Cell Structure and Function Quiz

Study Notes

Cell Structure and Function

Cells are enclosed by a plasma membrane, a selective barrier controlling nutrient entry and waste exit.
The cell's interior is organized into specialized compartments called organelles, each enclosed by a membrane.
The nucleus, a major organelle, houses genetic information essential for cell growth and reproduction.
Each cell contains one nucleus, while other organelles exist in multiple copies within the cytoplasm.
Mitochondria are responsible for energy transactions vital for cell survival.
Lysosomes break down unwanted materials within the cell.
The endoplasmic reticulum and Golgi apparatus play crucial roles in cellular organization by synthesizing, processing, sorting, and directing molecules to their designated locations.
Plant cells possess chloroplasts, responsible for photosynthesis, using sunlight to convert carbon dioxide and water into carbohydrates.
The space within the cytoplasm, called cytosol, contains the cytoskeleton, a framework of fibrous molecules that provides cell shape, enables organelle movement, and facilitates cell movement itself.
The cytosol also houses over 10,000 different molecules involved in cellular biosynthesis, the process of creating large biological molecules from smaller ones.

Cell Structure

Cells are enclosed by a plasma membrane, acting as a selective barrier for nutrients and waste products.
The cell's interior is organized with specialized compartments called organelles, each enclosed in a membrane.
The nucleus, a major organelle, holds genetic information for cell growth and reproduction.
Each cell has one nucleus, while other organelles like mitochondria, lysosomes, the endoplasmic reticulum, and the Golgi apparatus occur in multiple copies within the cytoplasm.
Mitochondria are responsible for energy transactions crucial to cell survival.
Lysosomes digest unwanted materials within the cell.
The endoplasmic reticulum and Golgi apparatus synthesize, process, sort, and direct molecules to their proper locations within the cell.
Plant cells additionally contain chloroplasts, responsible for photosynthesis, converting carbon dioxide and water into carbohydrates using sunlight energy.
The space between organelles in the cytoplasm is called the cytosol.
The cytosol contains the cytoskeleton, a framework of fibrous molecules providing cell shape, enabling organelle movement, and facilitating cell movement.
The cytosol contains over 10,000 different molecules involved in cellular biosynthesis, the process of creating large biological molecules from smaller ones.
