Hilum
Micropyle
Chalaza
Integument
Which of the following structures connects the ovule to the placenta within the ovary?
Funicle
Hilum
Micropyle
Nucellus
The scar left on the seed coat after the ovule detaches from the funicle is called the:
Hilum
Micropyle
Raphe
Aril
In an angiosperm ovule, which structure is responsible for transporting nutrients from the placenta to the developing embryo sac?
Funicle
Integument

Which of the following plant-insect relationships exhibits obligate mutualism, where neither organism can complete its life cycle without the other?
Yucca plant and Yucca moth
Fig and wasp
Orchid and bee
Mango and fruit fly
The Yucca plant relies on a specific species of moth for pollination. What type of symbiotic relationship is exemplified by this interaction, considering that the moth larvae also depend on the Yucca plant for food?
Commensalism
Parasitism
Obligate Mutualism
Predation
If the Yucca moth population were to drastically decline, what would be the most likely impact on the Yucca plant population?
Increase in Yucca plant population
No impact on Yucca plant population
Decline in Yucca plant population
Increased genetic diversity in Yucca plants
Which statement best describes the relationship between the Yucca plant and the Yucca moth?
The moth parasitizes the Yucca plant.
The Yucca plant provides a habitat for the moth, but they are not dependent on each other.
They exhibit commensalism, where one benefits and the other is unaffected.
They exhibit obligate mutualism, with each species fully dependent on the other.
