Saprophytes
30
How do fungi get their food?
The hyphal tips will release enzymes that eventually decompose and secrete the juices out of the dead creature the fungus has found
31
Where are saprophytic fungi found?
Dead trees, logs, plant little such as leaves, and even dead insects or animals, etc.
32
Histoplasmosis
Internal organs
33

Lichen
40
Scientific name for sac fungi:
Ascomycota
41
Scientific name for threadlike fungi:
Zygomycota
42
Scientific name for club fungi
Basidomycota
43
Scientific name for imperfect fungi
Deuteromycota
44
What are two characteristics that all plants have in common?
Plants make their own food through photosynthesis. All plants have cell walls made of cellulose which support and protect the cell.
45
What type of organism is thought to be the ancestor of all plants? Why?
Green algae- contain chlorophyll, cell walls, store energy in the form of starch, have a two part life cycle.
46
How are ferns, horsetails, and club mosses different from angiosperms?
Don't produce seeds, flowers, or fruits
47
How are horsetails and club mosses similar to ferns?
Release spores, vascular, don't make seeds
48
Why don't mosses ever grow as large as ferns?
Mosses don't grow lengthwise because they don't have a vascular system. Because they don't have a vascular system, they need to get water directly from their environment or from a neighboring cell. To get water, you need to be on the ground.
49
The ______ is a waxy layer that coats the surface of stems and leaves.
Cuticle
50
Seedless vascular plants include ferns, horsetails, and __________.
Club mosses
51
If plants did not possess a cuticle, where would they have to live?
Plants would have to live in moist areas so that they would not dry out.
52
Diagram that depicts evolutionary relationships among groups
Cladogram
53
Study of evolutionary relationships
Phylogeny
54
Grouping individuals by their pattern of evolution
Evolutionary classification
55
A form of analysis that looks at features of organisms that are considered innovations
Cladistics
56
In cladograms, more advanced characteristics appear in later species than in earlier ones. These are called
Derived characters
57
What is photosynthesis?
Carbon dioxide and water combine with solar energy and make glucose (food) and oxygen
58
Where does photosynthesis occur?
In the thylakoids of the chloroplasts which are in green leaf cells
59
What are chloroplasts and where are they found?
Chloroplasts are organelles found in green leaves of a plant. They make food for the plant through photosynthesis

65
Where does the water come from?
Roots absorb water through the xylem

Protists may be autotrophic, heterotrophic, or mixotrophic organisms: Autotrophic: Heterotrophic: Heterotrophic:
Autotrophic- photosynthetic: plant like Heterotrophic- ingestive: animal like Heterotrophic- absorptive: fungus like Mixotrophic organisms combine photosynthesis and food ingestion
96
Some Protozoa move with cilia
Cilia are hairlike structures on the sides of some protists which helps them to swim and capture food
97
Contractile vacuole
Pump that will contract and pump excess water out of the cell
98
Ameba extends pseudopodia around food particle until they join, enclosing the particle in a membrane-bound vesicle. A lysosomes merges with the new food vacuole, dumping its enzymes in to digest the food. The products of digestion are then absorbed through the membrane.
