”Protists” refers to eukaryotic organisms that are not _______?

Plants, animals, fungi


100

The _____ hypothesis is applied to the nuclear envelope

Infoldings

100

Plants acquire energy through ______________

Photosynthesis

100

T/F: plants that exhibit alternation of generations only represent sexually

False. While alternation of generations is the sexual life cycle, these plants can also reproduce asexually. 

100

Plants are green because of _______

Chlorophyll (in chloroplasts)

200

Amoeba like movement refers to what mode of locomotion?

Pseudopodia, “fake feet”

200
In an organism that obtained chloroplasts via secondary endosymbiosis, you would expect to see ________

≥3 membrane layers

200

This lineage of plants is known to be flower bearing

Angiosperms

200

A male gametophyte produces _______

Male gametes - sperm

200

This lineage of plants is known to be cone bearing

Gymnosperms

300

______, _______ & _______ are nutritional modes of protists

absorption, ingestion & photosynthesis

300

The purpose of the mitochondria is to provide it’s host cell with _______

Adenosine Triphosphate (ATP), cellular energy

300

Vascular seedless plants are _________ dominant

Sporophyte

300

This process is known as a “reductive devision” and is directly involved with making spores.

Meiosis

300

The first cell wall layer in plants is cellulose, what is the second layer made of?

Lignin

400

Primary production by photosynthetic protists are “primary” because they:

Produce chemical energy by fixing CO2​​​​
400

As evidence for the infoldings hypothesis, the ______ and the endoplasmic reticulum are ______

Nuclear envelope, continuous

400

Color of flowers is something we would classify as _____________

Secondary attractant

400
On the plant phylogenetic tree we look at in class, what is the first lineage to experience alternation of generations?

Common ancestor of mosses and on. Not green algae clade. 

400
Collectively referred to as ‘Bryophytes’, these plants are _______, and therefore lack _______

non-vascular, vascular tissue, 

500

______ is a lineage of protists that is closely related to the disease Malaria.

Apicomplexans, Plasmodium, ALVEOLATA.


500

Name 3/5 pieces of evidence for mitochondria evolving via endosymbiosis

1)     have double membranes

2)     are similar in size to bacteria

3)     replicate by fission (like bacteria)

4)     have own ribosomes to make proteins (more similar to bacterial ribosomes) 

5)     have own genomes (circular like bacteria)

500

Why have biologists hypothesized that early land plants had low sprawling growth habits?

They were tied to water for reproduction, and thus needed to remain in close contact with the moist soil. Also lacked vascular tissue and structural support. 

500

Alternation of generations requires _____________ h____ and d______ phases

Multicellular, haploid, diploid
