Cellular Organization Flashcards

These vocabulary flashcards cover the different types of cellular organization, including unicellular, multicellular, and colonial forms, as discussed in Unit 1.

Unicellular organisms

Organisms that are made of only one cell.

Multi-cellular organisms

Organisms that are made of many cells.

Colonial form of organism

A configuration where certain unicellular organisms live in groups and make colonies.

Unicellular examples

Organisms such as Amoeba, Chlamydomonas, and Euglena.

Division of labour (Unicellular)

The distribution of work among different organelles within a single-celled organism.

Vital activities of life

The capacity of a single cell to carry out respiration, digestion, excretion, and reproduction independently.

Volvox

A green alga that lives in water and is a common example of a unicellular colonial organism.

Volvox Colony Organization

A structure where hundreds of volvox cells make a small colony, and many small colonies make a big colony.

Cellular Dependence in Colonies

The state in which individual cells (like those in a Volvox colony) cannot live independently because they rely on each other for specialized tasks.

Division of labour (Colonial)

A trend towards complex organization where specific cells are specialized for functions like mobility or reproduction.
