A jellylike fluid inside the cell, where many cellular processes take place.

The control center of the cell, containing DNA and directing all cellular activities.

A complex of DNA and proteins, containing the instructions for building proteins.

A small, dense structure within the nucleus that makes ribosomes.

A storage compartment within a cell, holding materials like water, macromolecules, and waste products.

Small, membrane-bound sacs that transport materials within the cell.

A type of organelle filled with enzymes that break down macromolecules.

A network of fibers throughout the cytoplasm that helps maintain cell shape and facilitates movement.

Small, cylindrical structures in animal cells that play a role in cell division.

Tiny organelles responsible for protein synthesis.

A type of endoplasmic reticulum studded with ribosomes, involved in the synthesis of proteins that will be exported from the cell or embedded in its membrane.

A type of endoplasmic reticulum without ribosomes, involved in lipid synthesis and detoxification.

A cell organelle that modifies, sorts, and packages proteins and lipids for secretion or transport to other parts of the cell.

An organelle found in plant cells where photosynthesis takes place.

The powerhouses of the cell, converting food energy into a form that the cell can use.

A rigid layer that surrounds plant cells, protecting them and providing structural support.

A thin, flexible barrier that surrounds all cells, regulating what enters and leaves.

Rough endoplasmic reticulum, vesicles, Golgi apparatus, and the plasma membrane all work together to produce, package, and transport digestive enzymes.

Vacuoles store the food, and lysosomes contain the enzymes that break it down.

Multicellular organisms are organized in a hierarchical manner, from the largest (organism) to the smallest (atom).

Different levels of organization allow for specialization and a division of labor, increasing efficiency and complexity.

The plasma membrane is made up of two main components: lipids and proteins.

Permeable membranes allow substances to pass through, while impermeable membranes block them.

Positive feedback amplifies a process, causing an increase in the effect. Negative feedback counteracts a change, bringing the system back to a stable state.

Endocytosis is an active process that requires energy to transport substances across the membrane.

Osmosis is a type of passive transport that relies on a concentration gradient and does not directly require protein channels.

Diffusion and passive transport refer to the same process: the movement of substances from a high concentration to a low concentration without requiring energy.

Small, nonpolar molecules can easily pass through the membrane due to its lipid bilayer structure.

In a hypertonic solution, the concentration of solutes is higher outside the cell, causing water to move out of the cell and causing it to shrink.

In a hypotonic solution, the concentration of solutes is lower outside the cell, causing water to move into the cell and causing it to swell.
