◉ Reproduction can occur ____ or ____ Answer: Sexually or asexually
◉ What does sexual reproduction involve? Answer: Fusion of two
gametes that unite and grow into new offspring
◉ What does asexual reproduction produce? Answer: New offspring
from a single organism
◉ What are examples of asexual reproduction? Answer: Spore
formation, binary fission, vegetative reproduction, budding,
fragmentation

plans, fungi
◉ What organisms use binary fission? Answer: Prokaryotes and
some eukaryotic protozoa like amoeba
,◉ What organisms use budding? Answer: Fungi, bacteria, some
plants, fewer animals

and echinoderms like starfish
◉ How can the levels of biological organism be described? Answer:
Successive, broadest to smallest

◉ What is an organ system? Answer: A group of organs classified as
a unit because of shared functions
◉ What are organs? Answer: Individual structures composed of two
or more tissue types that perform a common function
◉ What are tissues? Answer: A group of similar cells and the
immediate environment surrounding them
◉ What determines the function of the tissue type? Answer: Unique
cell types and extracellular environments
