You are safe here, where we aim very high and understand that failure is a normal part of our success. Come think bravely with us.

Dynamic membrane remodeling is one of the cell's most important adaptations!
It creates dynamic signaling interfaces that change stress responses and cell fates

Quickly Moving Membranes
Because plants do not change their behaviors to adapt to changes in the world around them, they must do so biochemically. As a result, on the chemical level, they are sometimes moving much faster than animals...
CELLS ARE DEFINED BY THEIR MEMBRANES
Most of what we see when we look at pictures of cells is membranes!
Membranes are important because they allow cells to interact with their environment and separate parts of the cell from each other. Without these separate compartments, cells could not function as efficiently, and eukaryotic cells could not function at all. Just a small amount of leakage from some organelle membranes is enough to cause cell death.
Membranes Are Defined by Their Lipids
And their proteins and other components, of course. But lipids are most responsible for determining fluidity, rigidity, and the ability of the membrane to fold flexibly.
They can be thought of like membrane building blocks. Different shapes result in membranes with different properties. That's why different organs, cells, and even organelles have different lipids!

Why is Cold Tolerance Critical for Crops?
In this 3-minute February 2024 video from RFD-TV, Rebecca explains that most crops are from areas humans first lived in. They're not well adapted to cold because we brought them with us to warm regions. If they were cold tolerant, they'd grow earlier in spring, later in fall, and capture more energy to make more food.
