Cells And Heredity Flashcards
Microscope
An instrument that uses glass lenses to magnify an object.
Cytoplasm
A thick, gel like material contained within the cell membrane. Most of the work of the cell is carried out in the cytoplasm.
Prokaryotic Cell
A cell that lacks a nucleus and other organelles, with DNA that is not organized into chromosomes.
Chloroplast
An organelle in a plant cell that contains chlorophyll, a chemical that uses energy from sunlight to make sugar
Tissue
A group of similar cells that are organized to do a specific job.
Unicellular
A term used to describe an organism that is made up of a single cell
Bacteria
A large group of one-called organisms that sometimes cause disease.
Nucleus
The structure in an eukaryotic cell that contains the genetic material a cell needs to reproduce and function.
Organelle
A structure in a cell that is enclosed by a membrane and that performs a particular function.
Mitochondria
Organelles that release energy by using oxygen to break down sugars
Organ
A structure in a plant or an animal that is made up of different tissues working together to preform a particular function.
Multicellular
A term used to describe an organism that is made up of many cells.
Cell membrane
The outer boundary of the cytoplasm, a layer that controls what enters or leaves the cell, a protective covering enclosing an entire cell.
Eukaryotic cell
A cell in which the genetic material is enclosed within a nucleus, surrounded by its own membrane
Cell wall
A protective outer covering that lies just outside the cell membrane of plant cells.
