Question

12 like some traits in other plants, spider plant traits can change over time through the process of natural selection. which trait change would most likely affect both the pollination and the probability that future generations of spider plants will survive? a a change in the number of pups per plant b a change in the color of the leaves c a change in the shape of the flowers d a change in the size of the seeds

Explanation:

To solve this, we analyze each option:

• Option A: Number of pups (plantlets) affects reproduction but not pollination directly. Pollination involves flower - related traits for transferring pollen.
• Option B: Leaf color is related to photosynthesis or camouflage (if applicable to pests), not pollination. Pollinators are attracted to flower - related features like shape, color (of flowers), scent, etc.
• Option C: Flower shape is crucial for pollination. Different pollinators (e.g., bees, hummingbirds) have different adaptations to access nectar/pollen from flowers of specific shapes. If the flower shape changes, it can either attract or repel pollinators. If pollination is affected, the production of viable seeds (which lead to future generations) is also affected, thus impacting the survival of future generations.
• Option D: Seed size affects the viability or dispersal of seeds but not the pollination process, as pollination occurs before seed formation (involving flowers).

Answer:

C. a change in the shape of the flowers
