Cell Structure and Organelles

Front

Selectively permeable barrier that controls what enters and leaves the cell.

Back

Cell membrane: A biological membrane that separates and protects the interior of all cells from the outside environment.

Front

Produces energy in the form of ATP for the cell.

Back

Mitochondria: Known as the powerhouse of the cell, mitochondria convert nutrients into energy.

Front

Prokaryote ___

Back

are unicellular: Prokaryotes are single-celled organisms that lack a nucleus.

Front

A small structure in a cell that is surrounded by a membrane and has a specific function.

Back

Organelle: Specialized structures within a cell that perform distinct processes.

Front

Transports materials throughout the cell. Acts as an assembly line for proteins.

Back

Endoplasmic reticulum: A network of membranes involved in protein and lipid synthesis.

Front

The control center of the cell that contains genetic material.

Back

Nucleus: The membrane-bound organelle that houses the cell's DNA.

Front

Organelles that contain digestive enzymes to break down waste materials and cellular debris.

Back

Lysosomes: Known as the 'clean-up crew' of the cell.

Front

The rigid outer layer of a plant cell that provides structure and support.

Back

Cell wall: A protective layer that gives the cell its shape and rigidity.

Front

The site of protein synthesis in the cell.

Back

Ribosome: Small structures that read mRNA and assemble amino acids into proteins.

Front

Organelles that convert sunlight into chemical energy through photosynthesis.

Back

Chloroplasts: Found in plant cells, these organelles contain chlorophyll.
