Unit 2 Quiz Plant Bio

Label parts of a phylogenetic tree

Label parts of land plant phylogenetic tree *some of the plant types have multiple features and because of the way this website works, you can't put multiple correct answers for a single spot, so for the parts that have several features, list them in alphabetical order from top to bottom if you want to get all the points for that question*

What makes a plant a plant?

Prokaryotic cells have a nucleus, large central vacuole, mitochondria, chloroplasts, and cell walls

Photosynthesis: takes places in [blank_start]chloroplasts[blank_end] and converts light energy to chemical energy by using [blank_start]carbon dioxide and water[blank_end] to produce [blank_start]oxygen and glucose[blank_end]

Indeterminate growth is a type of growth that starts from the middle of the plant and is finite

Do algae produce embryos?

Select all that are true for sporophyte generation

All the following are true for the gametyophyte generation EXCEPT

Embryophytes are also known as land plants

Embryophytes evolved from

Which of the following are advantages to terrestrial life?

A [blank_start]dessicating[blank_end] atmosphere means the air is drying

Special epidermal openings that can open and close, regulating gas exchange and restricting water loss

[blank_start]Spropollenin[blank_end] is a protective coating of spores and pollen

[blank_start]Cuticle[blank_end] is a waxy coating on surface of the plant that prevents plant from drying out

Which came first evolutionarily?

Which of the following apply to roots & rhizoids?

[blank_start]True roots[blank_end]: sophisticated structure containing vascular tissue, aiding in nutrient uptake, and anchoring plants in the ground [blank_start]Rhizoids[blank_end]: hair-like projections that help hold plants against the ground [blank_start]Vascular system[blank_end]: internal tissue that transports water & dissolved minerals throughout plant [blank_start]Lignin[blank_end]: rigid, woody compound that reinforces cell walls and acts as internal skeleton [blank_start]Stomata/pores[blank_end]: special openings in epidermis that allow gas exchange

All embryophytes are sporophyte-dominant except

What did fungi get in exchange for aiding ancestral plants in water & nutrient uptake?

Stomata were a necessary part of plant evolution because the [blank_start]cuticle[blank_end] blocks gas flow

Aquatic plants get structural support from buoyancy and pressure of water, land plants get structural support against gravity from [blank_start]lignin[blank_end]

Land has ___________ concentration of gasses & minerals compared to aquatic environment

A leaf having an internally branching system of veins, or a structure that is derived from such a leaf

A leaf having a single unbranched vein, or a structure that is derived from such a leaf.

What aided in the shift from gametophyte-dominance to sporophyte-dominance in embryophytes?

Bryophytes reproduce by dispersing small spores from their [blank_start]sporangium[blank_end]

Lycophytes reproduce via spores, but also bear small cones of sporangium called [blank_start]strobili[blank_end]
