Biology Chapter 32 (3.1 - 3.2)

Create food through photosynthesis - Plants are autotrophic

Fungi are heterotrophs that grow on or near their food, fungi obtain nutrition through absorption

Animals are heterotrophs that obtain nutrition through ingestion and enzymes break down the food within their bodies

Similarity - For the most part plants, animals, and fungi are all multicellular
Difference - Most animals have two types of specialized cells not found in plants or fungi; muscle cells and nerve cells

ZYGOTE undergoes series of mitotic divisions called cleavage
EIGHT-CELL embryo is formed by three rounds of cell division
In most animals cleavage produces a BLASTULA (hollow ball of cells that surround a cavity called the BLASTOCOEL)
animals undergo GASTRULATION (one end of the embryo folds inward, expands and eventually fills the blastocoel) creating the endoderm and the ectoderm
Pouch formed by the gastrulation is called the ARCHETERON opens to the outside via the blastopore
Endoderm of the archeteron develops into the tissue lining the animals digestive tract

A sexually immature form of an animal that is morphologically different from an adult.

Turns the animal into a juvenile that resembles an adult but is not yet sexually mature.
