Answer 1

Simple, unicellular organisms, no nucleus or membrane bound organelles. Genetic information in a loop called a plasmid. Has a cell wall, and moves using pili, flagella. Can form colonial organisms.

Question 3

What is a eukaryotic cell?

Schleiden and Schwann stated that cells are the smallest units of life, all living things are made of cells, and all cells come from pre-exisiting cells.

Question 5

What are some features unique to plant cells?

Answer 5

Cell wall, chloroplasts, large permanent vacuole

Answer 6

Centrioles, lysosomes
