How do plants keep their roots cozy? #shorts #science #SciShow

In winter, plant cell liquids can freeze, damaging roots. Alfalfa combats this by converting starch into antifreeze sugars, forming barriers between cells to trap water and prevent ice formation. This process lowers the freezing point of the liquid, avoiding harmful icicles. However, these protective measures require significant energy, which limits plant growth during winter.

What happens to the liquid between plant cell walls during winter?

• It evaporates completely.

• It becomes more viscous.

• It remains unchanged.

• It turns into ice, potentially damaging the roots.

How do plants like alfalfa protect themselves from freezing?

• By growing thicker roots.

• By converting starch into antifreeze sugars.

• By absorbing more sunlight.

• By shedding leaves.

What role do extra sugars play in plant cells during winter?

• They form barriers to prevent ice formation.

• They help the plant absorb more water.

• They increase the plant's growth rate.

• They make the plant more colorful.

Why is the freezing point of the liquid in plant cells lowered?

• To make the plant more flexible.

• To prevent the formation of damaging icicles.

• To enhance photosynthesis.

• To increase the plant's height.

Why do plants show less growth during winter?

• Because they are dormant.

• Because they lose their leaves.

• Because they receive less sunlight.

• Because they use a lot of energy for damage control.
