Let's learn about the structure and function of the eukaryotic cell's nucleus. Discover the role of the outer and inner membranes, the nucleoplasm, and the nuclear pore in isolating the …
Nucleus and ribosomes (article) | Khan Academy
Structure and function of the nucleus and ribosomes of a cell. How they work together in the production of proteins.
Intro to eukaryotic cells (article) | Khan Academy
Overview of eukaryotic cells and how they differ from prokaryotic cells (nucleus, organelles, and linear chromosomes).
Cellular organelles and structure (article) | Khan Academy
The nucleus itself is filled with liquid (called nucleoplasm) and is similar in structure and function to cytoplasm. It is here within the nucleoplasm where chromosomes (tightly packed strands of …
Cell parts and functions (article) | Khan Academy
Learn about the structure and function of the cell membrane, nucleus, ribosomes, mitochondria, chloroplasts, and vacuoles.
Cell parts and functions (article) | Khan Academy
The nucleus is an organelle that contains a cell’s genes. Chloroplasts are organelles that carry out photosynthesis, which makes the food plant cells need to live.
Prokaryotic cells (article) | Khan Academy
The majority of prokaryotic DNA is found in a central region of the cell called the nucleoid, and it typically consists of a single large loop called a circular chromosome. The nucleoid and some …
Prokaryote structure (article) | Khan Academy
Eukaryotic cells have a nucleus, a membrane-bound chamber where DNA is stored, while prokaryotic cells don't. This is the feature that formally separates the two groups.
The cell cycle and mitosis (article) | Khan Academy
A diagram summarizing the two primary phases of the cell cycle. During interphase, the cell grows and each chromosome is replicated. During the mitotic phase, the chromosomes are equally …
Protons, neutrons, and electrons in atoms - Khan Academy
Let's take a look at the simplified diagram to learn more about these subatomic particles and the structure of an atom. In the center of an atom, we have the nucleus, which is composed of …
