the cell's activities.
2. The cytoplasm
The cytoplasm consists of everything inside the plasma membrane of the cell. It contains various Organelles and provides a medium for cellular processes.
3. The selectively permeable barrier
The plasma membrane forms a selectively permeable barrier between the inside and outside of the cell. It controls the movement of substances into and out of the cell.
4. The cytoskeleton
The cytoskeleton is essentially a "skeleton" inside the cell. It provides shape, structure, and support to the cell.
5. Ribosomes
The rough endoplasmic reticulum is covered with ribosomes. Ribosomes are responsible for protein synthesis.
6. Enzymes
Lysosomes use enzymes to break down foreign matter and dead cells. They are involved in cell digestion and waste disposal.
7. Plant
Plant cells specifically have a cell wall, a large central vacuole, and chloroplasts.
The cell wall provides structural support, the central vacuole stores water and nutrients, and chloroplasts are involved in photosynthesis.

The current understanding of dark matter is largely theoretical due to its nature of not directly interacting with electromagnetism. It can be inferred to exist due to its gravitational effects, representing about 27% of the universe's mass-energy composition. The key candidate for it is Weakly Interacting Massive Particles, suggested by the Supersymmetry theory.
Our current understanding of the nature of dark matter is largely theoretical, as dark matter does not interact with the electromagnetic force and cannot be seen directly with telescopes. However, it is inferred to exist due to its gravitational effects on galaxies and galaxy clusters. Dark matter constitutes about 27% of the universe's mass-energy composition, vastly outweighing ordinary matter. The leading candidate for dark matter is currently the Weakly Interacting Massive Particles, or WIMPs. The existence of WIMPs is suggested by the Supersymmetry theory in particle physics, and several experiments are ongoing to detect WIMPs directly.
