Multi-cellular
Eukaryotic
Have cell wall and chloroplast
Autotroph

17
Q

Characteristics of Fungi kingdom

A

Heterotroph
Have Cell Wall
Can reproduce in both ways (sexual and asexual)

18
Q

Cell Theory

A

All living things are made of cells
Cells are the basic unit of life
All cells come from other cells

19
Q

Theory of spontaneous regeneration

A

Idea that non-living matter can give rise to living organisms

Pasteur boiled a meat broth in a flask that had a long neck that curved downward, like a goose. The idea was that the bend in the neck prevented falling particles from reaching the broth, while still allowing the free flow of air. The flask remained free of growth for an extended period

20
Q

STEM cells

A

The body’s foundation, as they are the only cells that can create specialized cells

Stem cells are used in healthcare to treat blood disorders and blood cancer
