Study Notes

The Nucleus

The nucleus contains DNA, essentially the "control center" of the cell.
The nucleus is surrounded by the nuclear envelope, which allows for the transport of materials into and out of the nucleus.
Within the nucleus is the nucleolus, which makes ribosomes, essential for protein synthesis.

Cytoplasm

The cytoplasm is the internal fluid of the cell containing various organelles.
Cytosol is the fluid portion of the cytoplasm surrounding organelles.

Organelles and their Function

The rough endoplasmic reticulum (ER) synthesizes membrane lipids and modifies proteins.
The smooth ER metabolizes lipids and detoxifies the cell.
Ribosomes are the sites of protein synthesis, utilizing the blueprints encoded in DNA.
The Golgi apparatus modifies and packages proteins after initial synthesis.
Mitochondria are responsible for the aerobic (oxidative) phases of cellular respiration, which generate ATP, the cell's energy currency.
Lysosomes break down waste products.
Centrioles are involved in chromosome movement during cell division.
Microtubules provide support and structure for the cell, being part of the cytoskeleton.
Cilia propel substances across the cell's surface, while microvilli increase surface area for absorption.

The Plasma Membrane

The plasma membrane is a semipermeable barrier that encloses the cell, regulating the passage of substances in and out.
Composed of phospholipids and proteins, it effectively creates a controlled environment for cellular processes to occur.

Animal Cell Structure

The image showcases the internal structures of an animal cell in a three-dimensional view.
Numerical labels from 1 to 15 are used to identify different parts of the cell.
Colors are used to differentiate organelles and membranes for visual clarity.
